Required Configuration Tasks
Configuring the SONET Mode
To configure the SONET mode, complete the following steps:
SUMMARY STEPS
1. Router(config-controller)# framing sonet
2. Router(config-controller)# clock source {internal | line}
3. Router(config-controller)# loopback {local | network}
4. Router(config-controller)# sts-1 {1- 12 | 1 - 3 | 4 - 6 | 7 - 9 | 10 - 12} pos
5. Router(config-controller)# sts-1 sts1-#
6. Router(config-ctrlr-sts1)# mode {ct3 | ct3-e1 | t3 | vt-15}
7. Router(config-ctrlr-sts1)# vtg vtg#

Configuring the 1-Port Channelized OC-3/STM-1 SPA and 1-Port Channelized OC-12/STM-4 SPA
Purpose
Specifies SONET as the frame type. This is the default.
Sets the clock source, where:
• 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.
Enables or disables loopback mode on a SONET controller, where:
• local loopback—Loops data from the transmit path to the receive path.
• network loopback—Loops data received on the external port to the
transmit path and back out the external port.
The default is disabled loopback.
Configures the CHOC12 SONET controller for the OC12 POS mode and the
OC3 POS mode by specifying that the STS-1s be bundled together for POS.
Specifies the SONET Synchronous Transport Signal (STS) level and enters
STS1 configuration mode, where:
• sts-1 #—Number from 1 to 3 for the 1-Port Channelized OC-3/STM-1
SPA, and 1 to 12 for the 1-Port Channelized OC-12/STM-4 SPA.
Specifies the mode of operation of an STS-1 path, where:
• ct3—A STS-1 carrying a DS3 signal is divided into 28 T1s
(Plesiochronous Digital Hierarchy [PDH]).
• ct3-e1—The channelized T3 is carrying E1 circuits.
