Enabling the Interfaces on the Controller
To create the interfaces for the 8-Port Channelized T1/E1 Serial SPA, complete these steps:
SUMMARY STEPS
1.
Router(config)#
controller
{
t1
|
e1
}
slot
/
subslot
/
port
2.
Router(config-controller)# clock source {internal | line}
3.
Router(config-controller)# linecode {ami | b8zs | hdb3}
4.
For T1 controllers
5.
Router(config-controller)# channel-group t1 t1-number {timeslots range | unframed} [speed {56 | 64}]
6.
Router(config)#
exit
DETAILED STEPS
Purpose
Command or Action
Selects the controller to configure and enters controller configuration mode.
Router(config)#
controller
{
t1
|
e1
}
slot
/
subslot
/
port
Step 1
•
t1
—
Specifies the T1 controller.
•
e1
—
Specifies the E1 controller.
•
slot/subslot/port
—
Specifies the location of the interface. See the
Interface Address on a SPA, on page 228
.
Sets the clock source.
Router(config-controller)# clock
source {internal | line}
Step 2
The clock source is set to internal if the opposite end of the connection is set
to line and the clock source is set to line if the opposite end of the connection
is set to internal.
Note
•
internal
—
Specifies that the internal clock source is used.
•
line
—
Specifies that the network clock source is used. This is the default for T1
and E1.
Selects the linecode type.
Router(config-controller)#
linecode {ami | b8zs | hdb3}
Step 3
•
ami
—
Specifies Alternate Mark Inversion (AMI) as the linecode type. Valid for
T1 and E1 controllers.
After configuring the linecode as Alternate Mark Inversion (AMI), you need
to configure invert-data by executing the invert-data command from interface
configuration mode.
Note
•
b8zs
—
Specifies binary 8-zero substitution (B8ZS) as the linecode type. Valid
for T1 controller only. This is the default for T1 lines.
•
hdb3
—
Specifies high-density binary 3 (HDB3) as the linecode type. Valid for
E1 controller only. This is the default for E1 lines.
