Description: Manages Zhone DSL interface configuration, line profiles, and performance statistics for xDSL access devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ZhoneDsl-MIB?

ZhoneDsl-MIB is a Zhone Technologies private enterprise MIB describing Zhone's implementation of HDSL, HDSL2, SDSL, and G.SHDSL line technologies, placing it in the DSL/broadband access line category for central-office or CPE DSL equipment. It exposes per-line configuration, such as mode/profile selection among the supported DSL variants, and performance/status data such as line rate, signal quality, and error statistics characteristic of symmetric DSL line monitoring. Its monitoring emphasis is on physical-layer line health: a degrading HDSL/SDSL/G.SHDSL line typically shows reduced sync rate, elevated error counts, or signal-quality degradation, all of which point to a copper-loop hardware fault such as moisture, damage, or distance/attenuation rather than a software issue. It commonly aligns with or complements the IETF's HDSL2-SHDSL-LINE-MIB, since Zhone's implementation covers the same underlying line technologies that standard describes. It is typically deployed on Zhone DSL line cards/CPE providing symmetric broadband access for business or backhaul circuits, and technicians can download the ZhoneDsl-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZhoneDsl-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Zhone HDSL/HDSL2/SDSL/G.SHDSL line card or CPE

Monitoring Examples

An operator would poll a given line's current sync rate and error statistics to confirm it matches the provisioned DSL mode and rate, then watch for rising error counts that suggest line degradation. A line that repeatedly fails to train up to its configured rate, or that shows a sudden jump in error seconds, points to a physical cable fault or a mismatched line profile between the two endpoints. No sample objects were listed for this MIB, so exact table/column names are unconfirmed, but conventional DSL line MIBs of this kind expose per-line rate, mode, and error-count objects.

What Can Be Monitored

DSL line mode/profile (HDSL/HDSL2/SDSL/G.SHDSL)
line sync rate
line error counts/error seconds
line operational status

OIDs

OID symbolic	OID numeric	Type	Access	Description
zhoneDslLineTable	1.3.6.1.4.1.5504.5.4.1		not-accessible	This table contains common attributes describing DSL physical line interfaces for DSLs without a MIB standard.
zhoneDslLineEntry	1.3.6.1.4.1.5504.5.4.1.1		not-accessible	An entry in the zhoneDslLine Table.
INT zhoneDslLineType	1.3.6.1.4.1.5504.5.4.1.1.1	INTEGER	read-create	The DSL type. Many modem vendors allow software selection between HDSL, HDSL2, SDSL and SHDSL. Using zhoneDslLineTypeSupported the user can see what dsl option is available on this interface.
BIT zhoneDslLineCapabilities	1.3.6.1.4.1.5504.5.4.1.1.2	Bits	read-only	The DSL types supported on this interface. This is a bit-map of possible types. This variable can be used to determine zhoneDslLineType.
INT zhoneDslLineStatus	1.3.6.1.4.1.5504.5.4.1.1.3	INTEGER	read-only	The DSL modem status. Detailed modem state maybe available in the status table.
G32 zhoneDslUpLineRate	1.3.6.1.4.1.5504.5.4.1.1.4	Gauge32	read-only	The DSL upstream (cpe->co) line rate on this interface.
G32 zhoneDslDownLineRate	1.3.6.1.4.1.5504.5.4.1.1.5	Gauge32	read-only	The DSL downstream (co->cpe) line rate on this interface.
STR zhoneDslLineConfigProfile	1.3.6.1.4.1.5504.5.4.1.1.6	ZhoneAdminString	read-create	The value of this object identifies the row in the respective dsl configuration profile table. (Ex: if zhoneDslLineType is HDSL2, then the profile identifies an HDSL2 configuration profile.) It is assumed that all profile names are unique to the system. In the case which the configuration profile has not been set, the value will be set to `ZhoneDefault'. This is a profile (by type) which will be persisted and then able to be modified by a management station in order to modify the DEFAULT values.
STR zhoneDslLineAlarmProfile	1.3.6.1.4.1.5504.5.4.1.1.7	ZhoneAdminString	read-create	The value of this object identifies the row in the respective dsl alarm profile table. (Ex: if zhoneDslLineType is HDSL2 then the profile identifies an HDSL2 alarm profile.) It is assumed that all profile names are unique to the system. In the case where the configuration profile has not been set, the value will be set to `ZhoneDefault'.
ZHO zhoneDslLineRowStatus	1.3.6.1.4.1.5504.5.4.1.1.8	ZhoneRowStatus	read-write	Row status in order to add an entry in this table. The required fields to be added are: (ARE ALL THE DEFAULTS OKAY)
zhoneHdsl2ConfigProfileTable	1.3.6.1.4.1.5504.5.4.3		not-accessible	This table contains information for HDSL2 configuration.
zhoneHdsl2ConfigProfileEntry	1.3.6.1.4.1.5504.5.4.3.1		not-accessible	An entry in the zhoneHdsl2ConfigProfile Table.
STR zhoneHdsl2ConfigProfileName	1.3.6.1.4.1.5504.5.4.3.1.1	ZhoneAdminString	not-accessible	Configuration profile name. Used by the zhoneHdsl2LineConfigProfile entry to map zhoneDslLine Entry to the appropriate profile. When `dynamic' profiles are implemented, the profile name is user specified. Also, the system will always provide a default profile whose name is `DEFVAL'. When `static' profiles are implemented, there is an one-to-one relationship between each line and its profile. In which case, the profile name will need to algorithmically represent the Line's ifIndex. Therefore, the profile's name is a decimal zed string of the ifIndex that is fixed-length (i.e., 10) with leading zero(s). For example, the profile name for ifIndex which equals '15' will be '0000000015'.
