Command
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).
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
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).
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.
