Chapter 1. Understanding ISDN and the Express 4110/4120 Figure 1-10. SOHO to Corporate LAN (4120) The Express 4110/4120 provides the following basic functions: 1. 2. 3. 61200176L3-1 LAN Bridge: Bridging provides a point-to-point connection between two LANs. The bridge learning function scans the source and destination media access control (MAC) addresses of all packets on its local LAN and determines which packets should be transmitted over the ISDN link.
Chapter 1. Understanding ISDN and the Express 4110/4120 4. 5. Network Address Translation (NAT): Single networks can connect to the Internet with this function. The Express 4110/4120 translates outgoing IP packets over the ISDN to the IP router at the Internet Service Provider. Popular Internet applications are supported. POTS: The POTS interfaces can be used for interfacing to dual tone multi-frequency (DTMF) analog devices such as telephones, modems, fax machines, etc.
Chapter 1. Understanding ISDN and the Express 4110/4120 Bridging In Bridge Mode, the Express 4110/4120 can communicate with two remote networks at a time. The destination is dialed by setting up a Connection List profile and choosing Dial on the Dial menu. See “Configuration/Connection List” on page 3-36 for instructions on setting up a Connection List profile.
Chapter 1. Understanding ISDN and the Express 4110/4120 IP Routing The Express 4110/4120 operates as a dial-up IP router when the Configuration/IP/IP Router/Mode option is configured to On. The Express 4110/ 4120 uses an IP unnumbered WAN interface; the IP address and mask assigned to the unit’s LAN interface apply to all routing and IP operations for the unit. If a default gateway is specified on the network of the Ethernet interface, the unit attempts to reach the gateway through that interface.
Chapter 1. Understanding ISDN and the Express 4110/4120 IPX Routing Like IP routing, the Express 4110/4120 can connect to two different sites and exchange IPX packets. Network routes and services are learned and advertised using Novell’s RIP and SAP. Routes and services learned from a separate site can be retained in the Express 4110/4120 when the connection goes idle.
Chapter 1. Understanding ISDN and the Express 4110/4120 Network Address Translation Mode NAT is a special mode of operation in which the Express 4110/4120 obtains a dynamically assigned IP address from the peer router (typically an Internet Service Provider). This allows a network of computers to benefit from Ethernet to ISDN speeds while still appearing to the Internet Service Provider (or central site router) as a single IP address, which is typical of PC based serial dial-up solutions.

Chapter 3. Terminal Menu Operation and Structure IPX/RIP Timer Write security: 3; Read security: 5 This value specifies how often the Express 4110/4120 sends out IPX RIP packets on the network segment attached to the Ethernet port. The RIP packets sent contain routing information about the networks for which this Express 4110/4120 is responsible. The default value is 60 seconds.
Chapter 3. Terminal Menu Operation and Structure Configuration/Bridge The Bridge menu is used to set up the bridge parameters for the Express 4110/4120. The bridging function runs at the Media Access Control (MAC) level which allows any protocol packets that run over Ethernet to be forwarded. Bridging can run concurrently with the IP and IPX routing. However, certain rules apply for when packets are bridged across a WAN connection.
Chapter 3. Terminal Menu Operation and Structure Bridge/WAN IP Bridge When IP routing is active, the Express 4110/4120 will allow another WAN device to bridge IP packets to it using PPP BCP. Normally, two IP routers would negotiate PPP IPCP to exchange IP packets. However, if a device can only support PPP BCP, IP packets are encapsulated by the device as bridge packets. The Express 4110/4120 can treat the WAN IP Bridge as a virtual Ethernet port connected only to a WAN device which has negotiated PPP BCP.
Chapter 3. Terminal Menu Operation and Structure device which has negotiated PPP BCP. This menu allows the IPX parameters for this virtual Ethernet to be setup. WAN IPX Bridge/Network Write security: 2; Read security: 5 This is the network address of the virtual Ethernet port. See “IPX/Network” on page 3-22 for an explanation of the IPX network number.

IPX/Type 20 Packets Write security: 3; Read security: 5 In order for certain protocol implementations, like NetBIOS, to function in the NetWare environment, routes must allow a broadcast packet to be propagated throughout the IPX networks. The Type 20 IPX packet is used specifically for this purpose.
Chapter 3. Terminal Menu Operation and Structure Connection List/Probe The Probe feature on the Express 4110/4120 is mainly used for allowing a network to have multiple virtual network connections to many destinations using the single ISDN link. The Express 4110/4120 can periodically obtain routing information from various locations and retain this in the routing tables, thereby permitting the LAN connection to be aware of the networks at this location. Probe helps keep route tables updated.
Chapter 3. Terminal Menu Operation and Structure Connection List/PPP The Express 4110/4120 supports the IETF standards for the Point-toPoint Protocol. The PPP state machine running in the Express 4110/4120 can be fine-tuned to support many applications that can be employed. The configurable items under this menu can be changed from their default values for special cases. PPP/Multilink Multilink PPP allows the two B-channels to be used together for increased bandwidth.
Chapter 3. Terminal Menu Operation and Structure Certain rules for bandwidth-on-demand apply, depending on whether BACP is negotiated. If BACP is not negotiated, the originator of the call will perform the dynamic bandwidth adjustments on its own. If BACP is negotiated, the decisions are made on either side but the call is always from the originator. PPP/Compression Write security: 3; Read security: 5 The Express 4110/4120 uses LZS® technology from hi/fnTM (formerly known as STAC) for data compression.
Chapter 3. Terminal Menu Operation and Structure PPP/Max Failure Write security: 3; Read security: 5 Due to the nature of PPP, configuration options may not be agreed upon between two PPP peers. This value is the number of configuration-naks that should occur before an option is configuration-rejected. This allows a connection to succeed that might otherwise fail. The possible values are 5 (def), 10, 15 and 20.
Chapter 3. Terminal Menu Operation and Structure Audio Audio directs the call control software to request a 3.1 kHz audio circuit as the bearer capability for the outgoing calls. The audio option is used with an ISDN line configured for voice service. In some areas, audio service costs less than data services. An audio call type does guarantee a digital end-to-end digital connection. 56K 56K directs the call control software to request a 64 kbps data circuit that is rate-adapted to 56 kbps.
Chapter 3. Terminal Menu Operation and Structure Dial Out/Attempts Write security: 3; Read security: 5 This value is the number of attempts the Express 4110/4120 will make before giving up on the connection. This is effective for manual dialing or dynamic bandwidth calls only. The range is from 1 (def) to 255. Dial Out/Initial Channels Write security: 3; Read security: 5 This is the number of B-channels to dial-up on the initial connection. Possible choices are 1 (def) and 2.
Chapter 3. Terminal Menu Operation and Structure The value ranges from 0 to 255 and is in seconds. When bandwidth is needed for another application, the idle timer is compared to this preempt time. If the idle timer is greater, the connection is preempted. If set to 255 (def), the connection is never preempted. If set to 0, the connection is disconnected immediately when another application is requested.
Chapter 3. Terminal Menu Operation and Structure Bandwidth/Samples The parameters under this menu control the rate at which the Express 4110/4120 samples the bandwidth on the B-channel(s).

