What Is Nortel-MsCarrier-MscPassport-GsmIwfMIB?

This Nortel MIB belongs to the MscPassport family for the Nortel Passport WAN switching platform and governs the GSM Interworking Function (IWF), a component that bridges mobile GSM circuit-switched data calls to PSTN or modem-based endpoints. It exposes provisioning data for GSM call-service trunk groups, including modem pool association, IP addressing of the mobile switching center, and virtual router assignment. Its monitoring value is chiefly operational: it lets administrators confirm that GSM interworking trunk groups are correctly provisioned and active, tracking row status and storage type to catch misconfigured or unexpectedly removed circuits, which is central to keeping mobile-to-fixed call interworking software functioning. It relies on the shared MscPassport component-object conventions (row status, storage type, component naming) used across the wider Passport MIB set. This MIB would be deployed on carrier Nortel Passport nodes acting as gateways between GSM mobile networks and traditional telephony infrastructure. Engineers can download the Nortel-MsCarrier-MscPassport-GsmIwfMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-GsmIwfMIB. 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

An operator inspects mscGsmCsProvTable, keyed by mscGsmCsTrunkGrpIndex, to verify that mscGsmCsMscIpAddress points to the correct mobile switching center and that mscGsmCsVirtualRouterName matches the intended routing context. The mscGsmCsRowStatusTable's mscGsmCsRowStatus confirms whether a given GSM call-service component is active, notReady, or destroyed. If calls routed through mscGsmCsModem start failing, checking mscGsmCsCommentText and row status on the associated trunk group entry often reveals a component left in a non-active provisioning state.

What Can Be Monitored

Once this timer expires, the transmitting Radio Link Protocol (RLP) entity shall assume that the frame was lost. During the Exchange Information (XID) negotiation, both RLP entities (mobile station and IWF) can agree to use specific value for this timer (T1). The IWF attempts to negotiate to the value specified by this attribute. The default value for t1AckTimer is 520 msec for the full14k5Rate instance of this component, 480 msec for full12kRate, 540 msec for full6kRate, and 780 msec for half6kRate. The negotiated value can be viewed in the component GsmIwfRlpOp attribute t1AckTimer. Changes to this attribute do not effect existing calls.

