TL1 Commands
7. If sending the inhibit switch to protection command to the protect card when a working card in the
same protection group has already raised the condition of INHSWWKG, the SWLD (Status,
Working unit Locked) error message should be responsed.
8. Sending the inhibit switch to protection command to an active protect card when the peer working
card is failed or missing, the SWFA (Status, Working unit Failed) error message should be
responsed.
9. The following situation(s) are allowed and will not generate any error response: sending this
command to missing cards as long as none of the previous error conditions apply.
3.5.45 INH-SWTOWKG-EQPT: Inhibit Switch to Working Equipment
(Cisco ONS 15454 only)
This command instructs the NE to inhibit automatic or manual switching of an equipment unit back to
the working unit. Use the ALW-SWTOWKG-EQPT command to release the inhibit.
INH-SWTOWKG-EQPT is used for non-SONET line cards (e.g. DS1, DS3, DS3XM and EC1 cards).
DS1 and DS3 cards have 1:1 and 1:N equipment protection. DS3XM and EC1 cards have only 1:1
equipment protection. When performing a lock-out with this command, the traffic will be switched from
the unit specified by the AID, unless the protection unit has failed or is missing. When performing a
lock-on with this command and the protection unit specified in the AID is in standby, sending this
command will initiate a traffic switch only when there is one working card in the protection group. In
the case where there is more than one working card in the protection group, an error will be generated
(see error conditions below). When traffic is locked on the protection unit or locked out of a working
unit with this command, the working unit will not carry traffic, even if the protection unit is pulled from
the system.

Input Format INH-SWTOPROTN-EQPT:[<TID>]:<AID>:<CTAG>[::<DIRN>];
where:
• <AID> This parameter can either be the working unit for which switching to
protection is inhibited (lock on) or the protection unit for which carrying traffic
is to be inhibited (lockout); <AID> is from the “EQPT” section on page 4-11
• <DIRN> is the direction of the switching. The command only supports one value
of the <DIRN> parameter - BTH. This parameter defaults to BTH; valid values
for <DIRN> are shown in the DIRECTION, page 35
Input Example INH-SWTOPROTN-EQPT:CISCO:SLOT-2:123::BTH;
