CIC Mapping
CIC mapping is assigning Circuit Identification Codes to specific spans and chans. The concept of Channel Numbering is intimately related.
Here is a possible CIC map for a 2 E1 system:
This mapping comes from information supplied by the telco. They may provide an identifer for each E1 loop and the CICs assigned to each loop. We must then ensure that the:
It is possible that the telco could specify the same CIC map as follows: E1-1 CIC 00..31 E1-2 CIC 32..63 SS7 link T/S 16 on E1-1 In this case we modify the range to omit E1 sync channel 0 as follows: E1-1 CIC 01..31 E1-2 CIC 33..63 Then we omit the SS7 channel as follows: E1-1 CIC 01..15, 17..31 E1-2 CIC 33..63 The ss7boost.conf [TRUNK] section reflects this configuration.
