Switch SW2-4: Remote Digital Loopback Type

The user can set this switch to select the type of remote loop that will be initiated by the Model 2701. If set to V.54, the Model 2701 will initiate a V.54 loop when Remote Loop is selected by the front panel switches. If set to CSU, the Model 2701 will initiate a CSU loop when Remote Loop is selected by the front panel switches.

S2-4	RDL Type
Off	Initiate a V.54 RDL loop when selected
On	Initiate a CSU loopback when selected

Switch SW2-5 Front Panel Switches

As the Front Panel Switches may be inadvertently toggled, or in the event that the end-user may not need to use the switches, the installer may disable the front panel switches. Set Switch S2-5 to determine whether the front-panel toggle switches are active or inactive.

SW2-5	Option
Off	Front Panel Switches Enabled
On	Front Panel Switches Disabled

Switch SW2-6: V.54 Response Disabled (default)

V.54 Response is a special in-band loopback facility that sends a pseudo-random pattern over the data stream. This is the only loopback that the unit can initiate. This is useful for campus applications when you need to put a remote unit in loopback. The unit responds to the V.54 loop- back command, and the whole process takes only a few seconds to com- plete. When V.54 Loopback is disabled, the unit will not be able to send or respond to V.54 loopback commands. The duration of the loopback is limited by the loopback timeout setting.

SW2-6		Option
Off	V.54	Response Enabled
On	V.54	Response Disabled
