Command Description Options

Dn Data Port Loopback (DPL): This option tests the channels assigned to the

data port (not the entire E1 bandwidth). The remaining channels, using

the circuit builder function, are not affected. This is a bi-directional loop

(toward the DTE and network).

1) DEACTIVATE

2) ACTIVATE

Fn Sends an industry standard CCITT Rdl loop request code toward the far

end DSU. This should result in a loopback affecting only those timeslots

assigned through the

Circuit Build Menu

to this data port.

1)LOOP DOWN

2)LOOP UP

Tn Test Pattern: Use this option to select one of the following test patterns.

Note that patterns are always transmitted toward the net, not the DTE:

• None: This option indicates that no test pattern will be used. Note that

applies only to channels mapped to the net port, not the whole net.

• QRSS: Use Quasi-Random Signal Sequence that limits the signal to a

maximum of 15 zeros that can be transmitted sequentially. These

signals contain a medley of 20-bit words (except for more than 15

consecutive 0s). It repeats every 1,048,575 bits. Also, it contains high

density sequences and low density sequences, and sequences that

change from low density to high density and vice versa (as defined by

ANSI T1.403).

1) NONE

2) QRSS

En Reset Test Counter: Use this option to reset the error counter back to 0.

At the start of a test, this counter is automatically reset.
