Modular ICS 7.1 Installer Guide
The Modular ICS supplies the NT1 functionality to a U-NT
loop, allowing a direct connection to the network. The
connection may use a plug and jack, or may be directly wired.

The BRI-U Card does not use or provide optional power.
Some installations may not use a plug and jack for connections between the ICS (NT) and the network.
