SS7 CIC Traffic Over the DS3 Line Card
Overview
The DS3 line cards support SS7 CIC traffic. Under normal operation, a DS3 line card can handle 28 spans, and an CSP chassis can support up to three DS3 line cards. If you wish to support SS7 CIC traffic on all three line cards, you must reconfigure one of the DS3 line cards to 24 spans using DIP Switch 4 and 6. The table below shows what the DIP switch settings are.
