Connectors

The OSS-wanPCI-CxT1E1 supports four T1/E1/J1 ports. Four PM4351 COMET chip sets provide the framer and LIU to support the

four T1/E1/J1 ports. The CSU components reside on the OSS-wanPCI-CxT1E1. The tip and ring for each port are routed to the

individual fully shielded RJ48C connector mounted to the PMC bezel.
