The CSX400 (Figure 1) is an access device that provides Ethernet Local Area Network (LAN)
connectivity via two Ethernet Port Interface Modules (EPIMs), and offers high-speed Wide Area
Network (WAN) access to remote sites via two WAN Port Interface Modules (WPIMs). The
CSX400 supports IEEE 802.1d transparent bridging, IP and IPX routing, ISDN, Dynamic Host
Configuration Protocol (DHCP), Network Address Translation (NAT) routing, and Inverse
Multiplexing (IMUX) between Ethernet LANs across a WAN.
The CSX400 operates from a standard ac power source and the CSX400-DC operates from a dc
voltage source to meet all the requirements for installation into Telephone Central Office facilities.
About the CSX400
Figure 1 The CSX400
CSX400 Hardware
This section details the CSX400 hardware capabilities.
WAN Connection
The CSX400 supports Point-to-Point Protocol (PPP) including: Link Control Protocol (LCP),
BNCP, IPCP, IPXCP, LQM, Multilink Protocol (MP) and CHAP and PAP, ISDN-BRI and Frame
Relay protocols through one of the following WAN port interface modules (WPIMs):
• The WPIM-T1 provides a T1 interface through a front panel RJ45 port and includes a built-in
Channel Service Unit/Digital Service Unit (CSU/DSU) for direct connection to a T1 line. The
WPIM-T1 provides both Full T1 or Fractional T1 using 56 or 64 Kbps Time Slots, with a total
throughput of up to 1.544 Mbps.
CSX400 and CSX400-DC User’s Guide 5
Page 20
About the CSX400
• The WPIM-Sync provides a synchronous serial connection of up to 2.048 Mbps to external
communications equipment (e.g., a multiplexer or CSU/DSU). The WPIM-Sync uses a
subminiature 26-pin connector that supports the electrical signal interfaces listed below.
Appendix B, provides complete part number and cable pinout information for the following
electrical signal interfaces:
• EIA-RS449
• V.35
• EIA-RS232D
• X.21
• EIA-RS530
• EIA-530A
• RS530 AL T A
• RS530A AL T A
• The WPIM-DDS provides a 56 Kbps or 64 Kbps Digital Data Service (DDS) connection. The
WPIM-DDS supports remote CSU diagnostic or 64 Kbps clear channel loopback and
non-latching remote DSU diagnostic loopback.
• The WPIM-E1 provides an E1 interface through a front panel RJ45 port and includes a built-in
CSU/DSU for direct connection to an E1 line. The WPIM-E1 provides both Full E1 or
Fractional E1 using 56 or 64 Kbps Time Slots with a total throughput of up to 2 Mbps.
• The WPIM-DI provides a T1 interface through a front panel RJ45 port and includes a built-in
CSU/DSU for direct connection to a T1 line. The WPIM-DI provides both Full T1 or Fractional
T1 using 56 or 64 Kbps Time Slots and also pro vides a second Drop-and-Insert interface, which
allows more than one device, such as a PBX, to share a single T1 connection.
• The WPIM-S/T provides an Integrated Services Digital Network (ISDN) 128 Kbps Basic Rate
Interface (BRI) for the CSX400. The WPIM-S/T provides an ISDN back-up link for a remote
site or branch office when the main WPIM for a frame relay or leased line loses a connection
or becomes disabled. An NT-1 adapter is necessary for this interface in the United States.
• The WPIM-HDSL provides a connection for users in a campus environment, or ha v e access to
local subscriber loops, who want to send their data over their existing telephone lines, that may
run between floors, buildings, or other physical structures, at rates of up to 1.544Mbps. HDSL
supports line lengths of up to 3, 657 meters (12,000 feet) over 24 American W ire Gauge (AWG)
Unshielded Twisted Pair (UTP) cabling.

the desired interface. The WPIM-T1/DDS has the capabilities of both the WPIM-T1 and
WPIM-DDS.
Ethernet LAN Connection
The CSX400 provides 10 Mbps Ethernet/IEEE 802.3 support through two Cabletron Systems
Ethernet Port Interface Modules (EPIMs), which are available in a variety of media types.
Appendix A, EPIM Specifications, details the available EPIMs that can be used to configure the
CSX400 for an Ethernet connection.
FLASH EEPROMs — The CSX400 uses a FLASH Electrically Erasable Programmable
Read-Only Memory (EEPROM) that allows new and updated firmware to be downloaded in
conjunction with Cabletron Systems QuickSET or any device using BootP or TFTP protocols.
LANVIEW LEDs — Cabletron Systems LANVIEW Status Monitoring and Diagnostics System is
a troubleshooting tool that helps in the diagnosing of power failures, collisions, cable faults, and
link problems. The LANVIEW LEDs are located on the CSX400 front panel.
RESET Button — The front panel RESET button reboots the CSX400 and initializes the
processor. The RESET button also is used with the mode switches to clear NVRAM.

Optional Features
Rack Mounting Capabilities — The CSX400 can be installed in a 19-inch rack with the
included mounting brackets and screws. Refer to Chapter 6 Installation, for complete rack
mounting instructions.
Hardware Data Compression Module (CSX-COMP/ENCR) — The same industry standard
STAC Electronics Stacker LZS Compression algorithm supported by CSX400 software is made
available by an optional hardware data compression module that accelerates data compression for
the CSX400 over PPP and Frame Relay. Depending on the packet type and size, hardware data
compression provides a minimum of 2:1 data compression, giving 3 Mbps throughput on each T-1
WPIM interface. To use the hardware data compression module, compatible equipment (such as
the CSX400, CSX200, and HSIM-W6 or other vendors’ equipment which conforms to the
applicable standards), must be in use at both ends of the WAN link. When the hardware data
compression module is installed on the board, it automatically assumes the compression task from
software. There is no configuration necessary to prioritize hardware over software compression.
CSX400 Firmware Support
The CSX400 firmware supports IEEE 802.1d bridging, and IP and IPX routing, and OSI Layer 2
Inverse Multiplexing (IMUX), which allows both WAN channels to be used as a single, high
bandwidth, WAN channel. Wide Area Networking includes Point-to-Point Protocol (PPP),
Frame Relay, and ISDN. Remote access is via Full or Fractional T1, E1, Synchronous, Digital
Data Service, ISDN BRI, or HDSL connections.
This device supports industry-standard protocols, security features, compression algorithms and
network management tools to ensure interoperability with equipment from other vendors.
IEEE 802.3 Ethernet
The CSX400 provides a standard 802.3 Media Access Control (MAC) layer for Ethernet
communications. All bridging and routing protocols are supported across the Ethernet link.

