FIBER-LK (Fiber Link)
A fiber link consists of the endpoint boards that are connected via the optical fiber, the lightwave
transceivers or metallic connections on the endpoint boards, and, if administered, the DS1
Converter (DS1 converter) complex that exists between the two fiber endpoints. The fiber
endpoints are EI circuit packs and/or SNI (SNI) circuit packs.
Three types of fiber links exist in G3r systems:
Fiber link errors and alarms are generated only on fibers that have at least one SNI endpoint.
Fiber errors for fibers that have EIs as both endpoints are detected by the EI circuit pack, thus
generating off-board EXP-INTF errors and alarms. Fiber errors and alarms on EI-SNI fiber links
generate FIBER-LK and/or off-board EXP-INTF errors and alarms.
Fiber links are administered via add fiber-link F or add fiber-link next, where F is
the fiber link’s number. The 2 endpoints of the fiber are administered (EI and EI, EI and SNI, or
SNI and SNI). In a duplicated PNC configuration, both the A- and B-PNC’s fiber links are
assigned with the same fiber link’s number. The fiber links are designated by F P, where F is the
fiber link’s number and P is the PNC, A-PNC or B-PNC. In addition, a DS1 converter complex
may be assigned to the fiber link. In a duplicated PNC configuration, both the A- and B-PNC’s
DS1 converter complexes are administered with the same fiber link’s number. DS1 facilities and
parameters can be modified via change fiber-link F P.
Use display fiber-link F to see an individual fiber link. Use list fiber-link to see
every fiber link.

1. F is the fiber link number; pnc is either “a-pnc” or “b-pnc” (always “a-pnc” for a standard-,
high-, or critical-reliability system).

EI-to-EI fiber This type of fiber is an EI-to-EI connection and is only used in direct connect
PNC.
EI-SNI fiber This type of fiber is an EI-to-SNI connection and is only used in Center Stage
Switch (CSS) PNC.
SNI-SNI fiber This type of fiber is an SNI-to-SNI connection and is only used in CSS PNC
when two switch node carriers are connected in a 2- or 3-switch node
configuration.
