The T1 Network Interface is used to connect the CSMIM-T1 to the T1
line. The T1 Network Interface port is located on the front panel of the
CSMIM-T1.
To connect to the T-1 network, simply plug the RJ48C connector located
on the T1 Network Interface Cable into the T1 Network Interface port
located on the front panel of the CSMIM-T1.
When the connector clicks into place, the connection is secure. Appendix

state.
