Active Broadband Networks' Active Resource Manager (ARM) now 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.The ARM platform s designed to translate IMS policy control requests into PCMM policy actions in the CMTS. It also determines network topology where PacketCable 2.0 services are being delivered. The ARM's integrated PCMM policy application manager and policy server component uses the topology information to direct policy control actions to the appropriate CMTS and cable modem.
