includes destructive tests. All destructive tests abort unless the fiber link is first
busied out. The short test sequence is non-destructive and can be performed
regardless of whether the fiber link is busied out.
A fiber link is a connection between port networks (PNs), switch nodes (SNs), or
between a PN and the Center Stage Switch (CSS). This connection is comprised
of a bi-directional optical fiber connection (optionally extended via a DS1
Converter Complex), with each end terminated on either an Expansion Interface
(EI) or a Switch Node Interface (SNI). Fiber links provide the medium for circuit
and packet connections between PNs and for communication between the SPE
and Expansion PNs (EPNs) for the CSS.
The
long
sequence includes destructive tests and requires that the fiber link be
busied out first. When a fiber is busied out, all calls over that fiber are dropped.
clear firmware-counters
clears the firmware counters of specified SNI, SNC or
DS1C circuit packs, or of an the entire PNC (A or B).
Parameters
Examples
Simplex 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 typical result when test fiber-link 1 b-pnc is
entered.
link#
The number associated with a fiber link or fiber link pair (on duplicated
PNCs).
List fiber-link
displays the location of endpoints for each fiber
link.
a-pnc | b-pnc
On Critical Reliability systems (duplicated PNC) this identifier is used to
distinguish between the two fibers of a duplicated fiber pair.
Port On Critical Reliability systems (duplicated PNC) there are two fibers
associated with every fiber link number. A-PNC and B-PNC distinguish
one from the other.
