Enable

Acceptance of a

Remote

Loopback

Request

In interface configuration mode, enable the acceptance of a remot loopback request on a 2- or 4-wire 56/64-kbps CSU/DSU module:

service-module 56k remote-loopback

The no service-module 56k remote-loopback command prevents the local CSU/DSU from being placed into loopback by re- mote devices on the line. Unlike the T1 module, the 2- or 4-wire 56/ 64-kbps CSU/DSU module can still initiate remote loopbacks with the no form of this command.

Select a Service Provider

In interface configuration mode, select a service provider to use with a 2- or 4-wire 56/64 kbps dial-up line:

service-module 56k switched-carrier {att other sprint}

The att keyword specifies AT&T or another digital network service provider as the line carrier, which is the default for the 4-wire 56/64 kbps CSU/DSU module. Th sprint keyword specifies Sprint or an- other service provider whose network carries mixed voice and data as the line carrier, which is the default for the 2-wire switched 56-kbps CSU/DSU module.

In a Sprint network, echo-canceler tones are sent during call setup to prevent echo cancelers from damaging digital data. The transmission of these cancelers may increase call setup times by 8 seconds on the 4- wire module. Having echo cancellation enabled does not affect dat traffic.

This configuration command is ignored if the network type is DDS.

Use the no form of this command to enable the default service pro- vider. AT&T is enabled by default on the 4-wire 56/64 module. Sprint is enabled by default on the 2-wire switched 56 module.
