DID-TRK (DID Trunk)
Direct Inward Dial (DID) trunks coming from the Central Office (CO) allow outside
parties to call directly to an extension in the system. DID Trunk circuit packs
include:
The DID Trunk circuit packs support eight, incoming-only, ports. Each port
provides an interface between the 2-wire analog line from the CO and the
DEFINITY system. The DID port receives 3 to 5 digits from the CO that is used to
directly connect an outside caller to the called station without assistance from an
attendant. See Figure 3-16
