Unique System Features

UNIQUE SYSTEM FEATURES

The CyberSWITCH combines unique features that improve cost-effectiveness, reliability, and
performance for wide area network connections to remote devices. These features include:

• Bandwidth Agility

The CyberSWITCH dynamically controls the bandwidth in use between itself and other PPP

devices. This is accomplis hed by establishing and disconnecting calls. The numb er 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

through put p ar amet er s. As n etw ork band wid th r eq uir emen ts i ncr ea se or decre ase , the syst e m

will automatically adjust the number of networ k connectio ns. Thus, your netwo rk costs will

reflect the actual bandwidth being used.

• Filtering

The CyberSW ITC H’ s filte ring fea ture allow s you to contro l the flow of fram es thro ugh the

network. Filtering becomes necessary if you need to restrict remote access or control

widespread transmission of sporadic messages. Customer-defined filters ca n forward

messages based on addresses, protocol, or packet d ata.

• Combining Leased Line and Switched Connections

Use the Switched Connections feature to automatically backup failed or overloaded leased

lines (for example, in peak hour overflow situations). The capability of combining switched

connections with leased line capacity allows you to reduce costs and greatly improve the

reliability and perfo rma nce of leased line netw orks .

The following graph illustrates the relationship between cost and hours of usage when

comparing a switched connection to a dedi cated connection:

• Data Compressi on

The Cyber SWITCH can negot iate com press ion alg orithms with an other device on the network .

After successfully negotiating compre ssion, data is compressed by the remote device and

transmitte d to the CyberSWITCH system. The sys te m decompresse s 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.

• Data Encryption

The CyberSWITCH encry p tion option provides da ta e ncryption through th e Data Encryption

Standard (DES) algorithm. DES provides data security for transmissions over the WAN

between e ncryption devices. Options are available for encrypting communications over point-

to-point, frame relay, or Internet-based WANs. For more information, refer to the Encryption

Overview and IP Security discussions.

To activate the data encryption option on the CyberSWITCH, you will need to properly install

and configure the encryption adapter on the system.

• Dial Out Capability

The CyberSWITCH syste m w ill dia l out to rem ote de v ices . Thi s feat ure a llo ws the sys t em to

accept u ser data rec ei ved on t he Et he rnet LAN o r IS DN n etwo rk a nd i niti ate a d ata co nnec tion

to the remote device specified in the user data. This allows devices on the local LAN to initiate

connection s to netw o rk s co n n e ct e d to th e system over th e sw i tc h e d d ig ital ne tw ork. Th e

system monitors the connection for utilization and will remove the connection when it becomes

idle.

• Digital Modem

The CyberSWITCH’s dig ital mo d e m capa bilit y all ow s ana lo g mode m s to be inter mix ed with

ISDN, as required, to best fi t specific networking needs. The d i gital mo dem adapter combines

both hardware and so ftware el ements to s upport a number of modems on a sin gle boa rd (from

eight V.34 modems to t hirty K56Flex modems, depending upon adapter model). The digital

modem feature conform s to the V.90 standa rd.

• Dynamic Management

Manage Mode provides a “real-time” managemen t mechanism that allows many sys tem

paramet e rs to be changed wi thout inter ru p ting the current execution state of th e system

software. This featur e consists of a ser ies of console commands that enable a user to display

current system par a m et e rs , ch an g e ma n y p ar a m et e rs dyn a m ically, an d write changes to di s k

files so that they remain perm ane nt.

• High Speed Digital Connections

The CyberSWITCH system supports 56Kbps and 64Kbps connections to remote locations.

These dial-up digital connections provide reliable high throughput connections for efficient

data transfer for the same cost as analog connection s . 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.

• IP Filters

IP filters allow you to control the transmission of individual IP packets based on the packet

type. You can specify packet type by IP address (source or destination) or by IP protocol (TCP,

UDP, ICMP).

Once you specify a packet type, two forms of IP filtering are available:

• Forwarding Filters, applied at discrete points of the IP processing path to determine if a
packet continues its normal processing, and a

• Connection Filter, which determines if an IP packet requiring a WAN connection may con­tinue.

Unique System Features

•IP Security
The Cy b erS WITC H e ncrypti on option implem e n ts En c apsulating Se cu r i ty P a y load (ES P )
protocol. ESP allows you to use Cy b e rSWITCH nodes to implement a Secure Wide Area
Network usi ng the Intern e t as a b ackbone. ESP provides confidentiality of data transmissions
using encryption to assure that pack ets intercepted during transit through the in ter n et c an not
be interpreted.

The CyberSWITCH encryption option supports ESP Tunnel mode, in which an entire IP
datagram (includ ing its header) is encrypted and place d in a new IP datagram. This option
provides the flexibility to choose which IP addresses must be sent encrypted data, and which
may receive plain (unencrypted) data. The CyberSWITCH encryption option provides WAN
connectivity for up to 92 B channels (with PRI and/or BRI connections).

• Link Layer Encryption
The CyberSWITCH also provides the ability to do encryption at the PPP layer usin g Encryption
Contr ol Protocol with comp atible de vices.

• Multiple MAC/IP Addresses
This featu re allow s two or more nod es to back up each other th rough th e use of the Connecti on
Services Manager (CSM).

With this feature, two or more identically configured CyberSWITCH nodes on the same LAN
can be monitored by CSM. Should CSM notice some con di tion which precludes one of the
CyberSWITCH no des from proper ly p erfo rming its fun ctio n, it will orde r the other
CyberSWITCH node to take over the other’s duties by taking on its iden tity (i.e., its MAC an d
IP addresses).

