Wherever possible, the PacketCable components and protocols build on existing protocols and infrastructures to simplify implementation and interoperability. All DOCSIS cable modems provide high-speed data connectivity to the Internet, while other cable modems can provide additional features, such as telephone connectivity. A typical CMTS services between several hundred and several thousand cable modems. Call management server CMS —A centrally located server that provides the signaling functions that allow MTAs to establish calls over the network. The CMS uses the Network-based call signaling NCS protocol to provide authentication and authorization, call routing, and support for special features such as three-way calling. A gate is a logical entity in the CMTS that ensures that a service flow is authorized for the QoS features it is requesting.

The CMS uses the Network-based call signaling NCS protocol to provide authentication and authorization, call routing, and support for special features such as three-way calling.

A gate is a logical entity in the CMTS that ensures that a service flow is authorized for the QoS features it is requesting. A separate gate controls the upstream and downstream directions of a service flow.

The GC is also responsible for coordinating the creation of the two sets of gates at each end of the call so that the call can be authorized and established. Note A PacketCable network can contain multiple GCs, although only one server at a time is in control of any particular call.

Record keeping server RKS —Billing server that collects the information about each call as it is made. This prevents possible theft-of-service attacks and guarantees customers the services they are authorized to use. Note PacketCable 1.

To ensure secure NCS signaling, a dynamic key exchange is performed. Attempting to generate both types of records simultaneously can significantly degrade system performance. The content of the CDBs is outside the scope of this document. Description of the Event Message Feature EMs are real-time data records containing information about network usage and activities.
