docs Submgt3 Group Mta Filter Ds

This attribute represents the filter group applied to traffic destined to the Embedded Multimedia Terminal Adapter on the referenced CM. This value corresponds to the 'MTA Downstream Group' value of the 'Subscriber Management Filter Groups' encoding signaled during the CM registration or in its absence, to the SubFilterDownDef attribute of the Base object. The value zero or a filter group ID not configured in the CMTS means no filtering is applied to traffic destined to the Embedded Multimedia Terminal Adapter on this CM.
