busyout fiber-link
busyout fiber-link fiber# [a-pnc | b-pnc]
NOTE:
This command is not valid for S8700 IP Connect configurations.
The busyout fiber-link command puts a specified fiber link into a maintenance
busy state. (See ‘‘Busyout and Release Commands’’ on page 7-13.) A fiber
link is a connection carrying all circuit and packet traffic between two port
networks, two switch nodes, or a port network and a switch node. A fiber link may
contain a DS1 CONV complex used to provide connectivity to a remote EPN.
!
CAUTION:
On a high-reliability system (unduplicated PNC), the busyout command is
destructive. Every call and application link carried on the busied-out fiber
link will be torn down, and new calls will not be established over the link.
On a critical-reliability system (with duplicated PNC), the command is allowed only
on a fiber link on the standby PNC, does not impact service, and requires that the
standby PNC be busied first.
For more information about fiber links, see ‘‘FIBER-LK (Fiber Link)’’ in Chapter 8.
Parameters
If neither PNC is specified, the command defaults to a-pnc.
Examples
Critical-Reliability System (duplicated PNC):
busyout fiber-link 01 b-pnc busyout fiber-link 03 (defaults to a-pnc)
fiber# The administered number assigned to the fiber link. (In a system with duplicated PNC, this
represents a fiber link pair.) List fiber-link displays a list of every fiber link with its number,
endpoint, and other useful information.
a-pnc If PNC is duplicated, this identifier is used to distinguish between the two fibers of a
duplicated pair. For an unduplicated PNC, “a-pnc” is the only valid qualifier.
b-pnc On a system with duplicated PNC, this identifier distinguishes between the two fibers of a
duplicated fiber pair. This identifier is invalid on a system with an unduplicated PNC.
