This notification indicates that a service indicated by the gBondTdimServiceIfIdx in a particular G.Bond TDIM port' is passing traffic. This notification MAY be send for the G.Bond TDIM port, while the port is Up, when the gBondTdimServiceOperState object has left the Down state. Generation of this notification is controlled by the gBondTdimServiceUpDownEnable object.

This notification indicates that a service indicated by the gBondTdimServiceIfIdx in a particular G.Bond TDIM port' has stopped passing the traffic. This notification MAY be send for the G.Bond TDIM port, while the port is Up, when the gBondTdimServiceOperState object has entered the Down state. Generation of this notification is controlled by the gBondTdimServiceUpDownEnable object.

Table for Configuration of G.Bond TDIM ports. Entries in this table MUST be maintained in a persistent manner

An entry in the G.Bond TDIM Port Configuration table. Each entry represents an G.Bond TDIM port indexed by the ifIndex. Additional conifguration parameters are available via the gBondPortConfEntry of GBOND-MIB. Note that an G.Bond TDIM port runs on top of a single or multiple BCE port(s), which are also indexed by ifIndex.

A desired state of the OPTIONAL Forward Error Correction (FEC) function of the G.Bond TDIM port. A value of 'false' indicates that the FEC function is disabled. A value of 'true' indicates that the FEC SHALL be enabled, if supported by the G.Bond TDIM port, as indicated by the gBondTdimFecSupported object. For the GBS-R ports, the value of this object cannot be changed directly. This value may be changed as a result of writing operation on the gBondTdimFecSupported object of a remote GBS-C. Modifications of this object MUST be performed when the link is Down. Attempts to change this object MUST be rejected (in case of SNMP with the error inconsistentValue), if the link is Up or Initializing or if it is an GBS-R. This object MUST be maintained in a persistent manner. This object maps to G.998.3 attribute aFECAdminState

The various bit positions are: serviceDown - at least one of the services defined for this aggregation group is down (due to low rate). wrongConfig - at least one BCE at the remote GBS-R is already connected to another GBS. This object is intended to supplement ifOperStatus object in IF-MIB and gBondFltStatus in GBOND-MIB. Bits: 'wrongConfig': 1, 'serviceDown': 0.

Table of Services in G.Bond TDIM ports. Entries in this table MUST be maintained in a persistent manner

An entry in the G.Bond TDIM Port Service table, containing the management information applicable to a particular Service in a G.Bond TDIM port, indexed by the gBondTdimServiceIdx.

G.Bond TDIM Service index - a unique index associated with a particular service entry, indicating relative placement of the service inside the G.Bond/TDIM frame. There can be up to 60 services defined over TDIM bonded facility. Services with lower indices have higher priority in case of bandwidth degradation. This objects maps to G.998.3 attribute aServiceID.

This is a unique index within the ifTable. It represents the interface index of a service to be transmitted over the G.Bond/TDIM service instance. This objects maps to WT-159 attribute aServiceIfIndex.

G.Bond TDIM Service Type. Possible values are: ds1 - Clear Channel DS1 (synchronous) e1 - Clear Channel E1 (synchronous) nxds0 - Fractional DS1 (synchronous) nxe0 - Fractional E1 (synchronous) ds3 - DS3 (synchronous) e3 - E3 (synchronous) clock - Clock transfer (synchronous) ethernet - Ethernet (asynchronous) atm - ATM (asynchronous) gfpNoFCS - GFP encapsulated without FCS (asynchronous) gfp - GFP encapsulated with FCS (asynchronous) For the GBS-R ports, the value of this object cannot be changed directly. This value may be changed as a result of writing operation on the gBondTdimServiceType object of a remote GBS-C. Modifications of this object MUST be performed when the link is Down. Attempts to change this object MUST be rejected (in case of SNMP with the error inconsistentValue), if the link is Up or Initializing or if it is an GBS-R. This object MUST be maintained in a persistent manner. This object maps to G.998.3 attribute aServiceType Enumeration: 'clock': 6, 'gfp': 10, 'atm': 8, 'ds3': 4, 'nxe0': 3, 'gfpNoFCS': 9, 'ethernet': 7, 'nxds0': 2, 'ds1': 0, 'e1': 1, 'e3': 5.

Service size in octets per bonding sub-block for a specific service identified by gBondTdimServiceIdx. For TDM (synchronous) services with variable size e.g. fractional DS1/E1 - this object represents the number of DS0/E0 channels. For asynchronous services (Ethernet, ATM, GFPnoFCS or GFP) - this object represents max. number of octets. A GET operation returns current value. A SET operation, allowed on GBS-C only when the link is Down, changes the service size to the indicated value. If the link is not down or the service type is fixed rate TDM service (gBondTdimServiceType is NxDS0, NxE0, DS1, E1, DS3, E3 or Clock), the operation MUST be rejected (in case of SNMP with the error inconsistentValue). This object MUST be maintained in a persistent manner. This object maps to G.998.3 attribute aServiceSize

G.Bond TDIM Service Operation State. Possible values are: up - Service is up passing traffic. down - Service is down, due to a variety of reasons, e.g. G.Bond TDIM port is down, current link bandwidth is too low to support a particular service, etc. Enumeration: 'down': 2, 'up': 1.
