HE SMARTSWITCH REMOTE ACCESS

M

ODULE

Because of the strong personal computer presence in the business environment, a move to
graphical user interfaces, and the need to make the best use of available resources, there is a
growing demand for high speed LAN access for remote devices. PC users need to be part of a work­group or ente rprise LAN, and remote access from home , field offices, and other remote locations
has become a necessity.

With the de mand for remote LAN access, the remote device’s requirem e nt for bandwidth has
exceeded the capabilities of traditional analog modems. High-speed digital dedicated lines can
certainly provide su fficie nt band wi dt h for LAN inter con n ect ion . How ever , beca use of the high
monthly charges associated with dedicated services, the costs are prohibitive for individual users.

New forms of networking are now possible and affordable using the Integrated Services Digital
Network (ISDN) . ISDN is being deploy ed by majo r teleco mmunications companie s world- w ide.

With ISDN ser vices, t he costs o f LAN inte rconnect ion are b ased on ac tual usa ge — the user gets the
bandwidth of dedicated digital service at dial-up prices.

Our products offer internetworking solutions for small businesses as well as large corporations.

The SmartS witch Remote Access Modules are versatile wide area networking products design e d
for the SmartSwitch 9000. They provide SmartSwitch 9000 user s with an integrated solution for
both LAN and WAN access. Their capabilities and performance match the requirements that high­end network connectivit y users expect. The 9W006 and 9W007 expand the SmartSwitch
archit e ct ure t o p r ovid e I SDN an d ana lo g mode m ac ces s. Th e a na log mode m ac ce ss i s p ro vid ed v ia
digital modem techno lo gy, and can b e suppo rte d over ISD N or channe li zed T1 lines.

The 9W006 and 9W007 SmartSwitc h Remote Access Modules are installed directly in to the
SmartSwitch 9000. They include four flexible WAN interfaces provid ing ISDN, analog modem (via
digital modem), and T1/E1 or channelized T1 access. The 9W006 can support up to 96
simultaneous swit ched digital connection s, and up to 48 simultaneous switched digital/analog
modem co nnec tions. T he 9W007 can su pport up to 120 si mul ta neous swi tched d igit al conne cti ons,
and up to 60 simultaneous switched digital/analog modem connecti ons.

THE SMARTSWITCH REMOTE ACCESS MODULE NETWORK

The SmartS witc h Remote Acces s Modul e can b e used with a mix of br idges, r outers, hos ts, PCs, and
workstation s. These com bina t ions pro vi de inter netwo rk ing cap ab ilitie s that will allo w dev ices to

THE S

MARTSWITCH REMOTE ACCESS MODULE

9W006 and 9W007 Functionality

The 9W006-220 (the 9W006 with two PRI interfaces and two digital modem interfaces) allows
channelize d T1 ser vic e with rob bed -bit si gn ali ng f or use rs wan tin g t o suppor t anal og mod em ca lls
without concurrent ISDN support.

DIGITAL MODEM

The module’s digi tal modem ca pa bilit y allow s analo g mode m s to be intermix e d with ISD N as
required to best fit specific user situations.

Up to sixty 56Kbps digital modem connections are supported. The digital modem is connected
internally to the telco interface (ISDN PRI or channelized T1) eliminating the need for separate
analog telco connections.

When the modules identify that a call is coming from an analog modem, the associated ISDN B­channel or channelized T1 SD0 data st ream is th en assign ed to one of th e digital mod ems. A ll of the
operati ons of a 56Kbps modem are pe rf ormed just as if the call had gone to an analog modem
through an analog phone line (although at the higher speeds available with digital modem
technology).

Similarly, data coming into the modules (typically from the LAN) is converted to Async-PPP, sent
to the digital modem fo r modulation, and sent ou t the ISDN B-ch annel or T1 DS0 on th e telco line.

The K56flex digital modem protocol provides automatic rate detection/negotiation such that lower
baud rates are fully supported. The digital modem also supports MNP4 and V.42 error control
protocols, and MNP5 and V.42bis data compressi on protocols.

MANAGEMENT

The SmartS witch Remote Access Module inc ludes SFVRA-CFG, a mana ge me nt software with
flexible bandwidth management designed to keep performance up and cost down. Network
manager s can configure a varie ty of par a me ters to control co nn e ctions being established and
terminated including restrictions by packet type, time of day, and maximum calls per day.

The management capabilities included allow great flexibility. Each B channel can be used to
connect to one or mo re si ngle remo te lo cat i ons, or thr oug h inv ers e mu lti pl ex ing h igh er band wid th
can be provided to users in multiples of 64Kbps.

Users ca n als o config u re the module s to se nse data traffic nee ds and au to m a ti cally in itiate or
terminate calls. This provides bandwidth-on-demand resulting in high performance with minimal
associated cost. The management of these calls is extremely important for minimizing ISDN phone
charges.

Remote managem ent capab ilitie s are also suppo rted for centraliz ed adm inis tration of
dece ntralize d n e tw orks incl uding th e us e of sta ndards such as SN MP and Tel n e t.

The 9W006 and 9W007 modules provide numero us network management features . Internally , Call
Detail Recording will log data to a local file. Using Syslog users can capture essential data regarding
remote users connection time. Also supported is Telnet with password, host and terminal server as
well as tftp for the ability to upload and download log files. CDR files provide tracking and

Cabletron also supplies two separate software products that are used in conjunction with the
SmartSwitch Remote Access Modules: SFVRA Config u ration Manager (SFVRA-CFG ) and SFVRA
Connection Manager (SFVRA-CONN).

