Troubleshooting: SCCP Backplane

PRELIMINARY
Introduction
The SCCP Backplane is a multi–layer printed circuit board that
interconnects all of the SCCP Cards and Modules. The complexity of
this board lends itself to possible improper diagnoses when problems
occur.
Connector Functionality
The following Connector Overview describes the major types of
Backplane Connectors along with the functionality of each. This will
assist the CFE to:
S Determine which connector(s) is associated with a specific problem
type.
S Isolate problems to a specific cable or connector.
Span Line Connector
The 50–pin Span Line Connector provides a primary and secondary (if
used) Span Line Interface to each GLI in the SCCP Cage. The Span Line
is used for MM/EMX Switch Control of the Master GLI and also all of
the BBX Traffic.
Power Input (Return A and B Connectors)
Provides 27 Volt Input for use by the Power Supply Modules.
Power Supply Module Interface
Each Power Supply Module has a series of three different connectors to
provide the needed inputs/outputs to the SCCP Backplane. These are:
– VCC/Ground Input Connector
– Harting–style Multiple Pin Interface
– +15V Analog Ground Output Connector
The Transceiver Power Module converts 27 Volts to a regulated +15,
+6.5, +5.0 Volts to be used by the SCCP Cage Cards.
GLI Connector
This connector consists of a Harting 4SU Digital Connector and a
6–conductor COAXial Connector for RDM Distribution. The connectors
provide inputs/outputs for the GLI Cards in the SCCP Backplane.
GLI Ethernet “A” and “B” Connections
These SMB Connectors are located on the SCCP Backplane and connect
to the GLI Card. This interface provides all the Control and Data
Communications over the Ethernet LAN between the Master GLI, the
Redundant GLI, and the LMF.
BBX Connector
Each BBX Connector consists of a Harting 2SU/1SU Digital Connector
and two 6–conductor COAXial Connectors. These connectors provide
DC, Digital, and RF Inputs/Outputs for the BBX Cards in the SCCP
Backplane.
