B Backplane Connectors
B.1 Control Shelf Connectors
This section describes the Control shelf backplanes and their connectors. The control shelf backplane provides connectors for the system circuit cards. These connectors are four column High Density Interconnect (HDI) male headers with shrouds of varying pin quantities, depending on card position.
The control shelf backplane provides –48VDC power and ground to all card positions. The power is distributed into two parts, A and B. Power is brought to the shelf from the Fuse and Alarm Panel (FAP) using two cables. The connectors on the control shelf backplane are DB-26 high density connectors. The power is distributed over two separate pins per power connection to handle the current load.

B.1.8 BITS Clock Connectors
The system connects to the Building Integrated Timing System (BITS) clocks using two DB-15 style connectors. The two clocks are labeled Primary and Secondary and are supplied from the central office clock. Both clocks go to both TDMs, where one is selected to provide the system clocks used to provide system timing.

B.1.9 Serial Port Connectors
The control shelf backplane provides an interface for 16 separate serial port connections from the TDMs. These connections provide RS-232 interfaces for terminals, printers, and modems. The system is set up as Data Terminal Equipment (DTE).

B.2 Extension Shelf
The extension shelf backplane provides connectors for 18 circuit cards. These connectors are four column High Density Interconnect (HDI) male headers with shrouds of varying pin quantities depending on card position. The reverse or component side of the backplane contains DB style connectors for interfacing to the rest of the system.

B.2.2 Power Connectors
The extension shelf backplane provides –48VDC power and return to all card positions. The power is divided into parts A and B and brought to the shelf from the Fuse and Alarm Panel (FAP) using two cables. The power connectors on the extension shelf backplane are DB-26 high density connectors with two pins per power connection to handle the current load.
