3 Corrective Maintenance

3.1 Introduction

The EAGLE trouble detection is distributed throughout the system. Each processor continually monitors its internal subsystems and certain external subsystems. Whenever a trouble condition changes state, the processor analyzes the change and stores the analysis for reporting to the active E5-MASP. The trouble detection software does not affect the service quality of the system.

Each E5-MASP is made up of two cards, the E5-MCAP card and the E5-TDM (terminal disk module).

The E5-MCAP card is equipped with 4 GB of physical application processor memory. The primary data interface to the E5-MCAP is RS-232 interfaces (i.e.: terminals) through the E5-TDM.

The E5-MCAP card contains one latched USB port for use with removable flash media (“thumb drive”), and one flush-mounted USB port for use with a plug-in flash drive. The removable media drive is used to install and back up customer data. The flush-mounted USB port is used for upgrade and could be used for disaster recovery. The removable flash media is used as a replacement for the legacy Magneto-Optic (MO) Drive. The E5-MCAP card is a replacement for the obsoleted legacy GPSM-II card used for the MCAP function.

Note:

The E5-MCAP card can not be used for the other functions for which the GPSM-II class (e.g.: MCP, IPS, DCM) card is used.

The E5-TDM card contains four major subsystems: the Terminal Processor Subsystem, the System Clock/Control Subsystem, the SATA Subsystem, and a Power Subsystem. These subsystems provide the EAGLE with 16 user-accessible terminals, distributes Composite Clocks and High Speed Source clocks throughout the EAGLE, distributes Shelf ID to the EAGLE, and disk storage for an E5-MCAP card. The E5-TDM card provides an interface to the E5-MDAL card for system alarms.

The E5-TDM card contains one fixed solid-state SATA drive that is removable and used to store primary and backup system databases, measurements, and Generic Program Loads (GPLs).

To determine which MASP is active either enter the rept-stat-db command, or enter the rept-stat-card command, or examine the LEDs on both E5-TDM cards. If the LED on the E5-TDM card is green, the associated E5-MASP is active. (If the LED on the E5-TDM card toggles between green and amber, the associated E5-MASP is standby.)

The output of the rept-stat-db command shows which E5-MASP is active with the indicator (ACTV) following the E5-TDM card location. The indicator (STDBY) following the E5-TDM card location shows which E5-MASP is standby.

The output of the rept-stat-card command shows which E5-MASP is active with the entry ACTIVE in the SST field for the E5-MCAP card. The entry STANDBY in the SST field for the E5-MCAP card shows which E5-MASP is standby.

The database commands, such as rept-stat-db, refer to the E5-TDM because the E5-TDM contains the fixed disk drive and the removable USB media for the E5-MASP.

3.2 System Alarm Levels

There are three levels of alarms in the EAGLE system. They are:

Critical
A critical alarm is an indication of a severe service affecting problem that can be related to traffic, billing, and maintenance capabilities and requires immediate maintenance attention, regardless of time of day.
Major
A major alarm is an indication of a problem that seriously affects system operation, maintenance and administration, etc. and requires immediate attention. The urgency is less than in critical situations because of a lesser immediate or impending effect on system performance, customers, and operating company operations and revenue.
Minor
A minor alarm is an indication of a problem that does not have a serious impact on service, and does not require immediate maintenance attention.

Note:

Some UAMs are considered informational if they satisfy the following conditions in the SNMP V2 traps generated by EAGLE E5OAM:
  1. The Alarm Level is stated as "No alarm condition" in this user's guide.
  2. The alarm is not intended to clear any higher severity UAM as per the corresponding UAM Balancing Matrix.
These UAMs are informational only and neither contribute to the total number of alarms in the system nor change the alarm state of the device on EAGLE.

3.3 Trouble Detection

The first step in analyzing a system trouble is to know when a trouble exists. The EAGLE handles this task through:

  • Audible alarms

  • Visual alarms

  • Event/error messages

Audible Alarms

The EAGLE has three types of audible alarms: critical, major and minor. Audible alarms are generated by the E5-maintenance disk and alarm card (E5-MDAL), and can be heard through the electronic sonalert device installed on the card. Each alarm has its own distinct cadence as described in the following:

  • Critical - Two tones 0.5 seconds apart, separated by 1.5 seconds of silence.

  • Major - Single tone, separated by 1.5 seconds of silence.

  • Minor - Single tone of 5 seconds or continuous tone for power plant alarm.