NUM mscGsmCsV42T400DetectTimer	1.3.6.1.4.1.562.36.2.1.127.5.10.1.1	FixedPoint2	read-write	This attribute specifies the maximum amount of time that the IWF waits for an Originator Detection Pattern (ODP) or Answerer Detection Pattern (ADP). ODP/ADP is a series of special bit patterns used during the call setup procedures. If the IWF is the Originator of the call, it starts sending ODP patterns and waits for an ADP for the duration of T400 milliseconds from the answerer at call setup time. If the IWF is the Answerer of the call, it waits for an ODP for T400 seconds from the originator and if it receives during that time it sends an ADP pattern to the originator at the call setup time. Since both sides operate with different values of T400 timer, a higher value increases the chance of a successful call setup. Changes to this attribute do not effect existing calls.
NUM mscGsmCsV42T401AckTimer	1.3.6.1.4.1.562.36.2.1.127.5.10.1.2	FixedPoint2	read-write	This attribute specifies the maximum amount of time that the IWF waits for an acknowledgment before retransmitting a frame. Since information about the T401 timer is not carried in the Exchange Identification (XID) negotiations at call setup time, both sides operate with different timer values. The value for T401 depends on many factors, such as propagation delay or frame processing time. A frame is retransmitted up to N400 times if the timer T401 expires before an acknowledgment for a frame is actually received. The performance of the data link layer can be impacted by the value of this timer as retransmissions of frames occur on expiry of timer T401. Changes to this attribute do not effect existing calls.
NUM mscGsmCsV42T402AckDelayTimer	1.3.6.1.4.1.562.36.2.1.127.5.10.1.3	FixedPoint2	read-write	This attribute specifies the maximum amount of time that the IWF may wait following the receipt of any frame requiring a reply before it initiates transmission of an appropriate reply in order to ensure that the reply frame is received by the remote error-correcting entity prior to expiration of the T401 timer of the remote error-correcting entity. Since information about the T402 timer is not carried in the Exchange Identification (XID) negotiations at call setup, both sides operate with different timer values. If this timer expires, then the reply that would have been returned prior to its expiration is not sent. The performance of the data link layer can be impacted by the value of this timer as retransmissions of frames occur on expiry of timer T401. For better performance, a value of t402AckDelayTimer (T402) equal to half the value of t401AckTimer (T401) is recommended. Changes to this attribute do not effect existing calls.
U32 mscGsmCsV42T403IdleProbeTimer	1.3.6.1.4.1.562.36.2.1.127.5.10.1.4	Unsigned32	read-write	This attribute specifies the maximum amount of time that the IWF allows to elapse without frames being exchanged. The link is permitted to remain idle with no frames being exchanged on the data link. Upon expiry of this timer, the IWF polls its peer for status. Since information about the T403 timer is not carried in the Exchange Identification (XID) negotiations at call setup time, both sides operate with different timer values. Changes to this attribute do not effect existing calls.
U32 mscGsmCsV42TxN401FrameSize	1.3.6.1.4.1.562.36.2.1.127.5.10.1.5	Unsigned32	read-write	This attribute specifies the maximum number of octets that can be carried in the information field of an Information (I) frame, Exchange Identification (XID) frame, and a Unnumbered Information (UI) frame from the IWF to the remote entity. The default value is 128 octets, and no XID negotiations required for txN401FrameSize. If the value for txN401FrameSize value is set to other than 128 octets, then XID frames are exchanged to negotiate a value. The value provided for txN401FrameSize sets up the bounds during XID negotiations. The IWF performs XID negotiations with this value as a minimum or maximum value. If a value greater than 128 is specified, then the IWF negotiates or attempts to negotiate a value between the 128 (as a minimum) and the given value (as a maximum). If a value less than 128 is specified, then the IWF attempts to negotiate a value between the given value (as a minimum) and 128 (as a maximum). Any value can be specified as long as it is within the provisionable limits. However, a value equal to or close to 128 is recommended. The negotiated value can be viewed in the component GsmIwfV42Op attribute txN401FrameSize. Changes to this attribute do not effect existing calls.
U32 mscGsmCsV42RxN401FrameSize	1.3.6.1.4.1.562.36.2.1.127.5.10.1.6	Unsigned32	read-write	This attribute specifies the maximum number of octets that can be carried in the information field of an Information (I) frame, Exchange Identification (XID) frame, and a Unnumbered Information (UI) frame from the remote entity to the IWF. The default value is 128 octets, and no XID negotiations are required for rxN401FrameSize. If the value set for rxN401FrameSize is other than 128, XID frames are exchanged to negotiate a value. The value provided for rxN401FrameSize sets up the bounds during XID negotiations. The IWF performs XID negotiations with this value as a minimum or maximum value. If a value greater than 128 is specified, then the IWF attempts to negotiate for a value between 128 (as a minimum) and the given value (as a maximum). If a value less than 128 value is specified, then the IWF attempts to negotiate for a value between the given value (as a minimum) and 128 (as a maximum). Any value can be specified as long as it is within the provisionable limits. However, a value equal to or close to the default is recommended. The negotiated value can be viewed in the component GsmIwfV42Op attribute rxN401FrameSize. Changes to this attribute do not effect existing calls.
U32 mscGsmCsV42TxKwindowSize	1.3.6.1.4.1.562.36.2.1.127.5.10.1.7	Unsigned32	read-write	This attribute specifies the maximum number of outstanding unacknowledged sequenced Information (I) frames from the IWF to the remote entity. The default value is 15 frames, and if this value is used then no Exchange Identification (XID) negotiations are required for txKwindowSize. If the value set for txKwindowSize is other than 15, then XID frames are exchanged to negotiate a value. The value provided for txKwindowSize sets up the bounds during XID negotiations. The IWF performs XID negotiations with this value as a minimum or maximum value. If a value greater than 15 is specified, then the IWF attempts to negotiate a value between 15 (as a minimum) and the given value (as a maximum). If a value less than 15 is specified, then the IWF attempts to negotiate for a value between the given value (as a minimum) and 15 (as a maximum). Any value can be specified as long at it is within the provisionable limits. However, a value equal to or close to the default is recommended. The negotiated value can be viewed in the component GsmIwfV42Op attribute txKwindowSize. Changes to this attribute do not effect existing calls.
U32 mscGsmCsV42RxKwindowSize	1.3.6.1.4.1.562.36.2.1.127.5.10.1.8	Unsigned32	read-write	This attribute specifies the maximum number of outstanding unacknowledged sequenced Information (I) frames from the remote entity to the IWF. The default value is 15 frames, and if this value is used then no Exchange Identification (XID) negotiations are required for rxKwindowSize. If the value set for rxKwindowSize is other than 15, then XID frames are exchanged to negotiate a value. The value provided for rxKwindowSize sets up the bounds during XID negotiations. The IWF performs XID negotiations with this value as a minimum or maximum value. If a value greater than 15 is specified, then the IWF attempts to negotiate a value between 15 (as a minimum) and the given value (as a maximum). If a value less than 15 is specified, then the IWF attempts to negotiate for a value between the given value (as a minimum) and 15 (as a maximum). Any value can be specified as long as it is within the provisionable limits. However, a value equal to or close to the default is recommended. The negotiated value can be viewed in the component GsmIwfV42Op attribute rxKwindowSize. Changes to this attribute do not effect existing calls.
U32 mscGsmCsV42N400RetransLimit	1.3.6.1.4.1.562.36.2.1.127.5.10.1.9	Unsigned32	read-write	This attribute specifies the maximum number of times the IWF retransmits a frame upon expiry of t401AckTimer before appropriate recovery action is taken. Information about N400 (Retransmission Limit) is not carried in the Exchange Identification (XID) negotiation at call setup time so both sides operate with different N400 values. Changes to this attribute do not effect existing calls.