SFVRA-CFG provides a GUI interface for configuring the SmartSwitch Remote Access Module.
Through the SFVRA-CFG, the netw ork administrator can deploy and maintain an entire
CyberS WI T CH network through a cen tr al l y located devi ce . The net work adm in is trator can

generate each system’s configuration files separately, with the system’s view of the network, then
transfe r th e configuration files elec tronically to the system.

SFVRA-CONN offe rs st at e of th e a rt poli cy-base d ma nagem ent sy st em fo r lar ge ce ntr al si te dial-i n
networks. This sof tware provides a rich set of network config uration, management, and reporting
capabilities. The functionality of SFVRA-CONN software includes policy-based connectivity
management, virtual networking that spans multiple modules (including multiple SmartSwitch
9000 chassis, and even includ ing multi p l e geo graph i c si tes) with audit/account i ng ca pabi lities.

UNIQUE SYSTEM FEATURES

The SmartS witch Remote Access Module co mbines unique fe atures that improve cost­effectiveness, reliability, and performance for wide area network connections to remote devices.
These features include:

• Authentication Servers
Provide a central database for networks with more than one SmartSwitch Remote Access
Module. The central database consists of manageable, informational data (referred to as the
Device List or Device Table). This data is accessed and used for authentica tion when a new
connection is estab lished to the system.

• Bandwidth Agility
The system dynamically controls the bandwidth in use between itself and other PPP devices.
This is accomplished by estab lishing a nd dis c onn ecting calls . The num be r of calls is limited
only by the types and number of lines available. The system monitors the connections for
utilization and will add an d remove the connec tions based on use r- configurable throughput
parameters. As network ba ndw id th requirem ent s increa se or decrea se, the system will
automati cally adju st th e nu mber of ne twork con nect ion s. Thus, your n et work costs w il l ref lec t
the actual bandwidth being used.

• Data Compression
Allows the system to negotiate compression algorithms with another device on the network.
After successfully negotiating com p re ssion, data is compressed by the remote device and
transmi tte d to the system. The system deco mp resses the data, processes the information
contained in the user data, and forwards the data as required. The system can receive data
coming over a WAN or a LAN, and compress the data before transmitting it to another device
on the network. The net ef fect is to i ncrease int erconnect bandwidth by decrea sing
transmi ssion time. If negotiati on for compre ssion fails, data is transmitted uncomp ressed.

Unique System Features

• Dial Out Capability
The system will dial out to remo te dev ices . Th is featur e allows the sy st em to accep t user data
receiv e d on the Ethernet LA N or I S DN network and initiate a data connectio n to the remote
device specified in the user data. This allows devices on the local LAN to initiate connections
to networks connected to the syste m over the switched digital network . Th e system monitors
the connection for utilization and will rem ove the connection when it becomes idle.

• Digital Modem
The system becomes an analog modem pool through its digital modem option. The system
supports analog modem calls for high density channelized T1 lines using Robbed-Bit
Signaling. It also supports 56Kbps digital modem technology (K56flex) with auto negotiation
to automatically adapt to various modem speeds. The digital modem adapter consists of both
hardware and software ele ments to support up to 48/60 analog and/or digital connections in
each dua l- s lo t mo dule.

• Dynamic Management
Provides a “real- time” manageme nt mechan ism that allows many sys t e m p a rameters to be
changed with out interrupti ng the current execution state of the system software. Th is feature
consists of a series of console comman ds that enable a user to displa y current system
paramet ers , c ha ng e man y par ame ter s d yna mica lly , and wri t e cha ng es t o d isk f il es s o th at the y
remain permanent.

• High Speed Digital Connections
The system supp orts 56Kbps and 64Kbps co nnections to remote locatio ns. These dial- up digital
connections provide re liable high throughpu t connections for efficient data transfer for the
same cost as analog connections. If any r e mote devices conn e cted to the system support multi­link PPP, up to 32 parallel connections can be made at either 56Kbps or 64Kbps.

• Hot Swappable Modules
SmartSwitch Remote Access Modules are hot swapp able. SFVRA Co nfiguration Manager
(VRA-CFG) can retai n the confi guration and setup of the module and auto maticall y download
the required information to a replacement module.

• Inverse Multiplexing
The modules provide inv ers e mult iple xin g for bo th ISDN a nd ana lo g mo dem con nect ion s
supporting an aggregated bandwidth in multi pl e s of 56/ 64K bps.

• Layer 3 Switching Support
The SmartS witch Remote Access Modules provide layer 3 switching support for IP, IPX, and
AppleTalk. Also provided is multiprotocol layer 2 switching.

•Packet Capture
In order to monitor incoming LAN data, the SmartSwitch Remote Access Module packet
capture feature will allow you to capture, display, save, and load bridged or routed data
packets.

• Proto col Discrimination
It is possible for multiple types of remote devices to use the same line. The system can
determine the device type and the protocol encapsulation used by remote devices.

NETWORK INTERFACE OVERVIEW

The network i nterface is th e p hysical conn e ction of the SmartSwitch Remote Access Module to a
data network . Fo r example , the Ether net res ou rce in th e system provi des a net work inter face to an
Ethernet LAN. The ISDN lines in the syste m provide network interfaces to multi ple remote
networks. Because of their sw itched nature, the IS DN lines provide virtual network interfaces. That
is, the same physical ISDN line can actually connect to different remote networks by dialing a
different phone number.

The SmartSwitch Remote Access Module provides a set of network interfaces that give you a wide
range of flexibility. The network interfaces provided by the system are:

• LAN IP Network Interface

• LAN IPX Network Interface

• WAN IP Network Interface

• WAN RLAN IP Network Interface

• WAN RLAN IPX Network Interface

• WAN (UnNumbered) Network Interface

The variety of ne twork interfaces allows the instal lation of a wide range of de vices at remote sites.
