Configuring Serial Interfaces IC-125
Enable Loopback Line Examples
The following example shows how to configure a payload loopback:
Router1# loopback line payload
Loopback in progress
Router1# no loopback line
The following example shows the output when you loop a packet in switched mode without an active
connection:
Router1# service-module 56k network-type switched
Router1# loopback line payload
Need active connection for this type of loopback
% Service module configuration command failed: WRONG FORMAT.
Loopback DTE Example
The following example loops a packet from a module to the serial interface:
Router1# loopback dte
Loopback in progress
Router1# ping 12.0.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.0.0.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/12/28 ms
Setting the Clock Source Example
The following example shows a router using internal clocking while transmitting frames at
38.4 kbps:
Router1# service-module 56k clock source internal
Router1# service-module 56k clock rate 38.4
TI CSU WIC Configuration Example
The following example shows how to set the fdl parameter to att while in interface configuration
mode:
panther2(config-if)#service-module t1 fdl att
Exit
CTRL-Z.
