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 carry out LAN-to-LAN ap plicat ions such as teleco mmut ing, electron ic mail, mult i-m edia transmissi on, Imaging, and CAD. Devices “dial up” in to a single system using a multi-line hunt group to extend the capabilit ies o ffere d by an enter prise LAN .

TELCO INTERFACES
The telco interf aces provide the 9W006 and 9W007 SmartSwitc h 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 li ne supports either the 23 or 30 64Kbps B-channels for data, plus on e 64Kbps D-channel for signaling.

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
Page 18

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 configur ation.
ADDITIONAL SOFTWARE
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.

•Security Security is a key issue for all central site network mana gers and is a priority with the SmartSwitch Remote Access Modules. The modules provide high level features that help prevent unauthorized or i nadvertent ac cess to criti cal data and r esources. The modules suppor t extensive security levels includ ing:
• PPP PAP and CHAP
• User na me a nd p a ss w or d
• Calling Line ID (CLID)
• Ethernet Address
• User Authentication
• Device Authentication
• SecureFast Virtual Remote Access (SFVRA)
• Simultaneous Connections The system supp orts simultaneo u s connectio n s to multiple l o ca t i ons. Thes e lo ca tions can connect by using different channels on the same line, or they can connect on different lines. This pooling of lines among many poten tial loc ations is more cost effective than alternative point­to-point lines.
INTEROPERABILITY OVERVIEW

• MAC Laye r Br idge s
•IP Host Devices
• IP Router Devices
• IPX Routers
• AppleTalk Routers
MAC layer bridge s connec t to the syste m using the HD LC bridge encap sula tion line p rotoc ol . These devi ces send transpar ently bridged E therne t frames to the sy stem. MAC layer br idges do not process ne twork layer protocols. The y forward all packets based on source and destinati on MAC addresses.
IP Host devices are single workstations or PCs that co nne ct to the system at the IP network layer. These devices use either the RFC1294 based protocol or PPP to communicate with the system.
IP router devices are single devices that represent many ot her IP hosts and ro uters to the syste m. They must use the CHAP or PAP protocol to identif y themselves to the system. IP routers usually provide IP network address information at connection time (and use PPP to send user data to the system).
IPX routers are single devices that perform network layer tasks (addressing, routing, and switchin g) to move packet s from one location on the network to anot her. IPX ro u te rs use the Internetwork Packet Exchange (IPX) protocol, typical of the NetWare environment.
AppleTalk routers route AppleTalk datagrams based on address information. They support the following protocols: RTMP, NBP, and ZIP.
SECURITY OVERVIEW
The system provides se veral options for valid ating remote devices and for managing network security. The security options available are dependen t on the remote device type, type of access , and the level of security required.

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. As illustrated below, you can simultaneously choose bridges, routers, or host devices based on the speci f ic re mote si te re qu i r e ments.

MODULE INTERFACES
The SmartSwitch Remote Access Module includes the possibility of four flexible WAN interfaces providing ISDN, analog modem (via digital modem), and T1/E1 or channelized T1 access. As described earlier, depending on the model, the module may have one of the following interface configurations:
•four PRI interfaces
•two PRI interfaces
• two PRI interfaces and two digital modems
PRI interfaces provide the module with an i nterface to telephone c ompany-supplied ISDN Primary Rate Interface (PRI) lines, or with unchannelized or channelized T1/E1 lines. Each PRI interface supports up to 23 B channels for data and a 64Kbps si g naling D channel (for countries using T1 lines), or up to 30 B channels for data and a 64 Kbps signaling D channel (for countries using E1 lines). The module uses the B channels for switched connections to carry device data. PRI interfaces have an external port for connecting to the Telco interface.
Digital modem interfaces allow the SmartSwitc h Remote Access Module to recei ve calls from asynchronous PPP remote devices connected by modem. Each digital modem interface supports up to 24 56Kbps modem connections (for countries using T1 lin e s), or up to 30 56Kbps mod e m connections (for countries using E1 lines). Digital modem interfaces are connected internally to the PRI interface eliminating the need for separate analog telco connections.