INT mscGsmCsV42bisCompressionDirection	1.3.6.1.4.1.562.36.2.1.127.6.10.1.1	INTEGER	read-write	This attribute specifies the V.42bis data compression direction to be supported. The value for compression direction is negotiated at link setup by the data link protocol by way of the Exchange Identification (XID) negotiation of parameter P0 (compression direction). During XID negotiation of parameter P0, both sides (IWF and mobile or IWF and Public Switched Telephone Network (PSTN)) agree on the compression direction. Valid values are: none, No compression is present. encode, The data sent by the IWF to the other entity is compressed. decode, The data received by the IWF from the other entity is compressed. both, The data sent and received by the IWF is compressed. The negotiated value can be viewed in the component GsmIwfV42bisOp attribute compressionDirection. Changes to this attribute do not effect existing calls.

A codeword is a binary number that represents a string of characters in compressed form. V.42bis keeps a dictionary of codewords for each compression direction. During Exchange Identification (XID) negotiation of parameter P1 (number of codewords), both sides (IWF and mobile or IWF and Public Switched Telephone Network (PSTN)) agree on the total number of codewords in the dictionaries. Changes to this attribute impact the compression ratio for the encoder (component GsmV42BisOp attribute compRatioEncoder). Changes also impact the amount of memory used (more memory is used when increasing the attribute). The gain in performance obtained from the selection of a larger dictionary may be offset by the larger codeword size needed, and for certain types of data, better performance may be obtained by using a smaller dictionary. The negotiated value can be viewed in the component GsmIwfV42bisOp attribute maximumCodewords . Changes to this attribute do not effect existing calls.

Receipt of a codeword, at any time, equal to C1 (next empty dictionary entry). 3. Receipt of a codeword representing an empty dictionary entry. 4. Receipt of a reserved command code. 5. Receipt of any other error. If the value is resetLink, the error corrected connection and V.42bis dictionaries are reset. Some data is lost but the call continues. If the value is takeDownCall, the call is taken down. Changes to this attribute do not effect existing calls.
