24-gauge wire and 4000 feet for 26-gauge wire; see Note). If the problem
still exists, it may be due to the fact that the PTC is in the "tripped" position
due to a short on the power line. This can be corrected by removing the
short, unplugging the data module from the wall for about 30 seconds,
and plugging it back in. If the problem persists, replace the Digital Line
circuit pack. Once the problem has been resolved, the alarm is retired
after a predetermined period of time since this counter uses a "leaky
bucket" strategy.
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.

g. An in-line maintenance error has generated an off-board warning due to
some problem with the link to the data module. This can be ignored if no
user complaints are received. Otherwise, make sure the data module is
connected, 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 90 minutes.

h. This indicates that the data equipment went off-hook while the associated
link was being initialized (in a disconnected state). Use the status
data-module command to determine the state of the data module. The
off-hook should have changed the service state to in-service. No system
technician action is necessary.
i. This is the resulting code that is generated when the link between the
circuit pack and the data module is successfully reset. The link is normally
reset when the circuit pack associated with an administered port is first
plugged in (assuming that the data module is already in place and
connected to the associated port), when a port is first administered
