For systems supporting circuit packs:
If ATMS testing is enabled, check the error log for ATMS errors 3840 and 3841. If the error log
indicates that measurements exceeded acceptable thresholds, and no other trouble is found
with test trunk, run the ATMS test call with test analog-testcall port location
full.
Note:
Note: Many trunk problems are caused by incorrect settings of parameters on the trunk
group administration screen. Settings must be compatible with the local
environment and with parameter settings on the far end.
Analog CO trunks are 2-wire analog lines to the CO that support both incoming and outgoing
calls. CO trunk circuit packs have eight ports, each of which provides an interface between the
2-wire CO line and the 4-wire TDM bus. The system supports the following CO trunk circuit
packs:
