Configuring the Channelized DS3 Mode
To configure channelized DS3 mode, complete the following steps:
SUMMARY STEPS
1.
Router(config)# controller sonet slot/subslot/port
2.
Router(config-controller)# sts-1 sts1-#
3.
Router(config-ctrlr-sts1)# t3 framing {c-bit | m23 | auto-detect}
4.
Router(config-ctrlr-sts1)# t3 clock source {internal | line}
5.
Router(config-ctrlr-sts1)# t3 loopback {local | network [line | payload] | remote [line | payload]}
6.
Router(config-ctrlr-sts1)# t3 mdl string {eic | fic | generator | lic | pfi | port | unit} string
7.
Router(config-ctrlr-sts1)# t3 mdl transmit {path | idle-signal | test-signal}
8.
Router(config-ctrlr-sts1)# t3 equipment {customer | network} loopback
9.
Router(config-ctrlr-sts1)# t3 bert pattern pattern interval 1-14400
DETAILED STEPS
PurposeCommand or Action
Selects the controller to configure and enters controller configuration mode,
where:
Router(config)# controller sonet
slot/subslot/port
Example:
Step 1
Selects STS mode and enters sts1 configuration mode.
Router(config-controller)# sts-1 sts1-#
Step 2
• sts-1#—A value from 1 to y, y being the SONET STS level.
Specifies the framing mode, where:Router(config-ctrlr-sts1)# t3 framing
{c-bit | m23 | auto-detect}
Step 3
• c-bit—Specifies C-bit parity framing.
Example:
• m23—Specifies M23 framing.
• auto-detect—Detects the framing type of the device at the end of the
line and switches to that framing type. If both devices are set to
auto-detect, c-bit framing is used. This is the default.
Example:
Sets the clock source, where:Router(config-ctrlr-sts1)# t3 clock source
{internal | line}
Step 4
• internal—Specifies that the internal clock source is used.
Example:
• line—Specifies that the network clock source is used. This is the default.
