Connecting to the CMS Network Management System
The Excalibur Multirate DAP provides a 10-pin jack labeled NMI for connecting to the
CMS network management system. Use Cable Part No. 5956-158V which has a 10-pin
plug at one end and a 6-pin plug at the other end to make this connection. When
connecting to tail circuit equipment, use the following cables:
• When connecting a remote site Excalibur Multirate DAP to a tail circuit modem
that has a SJ18 connector (such as an Omnimode), use Cable Part No. 5956-
