IP Server Interface (TN2312BP) - The IP Server Interface (IPSI) is the communication interface between the server and the Media Gateways (port networks). The IPSI is responsible for gateway control, and for tunneling call control messages back to the S8700.
One IPSI circuit pack is required per
The IPSI is located in the tone/clock slots, and provides the following functions:
●PKTINT packet bus interface
●Archangel TDM bus interface
●Tone/Clock functionality found on the TN2182B Tone/Clock circuit pack
●Ethernet interface for technician access
●Ethernet interface for connectivity to Services laptop computers
●Maintenance board interface for communication with the EPN maintenance board
Each IPSI typically controls up to five gateways by tunneling control messages over the center stage (TDM) network to the PNs that do not have IPSIs. For locations with high IP Telephone traffic, Avaya recommends a greater number of IPSI circuit packs.
An IPSI cannot be placed in:
●A PN that has a
●A remote PN that uses a DS1 converter
●A Survivable Remote Expansion Port Network (SREPN) The IPSI supports the following functions:
●Supports eight global Call Classification ports
●Supports network diagnostic capabilities
●Provides PN clock generation and synchronization for
●Provides PN tone generation
●Provides distributed PN packet interface
●Supports the download of IPSI firmware
●Provides serial number support for License File feature activation
