Total Access 3000 H2TU-C Auto In Service Status Screen
The Auto In Service Status Scr
een
( Figure 23 ) provides the status of the Auto In Service
feature.
The T1 alarm indications will display if the External Alarms option is enabled on the Provi-
sioning menu (
Figure 17 ).
The Auto In Service Status screen also indicates the startup or exit period remaining as either
1, 4, 8, or 24 hours. This is the time during which the unit monitors both loop synchroni-
zation (Loop Sync) and T1 alarms (if enabled) and will only go into (or out of) service if the
circuit remains synchronized and without T1 alarms during the entire measured period.
These times are also set from the Provisioning menu. System responses displayed in the
status fields on this screen are shown in
Table 11 below.
A single menu option is provided to view the Alarm History Screen. This screen is also
available by selecting the HDSL2 Main Menu option.
