SYSTEM DESCRIPTION

This chapter provides a brief overview of ATM (Asynchronous Transfer Mode) technology, describes the PathBuilder S600), and lists PathBuilder S600 system speciﬁcations. It includes the following sections:

n ATM Overview n PathBuilder S600 with STX Overview n Speciﬁcations n Options and Parts List

S600 WAN Access Switch (PathBuilder

ATM Overview ATM provides the means of simultaneously transferring a wide variety of services

with different protocols and bandwidth requirements such as voice, packet data, and video between end users or user networks. It does so by segmenting the input data streams into 53 byte cells, assigning the cells to virtual circuits set up in the ATM network, multiplexing the cells for transmission according to the bandwidth requirements of the individual data streams, and reassembling the cells into the original data streams at the receiving end.

For more detail about how to apply the PathBuilder S600 to provide ATM WAN access, see “Application Overview” in Chapter 4.

Virtual Circuits ATM networks are organized into virtual circuits or logical duplex paths between

two ATM unit ports, as shown in Figure 1.

20 CHAPTER 1: SYSTEM DESCRIPTION

Each transmission direction in a virtual circuit is referred to as a virtual channel. Virtual channels are then grouped into virtual paths between two ports. The channels and paths are assigned numbers: VPIs (Virtual Path Indicators) and VCIs (Virtual Channel Indicators). Each ATM cell (a ﬁxed-length unit of data over ATM) is assigned to a virtual circuit by including the circuit's VPI/VCI in the cell's header. This is then used to steer the cell through an ATM unit and the ATM network.

PathBuilder S600 with STX Overview

PathBuilder S600 STX

Architecture

The PathBuilder S600 WAN access switch with Super Transport eXchange (STX) provides enhanced switching and trafﬁc management capabilities. It is designed to concentrate, aggregate, and switch local ATM and legacy trafﬁc over ATM wide-area services for affordable ATM services access.

The PathBuilder S600 with STX requires software Release 2.0 or higher.

The modular architecture of the PathBuilder S600 with STX is designed to accommodate a wide range of interfaces and support a comprehensive set of applications. The core component of the unit is a 1.6 Gbps cell bus backplane where all trafﬁc is carried in the form of ATM cells. The PathBuilder S600 with STX accommodates up to two power supplies (AC110/220 VAC and DC-48 VDC) in a redundant conﬁguration.

The overall design philosophy of the PathBuilder S600 with STX is to facilitate the transfer of cells on and off the bus backplane with enhanced trafﬁc management and switching capabilities. All packet to cell segmentation and reassembly (SAR) functions are performed on each of the application modules (Ethernet, Frame Relay, and CBR), thereby ensuring efﬁcient cell transfer through the system, (See Figure 2.) Additional SAR power is added each time a non-ATM interface module is added.

Figure 2 PathBuilder S600 with STX Cell Bus Architecture

Because the STX module allows any-to-any port switching, there is no distinction between port and trunk modules for the PathBuilder S600 with STX. Thus, the slot assignments are as follows:

PathBuilder S600 with STX Overview 21

n Slot 1 contains the Management CPU (MCPU). This slot is permanently

allocated. The MCPU manages the conﬁguration database, network management (via Text User Interface and SNMP) and software download capabilities.

n Slot 2 contains the STX Module. This slot is permanently allocated. n Slots 3-6 contain the application modules.

All modules are front-loading with a direct cable attachment on the front of each card, and each module incorporates an RISC based processor (30 MIPs each) for processing packets/cells, communication information, and statistics. The unit accommodates up to 2 power supplies (AC 110/220 VAC & DC -48 VDC) in a redundant conﬁguration.

