Configuring the PA-2CE1 Interfaces
Note
Router(config-controller)# interface serial 3/1/1:15
Router(config-if)# ip address 10.1.15.1 255.255.255.0
Router(config-if)#
Add any additional configuration commands required to enable routing protocols and adjust the interface
Step 8
characteristics.
Use the no shutdown and exit commands respectively to reenable the interface and return to
Step 9
configuration mode as follows:
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:15,
changed state to up
%LINK-3-UPDOWN: Interface Serial3/1/1:15, changed state to up
Step 10
After configuring the PRI group and timeslots, map all unused timeslots to an unused channel group and
shut down the unused channel group by entering the channel-group and shutdown commands,
respectively.
Note
Both PA-2CE1 interfaces support simultaneous operation in channelized E1 and ISDN PRI
modes.
In the following example, unused timeslots 2, 6, 8 through 15, and 17 through 31 are mapped to unused
channel group 2, and channel group 2 is shut down:
Router(config)# controller e1 3/1/1
Router(config-controller)# channel-group 2 timeslots 2,6,8-15,17-31
Router(config-controller)#
Router(config-controller)# interface serial 3/1/1:2
Router(config-if)# shutdown
Router(config-if)# exit
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:2,
changed state to down
%LINEPROTO-5-UPDOWN: Interface Serial3/1/1:2, changed state to
administratively down
After including all of the configuration commands, to complete the configuration, press Ctrl-Z (hold
Step 11
down the Control key while you press Z) or enter end to exit configuration mode and return to the EXEC
command interpreter prompt as follows:
Router(config)#
Ctrl-Z
Router#
Write the new configuration to memory as follows:
Step 12
Router# copy running-config startup-config
[OK]
Router#
Step 13
The system displays an OK message when the configuration is stored.

For channelized E1 ISDN PRI, the PRI group is configured by using timeslot 16,
which is recognized by the system as timeslot 15.
