Description: This attribute defines the connection model that the VISM card is configured to operate with. 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. 'switchedVoipCASBh', 'switchedVoipPRIBh', 'switchedAal2CASBh', 'switchedAal2Svc' and superMode are ignored.

'switchedAal2Pvc': Switched and trunked AAL2 PVC with CAS xGCP backhaul, CCS and CAS forwarding.

'switchedAal2Svc': Switched AAL2 SVC with PRI backhaul.

'voipAndAal1Svc': VoIP and ATM Groomer.

'voipAndAal2Trunking': VoIP Trunking And AAL2 Trunking.

'unknowMode': Unknown mode, when user change vismFeatureBitMap to a combination of Features that are not in the above modes.

This object has to be synchronized with vismFeatureBitMap. When vismFeatureBitMap is changed this object will be implicitly set to the mode that has the right combination of features.
