Zhone Technologies 4000E Interface Module a Interface Module B Connectors

1Identify the appropriate RJ21 Connector. Subscriber lines must be connected according to the 4000E slot in which the corresponding interface module was installed. Interface module slots 1–4 run from bottom to top; the corresponding RJ21 ports are directly behind each slot on the back of the chassis (1–4, bottom to top). Each interface module slot on the 4000E has two corresponding RJ21 connectors on the back of the chassis: the RJ21 connectors on the left (A) provide the subscriber connections for interface module ports 1–24 (on most models) and the RJ21 connectors on the right (B) provide the subscriber connections for interface module ports 25–48 (on applicable models). For the TIM1500-24 and EIM2000-24 interface modules, the A connectors provide the subcriber connections for ports 1-12 and the B connectors provide the subscriber connections for ports 13-24.
