Avaya 03-300430 User Manual

o. Error Type 3073: Perform the following steps for Error Type 3073:

1. Execute display errors and resolve any errors on the following: PKT-BUS, PKT-INT, 

PDATA-BD, PGATE-BD, BRI-BD, BRI-PT, BRI-SET/ASAI, UDS1-BD.

2. Enter test board location r3 for this circuit pack. If this error continues to appear, 

replace the EI circuit pack.

p. Error Types 3074 and 3075: failures of the EI circuit pack Packet Path test. This packet 

path test exercises circuitry on the EI circuit pack, the neighbor EI or SNI circuit pack, and 
any intervening DS1 converter circuit packs (if the PN is remoted).

1. Certain packet-bus faults can cause these errors without the EI being defective. Check to 

see if PKT-BUS errors are also present. If they are, use the 

on page 1799 section of this chapter and 

 in Maintenance Procedures (03-300192) to diagnose the problem.

2. If Error Type 3075 is present without Error Type 3074, replace the EI circuit pack.

3. If Error Type 3074 exists with or without 3075, run test board location on the EI, 

and follow the repair procedures for any test that does not pass.

4. If PKT-BUS errors are absent and replacing the EI does not resolve the problem, there is 

still the possibility of a packet-bus fault. See 

Maintenance Procedures (03-300192).

q. Error Type 3330 indicates a failure of a diagnostic component on the EI circuit pack. The 

failed component will not impair service, but it may leave the EI circuit pack in a state where 
the EI circuit pack cannot detect errors.

1. Replace the EI circuit pack at a time when it is most convenient for the customer (this 

may cause service outages).

r. Error Type 3585 indicates that the EI circuit pack experienced a series of very short 

out-of-frame conditions within several minutes. This may indicate transmission difficulties 
over the fiber link. If this condition ceases, the warning alarm should be resolved within 15 
minutes.

1. Enter display errors and resolve any SNC-BD, TDM-BUS, TDM-CLK or SYNC 

errors.

2. Perform the “Fiber Fault Isolation Procedure” described in Chapter 5.

3. If the alarm is not resolved within the next 15 minutes, replace the lightwave transceiver 

on the EI circuit pack reporting the problem and on the connected EI circuit pack, SNI 
circuit pack, or DS1 converter circuit pack.

4. If the alarm is not resolved within the next 15 minutes, replace the EI circuit pack 

reporting the alarm.

5. If the alarm is not resolved within the next 15 minutes, replace the connected EI circuit 

pack, SNI circuit pack or DS1 converter circuit pack.

s. Error Type 3841 indicates the EI has reported a loss of lock with the backplane system 

clock.
