TL1 Commands
3.5.129 SW-TOWKG-EQPT: Switch to Working Equipment
(Cisco ONS 15454 only)
This command instructs the NE to switch the protected working unit back to working unit.
This command is used for non-SONET line cards (e.g. DS1, DS3, DS3XM, and EC1). DS1 and DS3
cards have 1:1 and 1:N equipment protection. DS3XM and EC1 cards have only 1:1 equipment
protection cards.
This command will switch the traffic from the protection card to the working card specified by the AID.
In a revertive protection group, the unit specified by the AID will clear the standing condition of
WKSWPR if the command were executed without an error. In a non-revertive protection group, the unit
specified by the AID will raise the transient condition of WKSWBK if the command were executed
without an error.
Notes:
1. This command only supports one value of the <DIRN> parameter - BTH or null. A command with
any other value is considered an incorrect use of the command. An IDNV (Input, Data Not Valid)
error message should be responsed
2. This command is not used for the common control (TCC+ or XC/XCVT) cards. A command on a
common control card will generate an IIAC (Input, Invalid Access Identifier) error message. To use
the common control card switching commands, use the SW-DX-EQPT and ALW-SWDX-EQPT
commands.
3. This command is not used for SONET (OCN) cards. A command on a SONET card will generate an
IIAC (Input, Invalid Access Identifier) error message. To use a SONET card switching command,
use the OPR-PROTNSW and RLS-PROTNSW commands.
4. If this command is used on a card that is not in a protection group, the SNVS (Status, Not in Valid
State) error message will be responsed.
5. If this command is sent to a missing working card, the SWFA (Status, Working Unit Failed) error
message will be responsed.
6. If this command is used on a protection card, the IIAC (Input, Invalid Access Identifier) error
message will be responsed.
7. If sending a mode parameter with a value other than NORM, FRCD, or null, the IDNV (Input, Data
Not Valid) error message will be responsed.
8. If sending the SW-TOWKG command to a working card when the working card has raised
INHSWWKG, the SWLD (Status, Working Unit Locked) error message will be responsed.
9. If sending the SW-TOWKG command to a working card when the protection card has raised
INHSWWKG, the SPLD (Status, Protection Unit Locked) error message will be responsed.
10. If sending the SW-TOWKG command to an active working card, the SNVS (Status, Not in Valid
State) error message will be responsed.