• Point-to-Point Compression Control Protocol (CCP) as defined by RFC 1962
• Inverse Multiplexing (IMUX)
• Dynamic Host Configuration Protocol (DHCP) as defined by RFC 1541
• Network Address Translation (NAT) routing as defined by RFC 1631

• Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) as defined by Q.921/
Q.931
• Frame Relay Link Management Interface (LMI) as defined by ANSI T1.617 Annex D and ITU
Q.933 Annex A
• Frame Relay Data Encapsulation as defined by RFC 1490
• Frame Relay Data Compression Protocol (DCP) as defined by FRF.9
PPP is a data link layer industry standard WAN protocol for transferring multi-protocol data traffic
over point-to-point connections. With this protocol, options such as security data compression, and
network protocols can be negotiated over the connection.
Frame Relay is a packet-switching data communications protocol that statistically multiplexes
many data conv ersations o ver a single transmission link. Data compression allows Frame Relay to
negotiate compression over Frame Relay permanent virtual channels (PVCs).
ISDN BRI is a switched Data Link layer control protocol which uses digital signaling to place a
call into an ISDN network. Once the call is made, PPP is then used to transfer data.

About the CSX400
Firmware Data Compression
The STAC Electronics Stacker LZS Compression algorithm provides a minimum of 2:1 firmware
data compression for the CSX400 over PPP and Frame Relay. Firmware data compression is
supported in software on each WAN interface for line speeds of up to 256 Kbps. per WPIM, which
is equivalent to four DS0 channels. To use data compression, compatible equipment, (such as the
CSX400, CSX200, and HSIM-W6 or other vendors’ equipment which conforms to the applicable
standards), must be in use at both ends of the WAN link. This firmware method of data
compression is used as the default, if the hardware compression module is not installed.
Inverse Multiplexing (IMUX)
NOTE
Cabletron Systems products that support IMUX, such as the CSX400, HSIM-W6 and
HSIM-4T1, must exist on both ends of the WAN link for the IMUX function to work.
Both bridging and routing functions are disabled when using the IMUX function.
Cabletron Systems Inverse Multiplexing (IMUX) feature provides enhanced throughput for users
by doing each of the following:
• The IMUX function evenly distributes a data packet stream from the LAN interface through the
two WAN interfaces on the CSX400. Since the data traffic is equally shared between the two
Full T1 interfaces, each with 1.5 Mbps throughput, the total throughput over the logical link is
3 Mbps, or 6 Mbps full-duplex operation with the optional hardware compression module
(CSX-COMP/ENCR) installed in the CSX400.
• The IMUX function passes packet sequence information over the WAN using the Point-to Point
Protocol (PPP) and a WAN Encapsulated Ethernet Frame Type to support data coherency on
both ends of the link.
• Data packet streams received by the WAN Interfaces on the CSX400 at the other end of the
WAN link are then recombined, ordered, and transmitted to the Ethernet 1 interface.
• The IMUX function is fully configurable using QuickSET, which is discussed in the Bridging
and Routing Configuration section of Chapter 7 and the MIB Navigator command set in
Chapter 9.

About the CSX400
HDLC
Cabletron Systems has provided the High-level Data Link Control (HDLC) protocol which is used
in conjunction with the Inverse Multiplexing (IMUX) feature and the WPIM-HDSL to conserve a
user’s WAN bandwidth between two Cabletron Systems products, over a point-to-point
connection. Cabletron Systems products such as the CSX400, CSX200, and HSIM-W6 must be in
use on both ends of the WAN link for these functions to work. The HDLC (RAW) protocol reduces
the amount of overhead information that needs to be contained within each data packet to direct it
to its destination. This decreased packet overhead provides the IMUX and HDSL functions with
more bandwidth to transfer user data.
DHCP and NAT
The Dynamic Host Configuration Protocol (DHCP) and Network Address Translation (NAT)
method eliminates the expense of purchasing limited public IP addresses for each client on a local
network, and the need to re-configure a client if it is moved to a different network.
The CSX400 acts as a DHCP server that allows individual clients (PCs, network equipment) to
take turns using a range of private IP addresses (often referred to as local IP addresses), and
provides optional secondary setup features for these clients on a per-port basis. The CSX400
distributes these addresses dynamically assigning a local IP address to an individual client from a
range of 253 available addresses in its table on a first-come-first-served basis. This local IP address
is then “leased” for a predetermined amount of time, which is configured for the particular port.
Each Ethernet port provides DHCP services for one Class C subnet and secondary setup features
for individual clients that support the use of a default gateway, domain name and WINs server.
On the Wide Area Network (WAN) side, the Network Address Translation (NAT) routing method
is used to enable clients assigned with local IP addresses to use the public IP address(es) of the
CSX400 WAN interface(s) to access the WAN.
NOTE
A private or “local” network is referred to as a sub network that is using private or
“local” IP addresses. An “outside” network refers to a Wide Area Network (WAN)
commonly known as an Internet, an intranet is an “Internet” in use on a facility or
campus where registered public IP addresses are required.
CSX400 and CSX400-DC User’s Guide 11
Page 26
About the CSX400
The NAT method allows several DHCP clients on a sub network to connect to WAN clients by
allowing the DHCP clients to share a single public IP address. When the CSX400 uses NAT, the
NAT method modifies the IP headers and addresses, and the selected fields in upper layer protocol
headers. This is done to replace the hidden local IP addresses from the sub network with one or
more public InterNic assigned IP addresses that can be sent over the outside network on the
CSX400 WAN interfaces. Once the CSX400 is assigned at least one public IP address, over 250 IP
clients can share this address simultaneously using NAT. This public IP address is assigned
statically by the Internet Service Provider (ISP).
Point-to-Point Protocol (PPP)
PPP is a data link layer industry standard WAN protocol for transferring multi-protocol data traffic
over point-to-point connections. It is suitable for both high-speed synchronous ports as well as
lower speed asynchronous dial-up ports. With this protocol, options such as security and network
protocols can be negotiated over the connection.
This device supports synchronous PPP over the ISDN port. In Single Link Mode, PPP uses one
ISDN B channel for data transmission. PPP runs over each ISDN B channel for two separate
conversations (split B-channel). In Multi-Link Protocol Mode, PPP simultaneously sends and
receives data over two ISDN B-channels on the same connection to optimize bandwidth usage.
The STAC Electronics Stacker LZS Compression Protocol is supported over PPP providing up to
4:1 data compression.
PAP and CHAP Security
The CSX400 supports the Password Authentication Protocol (PAP) and Challenge Handshake
Authentication Protocol (CHAP) under PPP.
PAP provides verification of passwords between devices using a 2-way handshake. One device
(peer) sends the system name and password to the other device (authenticator). Then the
authenticator checks the peer’s password against the configured remote peer’s password and
returns acknowledgment.
CHAP is more secure than PAP as unencrypted passwords are not sent across the network. CHAP
uses a 3-way handshake and supports full or half-duplex operation.
12 CSX400 and CSX400-DC User’s Guide
Page 27
About the CSX400
In half-duplex operation, the authenticator device challenges the peer device by generating a
CHAP challenge, and the challenge contains an MD5 algorithm with a random number that has
your encrypted password and system name. The peer device then applies a one-way hash
algorithm to the random number and returns this encrypted information along with the system
name in the CHAP response. The authenticator then runs the same algorithm and compares the
result with the expected value. This authentication method depends upon a password or secret,
known only to both ends locally.
Full-duplex operation places an additional step to the half-duplex operation that mirrors the
operation discussed above for a peer to validate the authenticator. The peer device challenges the
authenticator by generating a CHAP challenge, and the authenticator returns a CHAP response.
The peer device challenges the authenticator device by generating a CHAP challenge, and the
challenge contains an MD5 algorithm with a random number that has your encrypted password
and system name. The authenticator device then applies a one-way hash algorithm to the random
number and returns this encrypted information along with the system name in the CHAP response.
The peer device then runs the same algorithm and compares the result with the expected value.
This authentication method depends upon a password or secret, known only to both ends locally.
LQM
Link Quality Monitoring (LQM) is a link control mechanism used with PPP to determine when
and how often a link is dropping data in units of packets and octets. Link Quality Monitoring
accomplishes this by providing Link-Quality-Reports to determine if the quality of the link is
adequate for operation. Link Quality Monitoring provides separate measurements for both
incoming and outgoing packets that are communicated to both ends of the link. The PPP LQM
mechanism carefully defines the Link-Quality-Report packet formats, and specifies reference
points for all data transmission and reception measurements. The LQM implementation maintains
successfully received packet and octet counts, and periodically transmits this information to its
peer using Link-Quality-Report packets.
Multilink Protocol
Multilink Protocol (MP) is an extension of PPP that controls the way frames are transferred across
several links whenever a single link is not sufficient to meet the requirements of your present
traffic load. Multilink Protocol establishes sev eral simultaneous links between two end points o v er
switched circuits (dial-up lines) in an ISDN network, and dynamically adjusts the bandwidth
demands between available links to maintain an effective data transfer.

ISDN
ISDN provides an inexpensive switched digital access to remote sites. The ISDN BRI standard
provides for two high speed 64 Kbps bearer (B) channels used for voice or data connections and
one 16 Kbps signaling data (D) channel used for call setup, signaling and other information. ISDN
allows all types of information to be transmitted including voice, data, fax and video. Multiple
devices can be linked to a single ISDN connection, each having their own telephone number. Two
or more channels can be combined into a single larger transmission pipe offering variable
transmission speeds.
The CSX400 supports one ISDN BRI line and either or both of the B channels for transferring
data. If the two B channels are used for separate connections, each provides up to 64 Kbps transfer
rates. Both channels can be used together to provide uncompressed data transfer at up to 128 Kbps.
The CSX400 can also transfer compressed data at up to 512 Kbps.
A Network Terminator device (NT1) provides the interface between ISDN terminal (router)
equipment and the ISDN service provider. In the U.S., the NT1 is provided by the customer;
outside the U.S., the NT1 is provided by the ISDN service provider. The CSX400 supports the
WPIM-S/T by providing an S/T interface that requires an external NT1.
Telephone Switch Support
The following telephone switch types are supported within the U.S.:
• National ISDN 1 (NI-1)
• AT&T 5ESS with Custom Software
• DMS-100
Outside of the U.S. the following switch types are supported:
• NET3 (European ISDN)
• NET3SW (European Swiss-variant)
• NTT (Nippon Telegraph and Telephone)
• KDD (Kokusai Denshin Denwa Co., Ltd.)
• French Delta (VN4) switches

ISDN Back-up
The ISDN back-up feature provides a back-up link for a remote site or branch office when one or
more primary WAN interfaces for a frame relay circuit or a nailed-up PPP connection fails. The
WPIM-S/T serves as the backup medium for this primary connection. The WPIM-S/T uses the
ISDN interfaces to back-up any primary interfaces which hav e been configured for ISDN back-up.
Time to Connect, Time to Disconnect, Connect Retries, Back-up Override, Input Idle Time-out
and Output Idle Time-out, are the six back-up parameters used to manage the ISDN Back-up
feature on the CSX400, and are described as follows:
Time to Connect — Time to Connect allows you to configure the amount of seconds the primary
interface can be in a failed state, before attempting to switch over to the back-up interface.
Time to Disconnect — Time to Disconnect allows you to configure the amount of seconds the
restored primary interface must remain connected, before attempting to switch over from the
back-up interface.
Connect Retries — Connect Retries allows you to configure the number of tries to restore the
back-up interface, before giving up.
Backup Override — Backup Override forces the back-up interface to remain connected, and
does not allow the back-up interface to switch back to the primary interface, even if the primary
interface is restored.
Input Idle Time-out — Input Idle Time-out allo ws you to determine the amount of time necessary
for data packets to be received, before the interface is automatically disconnected.
Output Idle Time-out — Output Idle Time-out allows you to determine the amount of time
necessary for data packets to be transmitted, before the interface is automatically disconnected.