ONFIGURATION OVERVIEW
OVERVIEW
We provide the following configurati on tools to set up and/or alter your configuration:
• SFVRA Configuration Manager, the graphical interface utility for basic to intermediate configurations
• CFGEDIT, the configuration utili ty for more comp lex configur ations
• Manage Mode, the dynamic management utility
SFVRA Configuration Manager (SFVRA-CFG) is a fast and easy way to configure basic features for your syst em. How ever , SFVRA-C FG is N OT dyn amic . T his me ans that a fte r th e con fi gurat ion fil es are transf err ed, SFVRA -CFG in te rrup ts nor mal sy stem operati on i n or der to impl ement t he f iles. It is also important to note that downloading these configu ration files does not update the system’s existing configuration files, it overwrites them.
The follo wing is a list of some of th e major features that cannot be con f igured by SFVRA-CFG:
• AppleTalk Remote LAN port
• Bridge filters
•DHCP
• File attributes configuration
•Frame Relay
• IP filters
• IPX static routes and services
• Off-node authentication databases
• TFTP configuration
•X.25
For a more complex configuration, CFGEDIT is a comprehensive utility you may wish to use to configure advanced features for your system. CFGEDIT is also NOT dynamic. This means you will have to interrupt normal system operations in order to update configurat ion files. (You may do so by either rebooting, or issuing the
restart
command).
WARNING:
If you use CFGEDIT to make configuration change s you will no longer be able to use SFVRA-CFG.
Manage Mode provides a real-time management mechanism that allows you to change the config uration , withou t inte rrupti ng the curren t exec ution s tate of the s ystem so ftwa re. Bu t, beca use it is dynamic, Manage Mode does have its limitations. So, when making configuration changes, you usually need to use a combination of both Manage Mode and CFGEDIT.
WARNING:
If you use Manage Mode to make configuration changes you will no longer be able to use SFVRA-CFG.
You may onl y have one CFGED IT or Dyn amic Mana gement sessio n activ e at a ti me per s ystem. F or example, if a user is making changes directly to the system using Dynamic Management, and then a second person at a different location using Telnet attempts changes, access will be denied to the second person. However , if you have an active CFGEDIT or Dynami c Manage m ent session and

you use SFVRA-CFG to d ownl oad con fig urati on fil es, th e fi les wi ll be over writ ten and the sy stem will reboot. The CFGEDIT o r Dynam ic Mana gem ent session will be canceled , and any cha nges , unsaved or saved, will be lost.
With two exceptions, it is possible to completely configure your system using CFGEDIT. The exceptions are:
1. TFTP configuration
2. file attributes configuration
These two elements can only be configured using Manage Mode.
SFVRA CONFIGURATION MAN AGER
The SFVRA Configuration Manager allows a network to be configured and managed centrally. It is made up of two com p onents: the SFVRA-CF G database ( u sing either MS SQL Server, or MS Access) and the SFV RA- CF G cli ent ap plica tio n, wh ich is the in terfac e to the data ba se.
The network administrator can generate each sys te m’s configuration files separately, with the system’s view of the netwo rk, then transfer the confi guration file s e lectronically to the syste m. SFVRA-CFG provides a mechanism to define a system at a site, based on administrator-defined templates and standard configu rations. It also al lows the definit ion of major protoco l networks and their ISD N lines, mapping t hem to specific sites and then to systems at that site. The configuration files gene rated by SFVRA-CFG for a specifi c sy stem can be transferred to that sy stem using a proprietary, secur e p rotocol. For more inform ation on SFVRA-CF G, including installation and configuration instructio ns, refer to S FVRA Configuration Manager User’s Guide.
STARTING THE SFVRA-CFG APPLICATION
To start the SFVRA - CFG:
1. Open the SFVRA-CFG applicat i on .
3. From the menu bar, clic k on File then click on Connect, or click on the toolbar .
4. A dialog box similar to the following will be displayed:
Note that the first time you use th e SFVRA- CFG appli cati on, the lo gin ID is set to SFVRAC FG. If desired, you may edit this field t o change the logi n ID.
5. If required, enter your password.
6. Click OK.

