INSTALLING DID TRUNKS
3.9.1
DID Trunks
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.
Installing DID Trunks
1.
Punch down one pair cross-connect to the tip and ring leads for each DID trunk on the CPE (customer)
side of the RJ21X.
2.
Punch down the other end of the cross-connect to the line (A) block tip and ring leads.
3.
Punch down a 25-pair cable to the opposite side of the line (A) block.
4.
Plug in the corresponding RJ-61 connector to the DID blade connector.
5.
Install bridging clips on the A block.
