Plexus 9000 Softswitch-Based Switching System Overview
Telica, Inc.'s Plexus 9000 is a very high-capacity carrier-grade switching
system that supports both circuit and packet switching. It is a softswitch-
based voice and data-switching product, which includes a media gateway,
media gateway controller, and signaling gateway to provide Class 4/5
switching and features for the PSTN as well as ATM and IP networks – all
in an open, distributed softswitch model or an integrated, single-chassis
solution.
The Plexus 9000 normalizes a carrier's layer two switching and transport
requirements regardless of content or access method. The switch has
integrated signaling and call control capabilities that support various
protocols including SS7, ISDN, ATM, IP and CAS. As a true Central
Office (CO) switching system, the Plexus 9000 complies with Network
Equipment Building System (NEBS) requirements, including a fault-
tolerant architecture that provides carrier-grade reliability against hardware
and software faults. With its redundant 15 Gb/s switching fabric, the
Plexus 9000 easily handles the challenging and dynamic mixture of TDM
and packet traffic.
The Plexus 9000 architecture offers a unique combination of redundancy,
capacity, size, economy and manageability with integrated signaling,
switching, and termination functions.