SNMP Appendix C Understanding SNMP As Local Area Network (LAN) environments became standardized over the past ten years, multi-vendor equipment grew with competition. It became necessary to manage the various vendor equipment from a single control console. Thus, the Simple Network Management Protocol (SNMP) emerged as the de facto standard for managing commercial Transmission Control Protocol/Internet Protocol (TCP/IP) networks.
Appendix C. SNMP response to the network manager. The network manager collects all the data from the various network devices and presents it in a consistent form. Using SNMP Version 1, the network manager can issue three types of commands: • • • GetRequest: This command retrieves a single item or the first in a series from a network device. GetNextRequest: This command retrieves the next item in a series from a network device. SetRequest: This command writes information to a network device.
Appendix C. SNMP Communities The Express 4110/4120 permits up to eight communities to be defined. The privilege level of each community can be set. The default community is public with read-only privileges. When the IP address is all zeros, any manager of the community can access the Express 4110/4120. Traps Up to four hosts can be set to receive traps. Each host entry requires an IP address of the manager.

Glossary 10Base2 IEEE 802.3 specification, similar to Ethernet, using thin coaxial cable that runs at 10 Mbps, with a maximum distance of 185 meters per segment. Also known as Thin Ethernet or Thinwire Ethernet. 10BaseT IEEE 802.3 specification, using unshielded twisted-pair cabling and running at 10 Mbps. AEP AppleTalk Echo Protocol. Allows a node on an AppleTalk network to send a packet to another node and in return, receive an echoed copy of the packet.
Glossary central office (CO) In telephony, the phone company switching facility or center, usually a Class 5 end office, at which subscribers local loops terminate. Handles a specific geographic area, identified by the first three digits of the local telephone number. Usually the facilities of the local BOC. CSMA/CD Carrier Sense Multiple Access Collision Detect. A channel access mechanism where devices check the channel for a carrier before transmitting.
Glossary IEEE Institute of Electrical and Electronic Engineers. Professional organization that defines network standards. IEEE LAN standards are the predominant LAN standards today and include protocols similar or virtually equivalent to Ethernet and Token Ring. IEEE 802.1d An algorithm used to prevent bridging loops by creating a spanning tree. IEEE 802.2 An IEEE LAN protocol that specifies an implementation of the LLC sublayer of the data link layer.
Glossary arrangements and defines a limited set of standard, multipurpose interfaces for equipment vendors, network providers, and customers. Interworking with a public switched telephone network is retained. jabber An error condition in which a network device continually transmits garbage onto the network. In IEEE 802.3, a data packet whose length exceeds that prescribed in the standard.
Glossary netmask A 32-bit bit mask which shows how an Internet address is to be divided into network, subnet, and host parts. The netmask has ones in the bit positions in the 32-bit address which are to be used for the network and subnet parts, and zeros for the host part. The mask should contain at least the standard network portion (as determined by the address's class), and the subnet field should be contiguous with the network portion.
Glossary RS-232-C An EIA-specified physical interface with associated electrical signalling between DCE and DTE. The most commonly employed interface between computer devices and modems. RTMP Routing Table Maintenance Protocol. The AppleTalk protocol used to establish and maintain the routing information that is required by internet routers in order to route datagrams from any source socket to any destination socket in the internet.
Glossary T1 TA Also T-1. A digital transmission link with a capacity of 1.544 Mbps. T1 uses two pairs of normal twisted wires. T1 normally can handle 24 voice conversations with each conversation being digitized at 64 kbps. With more advanced digital voice encoding techniques, it can handle more voice channels. T1 is a standard for digital transmission in North America. Terminal Adaptor. A DCE that connects to the ISDN S-Interface and enables nonISDN terminal equipment to communicate over the ISDN.
Glossary 4-wire. A 4-wire circuit delivers better reception, but also costs more. All local loop circuits (those coming from a Class 5 central office to the subscriber’s phone system) are 2-wire, unless a 4-wire circuit is requested. U-interface A twisted pair subscriber loop that connects the NT1 reference point to the ISDN network, as defined in the I.411 Recommendation. This interface provides Basic Rate Access with an operating frequency of 160 kbps and an information rate of 144 kbps. Under U.S.
