COMMAND CODE: OPR-SWDX-PORT
PURPOSE
OPERATE SWITCH DUPLEX PORT
This command is for DCIM cards only. This command forces a particular reference input port on a par-
ticular DCIM card to be used. This command can be completed only if the <reference condition> for the
port has been set to ALW by the ED-PORT or ENT-PORT command.
Caution: If the port specified in this command fails, the clocks will go into holdover.
Stand-alone:
If the DCIM cards have been set for stand-alone operation (<conttype> = NO by the SET-
ATTR-CONT command), one of the following will occur:
If the specified port is on the active DCIM card: the active DCIM card, and therefore the system,
will use the signal on the specified input port.
If the specified port is on the inactive DCIM card: the inactive DCIM card, but not the system, will
use the signal on the specified input port.
1+1:
If the DCIM cards have been set for combined operation (<conttype> = 1+1 by the SET-ATTR-
CONT command), one of the following will occur:
If the specified port is on the active DCIM card: the active DCIM card, and therefore the system,
will use the signal on the specified input port.
If the specified port is on the inactive DCIM card: the inactive DCIM card will become the active
card, and the newly activated DCIM card, and therefore the system, will use the signal on the spec-
ified input port.
To determine the protection mode of the DCIM cards, use the RTRV-ATTR-CONT command (<conttype>
= NO or 1+1).
