includes destruc tive tests. All destructive tests ab ort unless the fiber link is first
busied out. The short test sequenc e is non-destructive and can be performed
regardless of whether the fiber link is busied out.
A fiber link is a connecti on between port networks (PNs), switch nod es (SNs), or
between a PN and the Center Stage Switch (CSS). This connection is c omprised
of a bi-directional op tical fiber connec tion (optionally extended via a DS1
Converter Complex), with each end terminated on either an Expansion Interfac e
(EI) or a Switch Node Interface (SNI). Fiber links provid e the medium for circuit
and packet c onnections between PNs and for c ommunication between the SPE
and Expansion PNs (EPNs) for the CSS.
The long seq uence includes d estructive tests and requires that the fiber link be
busied out first. When a fiber is b usied out, all calls over that fib er are dropped.
clear firmware-counters clears the firmware c ounters of specified SNI, SNC or
DS1C circuit packs, or of an the entire PNC (A or B).
Parameters
Examples
Simpl ex PNC:
test fiber-link 1 l schedule
test fiber-link 10 sh r 25 sch
Duplicated PNC:
test fiber-link 1 a-pnc schedule
test fiber-link 03 b-pnc sh r 3
Output
The following display shows a typ ical result when test fiber-link 1 b-pnc is
entered.
link# The number associated with a fib er link or fiber link pair (on d uplicated
PNCs). List fiber-link displays the location of end points for each fiber
link.
a-pnc | b-pnc On Critical Reliability systems (du plicated PNC) this identifier is used to
distinguish between the tw o fibers of a duplic ated fiber pair.
Port On Critical Reliability systems (dup licated PNC) there are two fibers
associated with every fibe r link number. A-PNC and B-PNC distinguish
one from the other.