Visual Alarms

The EAGLE has several types of visual alarms. They are:

  • AlarmLEDs on the Fuse and Alarm Panel (FAP)

  • Alarms displayed on the system terminal

  • LEDs on application cards

  • End cabinet alarm indicators

Maintenance personnel usually see the alarm LEDs on the fuse and alarm panel (FAP) and the alarms displayed on the system terminal screen to alert them that a system problem exists. The LEDs on a card help maintenance personnel diagnose where a problem exists.

MDAL LEDs

Following are the five alarm LEDs on the face of the obsoleted MDAL card. Although the card is obsolete, the functionality remains uniform. See Figure 3-1:

  • Critical

  • Major

  • Minor

  • MASP-A

  • MASP-B

When the system detects an alarm, the appropriate alarm level and location (MASP-A or MASP-B) LEDs illuminate. See Figure 3-1.

Note:

Verify the state of the MDAL card by observing the LEDs on the face of the MDAL card. The fuse and alarm panel do not reflect any alarms caused by the MDAL card.

Figure 3-1 MDAL Alarm LEDs

img/c_trouble_detection_maintmanual-fig1.jpg

Alarm LEDs on the Fuse and Alarm Panel (FAP)

There are six alarm LEDs on the FAP that indicate:

  • Power alarm LEDs (A and B)

  • A critical alarm

  • A major alarm

  • A minor alarm

  • A fuse alarm

The FAP provides protected distribution of power to the system. Protection is provided by the fuses placed in the GMT fuse holders used in the panel. The FAP contains a fuse fail alarm circuit that operates when one or more of the panel’s fuses fail. An LED changes from green to red when a fuse has failed. The LED remains red until the fuse has been replaced.

The fuse and alarm panel uses GMT fuses for individual circuit protection (see Figure 3-2). The EAGLE uses 3A and 1A fuses, depending on the application. When a fuse fails due to an overload condition, a small colored flag on the fuse shows the position of the fuse that has failed. The flag is gray on 1A fuses, blue on 3A fuses, black/white on 7.5A fuses, and red on 10A fuses.

Figure 3-2 GMT Fuse


img/c_trouble_detection_maintmanual-fig2.jpg

The panel contains two separate circuits, A and B. Current flows from the input terminals to the fuse bus. When a fuse is installed in a fuse holder, the circuit is completed to the output connector. The Fuse Fail Alarm LED on the front panel indicates the condition of the panel. Green is indicated if power is applied to the panel and there are no failed fuses. The green LED changes to red when a fuse fails. An unlit LED indicates a failed LED or no power to the fuse and alarm panel.

The fuse and alarm panel is also equipped with frame alarm LEDs that display the critical, major, and minor alarms generated by the EAGLE system.

The fuse and alarm panels have the A and B buses connected through diodes to allow one bus to pick up the entire load when the other bus loses power.

Table 3-1, Table 3-2 and Table 3-3 describe the front panel configuration of the fuse and alarm panels.

Alarms appearing on a terminal screen

Three types of alarms may be displayed on a system terminal screen:

  • CRIT - Indicates a critical alarm

  • MAJR - Indicates a major alarm

  • MINR - Indicates a minor alarm

These appear as three highlighted boxes in the top left corner of a terminal. If an alarm condition exists, it is displayed in one of the highlighted boxes. There is a fourth box next to the three alarm boxes that is not used. To obtain information about the alarm, use the rept-stat-alm command at the system terminal, followed by a carriage return.

This command provides all current alarm status. Refer to Commands User's Guide for more information about the rept-stat-alm command.

Alarms on Application Cards

Each application card has LEDs that indicate the condition of the card. Alarm conditions appear on the card if the card has a fault. Refer to Installation Guide for the location and description of the card LEDs.

End Cabinet Alarm Indicators

There are three alarm LEDs on the end cabinet:

  • A critical alarm LED

  • A major alarm LED

  • A minor alarm LED

When an alarm condition is present, one or more of these LEDs illuminate in the signifying the overall system alarm level. Refer to Installation Guide for alarm indicators.

Event/Error Messages

Unsolicited messages are used in the EAGLE for trouble notification and to communicate the status of the system to Operations Services (OS). The EAGLE outputs two types of unsolicited messages.

  • Unsolicited Alarm Messages (UAMs) are used to denote a persistent problem with device or object that needs the attention of a craftsperson. Some examples are a link failure, a subsystem being out of service, or a card not receiving a system clock.

  • Unsolicited Informational Messages (UIMs) are indications of transient events that have occurred. UIM examples include messages that an MSU contains invalid data or failed a gateway screening function.

The location of a card with a fault is displayed with the event/error message. The location is displayed as a card number. Card numbers are used to locate the card in the EAGLE system. Refer to Installation Guide for card locations.

