FCC NOTICE

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

NOTE:

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment uses, generates, and can radiate radio frequency energy and if not installed in accordance with the operator’s manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause interference in which case the user will be required to correct the interference at his own expense.

WARNING:

party responsible for compliance could void the user’s authority to operate the equipment.

Changes or modiﬁcations made to this device which are not expressly approved by the

INDUSTRY CANADA NOTICE

The Industry Canada label identiﬁes certiﬁed equipment. This certiﬁcation means that the equipment meets certain telecommunications network protective, operational and safety requirements. The department does not guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certiﬁed connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certiﬁed equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power facility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

CAUTION:

Overview

1.3 OVERVIEW

The HSIM-W85 extends the functionality of certain Cabletron Systems platforms by providing an interface for Wide Area Network (WAN) DS1 services. The HSIM-W85 is a High Speed Interface Module (HSIM) used to provide WAN services using the SmartSwitch series of products as a platform. The HSIM-W85 has 8 physical DS1 interfaces, providing 8 separate logical DS1 connections. Eight separate T1 circuits can be conﬁgured, or the circuits can be combined into various Inverse Multiplexing (IMUX) groupings, up to a 12 Mbps full duplex data circuit within a Layer 2 IMUX group.

The typical conﬁguration is a head-end WAN aggregation point for up to 8 T1s into a single WAN physical interface. The HSIM-W85 is able to uplink any combination of single T1s or multiple T1 IMUX groups to the backbone. Refer to Appendix B for a diagram of a typical conﬁguration.

The HSIM-W85 has its own i960 HD microprocessor used to process data packets, provide simple conﬁguration, Inverse Multiplexer functionality, and statistics processing. The SmartSwitch host platform provides the required logical IP Host services. The HSIM-W85 is designed to be installed in any Cabletron Systems product that supports the High Speed Interface Module.

The HSIM-W85 operates in two modes:

•

Switching

•

IMUX

The ﬁrst mode, switching, is the default mode. The HSIM-W85 forwards data packets received by the host platform out through the logical DS1 interfaces. It also forwards packets received in the DS1 interfaces to or through the host. The default and only layer 2 WAN protocol used with the HSIM-W85 is raw HDLC.

NOTE

HSIM-W85 User’s Guide 1-3

The host platform may operate in 802.1D bridging, 802.1Q VLAN, or SecureFast mode.

Chapter 1:

Introduction

The second mode of operation is using Cabletron Systems Inverse Multiplexer (IMUX) functionality to aggregate multiple DS1 connections into single higher bandwidth WAN connections. To operate in this mode, the user conﬁgures the appropriate IMUX groups containing the DS1 connections.

Along with the built-in management features (Network Tools) described in Chapter 4, the HSIM-W85 can be managed using SNMP. Statistical data can be accessed via SNMP by referencing the interface group deﬁned in RFC 1213.

1.4 DATA FLOW IN THE HSIM-W85

The T1 data streams are terminated by T1 framers, which provide an HDLC bit stream to the HDLC controller. The controller receives data packets from each of the bit streams and places them in a memory subsystem. The on board CPU examines the packet and notiﬁes the host of its arrival. Finally, a Cabletron proprietary ASIC transfers the data to the host platform.

This process is followed in reverse when a packet is transmitted from the host platform out the T1 ports. The host platform notiﬁes the HSIM-W85 when a packet is coming and transfers the packet to the memory. The HDLC format is applied to the data, then the data is framed to a T1 format, and passed to the framer. The T1 data is transmitted out through the T1 interface.

1.5 FEATURES

The following are some of the highlights of the HSIM-W85 features:

•

Data Transfer Rates of 12 Mbps in full duplex, when running all eight T1s carrying continuous data trafﬁc of 64-byte packets or larger.

•

High-level Data Link Control (HDLC) protocol

•

T1 Inverse Multiplexing (IMUX)

•

WAN IP Priority Queuing functionality

•

DS1 Alarm Thresholds

•

SNMP support

1.5.1 Connectivity

The HSIM-W85 module supports WAN technology using eight live full duplex T1 connections.

The primary function of the HSIM-W85 is to provide LAN-to-WAN access. WAN physical connectivity will be supported through the use of a T1 interface. LAN-to-WAN connectivity will be supported through HDLC and T1 Inverse Multiplexing (IMUX).

The HSIM-W85 interoperates with those Cabletron Systems WAN products that support raw HDLC as the WAN protocol. This support is limited to the CyberSWITCH product line which supports HDLC:

•

CSX400 – Version 02.00.15 or higher

•

HSIM-W6 – Version 02.00.15 or higher

•

HSIM-W84 – Version 02.00.xx or higher

•

HSIM-W87 – SSR 2200 Version 04.05.06 or higher

1.5.2 HDLC

The High-level Data Link Control (HDLC) protocol is used in conjunction with the Inverse Multiplexing (IMUX) feature to conserve a user’s WAN bandwidth between two Cabletron Systems products, over a point-to-point connection. Cabletron Systems products such as the HSIM-W6, HSIM-W84, HSIM-W85, HSIM-W87, and CSX400 must be in use on both ends of the WAN link for these functions to work. The HDLC (RAW) protocol reduces the amount of overhead information that needs to be contained within each data packet to direct it to its destination. This decreased packet overhead provides the IMUX functions with more bandwidth to transfer user data.

HSIM-W85 User’s Guide 1-5

Chapter 1:

Introduction

1.5.3 Inverse Multiplexing (IMUX)

Cabletron Systems Inverse Multiplexing (IMUX) feature provides enhanced throughput for users by following this process:

•

The IMUX function evenly distributes a data packet stream from the LAN interface through multiple full T1 WAN interfaces on the HSIM-W85.

•

Data packet streams received by the WAN interfaces on the other end of the WAN links are then recombined, ordered, and transmitted to the LAN interface.

The IMUX function is conﬁgured using the Network Tools command, imux, described in Chapter 4.

NOTE

Cabletron Systems products that support Inverse Multiplexing (IMUX), such as the HSIM-W6, CSX400, HSIM-W84, HSIM-W85, and HSIM-W87, must exist on both ends of the WAN link for the IMUX function to work. All bridging and switching functions, such as 802.1D, SecureFast VLAN, and

802.1Q are able to run as normal on the host platform when using the IMUX function on the HSIM-W85.

1.5.4 Priority Queuing

WAN IP Priority Queuing is used to prioritize IP packets from a speciﬁed IP address. This prioritizing ensures that certain packets get through the network, such as management packets which are necessary to the operation of the network. It also ensures that routers that depend on protocols with tight timing, such as RIP, do not time out. The prioritized packets do not eliminate other trafﬁc on the network, but are held in a special queue, so that they are not discarded during oversubscribed traf ﬁc peaks. Priority Queuing can be enabled in management, using Network Tools. Refer to the wanpq command in the

Management

chapter.
