9-1455SNI-BD (SNI Circuit Pack)
9
NOTE:
For descriptions of result codes for this test refer to:
■ SNC-BD when the circuit pack tested is a Switch Node Clock (circuit pack
slots 10 or 12).
■ SNI-BD when the circuit pack tested is a Switch Node Interface (circuit
pack slots 2-9 or 13-20).
This test is run via the
test board short
or
test board long
command for SNI
circuit packs or SNC circuit packs.
For SNI circuit packs, this test queries the SNI for SNCs in the same switch node
carrier, SNI peers, DS1Cs, and EI or SNI neighbors that the SNI can
communicate with and compares this data to the administered data.
For SNC circuit packs, this test queries the SNC for SNCs and SNIs in the same
switch node carrier that the SNC can communicate with and compares this data
to the administered data.
Failures of this test cause entries in the error and alarm logs against Switch Node
Configuration (SN-CONF) with the board location of the SNI or SNC.
Incorrectly Connected Administered Fibers
Some physically connected fibers that do not match fiber administration can
cause port network problems that are not detected and alarmed by PNC tests.
The symptoms will usually be many phone calls not working correctly, and port
network component alarms because of translation mismatches.
This test is unable to detect the case where an SNI is connected to the same type
of board (EI or SNI) as administered but located in a different cabinet but the
same carrier and same slot as the administered fiber endpoint. The administered
fiber endpoint can be viewed with the
list fiber-link
command. This test can only
detect if the fiber endpoint connected to the SNI is in a different carrier, slot
location than the administered fiber endpoint.
Incorrectly Connected Administered SNI-EI Fibers
If the SNI is connected to the same type of fiber endpoint as the administered
fiber endpoint, but the location is the same as administered except for the
cabinet, many phone calls will not work correctly; some phone calls will not go
through and some phone calls will ring the wrong phone.
The test led command can be used in this case to check connectivity.
1. Run the test led port-network command on each administered port
network and verify that the LEDs on the correct port network are lit.
2. If they are not lit, check that the fiber connections to the port network are
consistent with the administered fibers (list fiber-link) that does not light
the LEDs as expected.