•Packet Capture
In order to monitor incoming LAN data, the CyberSWITCH 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.

• RS232 Port: Dual Usage
If your installation requires you to process PPP-Async data, this feature allows you to use the
RS232 port for either console acc ess or a serial data connection. This dual usage is possible
through th e CyberSWITCH’s support of Autosense mode (th e system default) and Terminal
mode:

• Autosense mode determines whether you are trying to connect using a VT emulation or PPP-

Async, and connects you appropriately. (VT emulation requires you to perform four car­riage returns to receive a login prompt.)

• Terminal mode assumes that you o nly wa nt to conne ct u sing VT e mulati on. A log in promp t

is displayed as soon as the connec tion is made.

•Security
Security is a key issue for all central site network mana gers and is a priority with the
CyberSWITCHs. The products provide high level features that help prevent unauthorized or
inadvertent access to critica l data and resources . They support extensive security levels
including:

• PPP PAP and CHAP

Internet Service Providers.

• Simultaneous Connections
The CyberSW ITCH system supp orts simult a neo us connec t ion s to mult iple loc a tions . 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.

INTEROPERABILITY OVERVIEW

“Interoperability” is the ability to operate and exchange information in a heterogeneous network.
The CyberSWITCH supports interoperability with many different remote devices over ISDN.

INTEROPERABILITY PROTOCOLS

In order to commun icate wi th vari ous remot e devic es over I SDN, the CyberSWI TCH must i dentif y
the device type and the protocol it is using.

The CyberSWITCH supports the following line protocols:

• HDLC Ethernet Frames

• Ordered Protocol for Ethernet Frames

• RFC1294 Based Encapsulation for IP Datagrams

• Point-to-Point Protocol (PPP) Encapsulation for IP Datagrams

The CyberSWITCH supports the following encr yption protocols:

• Encapsulating Security Payload Proto col (ESP)

• Encryption Co ntro l Protoc ol (EC P)

The CyberSWITCH supports the following PPP protocols:

• Link Control Protocol ( LCP)

• Multilink Protocol (MLP)

INTEROPERABILITY DEVICES

Remote devi ces that may connect to the Cybe rSWITCH include the following:

• MAC Lay er Bridges

•IP Host Devices

• IP Router Dev ices

• IPX Route rs

• 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 another. IPX routers 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.

ENCRYPTION OVERVIEW

Cabletron’s encryption options provide two popular approaches for encrypting WAN
communica tions, each with di stinct advantag es i n certai n appli cations . The se opti ons are: Netwo rk
Layer Encryption and Link Layer Encryption.

NETWORK LAYER

Cabletron’s Network Layer Encryption is an IP Security-based form of encryption. IP Security
(IPSec) can potentially reside in many devices within the network. Since IPSec is specific to IP, data
must be cont ained in an IP d ata gram in o rder for en crypt ion to take pla ce. Th is also imp lies that an
IPSec-compliant switch or router must perform network-layer routing. A device which does not
perform network-layer proce ssing (such as a pure bridge) will not be capable of IPSec-ba s ed
encryption. Non-IP protocols su ch as IPX and AppleTalk mu st be encapsulated within IP in order
to take advantage of IPSec.

IPSec is primarily aimed at providing secure communications across IP networks such as the
Interne t . Data can trave rse multiple intermediate (untrusted) nodes (such as Internet backbone
routers) while still ensuring strong data security. But it can also be applied in point-to-point
networks where the layer-3 protocol is IP (for example, IP transported across the WAN using PPP).

Network-layer encryption works as follows:
IP datagrams transmitte d from one LAN to another LAN funnel through a CyberSWITCH node
where they are encrypted and encapsulated. The destination address on the encapsulated
datagram is that of the C yberSWITCH node servicing the other trusted subnet.

When the IP datagram reache s the destination CyberSWITCH node, the Encapsulating Security
Payload (ESP) header is remo ve d, the ESP payload is decrypted , an d th e original IP datagram is
forwarded to its original des tin atio n.

CyberSWI TCH encry ption requir es a dditional Security Associati on information that can be supplied
through CFGEDIT. Each security association identifies a range of IP addresses, encryption
parameters to be used to encrypt communications to those IP addresses, and the IP address of the
peer CyberSWITCH (or other ESP node) responsible for decrypting the communications. The peer
will have knowledge of the same security association.

Security associations between peer CyberSWITCH nodes are identified by a Sec urity Parameter
Index (SPI), which is a 32-bit number. The SPI is transmitted in the ESP header and is used by the
peer CyberSWITCH node to identify the necessary information to decrypt the E SP payload.

IP datagrams to these IP destination addresses are encrypted and encapsulated with an ESP header.
The ESP header indicates a destination address of an intermediate CyberSWITCH node which will
be responsible for decrypting and decapsulating these packets before sending them on to their
intended destination.

LINK LAYER

Link layer encryption occurs at layer 2 of the ISO networking model. In the case of a WAN, PPP
acts as a lay e r 2 p rotocol. Encryption C ontrol Protocol (ECP) serves to handle encryption of a PPP
datagram.

Central Site Remote Access Switch 37

YBER

SWITCH

Security Overview

Link layer encryption is in dependent of any network layer protocols . Sin ce PPP provides t ransport
of IP, IPX, AppleTalk, and other protocols, link layer encryption based on ECP provides multi­protocol e ncrypti on by def ault. Dev ices im plementin g it can act as router s or brid ges, as l ong as the
underlying WAN protocol is PPP.

