T HE S MART S WITCH R EMOTE A CCESS 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 work-
group or enterprise LAN, and remote access from home, field offices, and other remote locations
has become a necessity.
With the demand for remote LAN access, the remote device’s requirement for bandwidth has
exceeded the capabilities of traditional analog modems. High-speed digital dedicated lines can
certainly provide sufficient bandwidth for LAN interconnection. However, because 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 deployed by major telecommunications companies world-wide.
With ISDN services, the costs of LAN interconnection are based on actual usage — 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 SmartSwitch Remote Access Modules are versatile wide area networking products designed
for the SmartSwitch 9000. They provide SmartSwitch 9000 users with an integrated solution for
both LAN and WAN access. Their capabilities and performance match the requirements that high-
end network connectivity users expect. The 9W006 and 9W007 expand the SmartSwitch
architecture to provide ISDN and analog modem access. The analog modem access is provided via
digital modem technology, and can be supported over ISDN or channelized T1 lines.
The 9W006 and 9W007 SmartSwitch Remote Access Modules are installed directly into the
SmartSwitch 9000. They include fourflexible WAN interfacesproviding ISDN, analogmodem (via
digital modem), and T1/E1 or channelized T1 access. The 9W006 can support up to 96
simultaneous switched digital connections, and up to 48 simultaneous switched digital/analog
modem connections. The 9W007 can support up to 120 simultaneous switched digital connections,
and up to 60 simultaneous switched digital/analog modem connections.
THE SMARTSWITCH REMOTE ACCESS MODULE NETWORK
TheSmartSwitch RemoteAccess Module can be used with a mix of bridges,routers, hosts,PCs, and
workstations. These combinations provide internetworking capabilities that will allow devices to
carry out LAN-to-LAN applications such as telecommuting, electronic mail, multi-media
transmission, Imaging, and CAD. Devices “dial up” into a single system using a multi-line hunt
group to extend the capabilities offered by an enterprise LAN.

TELCO INTERFACES
The telco interfaces provide the 9W006 and 9W007 SmartSwitch Remote Access Modules with an
interface to telephone company-supplied ISDN PRI lines, or with unchannelized or channelized
T1/E1 lines.
Depending on the country where the PRI service is offered, each PRI line supports either the 23 or
30 64Kbps B-channels for data, plus one 64Kbps D-channel for signaling.

T HE S MART S WITCH R EMOTE A CCESS M ODULE
9W006 and 9W007 Functionality
The 9W006-220 (the 9W006 with two PRI interfaces and two digital modem interfaces) allows
channelized T1 service with robbed-bit signaling for users wanting to support analog modem calls
without concurrent ISDN support.
DIGITAL MODEM
The module’s digital modem capability allows analog modems to be intermixed with ISDN 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 B-
channelor channelized T1 SD0 data stream is then assigned to one of the digital modems. All of the
operations of a 56Kbps modem are performed 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 for modulation, and sent out the ISDN B-channel or T1 DS0 on the 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 compression protocols.
MANAGEMENT
The SmartSwitch Remote Access Module includes SFVRA-CFG, a management software with
flexible bandwidth management designed to keep performance up and cost down. Network
managers can configure a variety of parameters to control connections 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 more single remote locations, or through inverse multiplexing higher bandwidth
can be provided to users in multiples of 64Kbps.
Users can also configure the modules to sense data traffic needs and automatically initiate 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 management capabilities are also supported for centralized administration of
decentralized networks including the use of standards such as SNMP and Telnet.
The 9W006 and9W007 modules provide numerous network management features. Internally, Call
Detail Recording will log data to alocal 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

troubleshooting capabilities while the system is up and running. The modules also support SNMP
with both MIB II, private extensions, and a container MIB indicating the current configuration.
ADDITIONAL SOFTWARE
Cabletron also supplies two separate software products that are used in conjunction with the
SmartSwitch Remote Access Modules: SFVRA Configuration 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 network administrator can deploy and maintain an entire
CyberSWITCH network through a centrally located device. The network administrator can
generate each system’s configuration files separately, with the system’s view of the network, then
transfer the configuration files electronically to the system.
SFVRA-CONN offers state of the art policy-based management system for large central site dial-in
networks. This software provides a rich set of network configuration, 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 including multiple geographic sites) with audit/accounting capabilities.
UNIQUE SYSTEM FEATURES
The SmartSwitch Remote Access Module combines unique features that improve cost-
effectiveness, 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 authentication when a new
connection is established to the system.
• Bandwidth Agility
The system dynamically controls the bandwidth in use between itself and other PPP devices.
This is accomplished by establishing and disconnecting calls. The number of calls is limited
only by the types and number of lines available. The system monitors the connections for
utilization and will add and remove the connections based on user-configurable throughput
parameters. As network bandwidth requirements increase or decrease, the system will
automatically adjust the number of network connections. Thus, your network costs will reflect
the actual bandwidth being used.
• Data Compression
Allows the system to negotiate compression algorithms with another device on the network.
After successfully negotiating compression, data is compressed by the remote device and
transmitted to the system. The system decompresses 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 effect is to increase interconnect bandwidth by decreasing
transmission time. If negotiation for compression fails, data is transmitted uncompressed.

9W006 and 9W007 19
T HE S MART S WITCH R EMOTE A CCESS M ODULE
Unique System Features
• Dial Out Capability
The system will dial out to remote devices. This feature allows the system to accept user data
received on the Ethernet LAN or ISDN network and initiate a data connection to the remote
device specified in the user data. This allows devices on the local LAN to initiate connections
to networks connected to the system over the switched digital network. The system monitors
the connection for utilization and will remove 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 elements to support up to 48/60 analog and/or digital connections in
each dual-slot module.
• Dynamic Management
Provides a “real-time” management mechanism that allows many system parameters to be
changed without interrupting the current execution state of the system software. This feature
consists of a series of console commands that enable a user to display current system
parameters, change many parameters dynamically,and write changes to disk files so that they
remain permanent.
• High Speed Digital Connections
Thesystemsupports56Kbps and 64Kbpsconnectionsto remote locations. Thesedial-up digital
connections provide reliable high throughput connections for efficient data transfer for the
same cost as analog connections. If any remote devices connected to the system support multi-
link PPP, up to 32 parallel connections can be made at either 56Kbps or 64Kbps.
• Hot Swappable Modules
SmartSwitch Remote Access Modules are hot swappable. SFVRA Configuration Manager
(VRA-CFG) can retain the configuration and setup of the module and automatically download
the required information to a replacement module.
• Inverse Multiplexing
The modules provide inverse multiplexing for both ISDN and analog modem connections
supporting an aggregated bandwidth in multiples of 56/64Kbps.
• Layer 3 Switching Support
The SmartSwitch Remote Access Modules provide layer 3 switching support for IP, IPX, and
AppleTalk. Also provided is multiprotocol layer 2 switching.
•PacketCapture
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.
• Protocol 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.

•Security
Security is a key issue for all central site network managers and is a priority with the
SmartSwitch Remote Access Modules. The modules provide high level features that help
preventunauthorized or inadvertentaccesstocriticaldataandresources.Themodulessupport
extensive security levels including:
• PPP PAP and CHAP
• User name and password
• Calling Line ID (CLID)
• Ethernet Address
• User Authentication
• Device Authentication
• SecureFast Virtual Remote Access (SFVRA)
• Simultaneous Connections
The system supports simultaneous connections to multiple locations. These locations can
connect by using different channels on the same line, or they can connect on different lines. This
pooling of lines among many potential locations is more cost effective than alternative point-
to-point lines.
