Chapter 7 Configuring the Channelized 12-port CT3/T1 Optical Services Modules
Configuring the Interfaces
This example shows how to configure the controller:
Router#
configure terminal
Router(config)#
controller
T3 3/0
Router(config-controller)#
no
channelized
Router(config-controller)#
exit
Router(config)#
Configuring the Unchannelized DS3 Interface
After you verify the controller configuration, you can configure the associated DS3 interfaces.
Command
Purpose
Step 1
Router#
configure terminal
Enters configuration mode and specifies that the
console terminal is the source of the configuration
subcommands.
Step 2
Router(config)#
controller t3
slot/port
Selects a port and enters controller configuration
mode.
Step 3
Router(config-controller)# [
no
]
channelized
[
mode
{
t1
|
e1
}]
Specifies the channelization mode.
no channelized
—configures the interface as
unchannelized.
channelized mode t1
—configures the interfaces
for T1 channelized mode
channelized mode e1
—configures the interfaces
for E1 channelized mode
Default is
t1
.
Step 4
Router(config-controller)# [
no
]

interval
[
1-1440
]
(Optional) Configures bit-error-rate (BER)
testing.
Step 5
Router(config-controller)# [
no
]
mdl string
{
eic
|
fic
|
generator
|
lic
|
pfi
|
port
|
uni
t}
(Optional) Specifies the maintenance data link
(MDL) messages.
eic
—equipment ID code
fic
—frame ID code
generator
—generator number in MDL test signal
lic
—location ID code
pfi
—facility ID code in MDL path message
port
—port number in MDL idle string message
unit
—unit code
Default is
no mdl string
.
Step 6
Router(config-controller)# [
no
]
mdl transmit
{
path
|
idle-signal
|
test-signal
}
(Optional) Enables MDL message transmission.
Default is
no mdl transmit
.
Step 7
Router(config-controller)#
t1 1 bert channel-group 0
pattern 2^11 interval 1
(Optional) Configures bit error rate testing on
channel-group 0 (all timeslots under channel
group 0).
Step 8
Router(config-controller)#
t1 1 bert timeslots 21,24
pattern 2^11 interval 1
(Optional) Configures bit error rate testing on
timeslots 21 and 24 only.
