The objects in this MIB module are used to manage the multi-pair bonded xDSL interfaces, as defined in ITU-T Recommendations G.998.1, G.998.2, and G.998.3. This MIB module MUST be used in conjunction with a bonding scheme-specific MIB module, that is, G9981-MIB, G9982-MIB, or G9983-MIB. The following references are used throughout this MIB module: [G.998.1] refers to: ITU-T Recommendation G.998.1: 'ATM-based multi-pair bonding', January 2005. [G.998.2] refers to: ITU-T Recommendation G.998.2: 'Ethernet-based multi-pair bonding', January 2005.

This notification indicates that the G.Bond port's upstream data rate has reached/dropped below or exceeded the low upstream rate threshold, specified by gBondPortConfThreshLowUpRate. This notification MAY be sent for the -O subtype ports while the port is 'up', on the crossing event in both directions: from normal (rate is above the threshold) to low (rate equals the threshold or is below it) and from low to normal. This notification is not applicable to the -R subtypes. It is RECOMMENDED that a small debouncing period of 2.5 sec, between the detection of the condition and notification, be implemented to prevent simultaneous LinkUp/LinkDown and gBondLowUpRateCrossing notifications from being sent. The adaptive nature of the G.Bond technology allows the port to adapt itself to the changes in the copper environment; e.g., an impulse noise, alien crosstalk, or a micro-interruption may temporarily drop one or more BCEs in the aggregation group, causing a rate degradation of the aggregated G.Bond link. The dropped BCEs would then try to re-initialize, possibly at a lower rate than before, adjusting the rate to provide the required target SNR margin. Generation of this notification is controlled by the gBondPortConfLowRateCrossingEnable object. This object maps to the TR-159 notification nGroupLowUpRateCrossing.

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

An entry in the G.Bond Port Configuration table. Each entry represents a G.Bond port indexed by the ifIndex. Note that a G.Bond GBS port runs on top of a single or multiple BCE port(s), which are also indexed by the ifIndex.

A desired bonding scheme for a G.Bond GBS port. The following values instruct the port to use the corresponding bonding scheme if supported: none(0) - instructs the port not to use bonding (only on a single-BCE G.998.2 GBS) g9981(1) - instructs the port to use G.998.1 bonding g9982(2) - instructs the port to use G.998.2 bonding g9983(3) - instructs the port to use G.998.3 bonding Changing of the gBondPortConfAdminScheme object MUST be performed when the link is administratively 'down', as indicated by the ifAdminStatus object in the IF-MIB. Attempts to change this object MUST be rejected (in the case of SNMP, with the error inconsistentValue), if the link is 'up' or initializing. Attempts to change this object to an unsupported bonding scheme (see gBondPortCapSchemesSupported) SHALL be rejected (in the case of SNMP, with the error wrongValue). Setting this object to the value of 'none' must be rejected for GBS ports with multiple BCEs (with the error inconsistentValue). This object maps to the TR-159 attribute aGroupAdminBondScheme.

A desired bonding scheme for a peer (link partner) G.Bond port (GBS). The following values instruct the peer port to use the corresponding bonding scheme if supported: none(0) - instructs the port not to use bonding (only on a single-BCE G.998.2 GBS) g9981(1) - instructs the port to use G.998.1 bonding g9982(2) - instructs the port to use G.998.2 bonding g9983(3) - instructs the port to use G.998.3 bonding Changing of this object MUST be performed when the link is administratively 'down', as indicated by the ifAdminStatus object in the IF-MIB. Attempts to change this object MUST be rejected (in the case of SNMP, with the error inconsistentValue), if the link is 'up' or initializing. Attempts to change this object to an unsupported bonding scheme (see gBondPortCapPeerSchemesSupported) SHALL be rejected (in the case of SNMP, with the error wrongValue). Setting this object to the value of 'none' must be rejected for GBS ports with multiple BCEs (with the error inconsistentValue). This object maps to the TR-159 attribute aGroupPeerAdminBondScheme.

A discovery code of the G.Bond port (GBS). A unique 6-octet-long code used by the Discovery function. This object MUST be instantiated for the -O subtype GBS before write operations on the gBondBceConfRemoteDiscoveryCode (Set_if_Clear and Clear_if_Same) are performed by BCEs associated with the GBS. The initial value of this object for -R subtype ports after reset is all zeroes. For -R subtype ports, the value of this object cannot be changed directly. This value may be changed as a result of a write operation on the gBondBceConfRemoteDiscoveryCode object of a remote BCE of -O subtype, connected to one of the local BCEs associated with the GBS. Discovery MUST be performed when the link is administratively 'down', as indicated by the ifAdminStatus object in the IF-MIB. Attempts to change this object MUST be rejected (in the case of SNMP, with the error inconsistentValue), if the link is 'up' or initializing. This object maps to the TR-159 attribute aGroupDiscoveryCode.