HDSL
High-bit rate Digital Subscriber Line (HDSL) technology uses existing copper twisted pair cables
designed for conventional analog voice transmission from a telephone carrier servicing area as a
low-cost alternative to the quality and speed of fiber optic cables, and provides high-speed
full-duplex digital transmission links of up to 1.544 Mbps. The WPIM-HDSL is easy to install in
your network over existing telephone lines, and it is a portable investment if a business, or
individual user plans to relocate.
HDSL is a direct connection technology that allows connections to be made for distances of up to
12,000 feet over 24 American Wire Gauge (AWG) unconditioned Twisted Pair wire. To obtain the
Full T1 line Rate of 1.544 Mbps, two wire pairs are necessary (four wires). If one pair of wires is
used (two wires), then data rates of 772 Kbps are supported, which is equivalent to one-half of a
T1 line.
Bridging and Routing
Bridging — Bridging connects two or more separate networks together. The bridge examines a
portion of each network frame called the header. This header contains control information for the
frame. The bridge compares the destination address of the frame to a table of source addresses
(bridges dynamically learn the physical location of devices by logging the source addresses of
each frame and the bridge port the frame was received on in the source address table). In
transparent bridging, the decision to forward the frame is based on this comparison. If the address
indicates that the sending station and the destination station are on the same side of the bridge, the
frame is not forwarded across the bridge. If the addresses do not indicate that, the bridge forwards
the broadcast frame across the bridge to the other network(s).
Bridging allows frames to be sent to all destinations regardless of the network protocols used. It
also allows protocols that cannot be routed (such as NETBIOS) to be forwarded, and optimizes
internetwork capacity by localizing traffic on LAN segments. A bridge extends the physical reach
of networks beyond the limits of each LAN segment. Filters can be used to increase network
security in bridged networks, and restrict message forwarding by using user-built address
tables (non-transparent bridging).

Page 31
About the CSX400
Routing — Routing provides a way to transfer user data from source to destination over different
LAN and WAN links using one or more network protocol formats. Routing relies on routing
address tables to determine the best path for each packet. Routing tables can be seeded (i.e.,
addresses for remote destinations are placed in the table along with network address masks and a
metric for path latency). Routing tables are also built dynamically (i.e., the location of remote
stations, hosts and networks are updated through inter-router protocols). Routing helps to increase
network capacity by localizing traffic on LAN segments and broadcasts that would result from
bridged traffic. It also provides security by isolating traffic on segmented LANs. Routing extends
the world-wide reach of networks.
CSX400 Bridging and Routing — The CSX400 can operate as a bridge, a router, or both. The
CSX400 operates as a router for network protocols that are supported when routing is enabled and
operates as a bridge when bridging is enabled. When both bridging and routing are enabled,
routing takes precedence over bridging; i.e., the CSX400 uses the protocol address information of
the packet to route the packet to the correct destination. However, if the protocol is not supported,
the CSX400 operates as a bridge and uses the MAC address information to send the packet.
Operation of the CSX400 is influenced by routing and bridging controls and filters set during
CSX400 configuration. General IP routing, and routing or bridging from specific remote routers
are controls set during the configuration process.
IEEE 802.1d Bridging — The CSX400 supports the IEEE 802.1d standard for LAN to LAN
bridging. Bridging is provided over PPP and Frame Relay as well as adjacent LAN ports. The
bridging software uses transparent bridging. When the CSX400 is configured as a bridge, the unit
bridges data packets to the destination, regardless of the network protocols used.
The CSX400 uses the Spanning Tree Algorithm to provide bridging redundancy while preventing
data loops and duplicate data. This is a self-learning bridge, i.e., the bridge builds and updates an
address table with each MAC source address and associated information when the packets are
received.
IP Routing — IP routing support provides the ability to process TCP/IP frames at the network
layer for routing. IP routing support includes the Routing Information Protocol (RIP) that allows
the exchange of routing information on a TCP/IP network. The CSX400 receives and broadcasts
RIP messages to adjacent routers and workstations.
IPX Routing — Internet Packet Exchange (IPX) routing support provides the ability to process
Novell proprietary frames at the network layer for routing. IPX routing support includes both
Routing Information Protocol (RIP) and Service Advertising Protocol (SAP) that allows the
exchange of routing information on a Novell NetWare network. The SAP provides routers and
servers containing SAP agents with a means of exchanging internetwork service information.

Bridging and Routing Protocol Filtering
Filtering is used to allow efficient usage of network resources and provide security for your
network and hosts.
IP Internet Firewall — The CSX400 supports IP Internet Firewall filtering to prevent
unauthorized access to your system and network resources from the Internet or a corporate
Intranet. Security can be configured to permit or deny IP traffic. The security is established by
configuring IP access filters, which are based on source IP address, source mask, destination IP
address, destination mask, protocol type, and application port identifiers for both Transmission
Control Protocol (TCP) and User Datagram Protocol (UDP) protocols. These IP access filters
allow individual IP source and destination pair filtering as well as IP address ranges and wild
carding to match any IP address. These Firewall filters can be defined to allow inbound only,
outbound only, or bi-directional IP communication up to the UDP and TCP application port level.
Firewall access filters provide a lot of flexibility to establish a powerful IP security barrier. The
CSX400 supports the IP Access Control (from the ctip-mib) Internet Firewall Filter.
Bridge Filtering — Bridge filtering allows a network administrator to control the flow of packets
across the CSX400. Bridge filtering can be used to “deny” or “allow” packets based on a “matched
pattern” using a specified position and hexadecimal content within the packet. This enables
restricting or forwarding of messages based on address, protocol, or data content. Common uses
include preventing access to remote networks, controlling unauthorized access to the local
network, and limiting unnecessary traffic.
The CSX400 supports the following Bridge Filters:
• dot1dStatic Filters (IETF RFC1493)
• Ethernet Special Filtering Database (from the ctbridge-mib)
System Passwords
System passwords allow you to control access to the CSX400 by establishing three passwords.
Each password provides varying levels of access to the CSX400. The default password for each
access level is pre-set to public. If you do not wish to establish a password, press ENTER, the
default password is automatically selected.
The following definitions explain each of the three levels of access:
read-only — This access level allows reading of device parameters not including system
passwords.

