Specifications
X723-300151 1-12 Issue 2
Fault messages may be displayed directly on the local RS-232 terminal as
the faults occur, or an Alarm Service Request (ASR) mode may be selected.
In ASR mode, fault messages are not automatically displayed, instead an
ASCII BELL character is sent to the terminal every minute until the user
manually requests the new fault messages to be displayed. A printer may
be attached to the terminal to print out the faults as they are displayed.
Fault reporting from channel card circuits may be inhibited with a menu
facility, or by removing the channel card from the equipment map which
will inhibit all fault reporting for that card.
1.2.5 Real Time Clock
The 3200 is equipped with a Real Time Clock. This is used to time and
date stamp fault reports and also to log any messages received from the
NCS.
A timed event facility is provided. This facility allows the 3200 to
automatically change configuration at pre-determined time points,
allowing, for example, voice by day, data by night operation. The time
points may be on a weekly or daily basis over a 365 day period with the
provision to program up to 32 different event changes.
1.2.6 Maintenance Facilities
The 3200 supports comprehensive maintenance facilities as follows:-
Current Configuration and Channel Card Status Display
Each non Smart channel card circuit supports two 8 bit status ports.
These are used to indicate the channel card fault status, card identity code
and set -up. These ports can be useful in identifying the nature of any
active faults.
All configuration parameters may be displayed using the 'Configuration'
menu and in the 'Maintenance' menu, status port values for the channel
cards along with the current sync source and configuration running may
be displayed.
Set and Display Data
Any outgoing timeslot, or its associated signalling, may be set to a user
defined code, and any fixed incoming data or signalling may be displayed
on the local terminal. These are powerful facilities designed to easily test
circuit integrity in conjunction with various loopbacks.
