Configuring E1 and T1 Interfaces
Quick Start
4-40
5. Move to the E1 or T1 interface configuration mode context.
Syntax: interface <interface> <slot>/<port>
For example, if you are configuring a one-port E1 or T1 module that is
installed in slot one, enter:
ProCurve(config)# interface e1 1/1
or
ProCurve(config)# interface t1 1/1
You can also specify a range of interfaces to configure.
Syntax: interface range [e1 | t1] [<slot/port-port> | <slot/port>, <slot/port>]
For example, to specify several E1 ports for configuration, enter:
ProCurve(config)# interface range e1 3/1-2, 3/4-6, 3/8
6. Create a TDM group and assign it the number of channels used for this
connection.
Syntax: tdm-group <number> timeslots <range of numbers>
For example, to assign the E1 or T1 interface all the available channels,
enter:
ProCurve(config-e1 1/1)# tdm-group 1 timeslots 1-31
or
ProCurve(config-t1 1/1)# tdm-group 1 timeslots 1-24
7. Configure the line coding. For E1 interfaces, use the following syntax:
Syntax: coding [ami | hdb3]
ProCurve(config-e1 1/1)# coding ami
HDB3 is the default setting for E1 interfaces.
For T1 interfaces, use the following syntax:
Syntax: coding [ami | b8zs]
ProCurve(config-t1 1/1)# coding ami
B8ZS is the default setting for T1 interfaces.
