Chapter 2: About the HSIM-W6
Optional Feature
Hardware Data Compression Module (CSX-COMP/ENCR) — The same industry standard
STAC Electronics Stacker LZS Compression algorithm supported by HSIM-W6 software is made available by an optional hardware data compression module that accelerates data compression for the HSIM-W6 over Nailed-up PPP or ISDN 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 HSIM-W6, CSX200, and CSX400 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.
HSIM-W6 Firmware Support
The HSIM-W6 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.
WAN Protocols
This device supports the following WAN protocols over the WAN port:
• Point-to-Point Compression Control Protocol (CCP) as defined by RFC 1962
• Point-to-Point Protocol (LCP) as defined by RFC 1661
• Point-to-Point Protocol (BNCP) as defined by RFC 1638

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 conversations over a single transmission link. Data compression allows Frame Relay to negotiate compression over Frame Relay permanent virtual circuits (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.
HSIM-W6 Installation Guide 2-5
Chapter 2: About the HSIM-W6
Inverse Multiplexing
NOTE
Cabletron Systems products that support Inverse Multiplexing (IMUX), such as the
HSIM-W6, CSX400, and HSIM-W84, 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 HSIM-W6. 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 HSIM-W6.
• The IMUX function passes packet sequence information over the WAN using the Point-to-Point
Protocol (PPP) to support data coherency on both ends of the link.
• Data packet streams received by the WAN interfaces on the other end of the WAN link are then recombined, ordered, and transmitted to the LAN interface.
• The IMUX function is fully configurable using QuickSET, which is discussed in the
QuickSet Configuration Guide.
Firmware Data Compression
The STAC Electronics Stacker LZS Compression algorithm provides a minimum of 2:1 firmware data compression for the HSIM-W6 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
HSIM-W6, CSX400, and CSX200 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.

HSIM-W6 Firmware Support
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 HSIM-W6, CSX200, and CSX400 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 HSIM-W6 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 HSIM-W6 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 an predetermined amount of time, which is configured for the particular port.
The Ethernet port provides DHCP services for one Class C subnet and secondary setup features for individual clients 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
HSIM-W6 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 where registered public IP addresses are required.
HSIM-W6 Installation Guide 2-7
Chapter 2: About the HSIM-W6
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 HSIM-W6 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
HSIM-W6 WAN interfaces. Once the HSIM-W6 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).
Frame Relay Protocol
Frame Relay can be defined as a “packet mode” service, organizing data into individually addressed units known as “frames”. Frame Relay eliminates all Layer 3 processing. Only a few
Layer 2 functions are used, such as checking for a valid, error free frame, but not requesting retransmission if an error is found. Frame Relay uses a variable length framing structure, which, depending on user data, can range from a few to more than a thousand characters.
A Frame Relay Network will often be depicted as a cloud, because the Frame Relay Network is not a single physical connection between one endpoint and another. Frame Relay protocol is based on the concept of Virtual Circuits (Vcs). Vcs are two-way, software defined data paths between two ports that take the place of private lines in the network. There are two types of Frame Relay connections; Switched Virtual Circuits (SVCs), and Permanent Virtual Circuits (PVCs).
Permanent Virtual Circuits, or PVCs, are set up via a network management system, and initially defined as a connection between two sites, or endpoints. PVCs may be added as the demand arises for more bandwidth, alternate routing, or more sites. PVCs are fixed paths, not available on demand, or on a call-by-call basis. Although the actual path through the network may change from time to time, such as when automatic rerouting takes place, the beginning and end of the circuit will not change.
Switched Virtual Circuits, or SVCs, are available on a call-by-call basis using the SVC signaling protocol (Q.933). The network must quickly establish the connection, and allocate bandwidth based on the user’s request.
In a Frame Relay frame, user data packets are not changed in any way. A two byte header is appended to the frame. Contained in this header is a 10-bit number called the Data Link
Connection Identifier (DLCI). The DLCI is the “virtual circuit” number which corresponds to a particular destination. The DLCI allows data coming into a Frame Relay switch to be sent across the network using a three-step process: Check the integrity of the frame and discard it if it is in error, look up the DLCI in a table and if not intended for this link, discard the frame. If the frame passes the previous tests, relay the frame toward its destination out the specific port specified in the table.
2-8 HSIM-W6 Installation Guide
HSIM-W6 Firmware Support
The ANSI standard defines a mechanism for the network to signal the existence of congestion, called Explicit Congestion Notification (ECN) bits. Frame Relay uses FECN (Forward ECN) and
BECN (Backward ECN) bits to notify end user devices about network congestion. Although the
Frame Relay protocol does not respond to congestion, some higher layer protocols for end user devices may respond to ECNs by recognizing that delays have increased, or that frames have been dropped.
Point-to-Point Protocol
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 HSIM-W6 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.
HSIM-W6 Installation Guide 2-9
Chapter 2: About the HSIM-W6
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 the 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 the 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.

