This variable is used as the basis for SNMP naming of tdmaCsV42 components. These components cannot be added nor deleted.

This variable provides the component's string name for use with the ASCII Console Interface

This variable represents the storage type value for the tdmaCsV42 tables.

This variable represents the index for the tdmaCsV42 tables.

This group contains the provisionable attributes for the V.42 protocol used for the calls set up by this particular IwfCallServer. Changes to these attributes do not affect existing calls.

An entry in the tdmaCsV42ProvTable.

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 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 affect existing calls.

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 affect existing calls.

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 affect existing calls.

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 affect existing calls.

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. Changes to this attribute do not affect existing calls.

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. Changes to this attribute do not affect existing calls.

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. Changes to this attribute do not affect existing calls.

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. Changes to this attribute do not affect existing calls.

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 affect existing calls.

This attribute specifies whether a 16 bit or a 32 bit Frame Check Sequence (FCS) will be used for the link between the IWF and the far end DCE. This attribute has one of the following values: fcs16: Use only a 16 bit FCS. fcs32Or16: 32 bit FCS is preferred; Use a 16 bit FCS if needed. fcs32Only: Use only a 32 it FCS; If unavailable, drop the connection.

This group contains the provisionable attributes for the V.42bis data compression protocol parameters used for the calls set up by this particular CallServer. Changes to these attributes do not affect existing calls.

An entry in the tdmaCsV42BisProvTable.

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 PSTN) agree on the compression direction. This attribute has one of the following values: noCompression: No compression is present. compInitrResp: The data sent by the IWF to the other entity is compressed. compRespInitr: The data received by the IWF from the other entity is compressed. compBoth: The data sent and received by the IWF is compressed. Changes to this attribute do not affect existing calls. Enumeration: 'noCompression': 0, 'compInitrResp': 1, 'compBoth': 3, 'compRespInitr': 2.

This attribute specifies the maximum number of V.42bis codewords the IWF supports. 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. Changes to this attribute impact the compression ratio for the encoder (component TdmaBc V42Bis 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. Changes to this attribute do not affect existing calls.

This attribute specifies the maximum number of characters allowed in a string represented by a codeword that the IWF supports. Each codeword in a V.42bis dictionary represents a string of characters. Changes to this attribute impact the compression ratio for the encoder. Changes to this attribute do not affect existing calls.

This attribute specifies whether or not V.42bis takes down the call or resets the link when any of the following errors occur: 1.Receipt of STEPUP (step up codeword size) codeword when it would cause C2 (current code word size) to exceed N1 (maximum code word size). 2. 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 affect existing calls. Enumeration: 'resetLink': 0, 'takeDownCall': 1.

Every operator session also has a CID, which is the CID provisioned for the operator's user ID. An operator will see only the stream data for components having a matching CID. Also, the operator will be allowed to issue commands for only those components which have a matching CID. An operator CID of 0 is used to identify the Network Manager (referred to as 'NetMan' in DPN). This CID matches the CID of any component. Values 1 to 8191 inclusive (equivalent to 'basic CIDs' in DPN) may be assigned to specific customers.

This group contains the three OSI State attributes. The descriptions generically indicate what each state attribute implies about the component. Note that not all the values and state combinations described here are supported by every component which uses this group. For component-specific information and the valid state combinations, refer to NTP 241-7001-150, Passport Operations and Maintenance Guide.

An entry in the tdmaBcStateTable.

This attribute indicates the OSI Administrative State of the component. The value locked indicates that the component is administratively prohibited from providing services for its users. A Lock or Lock - force command has been previously issued for this component. When the value is locked, the value of usageState must be idle. The value shuttingDown indicates that the component is administratively permitted to provide service to its existing users only. A Lock command was issued against the component and it is in the process of shutting down. The value unlocked indicates that the component is administratively permitted to provide services for its users. To enter this state, issue an Unlock command to this component. Enumeration: 'locked': 0, 'shuttingDown': 2, 'unlocked': 1.

This attribute indicates the OSI Operational State of the component. The value enabled indicates that the component is available for operation. Note that if adminState is locked, it would still not be providing service. The value disabled indicates that the component is not available for operation. For example, something is wrong with the component itself, or with another component on which this one depends. If the value is disabled, the usageState must be idle. Enumeration: 'disabled': 0, 'enabled': 1.

This attribute indicates the OSI Usage State of the component. The value idle indicates that the component is not currently in use. The value active indicates that the component is in use and has spare capacity to provide for additional users. The value busy indicates that the component is in use and has no spare operating capacity for additional users at this time. Enumeration: 'active': 1, 'idle': 0, 'busy': 2.