read-write — This access level allows editing of some device configuration parameters not
including changing system passwords.
super-user — This access level allows full management pri vile ges. At this level you must access
the CSX400 to run QuickSET.
Simple Network Management Protocol (SNMP)
The CSX400 provides SNMP agent support for the following: standard and Enterprise Specific
Management Information Bases (MIBs), and support for standard and Enterprise Specific SNMP
Traps. SNMP is also used internally for configuration of the CSX400. The active SNMP agent
within the CSX400 accepts SNMP requests for status, statistics and configuration updates.
Communication with the SNMP agent occurs over the LAN or WAN connection. Any
management application using SNMP over UDP/IP has access to the local SNMP agent.
SNMP MIB Support
SNMP MIBs are databases of objects used for managing and determining the status and
configuration of an SNMP compliant device.
The following SNMP MIBs are supported by the CSX400:
• MIB IIRFC1213

from your service provider (telephone company). The rest of the chapter details the information
that the service provider needs to give you, and which you need to give to the service provider.
ISDN Line Ordering and Configuration
Arranging ISDN Service
The service provider requires certain information about the capabilities of the CSX400. You must
give the service provider the required switch settings (parameters) for the provider’s central office
switch. Consult with your service provider at least two months before you require the installation
and use of the ISDN service.
Complete the following steps to arrange your ISDN service:
1. Contact the service provider and determine what type of ISDN central office switches are
available (see Telephone Switch Support in this chapter).
2. Supply the service provider with the provisioning information for their switch type to enable
proper configuration of the ISDN line (see Telephone Switch Parameters in this chapter).
3. Once the ISDN line is installed, ensure that the service provider supplies you with the following
information:
• ISDN telephone numbers
• ISDN Service Profile Identifier numbers (SPIDs) and/or Directory Numbers (DNs) (see
SPIDs, Directory Numbers and Telephone Numbers in this chapter).

ISDN Line Ordering and Configuration
Telephone Switch Support
Your telephone company may offer a variety of ISDN switch types. You must contact your service
provider and find out which type of ISDN service is available.
The following switch types are currently supported by the CSX400 within the U.S.:
• National ISDN 1 (NI-1)
• AT&T 5ESS with Custom Software
• DMS-100
Outside of the U.S. the following switch types are currently supported:
• NET3 (European ISDN)
• NET3SW (European Swiss-variant)
• NTT (Nippon Telegraph and Telephone)
• KDD (Kokusai Denshin Denwa Co., Ltd.)
• French Delta (VN4) switches
ISDN BRI Line Configuration
You need to order one Basic Rate Interface (BRI) ISDN line from your service provider. The Basic
Rate Interface ISDN line provides two full duplex 64 (Kbps) B channels used for voice, data, fax,
etc. and one full duplex 16 Kbps channel used for signaling. Each B channel can be used for a call;
i.e., two calls can occur at the same time. Services vary from individual service providers.
NOTE
The service provider requires some information from you about your configuration. You must
provide your service provider with the required switch settings for the provider’s telephone switch
(see Telephone Switch Parameters in this chapter). Consult with your service provider at least
two months before requiring the installation and use of the ISDN service.
24 CSX400 and CSX400-DC User’s Guide
Full 64 Kbps for each channel (called clear channel) may not be available across the
entire communications link. Today, many providers still use in-band signaling
(the 8 Kbps signaling is taken from the B channel bandwidth) so that you may only
achieve a 56 Kbps channel speed.
Page 39
ISDN Line Ordering and Configuration
In the U.S. and Canada, Network Terminator equipment (NT1) is required to provide an interface
between the CSX400 and the ISDN line. The NT1 offers conversion between the two-wire twisted
pair (U-loop interface) used by telephone companies and the four-wire terminal equipment (S/T
Interface) as well as line-testing capabilities. External Network Terminator equipment comes with
a power supply (built-in or external).
In Europe and Japan, the telephone company provides the NT1 and offers end-users the S/T
interface. The S refers to a connection between customer equipment in some ISDN configurations
when a PBX is present. The T refers to the connection between the NT1 device and the CSX400.
The ISDN pairs are the same wires that exist for analog telephone service. In most cases, the same
wires can be used for the ISDN line. The EIA/TIA standard for wiring is Unshielded Twisted Pair
(UTP) cable, Category 3 or above, 24 AWG (American Wire Gauge). The standard also
recommends using 8-position RJ45 jacks for new ISDN service installation. No special
conditioning is required; in some cases, conditioning must be removed.
ISDN BRI Configurations
ISDN BRI lines can be configured in point-to-point and multi-point configurations. With a
point-to-point configuration, only one device is connected to the ISDN line. With a multi-point
configuration, it is possible to have up to 8 devices (telephones, faxes, routers, etc.) connected to
the line.
Since the ISDN BRI line is used for a high speed LAN-to-LAN link, you must ensure that
additional devices connected to the S/T interface allow sufficient access for the bandwidth
requirements of the CSX400.
SPIDs, Directory Numbers and Telephone Numbers
The service provider gives you up to three sets of numbers for identifying the ISDN line and
devices. You may be assigned none, one or two Service Profile Identifier numbers (SPIDs) or
Directory Numbers (DNs) depending on the service provider and country.
Phone Numbers
Numbers used for others to dial into the ISDN B channels on your ISDN line (similar to analog
line phone numbers).
Directory Numbers
Address assigned by the ISDN service provider for each device operating on the line. This number
can be similar to the phone number. The Directory Number is not generally implemented outside
the U.S.
CSX400 and CSX400-DC User’s Guide 25
Page 40
ISDN Line Ordering and Configuration
Service Profile Identifiers
SPIDs, also assigned by the ISDN service provider, identify the services and features that the
telephone company switch provides to the ISDN device. Commonly implemented in the U.S. and
Canada, the SPID is often derived from the directory number, combined in a series with other
digits. SPIDs are not generally implemented outside the U.S. and Canada.
Telephone Switch Parameters
Once you have contacted your service provider and learned the type of ISDN switch being used,
refer to Table 1, Table 2, and Table 3. You must supply the appropriate provisioning information
to the service provider to ensure proper configuration of the ISDN line.
NOTE
National ISDN 1 (NI-1) is a specification released by Bellcore outlining a basic set of
ISDN services used for standardization by equipment vendors.

Planning for CSX400 ISDN Configuration
This chapter explains the CSX400 ISDN-BRI configuration process and terminology. It also
describes the information that is required for configuration.
Configuration Process and Terminology
During configuration, you specify information identifying the CSX400 and define the LAN and
WAN connections of the CSX400. All of the remote routers to which this device may connect are
added to a database called the remote router database that resides in the CSX400. Each remote
router entry in the database defines the connection parameters, security features, route addressing
and bridging function for the remote router (see the example in Figure 2). Routing and bridging
are controlled by specific remote router entry information as well as general controls that are set
after all other information is configured.

