Cisco ASR 1000 Series Software Configuration Guide

PurposeCommand or Action
If the mapping is configured to be AU-3, then the following muxing, alignment,
and mapping will be used:
VC-3 <--> AU-3 <--> AUG
Default is au-4.
Sets the clock source, where:Router(config-controller)# clock source
{internal | line}
Step 3
• 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.
Configures AU-3, AU-4, and tributary unit groups, type 3 (TUG-3) for AU-4 and
enters specific configuration mode.
Do one of the following:
Step 4
•
Router(config-controller)# au-4
au-4# tug-3 tug-3#
Depending on the framing mode of SONET or SDH, each STS-1, AU-3, TUG-3,
and AU-4 of a 1-Port Channelized OC-3/STM-1 SPA can be configured with one
of these commands.
•
•
Router(config-controller)# au-3
au-3#
Depending on currently configured AUG mapping setting, this command further
specifies TUG-3, AU-3, AU-4 or STS-1 muxing. The CLI command parser enters
into config-ctrlr-tug3 (SDH mode), config-ctrlr-au3 (SDH mode), or
config-ctrlr-sts1 parser mode (SONET mode), which makes only relevant
commands visible.
• au-4#—Range is from 1 to 4.
• tug-3#—Range is from 1 to 3.
• au-3# —Range is from 1 to 12.
Configures mode of operation for AU-3 or AU-4 mode, where:In SDH framing in AU-4 mode:
Step 5
Example:
Router(config-ctrlr-tug3)# mode
{c-11 | c-12 | t3 | e3}
C-11 and C-12 are container level-n (SDH) channelized T3s. They are types of T3
channels that are subdivided into 28 T1 channels.
• c-11—Specifies an AU-3/AU-4 TUG-3 divided into seven TUG-2s. Each
TUG-2 is then divided into four TU11s, each carrying a C-11 T1.
Example:
In SDH framing AU-3 mode:
• c-12—Specifies an AU-3/AU-4 TUG-3 divided into seven TUG-2. Each
TUG-2 is then divided into three TU12s, each carrying a C-12 E1.
• t3—Specifies an AU-3/AU-4 TUG-3 carrying an unchannelized (clear
channel) T3.
Example:
Router(config-ctrlr-au3)# mode
{c-11 | c-12 | t3 | e3 | ct3 | ct3-e1}
• e3—Specifies an AU-3/AU-4 TUG-3 carrying an unchannelized (clear
channel) E3.
Example:
• ct3—Specifies an AU-3 carrying a DS3 signal divided into 28 T1s
Plesiochronous Digital Hierarchy [PDH]).
•
ct3–e1—Specifies a channelized T3 carrying E1 circuits.
