Administrative and Service States

This appendix describes administrative and service states for Cisco ONS 15454 cards, ports, and cross-connects. For circuit state information, refer to Chapter 11 "Circuits and Tunnels." Entity states in Software Release 5.0 and later are based on the generic state model defined in Telcordia GR-1093-CORE, Issue 2 and ITU-T X.731.

This appendix contains the following sections:

•Service States

•Administrative States

•Service State Transitions

B.1  Service States

Service states include a Primary State (PST), a Primary State Qualifier (PSTQ), and one or more Secondary States (SST). Table B-1 lists the service state PSTs and PSTQs supported by the ONS 15454.

Table B-1 ONS 15454 Service State Primary States and Primary State Qualifiers

Primary State, Primary State Qualifier
Definition

IS-NR

(In-Service and Normal) The entity is fully operational and will perform as provisioned.

OOS-AU

(Out-of-Service and Autonomous) The entity is not operational because of an autonomous event.

OOS-AUMA

(Out-of-Service and Autonomous Management) The entity is not operational because of an autonomous event and has also been manually removed from service.

OOS-MA

(Out-of-Service and Management) The entity has been manually removed from service.


Table B-2 defines the SSTs supported by the ONS 15454.

Table B-2 ONS 15454 Secondary States 

Secondary State
Definition

AINS

(Automatic In-Service) The entity is delayed before transitioning to the IS-NR service state. The transition to IS-NR depends on the correction of conditions, or on a soak timer. Alarm reporting is suppressed, but traffic is carried. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command.

DSBLD

(Disabled) The entity was manually removed from service and does not provide its provisioned functions. All services are disrupted; the entity is unable to carry traffic.

Note OC-N ports and connections in the DSBLD state continue to send an Alarm Indication Signal Line (AIS-L).

FLT

(Fault) The entity has a raised alarm or condition.

LPBK

(Loopback) The entity is in loopback mode.

MEA

(Mismatched Equipment) An improper card is installed. For example, an installed card is not compatible with the card preprovisioning or the slot. This SST applies only to cards.

MT

(Maintenance) The entity has been manually removed from service for a maintenance activity but still performs its provisioned functions. Alarm reporting is suppressed, but traffic is carried. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command.

OOG

(Out of Group) The virtual concatenation (VCAT) member cross-connect is not used to carry VCAT group traffic. This state is used to put a member circuit out of the group and to stop sending traffic. OOS-MA,OOG only applies to the cross-connects on an end node where VCAT resides. The cross-connects on intermediate nodes are in the OOS-MA,MT service state.

SWDL

(Software Download) The card is involved in a software and database download. This SST applies only to cards.

UAS

(Unassigned) The card is not provisioned in the database. This SST applies only to cards.

UEQ

(Unequipped) The card is not physically present (that is, an empty slot). This SST applies only to cards.


B.2  Administrative States

Administrative states are used to manage service states. Administrative states consist of a PST and an SST. Table B-3 lists the administrative states supported by the ONS 15454. See Table B-2 for SST definitions.

Note A change in the administrative state of an entity does not change the service state of supporting or supported entities.

Table B-3 ONS 15454 Administrative States

Administrative State (PST,SST)
Definition

IS

Puts the entity in service.

IS,AINS

Puts the entity in automatic in-service.

OOS,DSBLD

Removes the entity from service and disables it.

OOS,MT

Removes the entity from service for maintenance.

OOS,OOG

(VCAT circuits only) Removes a VCAT cross-connect cross-connect from service and from the group of members.

Note Only CE-100T-8 cards in link capacity adjustment scheme (LCAS) mode and FC_MR-4 (enhanced mode) cards in software LCAS (SW-LCAS) mode accept the OOG state.


B.3  Service State Transitions

This section describes the transition from one service state to the next for cards, ports, and cross-connects. A service state transition is based on the action performed on the entity.

Note When an entity is put in the OOS,MT administrative state, the ONS 15454 suppresses all standing alarms on that entity. All alarms and events appear on the Conditions tab. You can change this behavior for the LPBKFACILITY and LPBKTERMINAL alarms. To display these alarms on the Alarms tab, set the NODE.general.ReportLoopbackConditionsOnOOS-MTPorts to TRUE on the NE Defaults tab.

B.3.2  Port and Cross-Connect Service State Transitions

Table B-5 lists the port and cross-connect service state transitions. Port states do not impact cross-connect states with one exception. A cross-connect in the OOS-AU,AINS service state cannot transition autonomously into the IS-NR service state until the parent port is in the IS-NR service state.

You cannot transition a port from the IS-NR service state to the OOS-MA,DSBLD service state. You must first put the port in the OOS-MA,MT service state. Once a port is in the OOS-MA,MT state, the NODE.general.ForceToOosDsbldStateChange default setting of TRUE allows you to put a port in OOS-MA,DSBLD even if the following conditions exist:

•The port is a timing source.

•The port is used for line, section, or tunneling DCC.

•The port supports 1+1 protection or bidirectional line switched rings (BLSRs).

•Cross-connects are present on the port.

•Overhead connections or overhead terminations are in use (such as express orderwire, local orderwire, or user data channels [UDCs]).

To change this behavior so that you cannot put a port in OOS-MA,DSBLD if any of these conditions exist, set the NODE.general.ForceToOosDsbldStateChange default setting to FALSE. For the procedure to change node defaults, refer to the "Maintain the Node" chapter in the Cisco ONS 15454 Procedure Guide.

The following ports do not support all of the service states listed in Table B-5:

•E-Series Ethernet ports do not support service states; these ports are either enabled or disabled.

•FC_MR-4 ports support the IS-NR; OOS-MA,DSBLD; and OOS-MA,MT service states; they do not support the OOS-AU,AINS service state.

Note Deleting a port or cross-connect removes the entity from the system. The deleted entity does not transition to another service state.

Note The DS1 port service state on the DS3XM-12 card is based on the DS3 service state.

B.3.3  Pluggable Equipment Service State Transitions

The service state transitions for pluggable equipment are the same as for other equipment with the exceptions listed in Table B-6.

Note Pluggable equipment (pluggable interface modules [PIMs] and pluggable port modules [PPMs]) will transition out of the UAS state when inserted if the software can read the EEPROM and identify information on the pluggable equipment. If the software cannot read the pluggable equipment, the equipment is considered invalid and will not transition out of the UAS state.
