Configuring E1 Interfaces; Configuring Drop And Insert - Cisco MWR 1941-DC - 1941 Mobile Wireless Router Software Configuration Manual

Configuring T1 and E1 Interfaces

Configuring E1 Interfaces

To configure a new T1 interface (or change an existing one), complete the following tasks beginning in
global configuration mode:
Command
Step 1
Router(config)# controller e1 1/0
Step 2
Router(config-controller)# framing crc4
Step 3
Router(config-controller)# linecode hdb3
Step 4
Router(config-controller)# channel-group 0
timeslots 1,3-5,7
Step 5
Router(config-controller)# interface serial
1/0:0
Step 6
Router(config-if)# ip address 10.1.15.1
255.255.255.0
Step 7
Router(config-if)# exit
Step 8
Router(config-if)# Ctrl-z

Configuring Drop and Insert

The Drop and Insert feature can be configured using the Cisco VWIC-2MFT-T1-DIR and
VWIC-2MFT-E1-DIR VWICs.
Drop-and-Insert capabilities allow individual 64Kb DS0 channels to be transparently passed,
uncompressed, between two ports on the same VWIC without passing through a digital signal processor
(DSP).
Note T1/E1 channels can be used either for Drop and Insert or VoIP, but not both.

Purpose
Select the CE1/PRI interface to configure. This
example configures an E1 interface in slot 1 and
unit 0.
Specify the framing type.
Specify the line code format.
Specify the channel group and time slots to be
mapped. For multiflex trunk interfaces, only
channel 0 can be configured.
Configure each channel group as a virtual serial
interface. Specify the E1 interface, unit number,
and channel group to modify.
Assign an IP address and subnet mask to the
interface.
Exit back to global configuration mode.
Return to Step 4 if your router has more than one
CE1/PRI interface that you need to configure.
When you finish configuring interfaces, return to
enable mode.
