Configuring the Controller for SONET or SDH Mode
Controller configuration is required for both SONET and SDH framing modes. To configure the
controller on the 1-Port Channelized OC-3/STM-1 SPA or 1-Port Channelized OC-12/STM-4 SPA,
complete the following step:
Configuring SONET Mode
To configure SONET mode, complete the following steps:
Command Purpose
Router(config)# controller sonet
slot/subslot/port
Selects the controller to configure and enters
controller configuration mode, where:
• slot/subslot/port—Specifies the location of
the interface.
Note The port number is always zero on the
1-Port Channelized OC-3/STM-1 SPA
and 1-Port Channelized OC-12/STM-4
SPA.
Command Purpose
Step 1
Router(config-controller)# framing
sonet
Specifies SONET as the frame type. This is the default.
Step 2
Router(config-controller)# clock source
{internal | line}
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.
Step 3
Router(config-controller)# loopback
{local | network}
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.