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 cannot handle the present traffic load. Multilink Protocol establishes several simultaneous links between two end points over 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 HSIM-W6 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 HSIM-W6 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 HSIM-W6 supports the
WPIM-S/T that provides an S/T interface requiring 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 w/Custom Software
• DMS-100
Outside of the U.S. the following switch types are supported:
• NET3 (European ISDN)
• NET3SW (European Swiss-variant)

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 have 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 HSIM-W6, and are described as follows:
Time to Connect — Time to Connect allows the user 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 the user 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 the user to configure the number of tries to bring up 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 allows the user 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 the user to determine the amount of time necessary for data packets to be transmitted, before the interface is automatically disconnected.
The IP-OSPF Routing Protocol
Open Shortest Path First (OSPF) is a link state routing protocol developed for Internet Protocol
(IP) networks. OSPF distributes routing information between routers belonging to a single autonomous system. In an autonomous system, routers exchange routing information through a common routing protocol.
OSPF was designed primarily for the Internet environment and supports variable length subnet masks, Type of Service (TOS) based routing, packet authentication, and the tagging of externally derived routing information.
2-12 HSIM-W6 Installation Guide
HSIM-W6 Firmware Support
OSPF, based upon link-state technology, was developed by the Internet Engineering Task Force
(IETF). The IETF developed OSPF based upon the shortest path first algorithm to serve large, heterogeneous networks.
A key feature of OSPF is the speed in which it responds to topological changes, commonly referred to as “convergence time.” OSPF generates a minimal amount of routing protocol traffic compared to most distance vector protocols.
Cabletron’s implementation of OSPF is based on RFC 1247 — OSPF Version 2 and RFC 1253 —
OSPF Version 2 Management Information Base.
IP-OSPF Hierarchy
IP-OSPF operates within a hierarchy of entities:
Autonomous System
An Autonomous System (AS) is a set of routers and networks under a common administration.
Routers inside an AS are called “interior gateways” and the protocol is called Interior Gateway
Protocol (IGP). OSPF is an IGP.
Every OSPF routing domain must have a backbone. An OSPF backbone distributes routing information between areas in an OSPF routing domain. The backbone of an OSPF routing domain system is an OSPF area possessing an area id of 0.0.0.0.
Areas
Areas are groups of networks and attached hosts. A router’s topology database includes area links, and summarized and external links depicting the autonomous system topology. From this database, routers calculate a route using the shortest-path tree algorithm.
The Hello Protocol
The Hello Protocol establishes and maintains neighbor relationships, and ensures bidirectional communications among neighboring routers. Hello packets are sent out all router ports periodically. A designated router is chosen by the Hello Protocol on multi-access networks and controls adjacencies formed over the network.
Neighbors and Adjacency
The OSPF routing protocol establishes adjacencies among neighboring routers which facilitate the exchange of routing information. Neighboring routers have interfaces to a common network and are discovered by OSPF’s Hello Protocol.
HSIM-W6 Installation Guide 2-13
Chapter 2: About the HSIM-W6
Area Border Router
Area Border Routers (ABR) connect networks together. These routers have multiple interfaces and participate in multiple areas. There must be at least one area border router in each area connecting that area to a backbone. An ABR maintains a separate link-state database per area that it is attached to.
Designated Router
Designated Routers (DR) are used by OSPF to reduce adjacencies. Other routers establish adjacencies and synchronize databases only with the designated router and backup designated router. These routers perform two key functions for the OSPF routing protocol:
• The designated router creates a network links advertisement which lists the set of routers, including the designated router, attached to the network.
• The designated router is adjacent to all routers on the network and plays a central role in the synchronization of link-state databases across adjacencies.
One DR is elected for each network and is elected by using the Hello Protocol.
If one or more routers have declared to be the DR in their Hello packets, the one with the highest
Router Priority becomes the DR. If more than one router has identical router priority, then the router with the highest router ID becomes DR.
Backup Designated Router
Backup Designated Routers (BDR) are used for each multi-access network. The BDR is adjacent to all routers on the network and becomes the Designated Router if the existing Designated Router fails. The BDR does not generate network link advertisements and is also elected by the Hello
Protocol.
The Backup Designated Router is chosen from those routers who have not declared themselves to be the Designated Router. If a one or more routers have declared itself to be the BDR in their Hello packets, the one with the highest Router Priority becomes the BDR. If no routers have declared themselves to be BDR, then the router with the highest router ID becomes BDR.
Detailed information on the OSPF protocol is documented in RFC 2178.