Collect Network Information
Before you begin, you need to obtain information about the network to which you are adding the
CSX400. Some of the information is obtained from your central site or remote site network
administrator. Other information is obtained from your ISDN service provider.
You must define the name and security password of the CSX400, ISDN line information and the
Ethernet LAN IP and/or IPX address. You need to identify all of the remote routers and their
routing and bridging capability, ISDN phone numbers, addressing and security information. You
also need to decide whether you will use Internet Firewall Filtering if you are using IP routing. The
following sections contain diagrams and tables to help you gather and organize the information.
Names and Passwords
You must choose a name for the CSX400 and the authentication password, both of which are used
by a remote site to authenticate the target router. For each remote router, you must have the router
name and its authentication password which is used by the CSX400 to authenticate the remote
router. The name and password are used in both PAP and CHAP authentication. Figure 3 shows
how this information is used.

ISDN Line Information
You need to know the telephone switch type and phone numbers associated with the ISDN line.
The telephone switch types supported are listed in Telephone Switch Support. The service
provider gives you up to three sets of numbers for identifying the ISDN line and attached devices.
You may be assigned none, one or two SPIDs or DNs and this varies by service provider and
country.
Phone Numbers — Numbers used for others to dial into the ISDN B channels on your ISDN line
(similar to analog line phone numbers).
Directory Numbers — Address assigned by the ISDN service provider for each device operating
on the line. This number can be similar to the phone number. The Directory Number is not
generally implemented outside the U.S.
Service Profile Identifications — SPIDs, also assigned by the ISDN service provider, identify
the services and features that the switch provides to the ISDN device. Commonly implemented in
the U.S. and Canada, the SPID is often derived from the directory number, combined in a series
with other digits as shown in the example in Figure 4. SPIDs are not generally implemented
outside of the U.S. and Canada.

Network Information Diagrams
It is helpful to draw a diagram including all locations, addresses, router names, etc. This section
includes diagrams needed to configure the CSX400. You may need different addressing
information depending on whether you are configuring IP routing and/or NetWare IPX routing.
NOTE
to configure both ends of the WAN link, you should label all information for the network.
TCP/IP Routing — An IP address and subnet mask are required for the Ethernet LAN for the
router connection. Each remote router ISDN WAN link may have local and remote IP addresses
and subnet masks depending on the type of IP addressing as shown in Figure 5. The IP routing
table in the CSX400 can be “seeded” with addressing information for networks/stations beyond
the remote router.

Planning for CSX400 ISDN Configuration
TCP/IP Route Addresses — If the CSX400 is to direct traffic to networks or stations beyond the
remote router, the routing table in the CSX400 can be “seeded” with static IP routes. An IP route
includes an IP address, subnet mask and metric. The metric is a number representing the perceived
cost in reaching the remote network or station.
The CSX400 routing table must be seeded statically so that it dials out to the appropriate remote
router when IP traffic is targeted to networks and stations be yond that remote router. After the link
is established, RIP update packets are dynamically added to the routing table. Seeding the routing
table is not necessary when the CSX400 never dials out; it discov ers remote netw orks and stations
beyond the calling router as soon as RIP updates arrive (provided the remote router supports RIP
and RIP packets are allowed to flow on the WAN link).
TCP/IP Default Route — One default route should be designated in the routing table for all
traffic that cannot be directed to other specific routes. You need to define the default route for a
remote router if the CSX400 will be placing calls to that remote router.
Source (Target) and Remote WAN IP Addresses — Y ou may need to specify a Source WAN IP
address and/or a Remote WAN IP address for the WAN connection to the remote router depending
on IP address negotiation under PPP. Check with your system administrator for details on whether
the router must communicate in numbered or unnumbered mode and what addresses are required.
In unnumbered mode, neither IP address is defined on the link. In numbered mode, one IP address
is defined on each end of the WAN link. These addresses may or may not belong to the same
subnetwork. They may also be determined automatically, negotiated, or forced by the network
administrator.
The CSX400 automatically determines whether to run in unnumbered mode or numbered mode. If
unnumbered mode negotiation fails, numbered mode is attempted using the Ethernet LAN IP
address as a default. If you have specified a Source WAN IP address, unnumbered mode
negotiation is not performed; i.e., the operating mode is numbered. If a Source WAN IP address is
explicitly defined, the router will not, as a rule, accept another local address from the remote end.
In numbered mode without an explicit Source WAN IP address, this address can be negotiated to a
different value by the remote end.
CSX400 and CSX400-DC User’s Guide 33

NetWare IPX Routing — An Ethernet LAN IPX network number is required for the CSX400
local Ethernet LAN connection. The ISDN WAN link to each remote router must have an assigned
IPX network number. IPX Routes and IPX SAPs for each remote router are also required for the
configuration process. Figure 9 provides an example of the network layout for IPX routing.

