EXP-INTF (Expansion Interface Circuit Pack)
the PN will have been disrupted. If this system does have duplicated Port Network
Connectivity, the system should have switched to the standby Port Network Connectivity.
1. Enter reset board location for this EI circuit pack.
2. If error 1538 is detected again, replace the EI circuit pack.
j. Error Type 2049 with Aux Data 117: there is a problem with the fiber optic interface (FOI),
that is generating bit errors. Sometimes these bit errors may be constant. This error could
be caused by a crimped fiber, a fiber that is not seated correctly in the transceiver, or a
defective transceiver.
k. Error Type 2305 with Aux Data 118: the EI circuit pack has detected slips on the incoming
fiber data stream. That is, a PN in a Direct Connect configuration, or a PN and a Switch
Node in a Center Stage Switch configuration, are not synchronized.
1. Enter display errors and follow the repair procedures for non-slip errors against
any of the following:
SYNC (Port Network Synchronization)
TDM-CLK (TDM Bus Clock)
TONE-BD (Tone-Clock Circuit Pack)
DS1C-BD (DS1 Converter Circuit Pack)
EXP-INTF (Expansion Interface Circuit Pack)
SNC-BD (Switch Node Clock Circuit Pack)
SNI-BD (SNI Circuit Pack)
Non-slip errors are those not listed below:
Circuit Pack Name Name in Error Log Log Entry (for Slips)
DS1 Interface DS1-BD 3073 to 3160
Expansion Interface EXP-INTF 2305
SNI SNI-BD 1537
Tone-Clock TDM-CLK 1025
UDS1 Interface UDS1-BD 3073 to 3160
DS1 converter circuit pack DS1C-BD 3329
2. For slip errors, see SYNC (Port Network Synchronization).
l. Error Type 2306 indicates on-board failures related to system timing and synchronization.
Perform the Fiber link fault isolation procedures described in Chapter 4: General
troubleshooting of Maintenance Procedures for Avaya Aura Communication Manager,
Media Gateways and Servers (03-300432).
m. Error Type 2561 indicates an on-board failure of EI circuitry related to handling packet data
from the fiber interface and from the packet bus interface.
1. If this error has generated a minor alarm, the EI circuit pack should be replaced.