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 a 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).
HSIM-W6 Installation Guide 2-15
Chapter 2: About the HSIM-W6
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.
HSIM-W6 Bridging and Routing — The HSIM-W6 can operate as a bridge, a router, or both.
The HSIM-W6 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 HSIM-W6 uses the protocol address information of the packet to route the packet to the correct destination, and if the protocol is not supported, the device uses the MAC address information to bridge the packet).
Operation of the HSIM-W6 is influenced by routing and bridging controls and filters set during
HSIM-W6 configuration. General IP routing, and routing or bridging from specific remote routers are controls set during the configuration process.
IEEE 802.1d Bridging — The HSIM-W6 supports the IEEE 802.1d standard for LAN to LAN bridging. This bridging algorithm learns the low-level MAC addresses of each LAN constituent and uses this information to decide whether to transmit the packet to another LAN via a WAN connection, or keep it local. Part of the bridging standard used, called Spanning Tree Protocol, supports multiple, redundant paths for LAN to LAN bridging, yet prevents data loops and duplication. This adds fault tolerance to a system of LANs, since, if one WAN data path fails, another may be substituted automatically.
IP Routing — IP routing support provides the ability to process 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 an IP network. The HSIM-W6 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 the
Routing Information Protocol (RIP) that allows the exchange of routing information on a Novell
NetWare network.

Bridging and Routing Protocol Filtering
Filtering is used to allow efficient usage of network resources and provide security for a network and hosts.
IP Internet Firewall — The HSIM-W6 supports IP Internet Firewall filtering to prevent unauthorized access to a 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 the Transmission Control
Protocol (TCP) and User Datagram Protocol (UDP). 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 HSIM-W6 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 HSIM-W6. 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 HSIM-W6 supports the following Bridge Filters:
• dot1d.Static Filters (IETF RFC1493)
• Ethernet Special Filtering Database (from the ctbridge-mib)
System Passwords
System passwords allow the user to control access to the HSIM-W6 by establishing three passwords. Each password provides varying levels of access to the HSIM-W6. The default password for each access level is preset to public.
The following definitions explain each of the three levels of access: read-only — passwords.
This access level allows reading of device parameters not including system

• Use QuickSET or Local Management to verify that one of the WPIM-HDSLs is involved in the connection is set to Master (Local) Timing and that the other one is set to Slave (Loop) Timing.
• Verify the use of proper cabling for the HDSL connections. Category 3 or Category 5
Unshielded Twisted Pair copper wiring is required. One pair (2 wires) for Fractional T1, two pair (4 wires) for Full T1. The presence of bridged taps and multiple wire segments connected together to form the loop may reduce the maximum distance usable between the Remote and
Local devices. Wire gauge has an impact on the distance which can be supported as well. The maximum distance is 12,000 feet using 24 American Wire Gauge (AWG) wiring.
• Verify the gauge and condition of the wire. A trained line technician may be necessary to determine this.
• Verify that the distance between the Remote and Local units is less than 12,000 Feet.

