Figure 17: SCC1 Media Gateway
Non-IPSI connected Media Gateway - Typically, one of every five Port Networks (PNs)
contains one or two IPSI circuit packs. The remaining PNs are referred to as non-IPSI
connected. Non-IPSI connected PNs get their control information from the servers through one
of the PNs that does contain an IPSI. Such control messages are “tunneled” through the
circuit-switched network. The system software controls this communication and allocation. The
software automatically routes the control messages through an appropriate IPSI. There is no
need to administer which IPSI controls the non-IPSI connected PNs. The system automatically
allocates those resources, and also compensates for any component failure.
Remote MCC1\SCC1 Media Gateways - The dedicated control network for an S8700 with
MCC1 or SCC1 Media Gateway can be extended to an IPSI in a remote media gateway. But for
cost effectiveness and straightforward installation, Avaya recommends that all of the
IPSI-connected media gateways be collocated with the S8700 and Ethernet switches. The
circuit-switched network dictates the available options.
Non-IPSI connected media gateways’ circuit-switched network can be extended through all the
options available with DEFINITY G3r. Center Stage Switch configurations can use fiber
extenders or DS1-Converter (DS1-C) facilities, allowing the media gateway separation to be
essentially limitless. When ATM-PNC is used, the media gateway separation is also essentially
limitless (see
ATM network
on page 60).
