Notes:
a. Could experience a noisy port or link. This is an off-board problem
detected by the port circuit. Check for faulty wiring, check for a defective
data module, or reduce the cabling distance between the data module
and the PBX (5000 feet for 24-gauge wire and 4000 feet for 26-gauge
wire; see Note). If the problem still exists, replace the circuit pack. Once
the problem has been resolved, the alarm is retired automatically within 60
minutes.
The DA module is not phantom-powered from the port and hence its range
is limited by the Italtel digital phone’s limit (0.7 km, 2300 feet, on 26-gauge
wire or 1.8 km, 5900 feet, on 22-gauge, 0.6 mm, wire) if in linked mode, or
by the maximum length of loop allowed from the Digital Line Interface
(DLI) component (up to 3.5 km, about 2 miles, with 22-gauge, 0.6 mm,
wire) if in stand-alone mode.
NOTE:
Refer to the DEFINITY Communications System Generic 1 and
Generic 3i Wiring,
555-204-111.
b. This error type and auxiliary data occur when at least 15 off-board
problems have been detected with the link to the data module. When an
error with the link is detected, an on-board counter is incremented.
The user could experience a noisy port or link. This is an off-board
problem detected by the port circuit. Check for faulty wiring, check for a
faulty data module, or reduce the cabling distance between the data
module and the PBX (5000 feet for 24-gauge wire and 4000 feet for
26-gauge wire; see the next Note). If the problem still exists, replace the
circuit pack. Once the problem has been resolved, the alarm is retired
automatically within 60 minutes.

c. This is an internal type error that occurs when an audit request fails.
d. This error type is logged when the port in question is busied out by
maintenance personnel. Make sure that the port is released from busyout.
e. There are problems with transmitting to the data module. This is usually an
on-board problem and can be ignored if no user complaints are received.
Otherwise, check for faulty wiring.
