What Is ACC-DS1?

ACC-DS1 is a vendor MIB (ACC, later part of Ericsson) for managing DS1 (T1, 1.544 Mbps) digital transmission interfaces on ACC/Ericsson access/routing equipment. It belongs to the WAN transmission-interface management category, covering DS1 line configuration such as framing format and line coding, plus performance and alarm monitoring per the short description. Its monitoring value is centered on hardware/link status: DS1 alarm conditions such as loss of signal, loss of frame, or AIS, and performance statistics such as errored seconds, reveal degrading or failed T1 circuits, which is critical for diagnosing WAN connectivity problems at the physical layer. This module aligns with, and likely extends, the IETF DS1/E1 MIB (RFC 1406/2495) framework for standard T1 interface management, adapted to ACC's specific hardware. It is typically deployed on ACC/Ericsson WAN access routers and multiplexers using leased T1 lines, in service-provider or enterprise WAN access networks, where ACC-DS1 SNMP monitoring helps flag degrading or failed T1 circuits before outages occur.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACC-DS1. 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.

Monitoring Examples

No module description or sample object list is available for this entry, so exact object names cannot be confirmed. Based on its documented purpose, an operator would typically poll DS1 line configuration (framing, line coding) and alarm/performance-history objects to detect a T1 circuit reporting loss-of-signal or elevated errored-seconds counts, indicating a failing local loop or carrier-side transmission problem, but no concrete OIDs are available for this entry.

What Can Be Monitored

DS1 framing and line-coding configuration
DS1 alarm status (loss of signal/frame)
DS1 performance/error statistics

INT accDs1ExtLineIndex	1.3.6.1.4.1.5.1.1.42.1.1	INTEGER	read-only	This object is the identifier of a DS1 Interface on a managed device. It has the same value as dsx1LineIndex.
INT accDs1ExtLineLength	1.3.6.1.4.1.5.1.1.42.1.2	INTEGER	read-write	The approximate line length. When equipped with a DSX1 line interface module, this object selects the transmit equalization. When equipped with a CSU interface module, this object selects the line build out (LBO).
INT accDS1ExtNfasGroup	1.3.6.1.4.1.5.1.1.42.1.3	INTEGER	read-write	The ifIndex of another DS1 interface whose common signaling channel (e.g., ISDN D channel) carries signaling information for this DS1 interface.
INT accDs1ExtInterfaceId	1.3.6.1.4.1.5.1.1.42.1.4	INTEGER	read-write	The internal interface on which signalling is received. 0 indicates the D-channel.
INT accDs1ExtE1Type	1.3.6.1.4.1.5.1.1.42.1.5	INTEGER	read-write	The type of E1 equipment to which the device is connected. Only used to work around Nordic type switch anomolies.
INT accDs1ExtXcvr	1.3.6.1.4.1.5.1.1.42.1.6	INTEGER	read-write	The type of transceiver installed.
INT accDs1ExtPrecedence	1.3.6.1.4.1.5.1.1.42.1.7	INTEGER	read-write	When the interface is provisioned as a PRI interface with D-channel backup, this object determines whether the D channel on this interface is the primary or secondary D channel.
INT accDs1ExtSignalGroup	1.3.6.1.4.1.5.1.1.42.1.8	INTEGER	read-write	The index of the Signal group assigned to this interface. The value of the trunk group index is limited to the maximum number of PRI interfaces that can be installed on a given platform (3 for Amazon, 28 for Tigris). A trunk group value of 0 indicates that the interface does not belong to a PRI trunk group. Replaces accDs1ExtNfasGroup which has been deprecated.
INT accDs1ExtNumberGroup	1.3.6.1.4.1.5.1.1.42.1.9	INTEGER	read-write	The index of the called number group assigned to this interface. Number groups are defined in the Called Number Table. A number group value of 0 indicates that no called number group has been assigned to this interface.
INT accDs1ExtIntegAccess	1.3.6.1.4.1.5.1.1.42.1.10	INTEGER	read-write	Indicates whether this interface has enabled integrated access. If enabled, the signal group is used as the signaling channel for this interface.
