Physical Interface Configurations (T1, E1, and Ethernet) T1/E1 WAN Configuration Guide

The following example commands specify the configuration parameters required for a standard T1

interface:

>enable

#config terminal

(config)#interface t1 1/1

(config-t1 1/1)#tdm-group 1 timeslots 1-24

(config-t1 1/1)#no shutdown

(config-t1 1/1)#exit

Configuring E1 Interfaces

There are four main settings to consider when configuring E1 network interfaces. The line coding

(coding), framing format (framing), active channels (tdm-group), and clock source (clock source) must

all be configured to match the circuit supplied by your network provider. By default, all NetVanta E1

interfaces are configured for standard multi-frame without the optional CRC4 error correction (no framing

crc4), and to recover clocking from the network circuit (clock source line). Generally, the line coding,

framing format, and clock source default values will be the correct ones for your application and should

not be changed.

Each configured E1 interface must have the active channels specified using the tdm-group command

because there are no default TDM groups. The active channels are entered as a single number representing

1 of the 31 E1 channel timeslots or as a contiguous group of channels.

The following example commands specify the configuration parameters required for a standard E1

interface:

>enable

#config terminal

(config)#interface e1 1/1

(config-e1 1/1)#tdm-group 1 timeslots 1-31

(config-e1 1/1)#no shutdown

(config-e1 1/1)#exit
