– Remote Loop: Idle (default)
The Remote Digital Loopback (RDL) test checks the performance of both
the local and remote NetLink-T1™s, as well as the communication link
between them. Data from the local DTE is sent across the entire commu-
nication circuit and looped back to the local DTE.
The NetLink-T1™ Initiating a RL can be in one of the following states:
Idle– No user-controlled loopbacks are active.
TxPr– The NetLink-T1™ is sending the preparatory phase pattern
lasting for approximately 2 -5 seconds.
WtAk– The NetLink-T1™ is waiting for an acknowledgement from
the remote unit. If the remote unit does not respond, the WtAk mes-
sage will remain on the screen.
RxAk– The NetLink-T1™ has received an acknowledgement from
the remote unit.
Tout– The NetLink-T1™ is waiting before entering the Remote
Loopback test mode.
TM– The NetLink-T1™ 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
TxTr– The NetLink-T1™ is sending a Terminate Loopback message
to the remote unit. If the remote unit does not respond, the local unit
will return to the Idle state.
Tx1s– If the remote NetLink-T1™ responds to the local NetLink-
T1™’s terminate loopback request, the local unit then sends an all
ones pattern before returning to the Idle state
TxP– The NetLink-T1™ is sending a test pattern while in Test Mode
IdlP– The NetLink-T1™ is sending a test pattern in place of data.
The NetLink-T1™ is not in test mode.
