CCS Enhancements

Prior to this feature, the communication between the ISDN Series 3 card and the Matrix Controller Series 3 card uses the mid-plane HDLC bus. Communication over the HDLC bus slows the maximum number of messages that can be transmitted to be less than 100 per second, not allowing the user to achieve high call rates that require ISDN services.

Using Ethernet communication for messaging between a ISDN Series 3 card and Matrix Controller Series 3 card allows increased performance by providing more message transactions per second.

This feature supports a new RCOMM state machine on the ISDN Series 3 card that monitors the status of the link between this card and Matrix Controller Series 3 card. Communication over the HDLC bus will continue to be supported. Licensing of this feature is not required.

Prior to this feature, when the PPL Event Request for ANM is sent either to L3P CIC component of ANSI/ITU or to L3P BT IUP component the L4CH SM is not in the answered state. To put the L4CH SM in answered state, you needed to use a custom PPL.

This feature puts the L4CH SM in an answered state when the PPL Event Request for ANM is sent to either of the following:

See Integrated Services Digital Network.

The protocol used in most local area PC networks. Typically, most Ethernet networks support data transmission speeds up to 10 Mbps, but 100 Mbps is also possible.

The Matrix Controller Series 3 card is based on Motorola’s 750 PowerPC processor (68750). It is often referred to as the Matrix Controller.

The condition of a component at a given instant. The current "context" of a PPL object, such as Idle, Seizing, Answered. In PPL files, a State is represented by a circle.

See Programmable Protocol Language.

A condition that, when met, drives a state machine from one state to another. A condition that drives a Component out of its current state by invoking an associated primitive.
