Chapter 3 Configuring with the Command-Line Interface
Configuring T1/E1 Interfaces
Step 5
clock source line
Example:
Router(config-controller)# clock source line
Specifies which end of the circuit provides clocking. The
clock source should be set to use internal clocking only
for testing the network or if the full T1/E1 line is used as
the channel group. Only one end of the T1/E1 line should
be set to internal.
Step 6
framing T1/E1 controller
Example:
Router(config-controller)# framing esf
Specifies the framing type for T1.
Step 7
framing T1/E1 controller
Example:
Router(config-controller)# framing crc-4
Specifies the framing type for E1.
Step 8
linecode {ami|b8zs|hdb3}
Example:
Router(config-controller)# linecode b8zs
Specifies the line code format for E1 and the linecode
format for T1.
Step 9
linecode {ami|b8zs|hdb3}
Example:
Router(config-controller)# linecode hdb3
Specifies the line code format for E1 and the linecode
format for T1.
Step 10
channel-group
channel-group-number
timeslots
range
Example:
Router(config-controller)# channel-group 0
timeslots 1,3-5,7
Specifies the channel group and time slots to be mapped.
For multiflex trunk interfaces, only channel 0 can be
configured.
Note
Channel-group number should be different from
DS0-group number and TDM-group number
under the same controller.
Step 11
interface
type number
Example:
Router(config-controller)#
interface serial 1/0:0
Configures each channel group as a virtual serial
interface. Specifies the T1/E1 interface, the unit number,
and the channel group to modify.
Step 12
ip address
ip address subnet mask
Example:
Router(config-if)# ip address 10.1.15.1
255.255.255.0
Assigns an IP address and subnet mask to the interface.
Step 13
exit
Example:
Router(config-if)# exit
Exits to global configuration mode.
Step 14
Ctrl-z
Example:
Router#
Returns to enable mode when you finish configuring
interfaces.
