SYSTEM DESCRIPTION

PathBuilder S330/S310 Overview

PathBuilder S330

Features

This chapter describes the SuperStack® II PathBuilder® S330 and SuperStack® II PathBuilder PathBuilder S330 and PathBuilder S310 system speciﬁcations. It includes the following sections:

n PathBuilder S330/S310 Overview n Speciﬁcations n Options and Parts List

The PathBuilder S330 WAN access switch provides cost-effective T1/nxT1 or E1/nxE1 connections between local campus and enterprise networks via private leased line or public carrier ATM services so you can extend high-speed Internet access, Frame Relay, and ATM network service, as well as voice and video, out to your branch ofﬁces. Using the built-in ATM Forum standard-based inverse multiplexing capabilities, you can integrate voice, video, and high-speed data services over the same WAN link.

The PathBuilder S330 and PathBuilder S310 use basically the same hardware, with the PathBuilder S330 providing more interfaces. The following subsections describe the features of each unit in greater detail.

The PathBuilder S330 base platform offers the following features:

n T1/nxT1 ATM UNI or E1/nxE1 ATM UNI with up to four interfaces for

aggregated high-speed of 6Mbps WAN access. Each user-to-network interface (UNI) can be used alone or bundled into a group using the Inverse Multiplexing for ATM (IMA) standard, accommodating branch ofﬁce growth from a single T1/E1 (1.5/2 Mbps) bandwidth to four T1s/E1s (6/8 Mbps).

S310 WAN access switches (PathBuilder S330/S310), and lists

The PathBuilder S330 allows up to 70 msec of differential delay between T1s/E1s in a single IMA bundle. The unit also supports an automatic mechanism for removing failed lines from an IMA bundle, ensuring the resiliency required for your mission-critical applications.

n Multiple connections to Ethernet segments over ATM WAN and support of

bridging, including learning, aging, ﬁltering, and Spanning Tree, through the Ethernet module.

n Support of Frame Relay (service and network) interworking, ATM DXI, and

SDLC/HDLC pass-through, through the high-performance serial frame data interface.

4 CHAPTER 1: SYSTEM DESCRIPTION

n Choice of either single-mode or multi-mode OC3/STM-1 (separate units),

n Three expansion slots, allowing you to add other advanced features, such as

n 4x switch switching architecture, including four priority queues (three queues

The following optional modules are available for use with the PathBuilder S330:

n The four-port CBR module services trafﬁc generated by your existing PBXs,

through the OC3/STM-1 module. Single-mode enables higher-speed trunking if you have access to ﬁber WAN, while multi-mode is ideal for connecting high-speed servers, switches, or hubs equipped with multi-mode ﬁber connections.

channels, T1/E1 multiplexers, CSU/DSUs, and video conferencing devices. The CBR module consists of one V.35/RS-449 and three T1-DSX or E1 interfaces, which support both structured and unstructured services, in accordance with the ATM Forum’s Circuit Emulation Service (CES) speciﬁcations. The CBR module provides a smooth migration from legacy CBR service (PBX/voice/video) to ATM service. It also supports all relevant ATM and T1/E1 standards, ensuring easy integration of existing equipment into new ATM networks.

n The one-port Voice Compression module (VCM) is similar in function to the

CBR module, but it employs compression algorithms that allow more voice calls to be placed through the same bandwidth. The VCM’s T1-DSX/E1 interface connects to a PBX trunk, which may use CAS or CCS signaling. Its 24/31 DSO channels can carry individual voice, fax, modem, or data connections. You can also bundle multiple DSOs to provide connections for high-rate applications such as video conference or multiple-link PPP. For CCS, a DSO is used as an ISDN D-channel for carrying signal messages.

n The DS3/E3 module provides a DS3 or E3 interface, typically used for

terminating/accessing the public or private ATM WAN services. However, depending on your local applications, you can also use these modules for taking local DS3 or E3 ATM trafﬁc across the WAN.

Figure 1 shows the PathBuilder S330 with the optional CBR module installed in expansion slot 7, Voice Compression module in slot 8, and DS3/E3 UNI module in slot 9.

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.

S330 Only 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 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

S330 Only 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.

8 CHAPTER 1: SYSTEM DESCRIPTION

n Easily upgradable; no additional hardware required to move from the

PathBuilder S310 to the PathBuilder S330; update your system simply by purchasing a software upgrade.

n 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.

n Embedded management includes a full IP stack (Telnet, TFTP, and SNMP) and

ﬂash memory for sophisticated yet simple network management.

n Comprehensive feature support, including resiliency of nxT1/E1 IMA (S330

only) and redundant power for protection against power failure, ensures maximum application and network uptime.

n 3Com SuperStack II compliance provides common look and feel hardware and

integrated network management solutions.

n 3Com SuperStack II Redundant Power Supply (RPS).
