Vt Commands Under Sonet Framing - Cisco 10000 Series Configuration Manual

Chapter 6 1-Port Channelized OC-12/STM-4 Line Card Configuration
AU-4-TUG-3 Controller
For an AU-4-TUG-3 controller, the syntax is:
Router(config-controller)# controller au-4-tug-3 <slot>/<subslot>/<port>.<AU-4#>/<TUG-3#>
The twelve AU-4-TUG-3 controllers created on an SDH-framed SONET port are based on the same
Note
higher order path and do not operate independently from one another. In other words, when you
"shutdown" any AU-4-TUG-3 controller, the other two controllers on the same SDH-framed SONET
port are also shut down.
For example, the following command uses TUG-3 #3 on AU-4 of port 0 of an 1-Port Channelized
OC-12/STM-4 line card in slot 2.
Router(config-controller)# controller au-4-tug-3 2/0/0.1/3

VT Commands under SONET Framing

This section describes how to use the controller vt command to further channelize the SONET-framed
STS-1 controller of the1-Port Channelized OC-12/STM-4 line card.
Entering Controller Configuration Mode for VT
A virtual tributary (VT) controller on a 1-Port Channelized OC-12/STM-4 line card can be channelized
into 28 T1 (VT1.5) interfaces or 21 E1 (VT2) interfaces. You can use the controller vt command to shut
down a VT link or to change the settings for a T1 or E1 interface.
For information about T1 configuration settings, see
or SDH Framing" section on page
Framing" section on page
You can configure a VT link by entering the controller vt command.
slot/sub-slot/port.path
Where path is a value from 1 to 12. Each number represents a VT that houses 28 T1 lines or 21 E1 lines.
For example:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller vt 1/0/0.1
Router(config-controller)#
Unchannelized T3 Commands under SONET or SDH Framing
This section shows you how to configure an unchannelized T3 on a SONET-framed or SDH-framed
controller.
If the 1-Port Channelized OC-12/STM-4 line card is configured for SONET framing, a T3 interface is
channelized into 28 T1 interfaces by default. You must unchannelize the T3 interface to create a full-rate or
subrate T3 interface.
If the 1-Port Channelized OC-12/STM-4 line card is configured for SDH framing, C-3 container mode
automatically creates an unchannelized T3 serial interface.
