DID Trunks (Figure 3-10)

Direct Inward Dialing trunks must be bridged from the telco RJ21X to a line cross-connect (A) block. Each DID
Trunk requires one-pair cross-connect from the RJ21X to the line (A) block.
The A block connects to the DID blade and an RJ-61 jack. The line (A) block should be arranged in groups of 4
DID trunks (8 pins) or 8 DID trunks (16 pins) to correspond with the chassis slot equipped with a DIOPU blade.
