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.
