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 ).