To use link layer encryption, the co nnection between encrypting and decrypting devices must truly
be point-to-point. This includes ISD N dial-up connec tions, or point-to-point dedicated lin e s.

SECURITY OVERVIEW

The system provides several options for validating 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.

Levels of security include no security, device level security, user level security, and multi-level
security. Device level security is an authentication process between devices, based on protocol and
preconfigured information. Sec urity information is configured either in the system’s On-node
Device Dat abase, or in a ce ntral database such CSM. Here the network administrato r sp e cifies all
of the security information for each individual user. A portion of this information is used to identify
the remote device. The remain ing data is used to perfor m user valida tio n after user iden tifica tion
has been completed.

User level security is an interactive process. It is currently supported on the system through the
TACACS or ACE server programmed for use with security to ken cards. With user leve l security,

the potential network user explicitly connects to the server and must properly “converse” with it
in orde r to co n ne c t with othe r devic e s b ey o n d the serv er .

Import ant to user level authentication is th e se curity token card. Th is card, programmed in
conjun ction with the authentication server, gene rates random passwords. These passwords must
be supplied correctly at syst em login tim e, or acces s to the networ k will be den ied. The secur ity
token cards should be issu e d to each user on the network to properly maintain system inte grity.

Multi-level security provides device level security for all remote devices. Individual devices may
be configu red for user level authentication as well. In this case , device l e ve l authentication takes
place between the system and the remote device. Then a specific user must initiate user level
authentication by sta rting a Telnet session. Both levels of authentication must b e satisfied before
traff ic can pass.

NETWORK INTERFACE OVERVIEW

The network interface is the physical connection of the CyberSWITCH to a data network. For
example, the Ethernet resource in the system provides a net work interface to an Ethernet LAN. The
ISDN lines in th e s yste m prov i de netw ork i nter fac es t o mu ltip le r emote net wor ks. Beca use of th eir
switched nature, the ISDN lines provide virtual network interfaces. That is, the same physical ISDN
line can actually c onnect to different remote networks by d ialing a different phone number.

The CyberSWITCH 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

USER’S GUIDE

38 CyberSWITCH

• WAN IP Network Inte rface

• WAN (Direct Host) IP Network Interface

• WAN RLAN IP N etwork Interface

• WAN RLAN IPX Network Interface

• WAN (UnNumbered) Network Interface

The variety of ne twork interfaces allows the install a tion of a wide ra nge of devices at re mote sites.
As illustrated below, you can simultaneously choose bridges, routers, or host devices based on the
speci f ic re mote site requ i r e ments.

In the diagram above, t he LAN Interface 128.1. 1.1 is attach ed to the IP network 128. 1.0.0. The WAN

REMOTE ISDN DEVICES

The CyberSWITCH provides a centralized concentrator function for remote ISDN devices. The
devices can be separated into the following categories:

• remote ISDN bridge devices

• PC based terminal adapters

• ISDN enabled workstations

• other ISDN routers

Typical remote ISDN bridges provide one Ethernet port and one basic rate ISDN port. The basic
rate port is connected to the switched digital network and is used to make connections to the
CyberSWITCH. The Ethernet port is used to connect to a remote LAN. The remote bridge device
sends Ethernet frame s from device s on the remote LA N over the switched network .

PC-based terminal adapte rs connect to a remote personal compute r an d us e the switche d d igital

DIGITAL MODEMS

The CyberSWITCH supports the DM-8, DM-24, DM-24+ and DM-30+ Digital Modem adapters.
These adapters allow the CyberSWITCH to receive calls from asynchronous PPP remote devices
connected by modem. They also provide a vehicle for remote analog console access.

Available Digital Modem adapters include the following type and quantity of modems on a single
adapter card:

The Digital Modems support the following remote modem options:

All modem adapters:

• V.34+ (33.6 Kbps)

• V.34 (28.8 Kbps)

• V.32 bis (from 300 bps to 14.4 kbps)

• MN4 (with error control)

• MN5 (with data compression)

• V.42 (with error control and data compression )

DM-24+ and DM-30 + modem adap ters only :

• K56Flex (56 Kbps) (firmware may be upgraded to the ITU V .90 standard)

The number of adapters in a system is limited by the number of ISDN channels and adapter slots
available. A maximum of four DM-8s or three DM-24s, DM-24+s, or DM-30+s can be inst all ed and
configured at one time. You may combine DM-8s and DM-24s in the same system as long as you
do not exceed a maximum of three cards.

Note: Digi tal Modem adapter s are al so k nown as DIG-8 ( DM-8), DI G-24 (DM-24 ), DIG-2 4+ (DM-

24+), and DIG-30+ (DM-30+).

For the DM-24+ and DM-30+, no “+” follows the Digi tal Modem adapter designation in
CFGEDIT. Do not be alarmed; in the case of th e DM-24 and DM-24+, th e sy stem
automatically distinguishes between the two different types of modems.

DM-8 eight V-34+ (33.6 Kbps) modems

DM-24 twenty-four V-34+ (33.6 Kbps) modems
DM-24+ twenty-four K56Flex (56 Kbps) modems

OFTWARE OVERVIEW

OVERVIEW

The system software fits into one of th re e categories:

• system so f tware for the System, adapt er modules and ad ministrati on functio ns

• administration software that provides configuration, diagnostics and mai ntenance on the
CyberSWITCH

• system files containing configuration and operational information

This chapter provides an overview for each of the above software categories.

