Setting a Loopback Configuration

Setting this parameter immediately places the port in loopback mode, without a

request from the remote test equipment. Set the loopback configuration by

specifying one of the following options:

• Payload Loopback -- Received signals are looped through the T1 framer, then

looped back for retransmission. This method maintains bit-sequence integrity

for information bits, but does not maintain the integrity of frames or

superframes.

• Line Loopback -- Received signals do not go through the framing device

before being looped back out. This method ensures minimum penetration.

• No Loopback (the default) -- This option deactivates any current loopback.

See the Loopback Configuration parameter on page A-48

for information.

Setting the Source of Send Performance Messages

On FT1 link modules, you can specify the source of send performance messages:

• Customer Inst -- Indicates that the customer installation supplies the messages

• Carrier -- Indicates that the carrier supplies the messages

See the Send Performance Measurement CR Addr parameter on page A-48

for

information.

Setting the Source of Accept Performance Messages

On FT1 link modules, you can specify the source from which the router accepts

send performance messages:

• Customer Inst -- Indicates that the router accepts messages only from the

customer installation

• Carrier -- Indicates that the router accepts messages only from the carrier

See the Accept Perf Measurement CR Addr parameter on page A-49 for

information.
