PathBuilder S330/S310 Overview 7 Application Support S330 Only S330 Only S330 Only The PathBuilder S330/S310 supports the following applications: n 4 x T1/E1 IMA function on the trunk, up to four trunk groups (individual T1s/E1s) n Single T1/E1 for PathBuilder S310 n OC3/STM-1 UNI port interface (multi-mode or single-mode fiber), compliant with ATM Forum's UNI 3.1, ANSI T1.105 n Ethernet interface and bridge function, bridged RFC 1483 and Spanning Tree n 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 n Structured and unstructured CBR T1-DSX/E1 and V.35/RS-449/RS-530/X.21 interface n 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 n RS-366-based video dial feature, supporting point-to-point and multi-point video conferencing n Voice compression, supporting voice activity detection, fax relay, DTMF relay, and G.729A, G.726, and G.711 compression algorithms. n DS3/E3 UNI interface n Local management via a VT100 terminal (or a PC emulating one) connected directly to the PathBuilder S330/S310, or through a Telnet session. n Software downloading via TFTP, FTP, or direct via RS232 n Built-in, menu-driven software for configuring modules, ports, virtual circuits, and bridges; setting loopbacks; and collecting and displaying alarms. Key Benefits S330 Only The PathBuilder S330/S310 provides the following key benefits: n Complete integration into existing application environments by supporting legacy data, video, and voice applications, thereby avoiding costly forklift upgrades. n Video dial feature supports point-to-point and multi-point dialed video conferencing over ATM networks, including: n RS-366 video dial n Static call routing for all destinations n Ideal for video equipment such as H320 n Dynamic bandwidth allocation at both the V.35/RS-366 port and the T1-DSX/E1 port on the CBR module n Video session dialed through SNMP interface via Telnet and RS232 n Simulation of a switched ISDN network over an ATM network n 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.
