1 SYSTEM DESCRIPTION This chapter describes the SuperStack® II PathBuilder® S330 and SuperStack® II PathBuilder® S310 WAN access switches (PathBuilder S330/S310), and lists PathBuilder S330 and PathBuilder S310 system specifications. It includes the following sections: n PathBuilder S330/S310 Overview n Specifications n Options and Parts List PathBuilder S330/S310 Overview 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. PathBuilder S330 Features 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). 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.
