This object should be used for VoIP Trunking applications and only if the signaling type is configured to be CCS(Common Channel Signaling). By default the PRI(Primary Rate Interface) D-channel information will be sent on the control channel. If the control network is totally separated from the bearer network then the user needs to set this object to 'bearer' to send his LAPD(Link Access Procedure on the D-channel) Trunk messages to the remote VISM. DEFVAL { control } ::= { vismVoIpGrp 15 } SYNTAX INTEGER { none (1), proprietary (2), all (3) } MAX-ACCESS read-write STATUS current DESCRIPTION This attribute defines whether or not the VISM should advertise the event codecs, NSE, NTE, or Cisco-rtp, in addition to the list of events specified by the call agent. If the value is 'none', then VISM will not include any more event codecs than what has been specified by the call agent. If the value is 'proprietary', then VISM can advertise proprietary event codecs in addition to the event codecs specified by the call agent. If the value is 'all', then VISM can advertise both proprietary as well as standard event codecs in addition to the event codecs specified by the call agent.

This object can be modified by CLI(Command Line Interface) only. The CLI 'cnfvismmode' can be used to set this object. VISM card will be reset after modifying this parameter for the VISM card to come up in the new mode. Each mode enables a set of features on the VISM card. The feature set for each of the above modes is : 'voipSwitching':VoIP mode. In this mode VISM interacts with the call agent using XGCP protocol, bearer path is VoIP. This mode is also used for VoIP applications that dosen't use call agent(VoIP Trunking). 'aal2Trunking': AAL2 Trunking mode. In this mode VISM does not interact with the call agent. Bearer Path is AAL2. 'aal1Svc' : AAL1 SVC(Switched Virtual Circuit) mode. In this mode VISM interacts with call agent using XGCP protocol over AAL5 control PVCs. In this mode, bearer path is VoAAL1 and the bearer connections are SVCs. i.e VISM dynamically sets-up and tears down bearer connections.

DEFVAL { voipSwitching } ::= { vismSystemGrp 5 } SYNTAX INTEGER { voipSwitching (1), aal2Trunking (2), aal1Svc (3), aal2PvcSwitching (4) } MAX-ACCESS read-only STATUS deprecated DESCRIPTION This attribute indicates the mode in which VISM was operating before the object vismMode value was changed. i.e It gives the value of vismMode before it got changed to the current value. When the card comes up in the default mode, the value of vismPrevMode will be the same as vismMode. Hence this object is no longer needed. DEFVAL { voipSwitching } ::= { vismSystemGrp 6 } SYNTAX INTEGER { disable (1), enable (2) } MAX-ACCESS read-write STATUS current DESCRIPTION This attribute describes whether CAC (Connection Admission Control) functionality needs to be applied on the VISM card, on a per PVC basis. For some applications, the CAC functionality may not be required and in that case, it has to be disabled on a card basis. DEFVAL { enable } ::= { vismSystemGrp 7 } SYNTAX Integer32 (0..248) MAX-ACCESS read-only STATUS current DESCRIPTION This attribute describes the number of DS0s available for new connections on VISM.

When a switch is made to a new template, the number of channels (endpoints) in use will be checked to ensure the switch will not occur if there are more endpoints active at the present time than what the new template allow, the number of channels per template are specify in vismCodecTemplateMaxChanCount. Also whenever an attempt is made to add a new endpoint for any template, this template maximum number will limit the number of endpoints that may be added for this template. ::= { vismSystemGrp 9 } SYNTAX SnmpAdminString (SIZE (1..64)) MAX-ACCESS read-write STATUS current DESCRIPTION This object holds the domain name of the tftp server from where the CAS module will download the CAS files. This domain name can be resolved internally or externally. Before configuring this object the domain name should be added in the mgDomainNameTable(defined in CISCO-WAN-MG-MIB MIB) and at least one IP address (internal or external) should be associated with this domain name in mgcResolutionTable (defined in the same MIB). By default, the object is set to TFTPDOMAIN. Before the last entry corresponding to the tftp domain is deleted from the mgDomainNameTable or the last IP address associated with this object is deleted from mgcResolutionTable, it should be set to 'TFTPDOMAIN'. If the user configures 'localhost' to be the tftp server domain then the cas files will be downloaded from PXM(Processor Switch Module). If the user configures the domain name to be TFTPDOMIAN or localhost then that entry need not be present in mgDomainNameTable or mgcResolutionTable. ::= { vismSystemGrp 11 } SYNTAX INTEGER { ip (1), atm (2) } MAX-ACCESS read-write STATUS current DESCRIPTION This object specifies the network type to use in order to transport bearer traffic.

