Updates
To stop the automatic updating, type <U>. To resume automat-
ic updating, type <U> again.
9.2.3.2
Clearing Status Registers
To clear all stored historical data, type <C>. The system will
give a confirmation message prompting if all data is to be
cleared. Type <Y> for Yes or <N> for No.
- WARNING -
The clear command <C> affects all performance monitoring
screens. The clear command will clear all data screens regardless of
the activating time interval screen.
9.2.4
CIRCUIT STATUS Menu Screen
9.2.4.1
The Circuit Status screen is used to view the circuit sta-
tus of the NIU, as well as perform various test routines such as
loopback. To reach this screen from the MAIN menu, type <S>.
The Circuit Status screen, shown in Figure 17, provides a graphi-
cal representation of the NIU and its ports to the T1 facility and
customer interface.
9.2.4.2
For each port, the screen shows:
1.
Level (LVL) of the signal in dB. Possible field values are:
0
0dB level detected
-1
-1dB level detected
-2
-2dB level detected
up to
-30
-30dB level detected
LOW
Too low to measure
2.
Framing (FRMG) that is present at the port. Possible val-
ues in this field are:
SF
SF framing present
ESF
ESF framing present
UNF unframed
UNK
unknown
3.
Signal (SIG) status at the port. Possible values here are:
OK
Normal signal condition
LOS
Loss Of Signal
AIS
Alarm Indication Signal (all ones)
RAI
Remote Alarm Indication (yellow alarm)
Idle
Customer Disconnect Indication signal
RAI-CI Remote Alarm Indication - Customer Interface
AIS-CI Alarm Indication Signal - Customer Interface
9.2.4.3
The Circuit Status screen also shows a graphical repre-
sentation of the internal transmission paths of the NIU, with the
specific regeneration or LBO parameters that have been provi-
sioned. When different parameters are provisioned, remotely or
via the provisioning menu, they will be reflected here.
9.2.4.4
Facility Loopback.
By using the <Ctrl><F>keys si-
multaneously, the NIU can be placed into a loopback toward the
Facility (see Figure 18).
9.2.4.5
CPE Loopback.
By using the <Ctrl><C> keys simul-
taneously, the NIU can be placed into a loopback toward the
CPE only. The graphical representation on the Status Screen
will change appropriately to show the CPE loopback and AIS be-
ing transmitted toward the facility.
9.2.4.6
Dual Loopback.
Dual loopback is achieved by using
both <Ctrl><F> and <Ctrl><C> (see Figure 19). The
graphical representation will change appropriately to show the
