Making the Service Interface Connections
The customer data is connected to the MGX 8220 shelf through T1, E1, X.21, or HHSI lines.
Service lines using DB15 and RJ-48 connectors need only one cable per port. Service lines using BNC
or SMB connectors require two cables (one transmit and one receive) from the E1 port of the customer
equipment to on E1 port on an MGX 8220 line module.
