SN-CONF (Switch Node
Configuration)
A switch node carrier contains:
■ Up to 16 Switch Node Interface (SNI) TN573 circuit packs in slots 2
through 9 and slots 13 through 20
■ One or two Switch Node Clock (SNC) TN572 circuit packs in slots 10 and
12
■ An Expansion Interface (EI) TN570 circuit pack, a DS1 Converter (DS1C)
TN574 circuit pack, or no circuit pack in slot 1
■ An optional DS1 CONV circuit pack in slot 21
SN-CONF errors and alarms are generated for two types of failures:
1. Failure of a board in the switch node carrier to insert (be detected by
software).
2. A problem found by running the Configuration Audit (test #759). Test 759
is executed for either an SNI or SNC circuit pack during scheduled
maintenance or as part of the
test board UUCSS s
command.
For SNI circuit packs, test 759 queries the SNI for SNCs in the same
switch node carrier, SNI peers, DS1 CONVs, and EI or SNI neighbors that
the SNI can communicate with and compares this data to the
administered data.
For SNC circuit packs, test 759 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.
Switch node carriers are part of port network connectivity (PNC). For background
information about PNC, refer to the Maintenance Architecture and Hardware
Configurations chapters and related maintenance objects.

1. UU is the universal cabinet number (1 for PPN, 2 — 44 for EPNs). C is the carrier
designation (A, B, C, D, or E). SS is the number of the slot in which the circuit pack
resides (01 to 21). pp is the two digit port number (01, 02, ...).

2. If the error and alarm logs display the switch node carrier location UUC, (cabinet and
carrier only), run the
long
test sequence on the active SNC in the carrier, (slot 10 or 12). If
the error and alarm logs display a circuit pack location, UUCSS, run the
short
test
sequence on the alarmed SNI.