Following is an example of an event/error message displaying the card location:


     RLGHNCXA21W 00-02-07 12:01:43 EST  EAGLE 35.0.0
**  0014.0008  ** CARD 1113 OAM        Active MASP has become isolated

The card location always follows the word “CARD” in the message. In this example, the card number is 1113.

IMT Bus States

The states of the IMT bus are combined from the primary state (PST) and secondary state (SST) for each IMT bus. See Commands User's Guide for information about PST and SST states and definitions.

The rept-stat-imt command is used to report the status of the IMT bus. An example of the output follows:


RLGHNCXA03W 00-09-27 16:50:24 EST  EAGLE 31.5.0
IMT   PST             SST        AST
 A    IS-NR           Active     -----
 ALARM STATUS       = No alarms
 IMT   PST             SST        AST
 B    IS-ANR          Fault      -----
 ALARM STATUS       = **  0108 Major IMT Failure Detected
Command Completed.

IMT System Alarm Level Determination

The state of the IMT subsystem is determined from the state of each IMT bus. If both buses are IS-NR active, the IMT subsystem is IS-NR active. If only one IMT bus is manually disabled (IS-ANR manual), the IMT subsystem is IS-ANR manual. Otherwise, the IMT subsystem state is IS-ANR fault.

The alarm level of an IMT bus in the IS-ANR fault state is determined by how many bad card connections it has. The number of bad connections required for a major alarm or a minor alarm are as follows:

  • 0 failures = no alarm

  • 1-2 failures = minor alarm

  • 3 or more = major alarm

The alarm levels on the individual buses combine to give the overall alarm level for the IMT subsystem. Table 3-4 shows the rules that are used to determine the overall alarm level of the system of IMT buses.

3.4 Output Messages

The EAGLE generates output messages in response to command input or fault conditions in the EAGLE or in the network. The format for these messages is generally uniform. Some messages include additional data.

Network messages provide the text description of the event, and on the lines below the text line, any additional information.

The following example shows the general format of an output message.

Figure 3-6 Output Message Format

img/r_output_messages_maintmanual_fig1.jpg

The fields in an output message (shown in the figure above) are described next:

  • Host CLLI code - a maximum of one alpha character and ten alphanumeric characters. The CLLI code uniquely identifies the system in terms of its physical location. The CLLI code must be unique among all elements in the system.

    The CLLI code consists of the following:

    • City = 4 characters

    • State = 2 characters

    • Building = 2 characters

    • Equipment type = 3 characters

  • Date - The date the message was generated, in the format year-month-day.

  • Time - The time the message was generated with time zone, in the format hour: minutes: second time zone.

  • System Release Number - contains a system identifier and the version ID number. The system identifier, can be EAGLE or EAGLE5 depending on the product key enabled on the system. The version ID number has the software release specific GPL set that is expected to be installed on the system as approved loads. The format of the version ID number is in the form of maj.min.maint, defined as follows:

    • maj - the major release ID

    • min - the minor release ID

    • maint - the maintenance release ID

  • Alarm Level - a one or two character indicator of the alarm level, defined as follows:

    • *C = Critical Alarm

    • ** = Major Alarm

    • * = Minor Alarm

    • blank = No Alarm

  • Message Sequence Number - This number is an index for all output messages. The number increments sequentially for every message. The output messages originating from the card in location 1113 has a range from 0001 through 4999. The range for location 1115 is 5000 through 9999.

  • Message Reference Number - Messages that are associated with a specific action are numbered for reference. These messages are defined in this chapter, along with a corrective action.

  • Affected Device - The device that caused the message to be generated. This generally describes the card type.

Network messages with additional data display the additional lines below the text string and message reference number (MRN). See individual messages for examples of output.

All network messages are non-alarm and are used to notify the user of network events. There may or may not be a procedure associated with these messages.

3.5 Alarm Clearing Procedures

After an audible has sounded, it can be silenced by entering the following command:

rls-alm:lvl=xxxx

where xxxx can be:

  • minr - Silences a minor alarm
  • majr - Silences a major alarm
  • crit - Silences a critical alarm.

All alarm types can be silenced with the following command:

rls-alm

The rls-alm command does not clear visual alarms on the terminals or alarm indicators on the fuse and alarm panel (FAP) or frame panels.

Once an audible alarm is silenced, any new alarm conditions cause the alarm to sound again.

Silencing a specific alarm when a lower level alarm is also present results in the next highest audible alarm level being activated. For example, the system has both critical and major alarms present. When the critical alarm is silenced, the audible major alarm begins to sound.