The S600 supports the following ATM and application modules:

n DS3 UNI module n E3 UNI module n OC3/STM-1 UNI module n DS1 UNI with Inverse Multiplexing for ATM (IMA)

Key Features of the STX

Module

n E1 UNI with Inverse Multiplexing for ATM (IMA) n Dual Ethernet module n CBR (Constant Bit Rate) DSX module (4 port or 8 port) n CBR (Constant Bit Rate) E1 module (4 port or 8 port) n QSIM (Quad Serial Interface Module) (QSIM) - V.35/RS422/EIA530/X.21 n HSIM (HSSI Serial Interface Module) n FAM (Frame Access Module) - DS1

The STX module includes a switching matrix that provides sophisticated trafﬁc management, priority queuing, and multicasting. Once an application module SARs its trafﬁc into ATM cells, the STX receives the cells and performs address lookup for switching, queuing, trafﬁc shaping, trafﬁc policing, early packet discard, and multicasting. The STX module provides the following functions to the PathBuilder S600:

n Provides any-to-any port switching. n Supports Deep buffers (192,000 cell buffers per module) for queuing. n Introduces virtual interfaces (VIs)—logical UNI ports—and supports up to 24 VIs

per application module and up to 2 VIs for the MCPU module. The VIs provide trafﬁc shaping proﬁles.

n Provides priority queuing in which each VI can be assigned to speciﬁc VCs

n Supports per VC and/or per VP trafﬁc shaping. n Supports per VC trafﬁc policing. n Supports multicasting (up to 256 connections with 32 leaves). n Includes a Bits timing clock. n Supports per VC statistics. n Allows a total of 8,000 connections per unit.

which then can be allocated to one of 4 queues.

28 CHAPTER 1: SYSTEM DESCRIPTION

INSTALLATION

This chapter tells you how to mechanically and electrically install the PathBuilder® S600 WAN Access Switch (PathBuilder S600) in your network. It contains the following sections:

n Receiving and Inspecting the PathBuilder S600 n Installation Overview n Step 1: Install the Shelf in the Rack n Step 2: Connect AC or DC Power n Step 3: (If needed) Install Additional Modules in the Shelf n Step 4: Connect I/O Cabling and Wiring n Step 5: Connect a Management Terminal

Before using the chapter for an actual installation, read through it at least once to familiarize yourself with the overall process.

Receiving and Inspecting the PathBuilder S600

When you receive the PathBuilder S600, unpack it and inspect the unit for any damage that might have occurred during shipment. Inventory the equipment against the shipping notice.

Save the boxes and packing materials in the event there is damage or anything needs to be reshipped at a future date. If anything is damaged or missing, contact the shipper and 3Com immediately.

CAUTION: Many of the integrated circuits on the modules are sensitive to static electricity. Do not remove the plug-in modules from their shelves without wearing a properly grounded, antistatic, wrist strap.

Installation Overview Figure 3 summarizes the overall installation procedure for the PathBuilder S600.

For details about each step in the overall procedure, see the following sections.

30 CHAPTER 2: INSTALLATION

Figure 3 General Installation Procedure

Prepare the Site:

Verify Clearances Around the Shelf Site

Fabricate and Run Cabling and Wiring Prepare AC or DC Power Run (Install Fuse and Alarm Panel)

Step 1

Install the Shelf in the Rack

Step 2

Step 3

Connect AC or DC Power

(If needed) Install Additional Modules in the Shelf and Monitor Front-Panel LEDs

Connect I/O Cabling and Wiring:

Step 4

Network Ports Trunk Ports Local Terminal Office Alarms BITS clock

Step 5

Connect a VT100 Terminal for

Local Management Access

Site Requirements n Be within the maximum distances to the port and trunk connections, as well as

the NMS terminal

n Have interconnect cabling and wiring ready and labeled n Have a dedicated source of switched and fused AC power.

Step 1: Install the Shelf in the Rack

n Provide clearance for making all connections and performing maintenance.

In a normal rack mount conﬁguration the PathBuilder S600 shelf is 8.75" x 17.25" x 11" including cables. Since the equipment is cooled with two internal fans, clearance at the top is not needed. Convection cooled equipment should not be mounted directly under the shelf but a least one rack unit below it. See Figure 4 for details. If the PathBuilder S600 is mounted in an enclosure, plan on enough clearance at the front for cable and wiring service loops.

CAUTION: Many of the integrated circuits on the modules are sensitive to static electricity. Do not handle the plug-in modules without wearing a properly grounded, antistatic, wrist strap. When removing the modules from the shelf, place them printed-circuit side down on a nonconducting, static-free, ﬂat surface.
