PRVT-PW-TDM-MIB: View SNMP OID List / Download MIB

This MIB contains managed object definitions for encapsulating TDM (T1, E1, T3, E3, NxDS0) as pseudo-wires over packet-switching networks (PSN).

This table contains basic information including ifIndex, and pointers to entries in the relevant TDM config tables for this TDM PW.

This table is indexed by the same index that was created for the associated entry in the PW Table (in the PW-STD-MIB). An entry is created in this table by the agent for every entry in the prvtPwVcTable with a prvtPwVcType of 'TDM'.

The ID of the CES Module where the crcuit is configured.

The ID of the CES Circuit that this PW represents.

Specifies the type of TDM PW. The connection assumed to be symmetrical having the same value at both ends. To identify structured vs. unstructured type for DS1 and E1, dsx1LineType and dsx1SignalMode [DS1MIB] should be referenced. DS3 and E3 are always unstructured. Enumeration: 'nXds0WithCASe1': 8, 'ds3': 4, 'ds1': 2, 'octetAlignedT1': 6, 'other': 1, 'nXds0WithCASds1Sf': 10, 'nXds0': 7, 'e1': 3, 'nXds0WithCASds1Esf': 9, 'e3': 5.

Index to the relevant TDM configuration table entry that appears in one of the related MIB modules such as SAToP, TDMoIP or CESoPSN. It is likely that multiple TDM PWs of the same characteristic will share a single configuration entry of the relevant type.

The number of seconds, including partial seconds, that have elapsed since the beginning of the current measurement period. If, for some reason, such as an adjustment in the system's time-of-day clock, the current interval exceeds the maximum value, the agent will return the maximum value.

The number of previous 15-minute intervals for which data was collected. An agent with TDM capability must be capable of supporting at least n intervals. The minimum value of n is 4, The default of n is 32 and the maximum value of n is 96. The value will be unless the measurement was (re-) started within the last (*15) minutes, in which case the value will be the number of complete 15 minute intervals for which the agent has at least some data. In certain cases(e.g., in the case where the agent is a proxy) it is possible that some intervals are unavailable. In this case, this interval is the maximum interval number for which data is available.

The following defects should be detected and reported upon request: -Stray packets MAY be detected by the PSN and multiplexing layers. Stray packets MUST be discarded by the CE-bound IWF and their detection MUST NOT affect mechanisms for detection of packet loss. -Malformed packets are detected by mismatch between the expected packet size (taking the value of the L bit into account) and the actual packet size inferred from the PSN and multiplexing layers. Malformed in-order packets MUST be discarded by the CE-bound IWF and replacement data generated as for lost packets. -Excessive packet loss rate is detected by computing the average packet loss rate over the value of prvtPwVcTDMAvePktLossTimeWindow and comparing it with a preconfigured threshold [SATOP]. -Buffer overrun is detected in the normal operation state when the CE bound IWF's jitter buffer cannot accommodate newly arrived packets. -Remote packet loss is indicated by reception of packets with their R bit set. -Packet misorder is detected by looking at the Sequence number provided by the control word. -TDM Fault, if L bit in the control word is set, it indicates that TDM data carried in the payload is invalid due an attachment circuit fault. When the L bit is set the payload MAY be omitted in order to conserve bandwidth. Note: the algorithm used to capture these indications is implementation specific. Bits: 'packetLoss': 7, 'packetsRbitCounter': 10, 'tdmFault': 8, 'strayPacket': 1, 'bufferUnderrun': 5, 'excessivePktLossRate': 3, 'bufferOverrun': 4, 'other': 0, 'packetsLbitCounter': 9, 'remotePktLoss': 6, 'malformedPacket': 2.

The state of TDM indicators when the TDM PW last declared an error second (either as ES, SES or a second with errors inside a UAS) condition. At this time, only LOPS can create a failure. Since indicators other than LOPS are useful, all are latched here. For bit definitions, see prvtPwVcTDMCurrentIndications above. Note: the algorithm used to latch these indications when entering an defect state is implementation specific. Bits: 'staryPacket': 1, 'packetLoss': 7, 'packetsRbitCounter': 10, 'tdmFault': 8, 'bufferUnderrun': 5, 'excessivePktLossRate': 3, 'bufferOverrun': 4, 'other': 0, 'packetsLbitCounter': 9, 'remotePktLoss': 6, 'malformedPacket': 2.

This table contains a set of parameters that may be referenced by one or more TDM PWs in prvtPwVcTDMTable.

These parameters define the characteristics of a TDM PW. They are grouped here to ease NMS burden. Once an entry is created here it may be re-used by many PWs.

The value of this object indicates the PayLoad Size to be defined during the PW setUp. Upon TX, implementation must be capable of carrying that amount of data. Upon RX, When the LEN field is set to 0, the payload of packet MUST assume this size, and if the actual packet size is inconsistent with this length, the packet MUST be considered to be malformed.

If set True: as CE bound packets are queued in the jitter buffer, out of order packets are re-ordered. The maximum sequence number differential (i.e., the range in which re-sequencing can occur) is dependant on the depth of the jitter buffer. See prvtPwVcTDMCfgJtrBfrDepth. NOTE: Some implementations may not support this feature. The agent is then required to set this False.

If set False: an RTP header is not pre-pended to the TDM packet.

The size of the Jitter buffer SHOULD be defined to a value that is capable to allow accommodation to the PSN-specific packet delay variation. If configured to a value not supported by the implementation, the agent MUST return an error code 'jtrBfrDepth' in 'prvtPwVcTDMConfigError ' NOTE: jitter buffers are a limited resource to be managed.

The current 15 minute interval counts are in this table. This table provides per TDM PW performance information.

An entry in this table is created by the agent for every prvtPwVcTDM entry. After 15 minutes, the contents of this table entry are copied to a new entry in the prvtPwVcTDMPerfInterval table and the counts in this entry are reset to zero.

This table provides performance information per TDM PW similar to the prvtPwVcTDMPerfCurrentTable above. However, these counts represent historical 15 minute intervals. Typically, this table will have a maximum of 96 entries for a 24 hour period, but is not limited to this.

An entry in this table is created by the agent for every prvtPwVcTDMPerfCurrentEntry that is 15 minutes old. The contents of the Current entry are copied to the new entry here. The Current entry, then resets its counts to zero for the next current 15 minute interval.

A number (normally between 1 and 96 to cover a 24 hour period) which identifies the interval for which the set of statistics is available. The interval identified by 1 is the most recently completed 15 minute interval, and the interval identified by N is the interval immediately preceding the one identified by N-1. The minimum range of N is 1 through 4. The default range is 1 through 32. The maximum value of N is 1 through 96.

This variable indicates if the data for this interval is valid.
