NETI-ITS-MIB: View SNMP OID List / Download MIB

Reference: NID757. MIB for Isochronous Transport Services (ITS). ITS provides transport of isochronous (time sensitive) traffic across the DTM network in a transparent way. All the bits are transported unmodified with preserved timing information. The following services are all regarded as ITS: - PDH primary rates - Video (DVB/SD-SDI/HD-SDI) - Audio (AES-EBU) - SDH transport The MIB includes three primary conceptual tables; for configuring the trail termination points on the originating (source) and terminating (sink) side of the connection, and for configuring the interfaces. The table itsSrcTtpTable defines the trail termination points for the originating (source) side. The table itsSnkTtpTable defines the trail termination points for the terminating (sink) side. The table itsIfTable defines the interfaces. In addition to the itsIfTable, there are dedicated tables for technology specific configuration objects. The interconnection between the trail termination points shall be done through configuration in the Channel Manager MIB (NETI-CHMGR-MIB). A bi-directional connections are handled by creating two uni-directional connections, one in each direction, between the trail termination points.

The value of sysUpTime of the last change of any object in the itsIfTable.

Table with all service interfaces that is detected by the device. The table contains configuration objects common to all types of interfaces.

A reference to the index in the ifTable in the IF-MIB. If this is not known, the value is 0.

The textual name of the interface. The value of this object should be the name of the interface as assigned by the local device and should be suitable for use in commands entered at the device's console. This might be a text name, such as `e1-1:1' or a simple port number. This name would be the same as presented by the object ifName in the ifXTable.

The interface is not in loop-back mode. This is the normal operation of the interface. line(2). The interface is in loop-back mode on the line side. Everything that is received on the Rx line interface is looped back to the Tx line interface, and is also transmitted to the remote node. Data received from the remote node is ignored. dtm(3).

Data received on the Rx line interface is ignored. Enumeration: 'none': 1, 'notSupported': 0, 'line': 2, 'dtm': 3.

Timer for the loop-back mode. The loop-back mode is reset to its normal mode none(0) after the specified number of seconds.

If 1+1 protection switch is not used or supported, the primary channel is the only channel, and the object cannot be set to any other value. secondary(2). The secondary channel is used. none(3). The connection is not established, or is not 1+1 protected. It is not possible to set this value. While the value is none(3), it is not possible to set this object. Enumeration: 'none': 3, 'primary': 1, 'secondary': 2.

The alarm suppression mode. When alarms are suppressed, no alarms will be generated if a fault situation is detected on the trail termination point (TTP). Failures will still be shown by the object itsSnkTtpFailure. notSupported(0). Suppress alarms is not supported by the interface. This value can not be written. none(1). No alarms are suppressed. All alarms are reported. warning(2). Suppress alarms of severity warning only. all(3). All transmission alarms are suppressed. Enumeration: 'none': 1, 'notSupported': 0, 'warning': 2, 'all': 3.

A reference to the corresponding terminating connection in the table chmgrTConnectionTable in the Channel Manager MIB (NETI-CHMGR-MIB). The value is the index into that table, i.e. the value of chmgrTConnIndex. If 1+1 protection is used, then this object refers to the first established connection. If two channels originate from the same TTP, then the same connection is used for both channels, which are referenced by this object. If two channels originate from different TTPs, then two connections are used, one for each channel. The second connected connection is referenced by itsSnkTtpTConnection2.

Defects indicated on the trail termination point since the last time the object was read. los(0) Loss of Signal was detected. lof(1) Loss of Frame was detected. ais(2). Alarm Indication Signal was received from originating node. lop(3). Loss of Pointer was detected. This happens on DVB when the connection does not have enough capacity. Bits: 'los': 0, 'lop': 3, 'lof': 1, 'ais': 2.

A textual string describing a fault status on the trail termination point (TTP). A configuration error is regarded as a fault state, which is indicated when the administrative state is down. A network related fault can only occur when the administrative state is up. The object presents an empty string if there are no faults on the TTP.

A reference to an object that presents performance data for the trail termination point. The object is not part of this MIB. If the selected local interface (itsSnkLocalIf) does not support performance monitoring for the TTP, it is indicated by the value `0.0'.

The administrative state of the connection. The value controls the desired state of the connection from the trail termination point (TTP). up(1). The connection shall be active. down(2). The connection shall be in-active; active connection are torn down and alarms are cleared. This is the required state when changing the configuration of the TTP. Enumeration: 'down': 2, 'up': 1.

The operational state of the trail termination point (TTP). up(1). The TTP is up and a connection is established to all destinations. down(2). The connection is down to all destinations. dormant(5). The TTP is ready and is waiting for a connection to be established. Enumeration: 'down': 2, 'dormant': 5, 'up': 1.

See SNMPv2-TC. Use itsSnkTtpAdminStatus to activate and de-activate a connection. The following values are supported: active(1). The object always reads active. createAndGo(4). A new conceptual row is created representing a new trail termination point (TTP). To activate the TTP, set the administrative status to up(1), after all columnar objects have been updated. It is only possible to crate a TTP when at least one interface exists. destroy(6). The connection is terminated and the TTP is deleted.

A reference to the corresponding terminating connection in the table chmgrTConnectionTable in the Channel Manager MIB (NETI-CHMGR-MIB) for the second established connection when 1+1 protection is used where the two channel originate from two different trail termination points (TTPs). If the two channels originate from the same TTP, then only one entry is used in the chmgrTConnectionTable, referenced by itsSnkTtpTConnection, and the value of this object is then -1. The value is the index into the table, i.e. the value of chmgrTConnIndex.

Controls if termination of an 1+1 is allowed: true(1). Allows termination of two channels or connections for a 1+1 protected service. false(2). Denies termination of a second channel or connection. This prevents 1+1 protection.

Table to lookup a DSTI to an index in the itsSnkTtpTable.

One conceptual row represents one lookup entry.

The value refers to the index in table itsSnkTtpTable.