SYSTEM SOFTWARE

Include d wi th each CyberS WI TCH is a set of 3.5" high-density diskette s which conta in system
software, administration software and all required system files. The system software is a set of
executable programs that collectively implement the system functions. These programs provide the
core interoperability hub feat ures, such as centralized management and high speed digital
connections. Depending on t he software version purchased, it supports up to eight, sixteen, thirty­two, or forty-eight connections.

Instructions for installing new system software and for upgrading existing system software can be
found in the Upgrading System Software chapter.

ADMINISTRATION SOFTWARE

A CyberSWITCH may be configured as an SNMP Agent. An SNMP Manager, such as Cabletron’s
Spectrum product, may u s e these SNMP Age nts to monitor individual network devices' op e rating
statistics and configuration elements. The software for this feature is included with the system
software.

Carbon Cop y, a communication s package from M icrocom Cor poration, is included with the system
software. Carbon Copy allows access to all administration functions through the remote
administration port on the CyberSWITCH. The CyberSWITCH is configured for 9600 bps d irect
connect for Carb on Copy remote a ccess. This modem configuration setting may be changed if
necessary. Refer to the Car bon Copy section in the Re mote Managem ent chapter for instructions on
chang in g mo dem conf ig u r a tio n se t t in gs .

The Manager (Administration Services), is a separate diskette available as an option when you
order your system. T his diskett e contains th e Carbon Copy “Guest” soft ware to access the remote
administration console option.

System Files

SYSTEM FILES

The system files consist of the required configuration files, as well as the operational files that the
CyberSWITCH mainta ins . All of these files may be acces sed by using ava ilab le admin istrat ive
commands. (Refer to the System Commands chapter for details.)

Below is a brief description of the configuration and operati onal file s.

CONFIGURATION FILES

The configuration files store the configuratio n da ta. These file s are located in the sy ste m’s
\config directory. You can maintain these files by using the CFGEDIT configuration utility,

which is delivered with the system. You can also make changes to these fil e s through Mana ge
Mode.

The configuration files associated with the system are:

network.nei

This configuration file contains info rma tion about the switched netw ork.

devdb.nei

This file contains the On-node Device Database configuration information about each remote
device.

node.nei

This configuration file contains node -spec if ic informat ion like resou rce s, lines, Cybe rSW ITC H
operating mode and secur ity options, along with the Throughput Monitor Configu ration
information. If enabled, SNMP configuration information is also in this file.

lan.nei

This file contains configuration information used when the bridge is enabled. This file also contains
information for the Spann ing Tr e e protoco l used for the bridge. Information from thi s file is
configured and used only when the bridge is enabled.

ip.nei

This file contains configuratio n info rma tion used when th e IP routing is enable d. This file also
contains information regarding network interfaces, RIP, and static routes. Information from this file
is configured and used only when the IP routing is enabled.

ipx.nei

This file contains configuration information used when the IPX routing is enabled. This file also
contains information regarding network interfaces, RIP, and static routes. Information from this file
is configured and used only when the IPX routing is enabled.

filter.nei

This file contains all filter configuration information (bridge, hardware, and IP). This file is new to
Release 7.2 software, but is compatible with previous software versions, which contained filter
information in the lan.nei and/or ip.nei files. With Release 7.2 configuration changes and
configuration file updates, this filter information will be moved to filter.nei.

USER’S GUIDE

72 CyberSWITCH

atalk.nei

This file contains configuration information used when AppleTalk Routing is enabled. This file also
contains information regarding ports and static routes. Information from this file is configured and
used only when the AppleTalk routing is enabled.

platform.nei

This is a text file that contains a list of platform names and the currently selected platform. Each line
in the file contains an ASCII string repres en ting a platform name and a corresponding integer
value. The integer value is the crucial item, since this is what the system software uses to determine
whether any special action is necessary. The string is displayed when the

ver

command is issued.

sdconf.rec

This is not a system file; it is a configuration file delivered on the ACE Server. However, you may

TFTP th i s file to th e sy st e m’s \config directory as an alternate method of providing the system
with ACE Server configurat ion inf ormat ion.

OPERATIONAL FILES

While the Cyb e rSWITCH is running, it col lects syst em statistic s and logs system me ssages. The
system maintains these statistics and messages in separate memory-resident tables. The ten most
recent versions of each table are available on the system disk.

You can re t ri eve and vi e w the current memo ry- reside n t ta bl e s at any time by u sing the foll o w i ng
console commands:

dr

This command will display system messages.

da

This co m m and will dis p la y a u the ntica ti o n me ssage s.

ds

This comma nd will display system stat istics.

You can write the tables to disk by using the following commands:

wr

This command will wri te the curren t system mess ages to disk.

wa

This command will wri te the curren t system mess ages to disk.

ws

This command will wri te the curren t system statistics to disk.

Note: When the system is shut down, the tables are automatically written to disk.

The system stores the tables in ASCII format files on the System disk. When the system writes
system messages to disk, it stores th e m in the following location:

Directory: \log
File Name: rprt_log.nn
Where “nn” is an integer that is incr ement ed e ach time a new file is written.

When the system writes system statistics to disk, it stores them in the follo wi ng locations:

OVERVIEW

This chapter was designed to be a guideline f or orderin g ISDN serv ice in the United Stat es.