DEFVAL { lcoRcdLcl } ::= { vismSystemGrp 17 } SYNTAX INTEGER { previousCodec (1), upspeedCodec (2) } MAX-ACCESS read-write STATUS current DESCRIPTION This object defines the policy that needs to be applied when a carrier loss is detected. This states whether to switch to the pre-upspeed codec or to remain with the upspeed codec. This object is applicable in case of SVCs. This object will be applicable in case of PVC if the per PVC object - vismChanCarrierLossPolicy (defined in vismChanCacTable) is set to 'unspecified'. Configuring this object will not have any affect when card level CAC is disabled (vismCacEnable). DEFVAL { previousCodec } ::= { vismSystemGrp 18 } SYNTAX INTEGER { delete (1), maintain (2) } MAX-ACCESS read-write STATUS current DESCRIPTION This attribute defines the policy that needs to be applied once the CAC function rejects the upspeeding of a connection, due to a fax/modem switch-over request. The applicable options are: 'delete' : To delete the connection that got rejected by CAC for upspeed. 'maintain' : To maintain the connection with the prior compression scheme. This object is applicable in case of SVCs. This object will be applicable in case of PVCs if the per PVC object - vismChanCacRejectionPolicy (defined in vismChanCacTable) is set to 'unspecified'. Configuring this object will not have any affect when card level CAC is disabled (vismCacEnable). DEFVAL{ maintain } ::= { vismSystemGrp 19 } SYNTAX SnmpAdminString (SIZE (1..64)) MAX-ACCESS read-write STATUS current DESCRIPTION This object refers to the domain name of the external DNS server which will be used to resolve other domain name. Currently this domain name can only be resolved internally. Therefore, before configuring this object not only the domain name has to be added in the mgDomainNameTable with resolution type 'internalOnly' but also at least one IP address has been added with this domain name in mgcResolutionTable. Before deleting external DNS server from mgDomainNameTable or deleting the last IP address associated with the external DNS server this object should be set to 'NULL'. After we change the value of this object to NULL, all the externally resolved IP address in mgcResolutionTable will be purged. By default this object will be set to 'NULL'. ::= { vismSystemGrp 20 } SYNTAX Integer32 (0..2147483647) MAX-ACCESS read-write STATUS current DESCRIPTION This object denotes the bit map for VISM features. It indicates the current features that are enabled. It should be consistent with vismMode. When user change vismMode, this object is implicitly set to the feature combination that indicate to that mode. The change of vismFeatureBitMap will not cause VISM to reset and the configuration will not be cleared. For each bit, value 1 means the feature is enabled, 0 means disabled. Bit 0 - AAL1 adaptation Bit 1 - AAL2 adaptation Bit 2 - AAL5 adaptation (Bearer network type is IP). Bit 3 - Switching (with Call Agent) Bit 4 - Trunking (without Call Agent) Bit 5 - Bearer VC type is PVC. Bit 6 - Bearer VC type is SVC. Bit 7 - CAS signaling Bit 8 - PRI backhaul Bit 9 - CCS signaling Bit 10 - Domain Name For example, 0x5AC corresponds to vismMode 1 (VoipSwitching). Currently this object is not settable, it can only be set thru some debug commands. ::= { vismSystemGrp 21 } SYNTAX Integer32(1..10000) MAX-ACCESS read-write STATUS current DESCRIPTION The value in this object refers to the customer accepted drop rate for voice connections when the bandwidth usage exceeds allowed value. The actual range of this object is 0.0001% - 1.00 % The unit is in percentage, since the default is 0.01 %, and since we cannot express such fractions in MIB , it is being multiplied by 10000 . However, when the underlying CAC module is notified of the change in this object, then the value has to be divided by a factor of 10000. Multiplication factor 10000 is picked as someone might be interested in a tolerance as low as 0.0001%. This object will be applicable in case of AAL2 SVCs where the user does not add a PVC and also this object will be applicable if the per PVC level object vismChanVADTolerance(defined in CISCO-VISM-CAC-MIB MIB) is configured to have a value of zero. Configuring this object will not have any affect when card level CAC is disabled (vismCacEnable). DEFVAL { 100 } ::= { vismSystemGrp 22 } SYNTAX Integer32 (1..100) MAX-ACCESS read-write STATUS current DESCRIPTION This object refers to the talk-spurts duty cycle. The unit is in percentage. When the value of this object is to be passed to underlying CAC module in VISM this value has to be divided by 100. This causes the actual range of this object to be 0.01 to 0.99 and not 0.01 to 1.00 as specified in the range of values above. Since a value of 100 will cause a floating point exception, this value is disallowed. The default value is 0.61 and since we cannot have fractions in a MIB variable the value is being multiplied by 100 and is expressed as 61. This object will be applicable in case of AAL2 SVCs where the user does not add a PVC and also this object will be applicable if the per PVC level object vismChanVADDutyCycle(defined in CISCO-VISM-CAC-MIB MIB) is configured to have a value of zero. Configuring this object will not have any affect when card level CAC is disabled (vismCacEnable). DEFVAL { 61 } ::= { vismSystemGrp 23 } SYNTAX INTEGER { disable (1), enable (2) } MAX-ACCESS read-write STATUS current DESCRIPTION This attribute defines the aggregate traffic clipping policy which is applicable to all bearer traffic generated at VISM card. The applicable options are: 'disable' : aggregate traffic clipping is disabled, VISM card traffic management does not perform aggregate traffic clipping.

When aggregate traffic clipping is enabled, VISM card can discard cells which are exceeding VISM card aggregate SVC bandwidth which is specified as vismAggregateSvcBandwidth value. DEFVAL { enable } ::= { vismSystemGrp 24 } SYNTAX Integer32(0..100000) MAX-ACCESS read-write STATUS current DESCRIPTION The aggregate svc bandwidth is used for AAL2 SVC aggregate SVC CAC and also used for aggregate traffic clipping at VISM card when vismAggregateTrafficClipping is enabled. This is expressed in cells per second. This need to be configured for AAL2 SVC aggregate bandwidth call admission control to admit AAL2 SVC connections at VISM card. DEFVAL { 0 } ::= { vismSystemGrp 25 } SYNTAX TruthValue MAX-ACCESS read-write STATUS current DESCRIPTION This attribute defines whether the bearer continuity test for a connection will be performed at the time of call setup or not. When the vismBearerContinuityTest is enabled, the terminating media Gateway initiates a NSE/Type 3 packet towards the originating gateway and starts a timer defined by vismBearerContinuityTimer. The originating gateway, on receipt of co3, responds by sending a co4 to the terminating end. If the terminating gateway doesn't receive co4 NSE/Type 3 packet with in the time defined by co4 timer, it initiates a GW-initiated DLCX to the call agent which in turn deletes the connection. The value in this object will be utilized when the call agent does not specify this.
