3.2.3 System Diagnostics

The System Diagnostics/Statistics screen looks like this:

NOTE: This screen is updated once per second.

The System Diagnostics/Statistics options and functions are described below.

aLocal Loop: Idle (default)

The Local Loop is a bi-lateral loopback in which the data from the local DTE and the data from the remote unit are looped back to their respective sources (See Section 5.3). Activate this loop to test the each of the DTE’s connection to the Model 2720.

The Local Loop test has four states:

Idle No user-controlled loopbacks are active.

LLThe Model 2720 is in local loopback mode.

Off The Model 2720 is in remote or CO initiated loopback mode or sending a pattern. Local loopback is disabled.

LocP The Model 2720 is in Local Loopback mode, and is send- ing a test pattern.

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- T1™’s 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:
