Overview
The Additional Classifier Support feature allows customers to establish network connectivity between legacy voice
equipment that uses Time Division Multiplexing (TDM), for example, a customer-premise PBX and a VoIP network north of
the C4/c CMTS.
The TDM-based equipment is connected to a gateway controller that uses PRI1 interfaces. This type of equipment requires
more DOCSIS upstream flows (SIDs) than are typically supported by a cable modem.
Description
This feature permits additional classifiers per upstream flow from the cable modem. This feature requires no special
configuration or special modem configuration file TLV that was required in the original version of this feature. It is also
compatible with modems that may still contain a configuration file with the special TLV.