A desired G.Bond port data rate in the upstream direction, in Kbps, to be achieved during initialization, under restrictions placed upon the member BCEs by their respective configuration settings. This object represents a sum of individual BCE upstream data rates, modified to compensate for fragmentation and encapsulation overhead (e.g., for an Ethernet service, the target data rate of 10 Mbps SHALL allow lossless transmission of full-duplex 10-Mbps Ethernet frame stream with minimal inter-frame gap). Note that the target upstream data rate may not be achieved during initialization (e.g., due to unavailability of required BCEs) or the initial bandwidth could deteriorate, so that the actual upstream data rate (gBondPortStatUpDataRate) could be less than gBondPortConfTargetUpDataRate. The value is limited above by 10 Gbps, to accommodate very high speed bonded xDSL interfaces (e.g., 32 x 100 Mbps). The value between 1 and 10000000 indicates that the total upstream data rate of the G.Bond port after initialization SHALL be equal to the target data rate or less, if the target upstream data rate cannot be achieved under the restrictions configured for BCEs. In cases where the copper environment allows a higher upstream data rate to be achieved than that specified by this object, the excess capability SHALL be either converted to an additional SNR margin or reclaimed by minimizing transmit power. The value of 0 means that the target data rate is not fixed and SHALL be set to the maximum attainable rate during initialization (best effort), under specified spectral restrictions and with a desired SNR margin per BCE. This object is read-write for the -O subtype G.Bond ports. It is irrelevant for the -R subtypes -- attempts to read or change this object for such ports MUST be rejected (in the case of SNMP, with the error inconsistentValue). Changing of the target upstream data rate MUST be performed when the link is administratively 'down', as indicated by the ifAdminStatus object in the IF-MIB. Attempts to change this object MUST be rejected (in the case of SNMP, with the error inconsistentValue), if the link is 'up' or initializing. This object maps to the TR-159 attribute aGroupTargetUpRate.

A desired G.Bond port data rate in the downstream direction, in Kbps, to be achieved during initialization, under restrictions placed upon the member BCEs by their respective configuration settings. This object represents a sum of individual BCE downstream data rates, modified to compensate for fragmentation and encapsulation overhead (e.g., for an Ethernet service, the target data rate of 10 Mbps SHALL allow lossless transmission of full-duplex 10-Mbps Ethernet frame stream with minimal inter-frame gap). Note that the target downstream data rate may not be achieved during initialization (e.g., due to unavailability of required BCEs) or the initial bandwidth could deteriorate, so that the actual downstream data rate (gBondPortStatDnDataRate) could be less than gBondPortConfTargetDnDataRate. The value is limited above by 10 Gbps, to accommodate very high speed bonded xDSL interfaces (e.g., 32 x 100 Mbps). The value between 1 and 10000000 indicates that the total downstream data rate of the G.Bond port after initialization SHALL be equal to the target data rate or less, if the target downstream data rate cannot be achieved under the restrictions configured for BCEs. In cases where the copper environment allows a higher downstream data rate to be achieved than that specified by this object, the excess capability SHALL be either converted to an additional SNR margin or reclaimed by minimizing transmit power. The value of 0 means that the target data rate is not fixed and SHALL be set to the maximum attainable rate during initialization (best effort), under specified spectral restrictions and with a desired SNR margin per BCE. This object is read-write for the -O subtype G.Bond ports. It is irrelevant for the -R subtypes -- attempts to read or change this object for such ports MUST be rejected (in the case of SNMP, with the error inconsistentValue).

This object maps to the TR-159 attribute aGroupTargetDownRate.

This object configures the G.Bond port low upstream rate crossing alarm threshold. When the current value of gBondPortStatUpDataRate for this port reaches/drops below or exceeds this threshold, a gBondLowUpRateCrossing notification MAY be generated if enabled by gBondPortConfLowRateCrossingEnable. This object is read-write for the -O subtype G.Bond ports. It is irrelevant for the -R subtypes -- attempts to read or change this object for such ports MUST be rejected (in the case of SNMP, with the error inconsistentValue). This object maps to the TR-159 attribute aGroupthreshLowUpRate.

This object configures the G.Bond port low downstream rate crossing alarm threshold.

An entry in the GBS PM TCA Configuration table. Each entry corresponds to a single TCA configuration profile. Each profile contains a set of parameters for setting alarm thresholds for various performance attributes monitored at GBS ports. Profiles may be created/deleted using the row creation/deletion mechanism via gBondPortPmTcaProfileRowStatus. If an active entry is referenced via gBondPortConfPmTcaConfProfile, the entry MUST remain active until all references are removed. A default profile with an index of 'DEFVAL' will always exist, and its parameters will be set to vendor-specific values unless otherwise specified in this document.

This object is a unique index (name) associated with this GBS PM TCA profile.

