Data Port Diagnostics Menu Commands
When finished configuring the data port diagnostics parameters,
enter X to return to the Diagnostics Menu.
Performance / Status Menu
Use the Performance/Status Menu to monitor the functioning and
condition of the network ports. The parameters in this screen
provide counts for the various problems occuring in a given period
of time. Performance information is logged in 15 minute intervals
over a 24 hour period.
To access the Performance/Status Menu, enter P from the Main
Menu, Figure 3-1.

Command Description Options
Dn Data Port Loopback (DPL)—Tests the channels assigned to the data port (not
the entire T1 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
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.
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
Fn Send FT1 Code—This option sends loop codes in the timeslots being used to
set a data port loop at the remote port.
1) Loop down
2) Loop up
En Reset Test Counter—This option resets the error counter back to 0. At the
start of a test, this counter is automatically reset.
X Exit the Data Port Diagnostics Menu screen, and return to the Diagnostics
Menu, Figure 3-18, Table 3-16.
