2.8.5 Setting the Remote Loopback Switch

At the factory, V/S24T1 and V/S30E1 boards have the remote loopback switch set to
normal mode (default). Once installed, McIAS 16xx/IP T1 and E1 connections may be
tested by setting the switch to loopback mode as illustrated below. In loopback mode,
if the LED lights red then T1 or E1 connections to the switch are operating properly.