ONFIGURATION OVERVIEW
CFGEDIT
CFGEDIT
CFGEDIT is a menu-driven utility. It consists of multiple, detailed submenus which allow you to set up or cha n ge co n f ig uration p a ra meters. T o be tter und erstand the st ru cture of CF G ED I T , re f e r to the CFGEDIT Map in the Appendix of the User ’s Gui de for the Ce nt ra l Si te Cyb erSWITCH .
CFGEDIT allows you to configure your system while the system software is still executing. These configuration changes are saved in a temporary copy of configuration data. At a convenient time, you may then reboot the system to make these changes permanent.
Configuration changes made using CFGEDIT are not recognized by SFVRA-CFG. Therefore, once you use CFGEDIT, you must always use CFGEDIT. This documentation is written under the assumption that you will use SFVRA-CFG . Howev er, if you plan on using CFGEDIT, refer to the Central Site documentati on, which is included on the CD-ROM for just such a purpose. In particular, note that the System Verification and Problem Diagnosis chapters of th e Central Site CyberSWITCH documentation are written using CFGEDIT techniques. Also, there are three sections of configuration chapters (Basic, Security, and Advanced Configuration sections) included in the CyberSWITCH Central Site documentation that are written for the CFGEDIT configuration utility.
EXECUTING CFGEDIT
After the system software has been loaded, you can start CFGEDIT by entering the following command at the system prompt as shown below:
[product name]>
cfgedit
As long as there is no other “change” session active (CFGEDIT or Manage Mode), access is granted, and the following menu is displayed:
From this screen you will begin the configuration process. Refer to Basic Configurat ion and succeeding chapters of the User’s Guide for the Central Site CyberSWITCH for details on using this
utility to perform specific configuration tasks.
Remember, changes to CFGEDI T are NOT dynamic. Change s are saved in a temporary copy of configuration data, and will not affec t the curren t operation of the sy stem in any way.
SAVING CFGEDIT CHANGES
To terminate the session, return to the main CF GED IT menu. If you have made cha nge s, select option 4 (Save Changes) before exiting. If you attempt to exit without saving, you will be prompted to do one of the f ollowing:
Main Menu:
1) Physical Resources
2) Options
3) Security
4) Save Changes
Select function from above or <RET> to exit:
Page 38

• save changes (Y) and exit
• do not save changes (N) and exit
• do not save ch anges as yet, but return to the Main Menu for further con figuration <RET>
To save change s a t th is point, an s wer Y for yes:
The save p rocess also includes a ll unsaved Manage Mode change s which were made prior to the CFGEDIT session, if any.
At your earliest possible convenie nce , restart the Smar tSw itch Remo te Ac cess Module. This will then activate the new configuration data.
DYNAMIC MANAGE MENT
EXECUTING DYNAMIC MANAGEMENT
The Dynami c Manag emen t fea tur e prov i des a real -t i me man age ment me chan ism; al lo win g yo u to change th e system’s configuration wi thout interrupti ng the execution of the system software. This feature c onsi sts of con sole co mman ds that en abl e you to d isp lay cu rren t s ystem par amet e r, ch ange many para me ters dynam ically, and write changes to disk fil e s so that th e y remain permanent. However, Manage Mode does have its limitations. Therefore, you will generally need to use both CFGEDIT and Manage Mode in order to make all appropriate configuration changes.
Configuration changes made using Manage Mode are not recognized by SFVRA-CFG. Therefore, once you use Manage Mode, you cannot use SFVRA-CFG. This documentation is written under the assumption that you will use SFVRA-CFG. However, if you plan on using Manage Mode, refer to the Central Site docum en tatio n, wh ich is includ ed on the CD -RO M for jus t such a pur pose.
Before using Dynamic Management commands, you must first enter the special Manage Mode by typing the following command at the system prompt:
>manage
Once Manage Mode is entered, the pr ompt changes from [system name]> to [system name]: MANAGE>. Whil e opera ting i n Manag e Mode, only Dy namic Manageme nt co mmand s are ava ila ble.
All other system commands are ignored until you exit Manage Mode.
The <CTRL><C> key sequence will terminate the current command and return you to the MANAGE> prompt. This is useful if you are in the process of responding to a series of prompts and you wish to abort the command without responding to the remaini ng p rompts.
Note: To use a command, you may enter the full command name as it appears in the HELP list,
or you may shorten the command to the point that it can still be distinguished from all other Dynamic Management commands.
UTILITY DYNAMIC MANAGEMENT COMMANDS
There a re several Manage Mode commands that are used for f unctions other than to configure the system. They are as follows:
Save changes and exit (Y or N)? or press <RET> for previous menu:

SAVING DYNAMIC MANAGEMENT CHANGES
The Dynamic Management commands allow s ystem data to be changed in real-time. These changes take effect immediately upon the execution of the command and remain in effect until the system is restarted. Once a software restart occurs, the changes are lost because the software reads its initial system data values from a series of configuration files.
To prevent desired data chan ges from bei ng overwritten by the restart process, the
commit
command should be executed. This command writes the current system data to the appropriate disk files, thus making all changes pe rmanent, even if the system software is restarted.
The
commit status
command displays the number of dynamic changes that have been made
using ea ch Dynamic Manageme nt command since the last
commit
was performed.
To return to the normal oper ating mode after you have commi tted your changes, issue th e following command:

