Testing IPmux-11, Running Loopbacks

Installation and Operation Manual		Chapter 6 Troubleshooting and Diagnostics

6.5 Testing IPmux-11

Diagnostic capabilities of IPmux-11 include:

•External loopbacks

•Inband remote loopbacks for T1 lines

•Internal loopbacks

•Pinging IP hosts

•Running a trace route.

Running Loopbacks

Running External Loopback

IPmux-11 can be set to start an external loopback to test the connection between the E1/T1 port and the PBX. In this mode, data coming from the PBX is both looped back to the PBX and transmitted forward to the IP network

(see Figure 6-10).

Figure 6-10. External Loopback

Running Internal Loopback

The E1/T1 module can be set to start an internal loopback to test the connection between the E1/T1 port and the IP network. In this mode, data coming from the IP network is both looped back to the IP network and transmitted forward to the PBX connected to the E1/T1 port (see Figure 6-11).