3.6 Retrieve Trouble Report

Application maintenance software is responsible for monitoring trouble on a card. There are three types of troubles or faults:

  • Abnormal situation is being reported by software.

  • An SS7 message has a problem (an invalid DPC, for example)

  • A hardware fault is being reported.

Trouble reports are used by My Oracle Support (MOS) to help analyze problems with the EAGLE system. To help My Oracle Support (MOS), retain any printouts of the trouble report. The output of the rtrv-trbl command should be reviewed with a member of My Oracle Support (MOS). To display the current trouble reports, enter the following command at the system terminal:

rtrv-trbl:loc=1115:num=1:mode=c

The mode=c parameter provides a continuous output of the trouble reports as they occur. The loc= parameter specifies the active E5-MCAP. The num parameter indicates how many trouble reports you want to display.

A typical trouble report looks similar to this:


tekelecstp 00-05-15  19:04:05 EST EAGLE 35.0.0
   Card 1115 Module tc_utl.c Line 1617 Class 1103 Severity 1
     00 02 f6 00 01 23 06 22 05 00
   Report Date 00-05-15  Time19:04:05

The trouble reports include:

  • Card number

  • Module name

  • Line number

  • Class

  • Severity

3.7 Hourly Status Message Reports

The system provides hourly reports that include a list of all alarms and any devices that are manually deactivated or inhibited. The report contains the alarms that exist at the time the report is generated. Any alarms that have occurred, and have been cleared in the last hour, are not reported. The hourly status message report is automatically generated at the beginning of each hour (08:00, 09:00, and so forth). The system sends the report to all system terminals that can receive unsolicited program update messages.

The information shown in the hourly status report can also be displayed by entering one or more of the following commands.

Note:

Systems supporting an ITU network are not configured with the LNP or SEAS features.
  • rept-stat-alm: Displays the summary of all alarm counts.

  • rept-stat-card: When used with the stat parameter, displays all cards with the state specified by the stat parameter. Refer to Commands User's Guide for additional information on the use of parameters with this command.

  • rept-stat-cdt: Displays the customer defined troubles.

  • rept-stat-clk: Displays the status of the clocks.

  • rept-stat-cluster: Displays the summary status and statistical information for all configured cluster point codes.

  • rept-stat-db: When used with the display=except parameter, displays the status of the system database by displaying the database level of the cards whose database level does not match the active fixed disk current partition. Refer to Commands User's Guide for additional information on the use of parameters with this command.

  • rept-stat-dlk: When used with the :stat parameter, displays the status of the TCP/IP data links. Refer to Commands User's Guide for additional information on the use of parameters with this command.

  • rept-stat-dstn: When used with the stat parameter, displays the destination point codes with the state specified by the stat parameter. Refer to Commands User's Guide for additional information on the use of parameters with this command.

  • rept-stat-dstn: When used with the mode=full parameter, displays the subsystem status. Refer to Commands User's Guide for additional information on the use of parameters with this command.

  • rept-stat-mps: Displays in a single report, the overall status of the EPAP (EAGLE Provisioning Application Processor) subsystem.

  • rept-stat-gpl: Displays the version of the GPL currently being used by an application and which versions of the GPL are the trial and approved versions of that GPL.

  • rept-stat-imt: Displays the primary, secondary, and associated maintenance states of the IMT buses.

  • rept-stat-lnp: Displays the status and statistics related to LNP.

  • rept-stat-sccp: Displays the status of the TSMs running the SCCP application.

  • rept-stat-seas: Displays the status of the SEAS subsystem.

  • rept-stat-slk: When used with the stat parameter, displays the signaling links that have the state specified by the stat parameter. Refer to Commands User's Guide for additional information on the use of parameters with this command.

  • rept-stat-sys: Displays the status of these items: alarms, IMT buses, SS7 signaling links, linksets, destination point codes (DPCs), the maintenance and administration subsystem (MAS), clocks, TSMs loaded with the SCCP or GLS application, security subsystem, and the SEAS subsystem.

  • rept-stat-trbl: Displays a report of all the device trouble notifications that are currently logged in the OAMRAM storage area. The severity of each alarm is also identified in the report.

  • rept-stat-trm: Displays the status of the terminal serial ports.

  • rept-stat-xlist: Displays the statistics related to the storage of exception list (x-list) entries.

If the message reference number (MRN) field has a null value (no field entry), the device has been manually removed from service (through inh-card, canc-slk, and so forth). There is no alarm for the device and the condition type is SCMMA (state change due to manual action). The date and time in the report refer to the date and time of the alarm or when the device was removed from service. The format of the output is in Figure 3-7.