PRI ISDN S
ERVICE
(US O
NLY
)
ISDN Primary Rate is a communication s se rvice that allows the system to make up to 23 connections over a sin gle line. It uses a 4-wir e T1 line that carries 24 chann els, each providing 64000 bps bandwidth. The service uses channels 1 to 23 as bearer (B) chan nels to carry connections between two systems. The 24th channel is used for signaling information (the data link).
You should request the following options for a primary rate line that is connected directly to a SmartSwitch Remote Access Module:
• B8ZS encoding
• ESF framing
• all channels should be Circuit Switched Data
• Hunt Group (if desired)
• call bandwidth supported (56Kbps, 64Kbps, and/or 384Kbps)
• CLID (calling line Id); usually there is no charge for this
In order to connect to the primary rate line, the customer needs a Channel Service Unit (CSU), which is integrated in to the SmartSwi tch Remote Acce ss Module . If the line is provided by a LEC or IXC, the CSU is required by the phone company to protect the phone network from any problems with customer premise equipment. At the time that the line is ordered, the customer may be asked for t he F CC reg is tr ation numb er fo r t he Sma rt Switc h Remo te Acc ess Modul e that i s bei ng used.
The cabling between the wall jack and the SmartSwitch Remote Access Module is very important, and is also where most problems occur. The system's PRI RJ-45 ad apter uses the international standard of pins 3, 4, 5, and 6 for transmit and recei ve. Most T1 lines in the United States and Europe use the tradition al 1, 2, 4, and 5 pins. We provide an RJ-45 to RJ-45 Mod-Tap adapter that will convert between the two wiring systems.

For non-U. S. and European installation s, a standard 4 or 8 wir e cab le with RJ-45 jac k s is sufficien t.
When the line is installed, you must ask the phone company the following questions:
1. What are the phone numbers for the line? (There may be more than one.)
2. Do I need to use any prefix when I dial? (For example, “9” for a Centrex line.)
3. What type of switch is the line connected to?
4. For #4ESS, what relea se of so f t wa re is runnin g on the sw i t ch ?
When the phone company installs the line, they assign it certain characteristics (sometimes called translations). These are different depending on the type of ISDN switch to which the line is attached. The customer must know what type of switch is being used.

Connecting the Module’s Cabling
to complete, though, is the Etherne t and PRI cabling. In addition, U.S. and Euro pean installations need a Mod-Tap adapter for each PRI port. Instructions for each are included below.
MODULE TO SMARTSWITCH 9000 ETHERNET CABLING
We supply two Ethernet cables with the module. Yo u will use thes e cables to connect the module’s Ethernet inter f a c e (s) to the Sma rtSwitch 9000’s Ethernet conne ction, pr ov i ding the module with LAN connectivity. To complete the Ethernet cabling:
1. Refer to the illustration of the 9W0006-400 for the Ethernet ports’ locations.
2. Insert the RJ-45 adapter at one end of the provided Ethernet cable into the module’s Ethernet port 1.
3. Insert the RJ -45 adapter at the other end of the Ethernet cable int o one of the SmartSwitch 9000’s Ethernet ports.
4. Repeat steps 2 and 3 for Ethernet port 2 if you will be using a second Ethernet connection.
MOD-TAP ADAPTER
The cabling between the wall jack and the module is very important, and is also where most problems occur. The system's PRI RJ-45 adapter uses the international standard of pins 3, 4, 5, and 6 for transmit and receive. Most T1 lin es in the Un i ted States and E urope use the traditional 1, 2, 4, and 5 pins. We provide an RJ-45 to RJ-45 Mod-Tap adapter that will convert between the two wiring systems.
For non-U.S. and Europea n installa tions, stand ar d cablin g is sufficien t (refer to follow ing section).
MODULE TO PRI SERVICE CABLING
The PRI cabling is not included with your module. You will need to determine the length of cable you need for your connection. The PRI cabling is the same type as the Ethernet cabling: straight­through twisted-pair cable with RJ-45 adapters at each end. To complete the PRI cabling:

