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 switchover 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. 'unspecified' - The CAC rejection policy as defined in the card level object vismCacRejectionPolicy(defined in CISCO-VISM-MODULE-MIB MIB) will be used, else the value of this object will be used. Note that the default value of maintaining the prior encoding scheme is applicable in the trunking application only since the connection is not deleted after the fax/modem switchover.In the case of switching application, the connection is deleted after the fax/modem switchover. Configuring this object will not have any affect when card level CAC object vismCacEnable(defined in CISCO-VISM-MODULE-MIB MIB) is disabled.
