5.3 Standalone Modem Diagnostic Tools
The 2361 rackmount modem has no panel switches for loopbacks. All loopback tests are
controlled via software. The standalone modem, however, does have a limited set of hardware-
controlled loopbacks that are on the front panel. On the front of the 2361 standalone modem, near
the right center, note the switch labeled loopback. It has three positions, Local, Off, and Remote.
Loc: Sets a loopback test on the local modem
Off: Loopback tests are off
Rem: Sets a loopback on the remote modem
The 2361 standalone modem also provides the same set of software-controlled loopback tests
available on the rackmount modem.
