Description / Recommendation
FAIL The EI circuit pack could not detect the framing signal. Several fail codes
may be returned depending on which endpoint cot frame up. Error codes
2326, 2327, and 2328 denote Endpoint 1, Endpoint 2, and both endpoints,
respectively.
1. Clear any SYNC and TDM-CLK errors listed in the error log.
2. Run test board location for each EI board on this fiber link and
follow the appropriate repair sequence for any failing tests.
3. If the EI circuit pack that is failing Test #238 is in the PN, and the red
LEDs are ON for a large number of circuit packs, then reseat any
Tone-Clock circuit packs in the PN. See Replacing the IPSI or
Tone-Clock Circuit Pack instructions.
4. Enter display errors and follow the associated repair
procedures for any SNC-BD (Switch Node Clock Circuit Pack) (if
applicable to this fiber link configuration) or TDM-BUS (TDM Bus)
errors.
5. Perform the Fiber link fault isolation procedures described in Chapter
4: General troubleshooting in Maintenance Procedures for Avaya
Aura Communication Manager, Media Gateways and Servers
(03-300432).
6. If the test continues to abort, follow normal escalation procedures.
PASS The EI circuit pack(s) have detected the valid framing signal on the fiber.
1. Refer to errors from other EI circuit packs, SNI (SNI) tests, or DS1
Converter tests (if present) if the link is still not functioning.
2 of 2
The EI local looparound test is similar to the Lightwave Transceiver Looparound test (#242). A
test tone is received by the EI being tested, but is not transmitted out to the fiber interface
before being looped back. The loopback is internal to the circuit pack. This test does not
interfere with the normal fiber data stream.
