Prior to this feature, the communication between the ISDN Series 3 card and the CSP Matrix 2000 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 CSP Matrix 2000 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 CSP Matrix 2000 card. Communication over the HDLC bus will continue to be supported. Licensing of this feature is not required.
FR1146 - State Syncing on PPL Event Request for ANM
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:
• L3P CIC component of ANSI or ITU
• L3P BT IUP component for BT IUP
