The PathBuilder S700 is a next-generation multiservice platform that provides
adaptation, concentration, and switching of a wide variety of traffic onto
high-speed ATM links. Delivering sophisticated data, voice and video adaptation,
and traffic management capabilities, the PathBuilder S700 WAN access switch is
an ideal platform both for service providers (to provision low-speed multiservice
services) and for enterprise users (to build converged networks).
The PathBuilder S700 provides the following key features:
Scalability—18 slots, with 14 slots for application modules, supporting a
n
maximum of 96 (rear access) or 112 (front access) T1 or E1 ports, 14 DS3 or E3
ports, or 14 OC3/STM-1 ports.
High ATM backplane capacity—3.2 Gbps
n
Supports proven technology—queuing, buffering, traffic shaping, traffic
n
policing, early packet discard, and multicasting. See "Key Features of the STX
Module" below for details.
Resiliency—supports load-sharing power supplies, hot-swappable common
n
components (MCPU and STX), and application modules; selected rear
redundant application modules are available; common component and
application module redundancy will be supported in subsequent releases.
Legacy module support—use existing PathBuilder S600 application modules
n
in the PathBuilder S700.
Rear cable access—rear access modules designed specifically for the
n
PathBuilder S700; available now for T1/E1 and DS3/E3 application modules.

Key Features of the STX Module

The STX module includes a switching fabric that provides sophisticated traffic
management, priority queuing, and multicasting. Once an application module
SARs its traffic into ATM cells, the STX receives the cells and performs address
lookup for switching, queuing, traffic shaping, traffic policing, early packet
discard, and multicasting.
