Active Broadband Networks announced that its "Active Resource Manager supports the IMS Rx interface as specified in PacketCable 2.0, paving the way for the delivery of IMS services over DOCSIS networks by providing support for PCMM policy control via the Diameter-based Rx interface. Active Broadband supports PacketCable 2.0 policy control in the company's Active Resource Manager (ARM) platform, which translates IMS policy control requests into PCMM policy actions in the CMTS. The ARM also determines network topology using a unique method that ensures the accurate identification of the network elements where PacketCable 2.0 services are being delivered. The ARM's integrated PCMM policy application manager and policy server component uses this topology information to accurately direct policy control actions to the appropriate CMTS and cable modem".