Figure 3-7 Format of Hourly Status Message Output


img/c_hourly_status_message_reports_maintmanual-fig1.jpg

The following is a list of the device types and subsystems (with the ID of the affected device or subsystem) that the hourly status message report displays reports for. For example, if the device type being reported on is CARD, then card locations are displayed. Only those device types and subsystems that have disabled devices or alarm conditions are displayed in the hourly status message report. If there is more than one device type or subsystem to display, they are displayed in the following order.

  1. CARD - the card location

  2. IMT - the IMT bus A or IMT bus B

  3. BITS - the BITS clock

  4. TRM - the terminal port

  5. SLK - the linkset name and the signaling link code (SLC)

  6. DLK - the data links

  7. LS - the linkset name

  8. DPC - the destination point code

  9. CDT - the customer defined trouble number

  10. FUSEPNL - the frame ID of the system

  11. SYSTEM - system

  12. ALM - alarms

  13. SYSCLK - system clock

  14. SYSIMT - system IMT

  15. SCCPSS - SCCP subsystem

  16. GLSSS - GLS subsystem

  17. GPL_SS - the name of the GPL

  18. XLISTSS - XLIST subsystem

  19. SEASSS - SEAS subsystem

  20. SECULOG - Security log

  21. LNPSS - LNP subsystem

  22. LSMS Q.3 Association - Local Services Management System Association

  23. LSMSSS - Local Services Management System subsystem

  25. EMDC Links - Element Measurement & Data Collection Application Links

  26. NDCSS - Network Data Collection subsystem

  27. NDC Q.3 Association - Network Data Collection Q.3 association

  28. GSMSS - GSM subsystem

  29. MPS (ELAP/EPAP) - Multi-Purpose Server

  30. DSM Links - Database Services Module

  31. INPSS - INP subsystem

  32. SECURITYSS - Security subsystem

Within each device type or subsystem being reported, the subsets of the report are displayed in the following order.

  1. Disabled Devices

  2. Minor Alarms

  3. Major Alarms

  4. Critical Alarms

The cond type field supports five values for this release:

  • SCMMA: The device has been disabled due to manual maintenance action. This condition applies regardless of a previous alarm state.

  • MTCEINT-0: The reported device is off normal (ANR), but there is no alarm associated with this device. An alarmed condition for another device typically affects the state of this device. For example, out-of-service (OOS) links affect the condition of the linksets.

  • MAN: The reported device is off-normal (OOS-MT), but there is no alarm associated with this device. The off-normal condition was caused by manual intervention (by entering the ent-dstn command, for example).

  • NULL: No specific cond type is supported. There is sufficient information to ascertain the device condition from the report. You should use a rept-stat command for further information.

  • INAUDB: The use has manually inhibited alarms for this device. The time when the device was inhibited is recorded and displayed during the hourly report.

3.8 Maintenance System Event Logs

The rtrv-log command is used to retrieve records from the active or standby event logs generated by the maintenance system.

3.9 Obituaries

An obituary is a set of data that describes the status of the system just before a processor restarted due to a fault in hardware or software. The data includes a register and stack dump of the processor, card location, reporting module number, software code location, and class of the fault detected. In most situations, obituary reports are generated automatically when a card is reset. Obituary reports can also be retrieved manually using the rtrv-obit command. Refer to Commands User's Guide for information on using the rtrv-obit command. Obituaries should immediately be reported to the My Oracle Support (MOS).

To help My Oracle Support (MOS), retain any printouts of the obituary. My Oracle Support (MOS) can use the report to analyze the problem. A typical obituary looks like the following:

3.12 Modem Not Working

Using Procomm Plus and a modem connected to a serial port on the system, the system can be accessed the remotely. If there are problems connecting to the modem, perform the following procedure:

  1. Check the physical connection.
    The connector to the modem should be an RS-232 connection and firmly seated in both the serial port of the system and the modem.
  2. Verify the flow control is set to software.
  3. Start Procomm Plus and check the modem settings.
    The following are possible modem settings for the recommended modem, the Motorola UDS. (Other types of modems may have different settings):
    • AT&F0 - Load factory profile and defaults
    • AT&C1 - Make DCD true
    • ATE0 - Disable command echo. If you use this command, you do not see the commands that you enter. Be careful to enter the commands correctly.
    • ATQ1 - Stop the results codes to the terminal
    • AT&W0 - Store profile in memory location 0
    • AT&Y - Select stored profile 0 on power up

3.13 Link Maintenance

Link maintenance covers the proper functionality of a signaling link, from an EAGLE MTP card to a remote NE.

