PDMODULE (Processor Data Module)
Issue 1 June 2005 1757
determine the state of the data module. The off-hook should have changed the service state
to in-service. No action is necessary.
k. Error Type 2305, Aux Data 40967: the link between the circuit pack and the data module
has been reset successfully. 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 (assuming the
associated circuit pack is plugged in and that the data module is connected to the
associated port), or when a data module is first connected to an administered port. No
system technician action is necessary.
l. Error Type 2561: the downlink buffer on the circuit pack has overflowed. No action is
necessary.
m. Error Type 2817: a DCP endpoint may have been disconnected.
n. Error Type 1, 769, 1537, 3841: make sure the data module is connected and operating
properly. Check for faulty wiring. If necessary, reduce the length of the cable between the
data module and the switch to 5000 ft. for 24-gauge wire or 4000 ft. for 24-gauge wire.
If the problem still exists, replace the circuit pack. Once the problem has been resolved, the
alarm will be retired in 60 minutes (90 min. for error 1537). (These error counters use the
leaky bucket mechanism.)
The DA module is not phantom-powered from the port. Thus when it is in linked mode, its
range is limited by the Italtel digital phone’s limit: 0.7 Km (2300 ft.) on 26-gauge wire or 1.8
Km (5900 ft.) on 22-gauge (0.6 mm) wire. If in stand-alone mode, it is limited by the
maximum length of loop allowed from the Digital Line Interface (DLI) component: up to 3.5
km (2 miles) on 22-gauge (0.6 mm) wire.