A desired threshold for the number of Errored Seconds (ES) within any given 15-minute performance data collection interval. If the number of ESs in a particular 15-minute collection interval reaches or exceeds this value, a gBondPmTca15MinESCrossing notification MAY be generated if enabled by gBondPortConfPmTcaEnable. At most one notification can be sent per interval. Setting this attribute to zero (default) effectively disables the gBondPmTca15MinESCrossing notification. This object maps to the TR-159 attribute aGroupPerfThreshold15MinES.

A desired threshold for the number of Severely Errored Seconds (SES) within any given 15-minute performance data collection interval. If the number of SESs in a particular 15-minute collection interval reaches or exceeds this value, a gBondPmTca15MinSESCrossing notification MAY be generated if enabled by gBondPortConfPmTcaEnable. At most one notification can be sent per interval. Setting this attribute to zero (default) effectively disables the gBondPmTca15MinSESCrossing notification. This object maps to the TR-159 attribute aGroupPerfThreshold15MinSES.

A desired threshold for the number of Unavailable Seconds (UAS) within any given 15-minute performance data collection interval. If the number of UASs in a particular 15-minute collection interval reaches or exceeds this value, a gBondPmTca15MinUASCrossing notification MAY be generated if enabled by gBondPortConfPmTcaEnable. At most one notification can be sent per interval. Setting this attribute to zero (default) effectively disables the gBondPmTca15MinUASCrossing notification. This object maps to the TR-159 attribute aGroupPerfThreshold15MinUAS.

A desired threshold for the number of Errored Seconds (ES) within any given 1-day performance data collection interval. If the number of ESs in a particular 1-day collection interval reaches or exceeds this value, a gBondPmTca1DayESCrossing notification MAY be generated if enabled by gBondPortConfPmTcaEnable. At most one notification can be sent per interval. Setting this attribute to zero (default) effectively disables the gBondPmTca1DayESCrossing notification. This object maps to the TR-159 attribute aGroupPerfThreshold1DayES.

A desired threshold for the number of Severely Errored Seconds (SES) within any given 1-day performance data collection interval. If the number of SESs in a particular 1-day collection interval reaches or exceeds this value, a gBondPmTca1DaySESCrossing notification MAY be generated if enabled by gBondPortConfPmTcaEnable. At most one notification can be sent per interval. Setting this attribute to zero (default) effectively disables the gBondPmTca1DaySESCrossing notification. This object maps to the TR-159 attribute aGroupPerfThreshold1DaySES.

A desired threshold for the number of Unavailable Seconds (UAS) within any given 1-day performance data collection interval. If the number of UASs in a particular 1-day collection interval reaches or exceeds this value, a gBondPmTca1DayUASCrossing notification MAY be generated if enabled by gBondPortConfPmTcaEnable. At most one notification can be sent per interval. Setting this attribute to zero (default) effectively disables the gBondPmTca1DayUASCrossing notification. This object maps to the TR-159 attribute aGroupPerfThreshold1DayUAS.

This object controls the creation, modification, or deletion of the associated entry in the gBondPortPmTcaProfileTable per the semantics of RowStatus. If an 'active' entry is referenced via gBondPortConfPmTcaConfProfile instance(s), the entry MUST remain 'active'. An 'active' entry SHALL NOT be modified. In order to modify an existing entry, it MUST be taken out of service (by setting this object to 'notInService'), modified, and set to 'active' again.

Table for configuration of G.Bond common aspects for the Bonding Channel Entity (BCE) ports (modems/channels). Entries in this table MUST be maintained in a persistent manner.

An entry in the G.Bond BCE Configuration table. Each entry represents common aspects of a G.Bond BCE port indexed by the ifIndex. Note that a G.Bond BCE port can be stacked below a single GBS port, also indexed by the ifIndex, possibly together with other BCE ports if bonding is enabled.

A remote discovery code of the BCE port at the CO. A 6-octet-long discovery code of the peer GBS connected via the BCE. Reading this object results in a Discovery Get operation. Setting this object to all zeroes results in a Discovery Clear_if_Same operation (the value of gBondPortConfDiscoveryCode at the peer GBS SHALL be the same as gBondPortConfDiscoveryCode of the local GBS associated with the BCE for the operation to succeed). Writing a non-zero value to this object results in a Discovery Set_if_Clear operation. A zero-length octet string SHALL be returned on an attempt to read this object when bonding is not enabled. This object is irrelevant in BCE-R port subtypes (CPE side): in this case, a zero-length octet string SHALL be returned on an attempt to read this object. An attempt to change this object MUST be rejected (in the case of SNMP, with the error inconsistentValue). Discovery MUST be performed when the link is 'down'. Attempts to change this object MUST be rejected (in the case of SNMP, with the error inconsistentValue), If the link is 'up' or initializing. This object maps to the TR-159 attribute aLineRemoteDiscoveryCode.
