4.3 Diagnostic Tests

Maintenance capabilities include external and internal loopbacks.

E1/T1

External Loop

IPmux-1 can be set to an external loop to test the connection between the E1/T1 port and the PBX (refer to Chapter 3). In this mode, data coming from the PBX is both looped back to the PBX and transmitted forward to the IP network (see Figure 4-1).

This mode can also be achieved by a T1 FDL line loopback command.