Investigating Software Configuration Problems
Investigating Software Configuration Problems
Software problems usually occur when your software configuration contains incomplete or incorrect information.
Connection to Device Fails During Software Configuration
• For a LAN connection, verify that the IP address matches the IP address previously stored into the configuration of the router. You must have previously (through QuickSET) set the Ethernet
LAN IP address and Subnet Mask, enabled IP routing, saved the Ethernet configuration changes and rebooted the router for the new IP address to take effect.
• Check that your LAN cable is wired correctly and each end securely plugged in.
• Make sure that an IP route exists between your local PC and the HSIM-W6. The PC and
HSIM-W6 must be on the same IP subnetwork or the HSIM-W6 must be reachable through a router on your LAN.
• Check Network TCP/IP properties under Windows 95 or Windows NT, as described in the
Read Me First! document.
User Cannot Communicate with Remote Network Station
If Bridging,
• Check that the Bridging Default Destination is set.
• Check that bridging to/from the remote router is set on.
• Be sure to reboot if you have made any bridging destination or control changes.
If TCP/IP Routing,
• Check that TCP/IP Routing is set on and is enabled at the remote end.
• Check that the IP address of the LAN beyond the remote router is correct, as well as the associated Subnet Mask.
• If the remote router WAN IP address and Subnet Mask are required, check that they have been specified correctly.
• Check that, if required, the source and remote WAN IP addresses are on the subnetwork.
• Check that you have seeded the routing table, if RIP is not allowed to flow on the WAN link.
• Be sure to reboot if you have made any IP address, control or protocol option changes.

Chapter 4: Troubleshooting
Troubleshooting the Frame Relay Connection
There are three troubleshooting tools available. The first has always been available and is LM. The second is the FR Error MIB Table, and reflects LMI or DLCI data errors. The third is new and is available as the Mib Nav command: “fr”.
Communication with the FR switch is done through one of two methods:
Asynchronous Status Messages — At any time the Fr Switch can send an unsolicited (no polling from us) message to us. Each message contains information on one DLCI and one only. It has the DLCI number and the DLCI state. We don’t respond to this message, but we do adjust what we know about DLCIs based on this information.
Synchronous Polling Messages — The t391 timer for the ANSI/ITU Frame Relay forms the basis for polling between the FR switch and the FR DTE (us). We transmit a STATUS ENQUIRY every t391 seconds (10 by default) to the FR switch. We expect a STATUS RESPONSE, which contains information on the DLCIs the switch has assigned to us. Every other t391 cycle we sent out a LINK INTEGRITY VERIFICATION ENQUIRYmessage (LIV). We expect to get a LINK
INTEGRITY VERIFICATION RESPONSE back from the Fr switch before out t391 polling cycle expires. This is a keep alive message that does no more than let us know the link between us and the FR switch is still alive.
The information provided in a FULL STATUS RESPONSE, or ASYNCHRONOUS STATUS
MESSAGE basically has two parts, the FR Switch provides a DLCI number, and whether that
DLCI is in the Active or Inactive state.
Active State — means that both ends of the connection (this DTE and the DTE at the other end of the WAN cloud) are speaking correctly to the FR DCE Switches in the WAN cloud. The Inactive state means that either the local or far end DTE is either just starting up and has not completed its initial negotiation with the FR Switch, or there is some sort of LMI error. Data (other than LMI negotiation messages) will only be transferred when in the Active state.
Invalid — the third state value is reported locally only. It is not done by polling the FR switch.
This is done if the physical connection has some sort of problem. The circuit will remain in the
Invalid state until negotiation with the FR DCE Switch completes successfully.