For BRI ISDN Service:
If you are using NI-1 lines, try using EZ-ISDN Code s to order BRI service. If your service provider
does not support EZ-ISDN Codes, try using the NI-1 ISDN Order ing Co de s .

If your ser vice prov iders do es not su pport ei ther type s of codes , or, if you are usin g a non-NI-1 l ine,
refer to Ordering BRI ISDN Lines using Provisioning Information.

For PRI ISDN Service:
If you are using PRI lines, refer to Ordering PRI ISDN Lines.

ORDERING NI-1 LINES USING EZ-ISDN CODES

If you are using a NI-1 switch type and your service provider supports EZ-ISDN codes, we
recommend using the EZ-ISDN 1 code. EZ-ISDN 1 provid es alternate circuit-switched voic e/data
on both B-Channels. There is a CSV/D terminal associated with each of the B-channels.

The B-channels will be given a unique primary directory number capable of making/receiving one
circuit-switched voice or circuit-switched data call. Additionally, calling line Id is also supported.

ORDERING NI-1 LINES USING NI-1 ISDN ORDERING CODES

If you are using a NI-1 switch type and your service provider supports ordering codes, we
recommend NI-1 ISDN Capability Package I. This package includes circuit-switched data on two B
channels. Data capabilities include Calling Line Id. No voice capabilities are provided. The lack of
voice feature may save you money. However, package K or M will also work.

ORDERING BRI ISDN LINES USING PROVISIONING SETTINGS

If your service provider does not su p por t EZ- IS DN or ISDN Order ing Co de s, o r you a re u sin g a
non-NI-1 line, use this section when ordering your BRI ISDN line.

When the phone company installs the line, they assign it certai n characteristi cs. These are differ ent

depending on the type of ISDN switch to which the line is attached. AT&T’s 5ESS NI-1 and
Northern Telecom’s DMS100 NI-1 are among the most popular.

When ordering an ISDN line, there are general steps to follow that apply to all types, and there are
steps specific to your line type. The general steps to follow are:

1. Contact your service provider to determine the type of available switch.

2. Ask your service provider for the available types of ISDN services.

BASIC INFORMATION FOR ORDERING PRI ISDN LINES

ISDN Primary Rate is a communications service 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).

The customer should request the following options for a Primary Rate Line that is connected
directly to a CyberSWITCH:

• B8ZS encoding

• ESF framing

• all channels should be Circuit Switched Data

• Hunt Group (if desired)

• call bandwidth su pported (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 must provide a Channel Service Unit
(CSU). 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 t ime that the line

is ordered, the customer may be asked for the FCC registration number for the ty pe of CSU that is
being used. The CSU should support ESF framing and B8ZS line en coding.

The cabling between the CSU and the CyberSWITCH is very important, and is also where most
problems occur. The system’s PRI RJ-45 adapter uses the international standard of pi ns 3, 4, 5, and
6 for transmit and recei ve. Most T1 lines in the United States use the tra ditional 1, 2, 4, and 5 pins.
We provide an RJ-45 to RJ-45 Adapter that will convert between the two wiring systems. The
customer may still need a special cable to connect from a RJ-45 jack to a DB-15 connector, if that is
what the CSU provides.

Otherwise, a st andard 4 or 8 wire cabl e with RJ-45 jacks i s sufficient between the Adapter and the
CSU.

When the line is installed, the customer 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.)

This chapter provides a description of th e har dware install ation process. It includes:

• pre-installation requirements

• selecting slots for adapters

• setting switches

• inserting adapters into backplane

• connecting inter-board cables

Your distr ibut or may have al rea dy co mplete d th is ad apter instal lati o n. If no t, foll ow this c ha pter ’s
specific instructions .

PRE-INSTALLATION REQUIREMENTS

Before you begin the installation process, be sure to:

• Choose a suitable setup location

Make sure the location is dry, ventilated, dust free, static free, an d free from corrosive
chemicals

• Verify system power requirements

If applicable, make sure the line voltage select switch is set for the AC input power source
you are going to use. The appropriate standard power cord is supplied with the system.

CAUTION:
When changing the line voltage select switch, make sure the AC power cord is unplugged.

• Verify cabling requir ements

The cabling included with your shipment will depend on the country in which your system
will operate. If additional cabling is needed other than what was shipped, contact your
distributor.

Only qualified personnel should install adapters into the
CyberSWITCH.

!

CAUTION

Any time you remove the system module cover, unplug the power
cord. Failure to do so may result in personal injury or equipment
damage.

The CyberSWITCH is sensitive to static discharges. Use a
grounding strap a nd observe all stat ic precautions dur ing this
procedure. Failure to do so could result in damage to the
CyberSWITCH.

USER’S GUIDE

• Verify administration console requirements

You will need an administration console to install your system. (We do not provide this.)
The syst em su pport s t wo adm inis tr ation con sole opti o ns: a loc al ad min istr at ion co ns ole i n
which a keyboard and monitor are direc tly connect e d to th e system, or a remote
administration console in which an IBM Compatible PC is remotely connected to the
system. Refer to Accessing the CyberSWITCH for more details.

• Provide a diskette for configuration backup

If you choos e to b ack up your config uration to diskette (as oppose d to a Network

Management Station), you will need a 3 1/2” DOS formatted high-density diskette. Details
on performing a configuration backup are described in the Routine Maintenance chapter.

