bRemote Loop Idle (default)

The Remote Digital Loopback (RDL) test checks the performance of both the local and remote Model 2720s, as well as the communica- tion link between them. Data from the local DTE is sent across the entire communication circuit and looped back to the local DTE.

The Model 2720 Initiating a RL can be in one of the following states:

Idle No user-controlled loopbacks are active.

TxPr The Model 2720 is sending the preparatory phase pattern lasting for approximately 2 -5 seconds.

WtAk The Model 2720 is waiting for an acknowledgement from the remote unit. If the remote unit does not respond, the WtAk message will remain on the screen.

RxAk The Model 2720 has received an acknowledgement from the remote unit.

Tout The Model 2720 is waiting before entering the Remote Loopback test mode.

TM The Model 2720 has successfully negotiated the Remote Loopback test and is in control of the remote unit. You may send a test pattern at this point by pressing:

c <spacebar>

TxTr The Model 2720 is sending a Terminate Loopback mes- sage to the remote unit. If the remote unit does not respond, the local unit will return to the Idle state.

Tx1s If the remote Model 2720 responds to the local NetLink- T1ªÕs terminate loopback request, the local unit then sends an all ones pattern before returning to the Idle state

TxP The Model 2720 is sending a test pattern while in Test Mode

IdlP The Model 2720 is sending a test pattern in place of data. The Model 2720 is not in test mode.

The Model 2720 receiving a RL can be in one of the following states:

RxPr The Model 2720 is receiving a preparatory pattern.

Sack The Model 2720, upon receiving a preparatory pattern, sends an acknowledgement message.

RL The Model 2720 is in remote loopback mode.

RxTr The Model 2720 is receiving a terminate loopback mes- sage.

Wt1s The Model 2720 is waiting for a sequence of all ones and will time out if it does not receive it.

IdleP The Model 2720 is sending a QRSS, 511 or 2047 pattern.

Off The Model 2720 is in local loopback.

cTest Pattern Idle (default) Options: Idle or Sending

To send a pattern, press the ÔcÕ key and press <spacebar> to send the test pattern. The ÒOKÓ message indicates the received test pattern is error-free. The ÒBEÓ message indicates errors in the received pat- tern.

Idle Indicates that Model 2720 is not sending a pattern.

Sending Indicates that 2720 is sending a pattern.

dError Insertion Off (default) Options: On, Off

You may inject intentional errors into the test pattern by turning Error Insertion ON. The Error (ERR) LED will blink once per second.

eSelected Pattern

Options: QRSS, 511, or 2047

Use this option to select the test pattern used to test the link.