OVERVIEW
This chapter provides instructions for:
• accessing a SmartSwitch Remote Access Module f or the first time
• remote ly accessin g the SmartSwitch Remote Acce ss Module after the first time
Refer to the modul e illustration in Hardware Overview to help you locate the ports described in the following sections.
ACCESSING A NEW MODULE
The two methods of accessing a new module are:
• access through a PC using a terminal application
• access by Telneting to the module usin g the initial default IP addres s
Once you have u se d one of the tw o me thods to acces s to the module, you should:
• establish an administration sessi on with the module
• assign the module’ s new IP addr ess
• access the module’s re lease note s
For more detailed instructions, refer to the sections below.
INITIAL ASSESS USING A PC AND A TERMINAL APPLICATION
Connect one end of the supplied null mode m cable to th e RS232 console port on the module, and the other end of the cable to the communication port on the PC. On the PC you must then execute a communication package to emulate a terminal (VT100).
Use the following default values for your communication package:
Baud rate 9600 Parity None Data b its 8 Stop bits 1 Duplex Full
After you have connection to the module, you will be ready to establish an ad minis tr ation ses sion.
INITIAL ACCESS USING TELNET
You can use a remote device to the Telnet into modul e using the module’s ini tial d efault I P address (192.186.254.254). The remote device can be a device with Telnet client software, such as a PC or a UNIX workstation, or it can be a second module or a Cabletron CyberSWITCH. Note that the modules and CyberSWITCH systems have built-in Telnet client software.
Page 48
48 SmartSwitch Remote Access Module
If a SmartSwitch Remote Access Module or second module is acting as the Telnet client, simply enter the following console command to Telnet into the module:
telnet <
192.186.254.254>
Refer to the System Commands chapter for a complete listing of available Telnet comma nds.
If a remote device other than a Cab letron product is acting as the Tel net client , u se the device’s Telnet applicat ion to connec t to the initial de fau lt IP address (192.1 86. 254. 254).
After you make a Telnet connection, you will be ready to establish an administration session (refer to the following section for instructions).
For more information on Telnet, refer to the Remote Management chapter.
ESTABLISHING AN ADMINISTRATION SESSION
Once you have connected to the module using either a terminal application or Telnet, you will be prompted for a login id. Enter:
admi n
You will then be prompted to enter a password. All preinstalled systems are preconfigured with the same password. This is the password that is used the first time a login occurs. Being sure to enter all lowercase letter s as shown b elo w:
admin
You will now see the system prompt. We recommend that you select a new password. To do this, enter th e following command at the sy stem prompt:
pswd
Follow th e onsc re en inst ruc tion s to ch ange the pa sswor d. N ote t hat t he passw ord mus t be a 3 to 16 nonblank character string, and that it is uppercase and lowerca se sensiti ve.
Next, fol low the instr uctions below to assign the module’s n e w IP address.
ASSIGNING THE MODULE’S IP ADDRESS
To assign the module’s new IP address enter the following command at the system prompt:
ipconfig
As prompted, enter:
• the syste m’s IP address
• the required subnet mask
• for the sy stem’s default route, enter the IP address of the syste m’s defaul t gateway ( e nter 0 if there is no default route)
Follow the instructions to restart the module so that the configuration changes will take effect.
Once you have assigned the module’s IP address, you will Telnet into the module when you need access for functions su ch as system mainte nance, diagn osis and veri ficatio n procedures , or entering console commands.

YSTEM VERIFICATION
OVERVIEW
After you r SmartSwitch Remote Access Module has been con f igured, and before proceeding with normal system operation, i t is necessar y to verify that the system is functional. This chap te r provides instructions for verifying the system hardware and system configurati on.
You only need to perform the verification procedures for the opt ions that apply to your configuration. For example, if your configuration does not use SNMP, skip the SNMP verification section.
To perform the verification procedures, WAN lines must be available and ready to use. LAN attachment componen ts must also be avai lable and ready to use.
During som e of th e pro ced ures , we a sk yo u to en ter an admin ist ra ti on cons ol e com mand. To ent er these command s, you must ha v e an a ctive adm i ni s tr a ti o n se s s i on . I f yo u nee d instruc tions for startin g an administration session, refer to Accessing the SmartSwitch Remote Access Module.
Note: At least one remo te devi ce is requir ed to procee d with many of th e verific atio n procedure s.
VERIFYING HARDWARE RESO URC ES AR E OPERATIONAL
To verif y the op e ration of the WAN and LAN hardware resources:
1. At the system prompt, enter the
dr
command to display current system messages. Determine if the WAN adapter resource is operational by v iewing the syst e m messages. At th e administration console type:
dr
<return>
