A CompactPCI line interface board providing 16 T1/E1/J1 ports (provided by a
companion Rear Transition Module).
The number of signaling processors supported on each board determines the maximum
number of links that can be supported. The signaling processor CPU controls Message
Transfer Part 2 (MTP2) protocol operation of the board. Each board also contains a
main CPU that handles the board management and monitoring functions.
For the CompactPCI boards, the rear transition modules that are available are:
• SS7HDCR8TEW
SS7 CompactPCI Rear Transition Module with 8 T1/E1/J1 ports
• SS7HDCR16TEW
SS7 CompactPCI Rear Transition Module with 16 T1/E1/J1 ports
All CompactPCI boards interoperate with all rear transition modules. See Section 2.3.4,
“Rear Transition Modules” on page 18 for more information.