Link Fault Sectionalization

The link fault sectionalization (LFS) feature allows maintenance personnel to perform DSOA link fault sectionalization tests, a series of far end loopback tests, from the system and identify faulty segments of an SS7 transmission path up to and including the remote network element.

The point on the signaling link at which each loopback test ends is the far end loopback point. A far end loopback point is achieved when the remote link element sends the received data back to the transmitter, allowing the transmitter to verify the received data. The remote link elements are shown in Table 3-5.

Table 3-5 Remote Link Element types

Element Description Valid for the Latching Link Fault Sectionalization Test? Valid for the Non-latching Link Fault Sectionalization Test?

yes

DSU

DSU Dataport

yes*

yes

NEI

Network Element Interface

yes

no

* The OCU, CSU and DSU must be strapped or optioned to support latching link fault sectionalization loopback.

The loopback point is moved along the signaling link path until the point is in the far end network element. Therefore, each loopback point along the link requires the initiation of one link fault sectionalization test on the SS7LIM.

The link fault sectionalization test types for loopback tests are shown in Table 3-6 .

Table 3-6 Link Fault Sectionalization Test Types

Link Fault Sectionalization Test Types Description

Latching link fault sectionalization test (LLT-auto)

A loopback point is established using signaling commands and remains until it is removed by signaling commands.

Latching link fault sectionalization test (LLT-man)

A loopback point is established by manual means and remains until it is removed by manual means.

Non-latching link fault sectionalization test (NLT)

A loopback command is interleaved with the test data.

The SS7LIM must be powered up and in service with the signaling link deactivated (OOS-MT-DSBLD) before starting the link fault sectionalization tests. No signaling traffic is on the signaling link by the SS7LIM while the link is performing a link fault sectionalization test.

The system supports a maximum of 32 remote link elements for each SS7 link.

The system allows a maximum of 1024 SS7 simultaneous LFS tests.

Hardware Configuration

The link fault sectionalization feature requires a LIM hardware configured as shown in Table 3-8. The test data is guaranteed to be a continuous data stream, and the commands provide the ability to put any element in the link into latched loopback.

The test data is provided is shown in Table 3-7. The data stream sent is verified against the data stream received and a bit error count is updated. If the bit error count is 255 or greater in one second period, the value of the bit error count remains at 255, does not overflow and the test is terminated.

Table 3-7 Link Fault Sectionalization Test Patterns

Test Pattern Data Description

B2047

N/A

2047-bit Bert pattern sent until it is terminated by software.

B2047 Non Latching

N/A

2047-bit Bert pattern sent interleaved with loopback command until it is terminated by software.

B511

N/A

511-bit Bert pattern sent until it is terminated by software.

B511 Non latching

N/A

511-bit Bert pattern sent interleaved with loopback command until it is terminated by software.

OCTET

default =h’32

A continuous series of the specified octet data is sent until it is terminated by software. (Latching only)

ALTERNATE

default = h’FF

A count of 100 octets of the specified data followed by 100 octets of 0 is sent alternating until it is terminated by software. (Latching only)

LFS tests initiated by the EAGLE are used to test the functionality of a signaling link (SLK) from an EAGLEMTP card through multiple channel banks to a remote Network Element. The number of simultaneous tests that can be run on a specific card are shown in parenthesis () in Table 3-8. The maximum number of simultaneous tests for a card is determined by hardware type. Table 3-8 shows the relationship between hardware type and LFS support. A key for the values follows:

  • NV indicates APPL is not valid for the given hardware.

  • No indicates LFS testing is not supported for this combination of hardware, provisioned type, and provisioned application.

  • Yes indicates LFS testing is supported (max tests per card is shown in parenthesis

Test Indicators

Two indicators are used by the rept-stat-slk and rept-stat-ls commands to show whether the signaling link has a far end loopback condition and if a link fault sectionalization test is in progress.

When the signaling link is in a far end loopback condition:

  • The primary state (PST) is OOS-MT-DSBLD.

  • The secondary state (SST) is LPBK .

  • The associate state (AST) is FE .

When a link fault sectionalization test is in progress:

  • The primary state (PST) is OOS-MT-DSBLD.

  • The secondary state (SST) is LPBK .

  • The associate state (AST) is LFS .

When both the signaling link is in a far end loopback condition and a link fault sectionalization test is in progress:

  • The primary state (PST) is OOS-MT-DSBLD.

  • The secondary state (SST) is LPBK .

  • The associate state (AST) is FE-LFS.

Test Report

Test results are displayed to the terminal when the link fault sectionalization tests have completed. The following is an example of a link fault sectionalization test report.