IPX Routes — If the CSX400 is to direct traffic to network segments and servers beyond the
remote router, the routing table in the CSX400 can be “seeded” with static IPX routes. An IPX
route includes a network number, hop count and ticks. The hop count is the number of routers
through which traffic must pass to reach the remote network segment or server. Ticks represent
how much time the packet takes to reach the destination in roughly 1/18th of a second increments.
The CSX400 routing information table must be seeded statically so that it dials out to the
appropriate remote router when IPX traffic is targeted to network segments or servers beyond that
remote router. After the link is established, RIP update packets dynamically add to the routing
information table in the CSX400. Seeding the routing table is not necessary when a CSX400 never
dials out; it will discover routes beyond the calling router as soon as RIP updates arrive (provided
the remote router supports RIP).
IPX SAPs — If the CSX400 is to obtain services beyond the remote router, the CSX400 SAP
services table must be seeded statically. A SAP service is identified by a server name and
corresponding server type, network number, node number and socket. The socket number
represents the service (application) within the server node.
The CSX400 SAP services table must be seeded statically so that the device can direct traffic to the
appropriate remote router when a service is requested from a server beyond that remote router.
After the link is established, SAP broadcast packets dynamically add to the target router services
table. Seeding the table is not necessary when a CSX400 never dials out; it will discover remote
services beyond the calling router as soon as SAP broadcasts arrive (provided the remote router
supports IPX).
IPX Network Numbers — IPX network numbers are assigned to LAN network segments as well
as servers. These numbers should be unique for all IPX networks on the Internetwork.
IPX external network numbers refer to the physical LAN network segments to which servers and
routers are connected. The WAN link network number is an external IPX network number. This is
a unique number that you choose (or are given by the network administrator) to represent the WAN
link between the CSX400 and remote router. The local Ethernet IPX network number is also an
external network number.
Servers are identified with internal network numbers. This is a logical network number that
identifies the individual server. For a local router to access a server beyond the remote router, you
specify a route using the internal network number of a server. To seed the routing table to access a
network segment, you specify the external network number of the LAN segment. The network
number in the SAP table is the internal network number of the server.
CSX400 and CSX400-DC User’s Guide 37
Page 52
Planning for CSX400 ISDN Configuration
Node Numbers — Servers can have internal and external node numbers. The internal node
number is a logical number assigned by the system administrator to the server. The external node
number is the MAC address of the server. When adding SAP services to the SAP table, internal
node numbers are used.
Network Information Tables
The following tables list the items you need to define or obtain to configure the router. This
information is illustrated in the network information diagrams and described in the previous
sections. Worksheets are provided in Chapter D, so that you can enter details about your CSX400
and remote routers. Table 4 provides information for configuring your system settings, Table 5
explains the Remote Router Database configuration settings and Table 6 details bridging and
routing configuration.

Names and Passwords Example
In the sample configuration provided in Table 11, a small office FP2 communicates with a central
site FP3 and an Internet Service Provider ISP. As indicated in this example, router FP2 has a
system password “FP2passwd”. This password is used when FP2 dials out to site FP3 for
authentication by that site, and at any time when FP3 challenges FP2. FP3 has a system password
“FP3passwd” which is, likewise, used when FP3 dials out to site FP2 for authentication by FP2,
and at any time FP2 challenges FP3. The ISP site has a system password “ISPpasswd” used for the
same purpose.
Each router includes the remote router password in the definition of any remote site to which it
communicates. The router will use the remote password to authenticate the remote site when the
remote router dials in or is challenged by the local site. For example, FP2 has remote router entries
for FP3 and ISP, and defined in each entry are the respective remote router password.
The following table shows the names and passwords for each router that must be defined for
authentication to be performed correctly. (This assumes that all three systems use some form of
authentication protocol.)

