Supports arbitrary combinations of multiple DS0 channels, allowing transport and switching of diverse media types. Subrate switching, down to 8 kbps, multiplies channel capacities up to 8x, efficiently handling slow speed data links and compressed voice. SCSA back plane provides low latency switching of TDM data, offloading the VME bus from media stream traffic. On board microprocessor with Real Time OS handles low level board control, simplifying host software tasks and improving call event response time. LAP B, LAP D, Q.921 and Q.931 ISDN and X.25 run on embedded CPU, eliminating additional hardware.
Software is downloadable to flash memory for simplified upgrades and field support.
Dual 100 base T Ethernet ports support HA and remote server configurations. Access to raw signaling data provides flexibility in customizing systems. VME 64x allows mission critical systems to continue operation during maintenance and upgrade procedures. Span and board status displays clearly show current board status. Host-based API and driver for VxWorks, Windows NT, and Solaris operating systems simplifies system integration.
