Issue 5 October 2007 89
Cablelength
(T1
only)
The recommended maximum cable length.
Gain (T1 only) The gain on this interface. Gain represents the level of signal boost
required to transmit across the circuit at the maximum cable length.
Clock Source The source of the Transmit Clock. Possible sources include:
● Line - The recovered receive clock is used as the transmit clock.
● Internal - The local clock is used as the transmit clock.
FDL (T1 only) The type of FDL used on this interface. Possible types include:
● ANSI
● AT&T
● Both - ANSI and AT&T FDL are both used on this interface.
● None - FDL is not used on this circuit.
Local Loopback A request to use a local loopback. A local loopback can be performed
using:
● No Loopback
● Payload Loopback
● Line Loopback
● Diag Loopback
Remote
Loopback
(T1 only)
A request to use a remote loopback. A remote loopback can be performed
using:
● No Remote Loopback
● Remote Line
● Reset Remote Loopback
Loopback
Status
The type of loopback currently used by the port. Possible values are:
● No Loopback
● Near End Payload
● Near End Line
● Near End Inward
● Far End Payload
● Far End Line
Fault Messages Any faults that occurred on the port.
