Chapter 7 Configuring the Channelized 12-port CT3/T1 Optical Services Modules
Configuring the Interfaces
Configuring the Channelized DS3 Interface
The DS3 Interface can be channelized down to T1 and E1 links. These sections provide configuration
information for T1 and E1 link configuration:
•
Configuring the T3 Controller for Channelization, page 7-9
•
Configuring the T1/NxDS0 Lines, page 7-9
•
Configuring the E1 Lines, page 7-10
Note
Bit error rate testing (BERT) is supported on each of the T1 and E1 lines. It can be done over a framed
or unframed DS-1 signal. The OSM-12CT3/T1 module has four framers, each connected to three
contiguous ports. BER testing can be done simultenously on 6 T1 or E1 interfaces in addition to any DS3
interfaces configured on the three ports to which a framer is connected.
Note
BERT channel-groups and timeslots are also supported.
Configuring the T3 Controller for Channelization
To configure the T3 controller for T1 of E1 channelization, perform this task:
This example configures the T3 controller for T1 channelization mode:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
controller T3 2/0
Router(config-controller)#
channelized mode t1
Router(config-controller)#
CNTL/Z
Router#
Configuring the T1/NxDS0 Lines
To configure T1/NxDS0 lines, perform this task:
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
slot/port
Selects the controller.
Step 3
Router (config-controller)# [
no
]
channelized
[
mode
{
t1
|
e1
}]
Specifies the channelization mode.
Default is
t1
.
