DID-DS1 WARNING
1. A Major alarm on a trunk indicates that alarms on these trunks are not downgraded by the set options
command and that at least 75 percent of the trunks in this trunk group are alarmed. For more information, see
the set options command.
The DID-DS1 trunk provides a digital Direct Inward Dial (DID) trunk from a CO
switch to the system through a DS1 link. A 24-channel DS1 link can support up to
24 DID-DS1 trunk calls simultaneously. A 32-channel link can support up to 30. A
DID-DS1 trunk can be used for digitized voice and data communications with
appropriate DS1 signaling mode (for example, common-channel signaling). The
TN767 and TN464 series circuit packs support wink-start and immediate-start
trunks and Avaya MultiVantage ™ software signaling. See
