Running Loopback Tests

ASMi-52 supports the local and remote loopbacks as per ITU V.54, by using the following methods:

•From the supervisory terminal.

•Via corresponding pins of the synchronous interface, for the ASMi-52 with V.35 interface and RS-530 interfaces only.

Loopback in Multiplexer Units

Figure 6-20 is an illustration of how loopback works in the local ASMi-52.