Link Fault Test Commands

The link fault sectionalization feature uses the following commands:

  • ent-lbp — add link fault sectionalization test data to the database.

  • chg-lbp — change existing link fault sectionalization test data in the database.

  • dlt-lbp — remove link fault sectionalization test data from the database.

  • rtrv-lbp — display link fault sectionalization test data in the database.

  • act-lbp — start a link fault sectionalization test.

  • dact-lbp — stop a link fault sectionalization test.

  • rept-stat-lfs — generates a report of all links that are under test.

The link fault sectionalization data is configured in the database using the parameters shown in Table 3-9.

Table 3-9 Link Fault Sectionalization Data Entry Parameters

Link Fault Sectionalization Data Entry Parameters Description

Card Location

SS7LIM card location

Port Number

Port a or b, and a1, a2, a3, b1, b2, b3 on the MPL

Loopback Point Number

Identifies the remote link element for setting the loopback point. Value is from 1 to 32.

CLLI

Description of the remote link element

Remote Link Element Type

The remote element type from Table 3-5.

Repetition Count

A repetition of the same element type in the link path. This is needed for configuring the link element as a latched loopback point. The value is from 0 to 31.

Link Fault Sectionalization Test Type

Link fault sectionalization test type from Table 3-6 (LFS-man not supported for the database)

Use the act-lbp command to start one or a sequence of link fault sectionalization tests. The data stream sent is verified against the data stream received and the bit error counts and block error counts are displayed when the test completes.

The link fault sectionalization test parameters are described in Table 3-7. If either the remote link element type, repetition count, or link fault sectionalization test type are specified with the act-lbp command, they must all be specified and the loopback point number parameter is ignored. Otherwise the values for remote link element type, repetition count, or link fault sectionalization test type are read from the data entered with the ent-lbp command using the loopback point number parameter value. The test data parameter is only valid for test patterns OCTET and ALTERNATE.

If all LBPs are selected for the loopback point number parameter, a sequential test of the LBPs, as entered in the database with the ent-lbp command for that signaling link, is performed until the entire signaling link has been tested. When performing a test with all LBPs, the test is aborted with the first failed test.

The test is stopped either because the amount of time for the test has expired or if the bit error threshold has been exceeded. The time duration parameter specifies the maximum time duration for one link fault sectionalization loopback point test. The default value is one second (00:00:01) and the maximum value that can be entered is 24 hours (24:00:00). The bit error threshold parameter specifies the maximum number of bit errors allowed for one link fault sectionalization loopback point test. The default value is 56 errors and the maximum value that can be entered is 4,838,400 (24 hours x 56 errors per second).

Table 3-10 Link Fault Sectionalization Test Parameters

Parameters Description

Error threshold

Bit error threshold. The value is from 0 to 4838400. The default value is 56.

Test pattern

The test pattern from Table 3-7. The default value is B2047.

Test data

The octet to be used for test pattern OCTET or ALTERNATE only.

The dact-lbp command stops the link fault sectionalization test in progress and cancels any pending link fault sectionalization tests for the SS7 link. The pending tests are the next sequential LBPs for the SS7 signaling link when an entire link test was initiated.

3.13.1 Link Maintenance Enhancements

The Link Maintenance Enhancements feature covers the following areas:

  • Allows the operator to force a card into loopback. Without this enhancement, a card will go in and out of loopback as determined by loopback codes sent by the far end.

  • tst-slk enhancements for ATM customers. The loopback parameters for ATM cards in the tst-slk command act in a similar fashion as the act-lbp command for standard DS0 loopbacks. Other tst-slk enhancements not specifically related to ATM are also provided.

Command Driven Loopback

Command Driven Loopback (CDL) is the ability to locally drive a signaling link into a manual line loopback. The data received on the signaling link is echoed (transmitted) back. Commands are used to provide this capability on an individual signaling link basis. CDL allows loopback testing of a signaling link when either far-end initiated loopbacks are prevented or when a constant loopback state is desired. This command driven setting of loopback is similar in functionality to a remote initiated loopback. Table 3-11 shows a breakdown of support for Command Driven Loopback based on the MTP card type. Figure 3-8 shows a conceptual view of a signaling links network connections. Local transceiver (LXVR) is a tst-slk initiated test in which the line transmit is looped back to the line receive internal to the card. CDL is "LXVR in reverse", the line receive is looped back to the line transmit.

Test Indicators

If an MTP card boots, then all links on this card, by default, are not in CDL. A link in CDL is persistent across an OAM switchover. Signaling links must be inhibited (OOS-MT-DSBLD) to perform command driven loopback. Signaling links in CDL have the following conditions:

  • The primary state (PST) isOOS-MT-DSBLD.

