PathBuilder S330/S310 Overview 7

Application Support The PathBuilder S330/S310 supports the following applications:

S330 Only ■ 4 x T1/E1 IMA function on the trunk, up to four trunk groups (individual T1s/E1s)

■Single T1/E1 for PathBuilder S310

S330 Only ■ OC3/STM-1 UNI port interface (multi-mode or single-mode fiber), compliant with ATM Forum’s UNI 3.1, ANSI T1.105

■Ethernet interface and bridge function, bridged RFC 1483 and Spanning Tree

■Serial V.35/RS-449/RS-530/X.21 interface frame module, including DXI protocol, basic frame relay protocol (DLCI to VP/VC conversion), and transparent HDLC mode of operation

■Structured and unstructured CBR T1-DSX/E1 and V.35/RS-449/RS-530/X.21 interface

■Dynamic bandwidth allocation for structured voice CBR ports—stored signaling bits are checked and bandwidth is released when an on-hook (idle) condition is detected

■RS-366-based video dial feature, supporting point-to-point and multi-point video conferencing

■Voice compression, supporting voice activity detection, fax relay, DTMF relay, and G.729A, G.726, and G.711 compression algorithms.

S330 Only ■ DS3/E3 UNI interface

■Local management via a VT100 terminal (or a PC emulating one) connected directly to the PathBuilder S330/S310, or through a Telnet session.

■Software downloading via TFTP, FTP, or direct via RS232

■Built-in, menu-driven software for configuring modules, ports, virtual circuits, and bridges; setting loopbacks; and collecting and displaying alarms.

Key Benefits The PathBuilder S330/S310 provides 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 RS232

■Simulation of a switched ISDN network over an ATM network

S330 Only ■ Standards-based IMA implementation; the PathBuilder S330 offers T1/nxT1 and E1/nxE1 ATM access with up to four T1/E1 connections, 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.