This chapter contains general networking guidelines. Before attempting to install the CSX400 or
any additional EPIMs or WPIMs, review the requirements and specifications outlined in this
chapter.
NOTE
Ethernet Cabling Requirements
Your network installation must meet the conditions, guidelines, specifications, and
requirements included in this chapter to ensure satisfactory performance of this
equipment. Failure to follow these guidelines may result in poor network performance.
Network Requirements
Take care in planning and preparing the cabling and connections for your network. The quality of
the connections, the length of cables, and other conditions of the installation play critical roles in
determining the reliability of your network.
This chapter contains general guidelines for the following:
• 10BASE-T Twisted Pair Network
• Multimode Fiber Optic Network
• Single Mode Fiber Optic Network
• 10BASE2 Coaxial Cable Network
• Transceiver Requirements
Refer to the following sections that apply to your specific network configuration.
CSX400 and CSX400-DC User’s Guide 49
Page 64
Ethernet Cabling Requirements
10BASE-T Twisted Pair Network
When connecting a 10BASE-T segment to either of the CSX400 Ethernet interfaces (Twisted Pair
Ethernet Port Interface Module [EPIM-T]), ensure that the network meets the following
requirements:
Length — The IEEE 802.3 10BASE-T standard requires that 10B ASE-T de vices transmit o ver a
100 meter (328 foot) link using 22–24 AWG unshielded twisted pair wire. However, cable quality
largely determines maximum link length. If you use high quality, low attenuation cable, you can
achieve link lengths of up to 200 meters. Cable delay limits the maximum link length to 200
meters.
Losses introduced by connections at punch-down blocks and other equipment reduce
NOTE
Insertion Loss — Between frequencies of 5.0 and 10.0 MHz, the maximum insertion loss must
not exceed 11.5 dB. This includes the attenuation of the cables, connectors, patch panels, and
reflection losses due to impedance mismatches in the link segment.
Impedance — Cabletron Systems 10BASE-T products work on twisted pair cable with
75-to-165 ohms impedance. Unshielded twisted pair cables typically have an impedance of
between 85 and 110 ohms. You can also use Shielded Twisted Pair cables, such as IBM Type 1
cable, but this cable has an impedance of 150 ohms.
total segment length. For each connector or patch panel in the link, subtract 12 meters
from the total length of the cable.
Jitter — Intersymbol interference and reflections can cause jitter in the bit cell timing, resulting
in data errors. 10BASE-T links must not generate more than 5.0 ns of jitter. Make sure the cable
meets 10BASE-T link impedance requirements to rule out jitter as a concern.
Delay — The maximum propagation delay of a 10BASE-T link segment must not exceed
1000 ns. This 1000 ns maximum delay limits the maximum link segment length to no greater than
200 meters.
Crosstalk — Signal coupling between different cable pairs within a multi-pair cable bundle
causes crosstalk. 10BASE-T transceiver design alleviates concerns about crosstalk, provided the
cable meets all other requirements.
50 CSX400 and CSX400-DC User’s Guide
Page 65
Ethernet Cabling Requirements
Noise — Crosstalk, or externally induced impulses, can cause noise. Impulse noise may cause
data errors if the impulses occur at very specific times during data transmission. Generally , noise is
not a concern. If you suspect noise-related data errors, you may need to reroute the cable or
eliminate the source of the impulse noise.
Temperature — Multi-pair PVC 24 AWG telephone cables typically have an attenuation of
approximately 8–10 dB/100 m at 20°C (68°F). The attenuation of PVC insulated cable varies
significantly with temperature. At temperatures greater than 40°C (104°F), Cabletron Systems
strongly recommends using plenum-rated cable to ensure attenuation remains within specification.
Multimode Fiber Optic Network
When connecting a multimode fiber optic link segment to the CSX400 (using an EPIM-F1/F2),
ensure that the network meets the following requirements:
Cable T ype — Use the following multimode fiber optic media:
• 50/125 µm fiber optic cabling
• 62.5/125 µm fiber optic cabling
• 100/140 µm fiber optic cabling
Attenuation — Test the fiber optic cable with a fiber optic attenuation test set adjusted for an
850 nm wavelength. This test verifies that the signal loss in a cable falls within the following
acceptable levels:
• 13.0 dB or less for a 50/125 µm fiber cable segment
• 16.0 dB or less for a 62.5/125 µm fiber cable segment
• 19.0 dB or less for a 100/140 µm fiber cable segment
CSX400 and CSX400-DC User’s Guide 51
Page 66
Ethernet Cabling Requirements
Budget and Propagation Delay — When you determine the maximum fiber optic cable length
to incorporate fiber runs into the network, calculate and consider the fiber optic budget (a total loss
of 11.0 dB or less is permissible between stations) and total network propagation delay.
To determine the fiber optic budget, combine the optical loss due to the fiber optic cable, in-line
splices, and fiber optic connectors. Typical loss for a splice and connector (together) equals
1 dB or less.
Network propagation delay is the amount of time it takes a packet to travel from the sending
device to the receiving device. Total propagation delay allowed for the entire network must not
exceed 25.6 µs in one direction (51.2 µs round trip). If the total propagation delay between any
two nodes on the network exceeds 25.6 µs, you must use bridges or switches.
Length — The maximum possible multimode fiber optic cable length is 2 km (1.24 miles).
However, IEEE 802.3 FOIRL specifies a maximum of 1 km (0.62 miles).
Single Mode Fiber Optic Network
When connecting a single mode fiber optic link segment to the CSX400 (using an EPIM-F3),
ensure that the network meets the following requirements:
Cable T ype — Fiber optic link segments should consist of 8/125 or 12/125 µm single mode fiber
optic cabling. You can also use 62.5/125 µm multimode cable with the EPIM-F3; however,
multimode cable allows for greater optical loss, and limits the possible distance to 2 km.
Attenuation — Test the fiber optic cable with a fiber optic attenuation test set adjusted for a
1300 nm wavelength. This test verifies that the signal loss in a cable falls within the acceptable
level of 10.0 dB or less for any given single mode fiber optic link.
Budget and Propagation Delay — When you determine a maximum fiber optic cable length,
you must calculate and consider the fiber optic budget (a total loss of 10.0 dB or less between
stations) and total network propagation delay.
To determine the fiber optic budget, combine the optical loss due to the fiber optic cable, in-line
splices, and fiber optic connectors. Typical loss for a splice and connector (together) equals 1 dB
or less.
Network propagation delay is the amount of time it takes a packet to trav el from the sending device
to the receiving device. Total propagation delay for the entire network must not exceed 25.6 µs in
one direction (51.2 µs round trip). If the total propagation delay exceeds 25.6 µs, you must use
bridges or switches to re-time the signal.
52 CSX400 and CSX400-DC User’s Guide
Page 67
Ethernet Cabling Requirements
Length — If your network meets all system budgets, the maximum single mode fiber optic cable
length can reach 5 km (3.1 miles) with bridges or switches at each segment end. The FOIRL
specifies a maximum of 1 km (0.62 miles).
10BASE2 Coaxial Cable Network
When connecting a thin coaxial cable segment to the CSX400 (using an EPIM-C), ensure that your
network meets the following requirements:
Cable T ype — Use only 50-ohm RG 58A/U type coaxial cable for thin coaxial cable segments.
Length — The thin coaxial cable segment must not exceed 185 meters.
Terminators — Terminate each end of a thin coaxial cable segment.
Connectors — You can use up to 29 T-connectors throughout the length of the cable segment for
host connections. Ensure that all connections are spaced 0.5 meters or more from one another or
from terminators.
If you use an excessive number of barrel connectors within the cable segment (e.g., finished wall
plates with BNC feed-throughs), you may need to reduce the number of host connections. For
special network design information, contact Cabletron Systems Technical Support.
Grounding — For safety, ground only one end of a thin coaxial cable segment. Do NOT connect
EPIM BNC ports to earth ground.
Connecting a thin coaxial cable segment to earth ground at more than one point could
produce dangerous ground currents.
!
CAUTION
Transceiver Requirements
When you connect an external network segment to an EPIM-A in your CSX400 through a
transceiver, that transceiver must meet IEEE 802.3 standards or Ethernet version 1.0 or 2.0
requirements. The transceiver must also have SQE disabled.

Connecting the CSX400 to the Power Source
NOTE
The CSX400 has a universal power supply. This allows you to connect the CSX400 to
power sources of 100–125 and 200–240 Vac, 50/60 Hz.
To connect the CSX400 to the power source, perform the following steps:
1. Plug the power cord into the back panel of the CSX400.
2. Plug the other end of the power cord into a grounded wall outlet.
3. Verify that the PWR LED is on, indicating that the CSX400 is receiving power. After the
CSX400 runs a self test, the CPU LED blinks green indicating normal operation. If the LED
remains red, the processor is faulty; contact Cabletron Systems Technical Support (refer to
Getting Help in Chapter 1.)
4. Proceed to Chapter 7 to configure the CSX400.

Connecting the CSX400-DC to the Power Source
Th CSX400-DC requires either a 48 Vdc or 60 Vdc (48/60 Vdc), 3.5 A (maximum), e xternal power
source supplied by three 18 AWG (American Wire Gauge) copper wires. These wires must be
terminated to the dc input power strip shown in Figure 20 with either ring or spade terminals. The
dc power supply in the CSX400-DC has its own on/of f switch and is rated at 100 watts. To connect
the CSX400-DC to a 48/60 Vdc power source, face the back panel, then refer to Figure 20 and
proceed as follows:
ONLY QUALIFIED PERSONEL SHOULD PERFORM THESE INSTALLATION
PROCEDURES.
TO REDUCE THE RISK OF ELECTRIC SHOCK OR ENERGY HAZARDS:
• CONNECT TO A RELIABLY GROUNDED 48/60 VDC SELV SOURCE.
• ENSURE THE BRANCH CIRCUIT OVERCURRENT PROTECTION IS
RATED AT A MIMINUM OF 10 A.
• USE 18 AWG SOLID COPPER CONDUCTORS ONLY.
• ENSURE THAT A READILY ACCESSIBLE DISCONNECT DEVICE THAT IS
SUITABLY APPROVED AND RATED, IS INCORPORATED IN THE FIELD
