Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

This chapter provides RLS (release) commands for the Cisco ONS 15454 SDH.

18.1  RLS-EXT-CONT

Release External Control

Usage Guidelines

This command releases a forced contact state and returns the control of the contact to an AUTOMATIC control state. In AUTOMATIC control state, the contact can be opened or closed depending on triggers that might or might not be provisioned in the NE. Therefore, issuing a RLS might not produce any contact state change.

The NE defaults to having no triggers provisioned for external controls which consequently produces default open contacts. An NE with this default provisioning will always produce an open contact with a RLS-EXT-CONT command.

---

Note•The duration is not supported; it defaults to CONTS.

•In an automatic state, the contact could be opened or closed depending on the provisioned trigger. Therefore, issuing an OPR-EXT-CONT command followed by an RLS-EXT-CONT command might not produce any contact state change.

•The RLS-EXT-CONT is not allowed during the MNTRY duration. The command is allowed for the CONTS duration. The length of MNTRY duration is set to be 2 seconds.

•RLS-EXT-CONT cannot change the contact state to Automatic if the existing state is Manual Open.

Input Parameters

Table 18-3 RLS-LPBK-<MOD2> Input Parameters 

Parameter and Values	Description
SRC	Source access identifier from the "ALL" section. The valid values for AID are FACILITY, and VC
LOCATION	The location where the operation is to be carried out. LOCATION defaults to NEND Parameter type is LOCATION—location where the action is to take place
•FEND	Action occurs on the far end of the facility
•NEND	Action occurs on the near end of the facility
LPBKTYPE	Type of loopback signal Parameter type is LPBK_TYPE—indicates the type of loopback that is to be operated or released
•CRS	Path level loopback which is established at the cross-connect matrix level. An VC level cross-connect loopback causes an AIS-P to be sent on the outgoing direction of transmission
•FACILITY	Type of loopback that connects the incoming received signal immediately following the optical-to-electrical conversion (after descrambling) to the associated transmitter in the return direction
•TERMINAL	A loopback that connects the signal that is about to be transmitted (after scrambling but before the electrical-to-optical conversion) and is connected to the associated, incoming receiver

18.4  RLS-PROTNSW-<MOD2DWDMPAYLOAD>

Release Protection Switch (10GFC, 10GIGE, 1GFC, 1GFICON, 2GFC, 2GFICON, D1VIDEO, DV6000, ETRCLO, GIGE, HDTV, ISC1, ISC3, PASSTHRU)

This command releases a Y-cable protection switch on client facilities.

18.5  RLS-PROTNSW-<PATH>

Release Protection Switch (VC3, VC44C, VC464C, VC48C, VC4, VC412C, VC46C, VC416C, VC42C, VC43C, VC11)

Usage Guidelines

This command releases an SDH path protection switch request that was established with the OPR-PROTNSW-<PATH> command. This command assumes that only one user-initiated switch is active per AID.

See Table 27-1 for supported modifiers by platform.

---

Note•This command applies to path protection configuration only.

•The VTAID should be working or protect AID only.

•Sending this command on the Drop AID will return a DENY (Invalid AID, should use working/protect AID) message.

•Use the RTRV-COND-ALL or RTRV-ALM-ALL command to retrieve the protection switching state (manual, lockout, forced).

18.6  RLS-PROTNSW-<STM_TYPE>

Release Protection Switch (STM1, STM4, STM16, STM64)

Usage Guidelines

This command releases a protection switch request.

See Table 27-1 for supported modifiers by platform.

The release of a protection switch request is applicable only to the OPR-PROTNSW protection switch commands, the user-initiated switch protection commands.

The following actions will return error messages:

•This command is not used for the common control (TCC2/TCC2P or XCVXL-10G/XCVXL-2.5G) cards. Sending a command on a common control card will return an IIAC (Input, Invalid Access Identifier) error message. To query the common control card switching commands, use the SW-DX-EQPT, and ALW-SWDX-EQPT commands.

•Sending this command to non-SDH (STM) cards will return an IIAC (Input, Invalid Access Identifier) error message. To use this command on a non-SDH card switching command, use the ALW-SWTOPROTN/SWTOWKG-EQPT and INH-SWTOPROTN/SWTOWKG-EQPT commands.

•Sending this command to query on a card that is not in a protection group will return the SNVS (Status, Not in Valid State) error message.

•Sending this command to a working card that is failed or missing will return the SWFA (Status, Working unit Failed) error message.

•Sending this command to a protect card that is failed or missing will return the SPFA (Status, Protection unit Failed) error message.

•Sending this command to a card that is not in protection will return the SNPR (Status, Not in Protection State) error message.

•Sending this command to an STM line that is already in clear mode will return a SAMS (Already in Clear Maintenance State) error message.

---

Note•Use the RTRV-COND-ALL or RTRV-ALM-ALL command to retrieve the protection switching state (manual, lockout, forced).

•DIRN is an optional parameter. A NULL value defaults to BTH for a MS-SPRing protection, BTH for 1+1 BI directional protection group, and RCV for 1+1 UNI directional protection group.

DIRN follows these rules: TRMT will always fail for any kind of protection groups. For two-fiber and four-fiber MS-SPRing protection groups both the RCV and TRMT directions will fail.

•DIRN is applicable for both 1+1 and MS-SPRing protection groups. OPR-PROTNSW applies to a MS-SPRing span/ring as shown by the following command:

"RLS-PROTNSW-STM16::FAC-5-1:A::BTH;" instructs the NE to release a line protection switch request between a working line and a protection line.

18.8  RLS-SYNCNSW

Release Synchronization Switch

Usage Guidelines

This command releases the previous synchronization reference provided by the OPR-SYNCNSW command.

In a non-revertive system, the use of the RLS-SYNCNSW command might not be appropriate. All the switching between synchronization references should be initiated with the OPR-SYNCNSW command.

Once a switch is released, a minor alarm "MANSWTOPRI", (Manual Switch to Primary Reference or Secondary...) or "FRDCSWTOPRI" (Forced Switch to Primary Reference or Secondary...), will be cleared.
