This field indicates the line status of the interface. It contains loopback state and failure
state information. Scroll to view all of the status information, if necessary.
T3 Line Type
Select the type of DS3 or C-bit application implementing this interface: M23 or
CbitParity. The type of interface affects the interpretation of the usage and error
statistics.
T3 Loop Back
Select the loopback configuration of the T3 interface. Options are:
No Loop Not in a loopback state. A device that is not capable of performing a
loopback on the interface will always have this value.
Payload The received signal at this interface is looped through the device.
Typically the received signal is looped back for retransmission after it
has passed through the devices’s framing function.
Line Loop The received signal at this interface does not go through the device, but
is looped back out.
Transmit Clock Source
Select the T3 Transmit Clock Source: Loop-Timing, which indicates that the recovered
receive clock is used as the transmit clock, or Local-Timing, which indicates that an
internal clock source is used.

select the desired option.
2. Click the Apply button to set your changes.