SELECTING SLOTS FOR THE ADAPT ERS

Most adapter settings are dependent upon the slot in which the adapter will be installed and/or
configured. So, to determine each adapter’s settings, you must first select the proper slot for each
adapte r. As you se l e c t the slot fo r e a ch a dapter , n o te the slot nu mb e r yo u p la n to ass ociate w it h
each adapter. You will need this information for the next step: Adapter Settings.

Throughou t this section, we refer to LAN, WAN, DM (Digital Modem), and Encryption adapters.
The following chart lists the adapters in each group.

A CyberSWITCH sup ports a maximum of one LAN, one Encrypti on, and up to six “othe r” adapters
(WAN+DM). Of this total of six, a maxi mum of 4 DM-8s or 3 DM-24s, DM-24+s or DM-30+s are
allowe d. Refe r to the Hardware Overview for any addit ional restriction s th at may be platform-
specific.

The following steps determine each adapter’s slot placement. Note that all WAN, DM, and
Encryption adapters fall between the CPU and the LAN in the backplane.

1. Select a WAN adapter for the first sl ot adjacent to the CPU. Then continue as foll ows:

a. If you are installing only WAN adapte rs:

Continue to select WAN adapters for the next available slots until you have selected a slot
for all WAN adapter s.

b. If you are installing WAN adapters and DM adapters:

Select a DM adapter for the next availabl e slot. Continue alternating WAN and DM
adapters until you run ou t of WAN or DM cards. At th is point, co ntinue with th e remainin g
WAN or DM adapters until you have selected a slot for all remaining WAN or DM
adapters.

ADAPTER INTERRUPT AND I/O ADDRESS SETTINGS

WAN ADAPTERS

The WAN adapters (except for the RS-232 and V.35) use jumpers to se t th e interrupt and switches

to set the I/O address. The following chart contains the WAN adapter’s interrupt jumper and I/O
addre s s switch se t t i ng s re qu i r e d fo r e a ch co nf i gu red sl ot nu mb e r .

Refer to the System Adapters Appendix for location and number ing conventi ons of the interrupt
block and I/O sw itch. Note the fol lowing:

• concerning the interrupt block : On som e boards, su ch as the PR I -8 , th e in t e rrupt block is num ­bered from le ft to right, beginni ng with positi on 3 on the left. On the PRI-23 an d PRI-23/30, th e
interrupt block is numb e red from right to left, wi th position 3 starting on the right.

• concerning the I/O Switch: If the adapt er’s I/O address switches are labeled with open as opposed
to either off or on, open corresponds to off. On the PRI-23/30, S8 on the I/O Switch is not used.
The board should function properly with th e switch in either the ON or OFF position.

DM-8 A

DAPTER I/O ADDRESS SETTINGS

The DM-8 is unique in that it has no interrupts, and uses jumpers instead of switches for its I/O
address settings. The DM-8 will take on the interrupt of the slot in which it is configured. You only
need to set its I/O address. When configuring DM-8 adapters, use 380 for the I/O address of the

DM-24+ AND THE DM-30+ ADAPTER ADDRESS SETTINGS

The DM-24+ and the DM-30+ adapters both use switches to set the interrupt, I/O address, and
MVIP clock termination . Switch blocks SW1 and SW3 determine I/O address, SW2 and SW4
determine interru pts, and SW5 determines MVIP clock termination.

Note: Refer to the System Adapter Appendix for sw itch location s. Con figure a DM-24+ or a D M-30+

only in slots 2, 4, and/or 6. Switch settings will differ depending upon the slot you wish to
configure. Refer to the following charts/descriptions:

To set the IRQ so that it is on, refer to switch bl ocks SW2 and SW4. Set the c orresponding IR swi tch
on these switch blocks to on, with all others off. For exampl e , for an IRQ s e tting of 11, IR11 (switc h

4) on switch block SW2 should be on; all other IR switches on SW2 and SW4 should be off.

To set the address, refer to switch blocks SW1 and SW3. SW1 is labeled 1 through 8 (A15 through
A8). Switches in this block should always remain on, on, on, on, on, on, off, off. SW3 varies based on
address. Use the following chart:

For example, for an address of 300, A9 (sw it ch 7) and A8 (switch 8) on SW1 should be off; all
remaining switches on SW1 and SW3 should be on.

Note: For all configurations, switch 4 on SW4 is a reserved switch and must always remain OFF.

MVIP SETTINGS

The following adapter s have MVIP connectors:

•PRI-23,

•PRI-23/30,

•DM-8,

• DM-24,

• DM-24+, and

• DM-30+

In order to establish an MVI P bus, follow this process:

1. First, selec t s lots for all MVIP adapter s. If y ou are usi ng both P RI and D M adapters , begin with
a PRI adapter, and then select slots alternating PRI and DM adapters as described in Selecting

Slots for Adapters.

2. Next, terminate the MVIP jumpers on both the first and last adapter in the MVIP adapter series.
(All other MVIP jumpers on the adapters between these two should be left unterminated).

• To terminate the MVIP bus fo r the PRI-23, place the jumpers vertically on JP9.

• To terminate the MVIP bus fo r the PRI-23/30, place the jumpers vertically on JP9.

• To terminate the MVIP bus fo r the DM-8, place jumpers horizontally on J5 and J6.

• To terminate the MVIP bus fo r the DM-24, turn switch blocks S1 and S4 “ON”.

Note: DM-24 adapters may have either toggle or slide switches. In either case, the

switch is “ON” if it is toggled or slid to the right. All four switches should
always be set in the same direction.

• To terminate the MVIP bus fo r the DM-24+ or the DM-30+, place the four switches in

switch block SW5 to the “ON” position.

