Return to Step 1 to configure the second port on the VWIC and the ports on any additional VWICs.

Configuring E1 Interfaces

To configure the E1 interfaces, use the following commands, beginning in global configuration mode:
Command
Step 1
Router(config)# controller e1 slot/port
Step 2
Router(config-controller)# framing crc4
Step 3
Router(config-controller)# linecode hdb3
Step 4
Router(config-controller)# channel-group 0 timeslots
1-24 speed 64

Cisco MWR 1941-DC Router with the Cisco IOS IP-RAN Feature Set
Purpose
Assigns an IP address and subnet mask to the
interface. If the interface is a member of a Multilink
bundle (MLPPP), then skip this step.
Configures PPP encapsulation.
Note Before you can enable RTP header
compression, you must have configured a
serial line that uses PPP encapsulation.
Enables keepalive packets on the interface and
specify the number of times keepalive packets will be
sent without a response before bringing down the
interface.
When enabled in an IP-RAN solution, the
Note
recommended configuration is keepalive 1 2
on both the MWR 1941-DC serial interface
and associated MGX-RPM-1FE-CP virtual
template interface.
Sets the carrier delay for the serial interface.
Exits to global configuration mode.
Purpose
Specifies the controller that you want to configure.
Controller E1 0/0 maps to the first port of the VWIC
in slot 0. Controller E1 0/1 maps to the second port of
the VWIC in slot 0.
Specifies the framing type.
Specifies the line code format.
Specifies the channel group and time slots to be
mapped.
For the VWIC interfaces, you can configure
channel-group 0 and 1 on one port or one
channel-group (either 0 or 1) on each port. Once you
configure a channel group, the serial interface is
automatically created.
The default speed of the channel group is 56.
Note
To get full DS0/DS1 bandwidth, you must
configure a speed of 64.
