Trunk Termination
This section describes the status and control commands for trunk terminations. Either a range (for
example, cic=1-24;) or a single value (for example, cic=1;) for the CIC parameter can be specified for
the status and control of trunk terminations.
Individual trunks and trunking groups can be placed into any of three administrative service states: INS,
OOS, and MAINT. The relationship between trunk/trunk group state and the TGW state is provided in
Table 3-5. For all other trunk types, the trunk state and trunk group state are independent.
where:
• TGW—trunking gateway
• TG—trunk group
• OOS—out of service
• MAINT—maintenance
• INS—in service
• UEQP—unequipped
The rules for placing trunks and TG into the OOS, INS, and MAINT states (which depend upon the TGW
state) are shown in Figure 3-3.