3. Install MVIP adapters into pre-selected slots.

4. Install MVIP ribbon cable. Refer to Connecting Adapter Inter-board Cables.

5. Install TDM ribbon cable. Refer to Connecting Adapter Inter-board Cables

In order to improve si gnal quality (which in tu rn results in higher modem-connection rates), you
should terminate the MVIP bus at both ends as recommended in step (2). However, not all system
configurations support this. Note that PRI-8, PRI Expansion and BRI boards do not support MVIP
termination.

Note: MVIP termination at both ends (step 2) also applies to six PRI-23/30 configurations.

• E1/R2 signaling

Refer to the f ollowing chart for correct se ttings. Place the jumper on the p ins identifi e d to enable
the funct ion, unless sp e cified othe rwise.

Note: When setting jumpers, orient the adapter so that the bus connectors are at the to p of the

adapter, and all pin numbers are in an upright position.

Note that JP1 has an unusual pin-numbering scheme. Be sure to place jumpers vertically
(on pins 1 and 3 or pins 2 and 4, depend ing upon channel selection). The only jumper that
you will need to place horizontally is JP4.

* T1 mode supports RB S functionality; E1 m ode supports R2 functionality. U se JP1, JP3 and

CONNECTING ADAPTER INTER-BOARD CABLES

There are three possible cables used to connect adapters: flat, crossover, and LCD. Flat cables
connect adapters with like c onnecto rs, and cross over cab les con nect the fl at cable s of adapters with
differing connector s. LCD cables apply to former Network Express products (NE2000-II, 4000,

5000) only. These cables connect the system’s liquid crystal display (LCD) to the WAN adapter

group.

CONNECTING MULTIPLE ADAPTERS

WAN an d D M a da p te r s need int e r- b o a rd cables to com munic a te with each ot he r over an i nter­board bus. (LAN, V.35, RS232 and encryption adapters never require inter-board cabling.) The
WAN adapters use either a Time Domain Multiplexing (TDM) bus, a Multiple Vendor Integration
Protocol ( MVIP) bus, or both. The DM adapters use an MVIP bus only. Each adapter has at least
one bus connector, and some (such as the PRI-23 and PRI-23/30) have both .

The following table classifies the adapters according to inter-board connector type:

All TDM and MVIP connectors, if present, are along the top of the card as shown in the System

Adapters Appendix. If you are u nsure of the locat i on of the adapte r’s co nnec tors, r efer to the adapte r

illustrations for clarification.

The type of inter-board bus (or buses) you should install depends upon your unique system
configuration. The following suggestions should help you achieve the cleanest connections:

LAN (Ethernet) (none)

V.35 (none)

RS232 (none)

ARDWARE INSTALLATION

Connecting Adapter Inter-Board Cables

If you have P RI-23/30 cards: Use an MVIP bus connection between cards whenever possible to
achieve the b e st results. This applies to both :

• multiple PRI-23/30 configurations

• PRI -23 /30 card s i n combin a tion with DM car ds

If you have only PRI-23 cards: Use a TDM bus bet wee n WAN cards and an MVIP bus to connect to
the DM. (I.e., connect all TDM connectors to other TDM connectors, and all MVIP co n ne ctors to
other MVIP connectors within th e system.)

If you have a mixture of PRI-23 cards and PRI-23/30 cards: Use both a TDM bus and an MVIP bus.
Connect all TDM connectors to other TDM connectors, and all MVIP connectors to other MVIP
connectors within th e system.

If you have BRI, PRI-8 or Expander cards: You must use a TDM bus. If you also have a DM card in
your configuration but no PRI-23 or PRI-23/30, you will need to use a crossover cable to connect the
TDM bus to the MVIP connector of the DM card.

To establish the inter-board bus, you’l l need a flat bus cabl e and possibly a crossover cable.

The flat bus cable is a 40-pin ribbon cable. The cable can have from 2 to 6 connectors, dependi ng on
the adapter configuration of the CyberSWITCH. The ribbon cable connectors are spaced
approximately 1 in ch apart t o mate wi th t he adapter c onnectors . Never cut a f lat cabl e to sho rten it .

Flat Bus (Ribbon) Cable

Some flat cables consist of a primarily grey ribbon , with a single red wire to indicate pin 1. These
are essentially the same as the flat bus cable pictured.

Interconnect all the adapters with the same connectors using one flat bus cable of an appropriate
length. If your installation combines cards that have TDM-only connectors with cards that have
MVIP-only connectors, you will need to use a crossover cable.

The crossover cable is a 12-wire ribbon cable with 40-pin connectors. You only need the crossover
cable if all the following conditions are true:

• a Digital Modem adapter is present,

• BRI-4, or PRI-8 is present, and

• no PRI-23 or PRI-23/30 is present

Notice that the crossove r cable conn e cts between two flat cables. When connecting the crossover
cable to the f lat ca ble, al ig n pi n 1 on b oth conn ect ors. Pin 1 i s ide nti fie d by an em boss ed t rian gle on

For crosso ve r cable applic ations, make absolutely sure that pin 1 (on all six connectors) is aligned
so that it i s closest to the front panel. Pin 1 is identif ied by an embossed triangle (o r arrow) on the
underside of each connector. Note that some cables may be solid grey with one red wire indicating
pin 1 (with no identifying triangles).

CONNECTING A WAN ADAPTER TO THE LCD

Note: This cable is only required for systems with an LCD (NE2000-II, 4000, 5000).

