EXP-INTF (Expansion Interface Circuit Pack)
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,
BRI-BD, BRI-PT, BRI-SET/ASAI, UDS1-BD.
2. Enter test board location r 3 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. The 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 if
PKT-BUS errors are also present. If they are, see PKT-INT (Packet Interface) and
Isolating and repairing packet-bus faults in Maintenance Procedures (03-300432) 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
may be a packet bus fault. See Isolating and repairing packet-bus faults in Maintenance
Procedures (03-300432).
q. Error Type 3330: 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: 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 (Switch Node Clock Circuit Pack),
TDM-BUS (TDM Bus), TDM-CLK (TDM Bus Clock) or SYNC (Port Network
Synchronization) errors.
s. Perform the Fiber link fault isolation procedures described in Chapter 4: General
troubleshooting of Maintenance Procedures (03-300432).
1. 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.
2. If the alarm is not resolved within the next 15 minutes, replace the EI circuit pack
reporting the alarm.
3. 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.
t. Error Type 3841: the EI has reported a loss of lock with the backplane system clock.
