Administrative and Service States

This appendix describes administrative and service states for Cisco ONS 15454 cards, ports, and cross-connects. For circuit state information, see Chapter 10, "Circuits and Tunnels." Software Release 5.0 states are based on the generic state model defined in Telcordia GR-1093-CORE, Issue 2 and ITU-T X.731.

0.1  Service States

Service states include a Primary State (PST), a Primary State Qualifier (PSTQ), and one or more Secondary States (SST). Table 0-1 lists the service state PSTs and PSTQs supported by the ONS 15454.

Table 0-1 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 0-2 defines the SSTs supported by the ONS 15454.

Table 0-2 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 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.

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.


0.2  Administrative States

Administrative states are used to manage service states. Administrative states consist of a PST and an SST. Table 0-3 lists the administrative states supported by the ONS 15454. See Table 0-2 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 0-3 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 member cross-connect from service and from the group of members.


0.3  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.

0.3.2  Port and Cross-Connect Service State Transitions

Table 0-5 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 IS-NR.

The following ports do not support all of the service states listed in Table 0-5:

•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.