  • The secondary state (SST) is LPBK .

  • The associate state (AST) is CDL .

Test Signaling Link

The tst-slk command is used to flush out intermittent link problems that are not captured with the one shot testing. The tst-slk command allows for duration tests up to 24 hours, stopping of an in-progress test, and forcing the execution of a test. The tst-slk command is grouped into two categories, message based tests and hardware-based tests.

The SLTC and OAM tests are message based. These tests involve sending a message to the far end and expecting an appropriate reply. The LXVR, LINE, and PAYLOAD tests are hardware-based. These tests involve setting hardware registers and after an appropriate duration resetting hardware registers. To prevent overloading of a signaling link, message based tests are delayed 1 to 10 seconds between receipt of an appropriate reply and sending of the next test message. Table 3-12 shows a breakdown of support for each tst-slk test based on MTP card.

Test Signaling Links Test (tst-slk) Indicators

Signaling links performing tst-slk commands have a secondary state of LPBK, and an associated state corresponding to the type of loopback (SLTC, OAM, LXVR, PAYLOAD, LINE). The link must be OOS-MT-DSBLD for LXVR, PAYLOAD, and LINE tests.

If an OAM switchover occurs, while the tst-slk command is running, the test is aborted. If an MTP card with an active test boots then the test is aborted.

Test E1 and T1 Ports

The tst-e1 and tst-t1 commands initiate loopback testing of the specified E1 and T1 ports on the HC MIM and E5-E1T1 cards. There are 8 physical ports on the HC MIM or E5-E1T1 card. This tst-e1/t1 command is not used for any other MTP card type. Table 3-13 shows a breakdown of support for each tst-e1/t1 test based on MTP card.

    Description: This detail sequence is valid for tst-slk:loopback=line and tst-t1:loopback=feline.

    tst-t1:loopback=line installs the local line loopback (receive to transmit) similar to an act-cdl:loopback=line.

    The following steps occur:

    1. Device under test (DUT) sends T1 bit oriented code (BOC) to remote device.

    2. Remote device receives BOC and programs hardware.

    3. DUT attempts level 2 alignment.

    4. If link aligns (level 2), test passes, else test fails.

    5. DUT sends BOC to remote device to remove loopback.

    6. Remote device receives BOC and re-programs hardware.

      Note:

      If the DUT boots in the middle of the sequence, the remote device needs to have the link activated/de-activated and it will return to the original programming.

Link Maintenance Enhancements Commands

The link maintenance enhancements feature utilizes the following commands:

  • act-cdl — this command initiates a command driven loopback for testing a signaling link.

  • dact-cdl — this command deactivates a previously initiated Command Driven Loopback if active. If not, it will attempt to clear both near-end and far-end latched loopback points.

  • rept-stat-cdl — this command generates a report of the signaling links currently in command driven loopback (along with the amount of time the link has been in CDL). The following is an example of a possible output.

3.14 Power Down of In-Service System

warning:

This procedure will isolate the system and put the network in a degraded mode. My Oracle Support (MOS) before any part of this procedure is performed.

Note:

If the EAGLE loses power or both OAM cards are removed at the same time, then OAM may not retain the current date and time once the MASP cards are back in service. The user may need to manually update the system date and time using set-date & set-time commands.

To minimize the impact on the rest of the network during power up, proper network planning must be performed. This requires having the MTP Restart Feature configured on the system. This power down procedure does not require any special configuration on the system. This procedure should be performed in emergency situations or with prior planning assistance from My Oracle Support (MOS). Terminal access to the system is required to deactivate the links.

3.15 Power Up of the System

warning:

If the reason for the EAGLE Power Off is unknown or if damage to the EAGLE is suspected, do not perform this procedure. contact the My Oracle Support (MOS).
  1. Verify that there is no USB drive in the E5-MDAL card.
    If there is a USB drive in the E5-MDAL, replace the E5-MDAL card with a spare E5-MDAL card without a USB drive. If the spare E5-MDAL card has a USB drive installed, remove the E5-MDAL card. This power up will take place without a E5-MDAL card installed.
  2. At the power distribution frame, insert fuses or close the breaker to restore power to the system.
    All frames with the EAGLE shelves must be powered up. Links that were deactivated during the power down are automatically activated during the power up.
  3. Enter the following commands to monitor the system during the power-up:
    rept-stat-card
    rept-stat-slk
    rept-stat-trbl
    Contact My Oracle Support (MOS) if there is any trouble or abnormal condition during system recovery.
  4. Install E5-MDAL card and remove removable USB drive, if necessary.
