DETAILED DESCRIPTION OF PROBLEM:
Because the virtual Cable Modem, vCM, is a DPoE System software entity residing in the MSO’s
controlled network and not an autonomous device located at the subscriber premise, MSOs have agreed
that Dual Provisioning Mode, DPM, is not a useful feature for DPoE 2.0. As in traditional DOCSIS, IPv4

and IPv6 is an attribute of the MAC Domain (or cable interface) in DPoE Systems. If an operator’s backoffice is IPv6-ready, then all vCMs can operate in IPv6 mode. If the operator’s back-office is only IPv4capable, then all vCMs can operate in IPv4 mode. There is no risk or utility in forcing the vCMs to
perform the more complicated DPM logic as might be needed for real Cable Modems that can be intermixed with CMs or MSO networks not capable of both IPv4 and IPv6. This EC contains the edits needed
in the OSSIv2.0 to reflect removal of DPM.
