Configuring the Interfaces
This example configures an E1 line:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router)#
controller T3 4/1
Router(config-controller)#
channelized mode e1
Router(config-controller)#
e1 10 channel-group 0 timeslots 1-5, 20-23
Router(config-controller)#
e1 10 framing crc4
Router(config-controller)#
e1 10 national bits
Router(config-controller)#
e1 10 clock source line
Router(config-controller)#
e1 10 loopback network line
Router(config-controller)#
e1 10 bert pattern 2^23 interval 5 unframed
Router (config-controller)#
exit
Router(config)#
interface serial e1 4/0/10:0
Router(config-if)#
CNTL/Z
Router#
Configuring Distributed MLPPP
Distributed MLPPP allows you to combine T1 or E1 lines into a bundle that has the combined bandwidth
of multiple T1 or E1 lines. Bundling T1 or E1 lines enables you to increase the bandwidth of your
network links beyond that of a single T1 or E1 line without having to purchase a T3 line.