The LCD cable is a rainbow-colored cable, approximately 3/4” wide, found inside the system.
Locate the e mb ossed triangle on the LCD cable connector. This triangle points to the end of the
connector that contains pin 1.

Locate the LCD cable connector on the WAN adapter installed in slot 1. The WAN adapter's LC D
cable connector has a “1” label i ng the end of the connector that contai ns pin 1.

Connect the LC D cable to the WAN adapter in slot 1, making sure that the triangle on the LCD cab le
is at the same end as the WAN adapter's “1” label.

SUMMARY OF GUIDELINES

CABLING GUIDELINES

Now that you have attached all the inter- b o a rd cables, refer to the connector-type table and verify
that:

1. On BRI-4, PRI-8, PRI -23 and Expander adapters, all TDM bus connectors a re connected by a flat
bus cable.

2. On PRI-23/30 only configurations, all MVIP bus conne ctors are connected by a flat bus cable.
A TDM bus is not used.

3. If mixing PRI-23/30s with BRI-4s or PRI-23s, use both an MVIP bus and a TDM bus.

4. When a Digital Modem adapter is installed, it needs to connect to the bus throug h its MVIP
connection.

• If part of a PRI-2 3/30 configura ti on: the DM adapter is part of the MVIP bus.

• If part of a PRI -23 co nfigur ati on: you need two b uses: one TD M bus f or WAN car d con nec-

tions, and one MVIP bus connecting DM adapter with MVIP adapter of the PRI-23.

• If adapters with only TDM connectors are instal led (BRI-4 an d PRI-8) and if a DM adapter

is insta lled, then a cr ossover cable must interconnect the TD M and MV IP b u ses.

T

ERMINATION GUIDELINES

On MVIP adap te rs, the MVIP bus should be terminated on both ends of the bus. Ideally, it should
be terminated on the MVIP adapter closest to the CPU (usuall y the PRI adapte r). It should also be
terminated at the Digital Modem end, on the adapter farthest from the BRI, PRI, or Expander
adapter. Terminati on is enabled by jumpers on DM-8, a nd switches o n the DM-24, DM-24+ or DM­30+, as described earlier. All other MVIP jumpers/switches on all other adapters on the MVIP bus
should not be terminated.

This chapter describes acc essing yo ur Cyber SWIT CH , w hich includes:

• making proper connections

• establishing an administ ration session

• accessing Release Notes

MAKING CONNECTIONS

There are a numbe r of way s to make a connection to the system, which includ e :

• direct connection using a keyboard and mon itor

• null-modem connection using a null-modem cable and a PC wi th Carbon Copy

• remote connection us ing Telnet

• remote con nection using a modem, a remote PC, and one of the fol lowing:
a. Carbon Copy soft ware
b. PPP Dia l-Up Netw orking software

DIRECT CONNECTION

If you only n e e d to configure or manage the CyberSWITCH in a local environmen t, the simplest
access i s through a direc t connection. The CyberSW ITCH is config ured to support a PS/2 or AT­style keyboard and a VGA 15-pin monitor.

Physical C onnections:

1. Attach k e yboard plug to the keyboard connector located on the back of the CyberSWITCH.

2. Attach monitor cable to the local monitor port located on the back of the CyberSWITCH.

Note: The CSX7000 uses a breakout box for these co nnections. Refer to the Local Console

Connection description in the CSX7000 Guide. For the location of the keyboard connector
and local mon itor port for other platf orms, refer to the Hardware Overvi ew chapter.

Powering On:

1. The rear panel on the system provides an AC input power socket. Plug the standard power
cord (supplied with the system) into this power socket.

CAUTION:
Some pla t forms may have a line voltage select switch on the rear panel. If yo u are using such a
platform, make sure that this switch is set for the correct AC input power source. When
changing the line voltage select switch, make sure the AC power cord is unplugged.

2. Ensure that the POWER-ON bu tton on the CyberSWITCH is in the OF F position.

3. Ensure that the monit or and keyboard ar e connected to the proper con nectors at the rear panel .

4. Plug the power cord into a grounded electrical outlet.

NULL-MODEM CONNECTION TO A PC

If you wish to use an IBM-compatible PC to locally administer your system , you will need to
establish a null-modem connection between PC and CyberSWITCH. You will also need the
optional Man a ger diskette which inclu des Carbon Copy software. Ca rb on Copy allows you to
manage and configure your CyberSWITCH as if it were a direct connect ion, and additionally
provides a means for file transfer. Refer to the Carbon Copy discussion in the Remote Management
chapte r f or mo re inf or mation.

Physical C onnections:

1. Use a null-modem cable (with 9-pin female RS23 2 connectors) to connect the 9-pin, male RS232
port on the CyberSWITCH to the 9-pin , male RS232 port on the PC. Depending on the type of
administration console PC you use, the null modem pin-outs may vary. The following are
appropri ate connections:

2. On the PC, execute the Manager software from diskette, or install the software on your PC’s

hard disk and exe cu te from hard disk . (1 MB of free space n e e ded for instal lation.) Note that
hard disk operation is more efficient.

Note: You do not need to chan ge Carbon Copy’s port p arameter s. The default va lues are sufficient

for null-modem connection.

Powering On:

1. Verify that the line voltag e se le c t sw it c h is set for the correct AC input power source.

2. Plug the standard power cord into the CyberSWITCH’s AC input power socket.

3. Ensure that the POWER-ON bu tton on the CyberSWITCH is in the OF F position.
