Configuring T1 Interfaces
There are four main settings to consider when configuring T1 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 Secure Router T1
interfaces are configured for ESF (framing esf) and B8ZS (coding b8zs), 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 T1 interface must have the active channels specified using the tdm-group command
because there are no default TDM groups defined. The active channels are entered as a single number
representing 1 of the 24 T1 channel timeslots or as a contiguous group of channels.
The following example commands specify the configuration parameters required for a standard T1
interface:
ProCurve>enable
ProCurve#config terminal
ProCurve(config)#interface t1 1/1
ProCurve(config-t1 1/1)#tdm-group 1 timeslots 1-24
ProCurve(config-t1 1/1)#no shutdown
ProCurve(config-t1 1/1)#exit
The following example specifies the configuration parameters required for a standard T1 interface using
