ESCRIPTION
Dynamic bandwidth allocation (DBA) for structured voice and structured data
CBR ports. When DBA is implemented on a CBR port configured for structured
voice, stored signaling bits are checked and bandwidth is released when an
on-hook (idle) condition is detected. When DBA is implemented on a CBR port
configured for structured data, stored data bits are checked and bandwidth is
released when and idle code is detected.
RS-366-based video dial feature, supporting point-to-point and multi-point
video conferencing
Voice compression, supporting voice activity detection, modem detection,
DTMF relay, and G.729A, G.726, and G.711 compression algorithms.
DS3/E3 UNI interface
Local management via a VT100 terminal (or a PC emulating one) connected
directly to the PathBuilder S330/S310 switch, or through a Telnet session.
Software downloading via TFTP, FTP, or direct via RS-232
Built-in, menu-driven software for configuring modules, ports, virtual circuits,
and bridges; setting loopbacks; and collecting and displaying alarms.
The PathBuilder S330/S310 switches provide the following key benefits:
Complete integration into existing application environments by supporting
legacy data, video, and voice applications, thereby avoiding costly forklift
upgrades.
Video dial feature supports point-to-point and multi-point dialed video
conferencing over ATM networks, including:
RS-366 video dial
Static call routing for all destinations
Ideal for video equipment such as H320
Dynamic bandwidth allocation at both the V.35/RS-366 port and the
T1-DSX/E1 port on the CBR module
Video session dialed through SNMP interface via Telnet and RS-232
Simulation of a switched ISDN network over an ATM network
Standards-based IMA implementation; the PathBuilder S330 offers T1/nxT1
and E1/nxE1 ATM access with up to four T1/E1 connections (eight connections
when you install the optional 4-port IMA expansion card), allowing you to scale
up WAN bandwidth as your traffic increases. Each user-to-network interface
(UNI) can be used alone or bundled into a group, providing up to 6/8 Mbps
aggregated WAN access speed.
Easily upgradable; no additional hardware required to move from the
PathBuilder S310 switch to the PathBuilder S330 switch; update your system
simply by purchasing a software upgrade.
A sophisticated traffic management system allows management of a mix of
applications simultaneously, with features such as deep buffers, traffic shaping,
QoS (Quality of Service), and early packet discard, to give you the most
effective wide-area ATM bandwidth use and ensure applications integrity.
Embedded management includes a full IP stack (Telnet, TFTP, and SNMP) and
flash memory for sophisticated yet simple network management.
