h. Error Type 2305: The station went off-hook while it was in the ready-for-service state. Use 

status station to determine the state of the station. The off-hook should have moved 

the station to ready-for-service. No technician action is necessary.

i. Error Type 3840: No terminal is connected to the Digital Line board. No maintenance 

action is required.

j. Error Type 3841: The circuit pack’s message buffer is full. This may be caused by having 

many display phones with heavy traffic connected to the circuit pack. No action is 
necessary.

k. Error Type 2304: Internal system error; no action is necessary. The error counters 1, 2, 3, 

4, 5, 6, 10, 11, 12, 13, 14, 15, and 16 do not have any significance for this MO.

Always investigate tests in the order presented in the following table when inspecting errors in 
the system. By clearing error codes associated with the Voice and Control Channel Local Loop 
Around test (#13), you may also clear errors generated from other tests in the testing sequence.

One or more Network Processing Elements (NPEs) reside on each circuit pack with a TDM-bus 
interface. The NPE controls port connectivity and gain and provides conferencing functions on a 
per-port basis. The NPE Crosstalk test verifies that this port’s NPE channel talks on the 
selected time slot and never crosses over to time slots reserved for other connections. If the 
NPE is not working correctly, 1-way and noisy connections may be observed. This test is part of 
a port’s long test sequence and takes about 20 to 30 seconds to complete. Crosstalk testing 
occurs on both the primary information channel (voice) and the secondary information channel 
(data) associated with each digital station port. If this test fails on either channel, the station and 
the DTDM are taken out of service.
