IMPORTANT SAFETY INSTRUCTIONS When using your telephone equipment, basic safety precautions should always be followed to reduce the risk of fire, electric shock and injury to persons. The precautions are listed below. 1. Do not use this product near water (for example, near a bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement or near a swimming pool).
Quick Startup Guide SETTING UP THE IDSL LINE The Express L128FP works over leased or “dry” copper provided by the local telephone company. See Specifications on page 4-1 for specifi- cations on maximum distance. Connect a VT 100 async terminal, or personal computer with a terminal emulator running 9600 N-8-1, to the MAINTENANCE port.
THE EXPRESS L128FP The Express L128FP is a standalone device that links two Local Area Net- works (LANs) using a high-speed DSL two-wire line. The Express L128FP has a two-wire interface and operates up to 144 kbits per second.

LANs. IP Router: The Express L128FP can function as an IP router using the Routing Information Protocol (RIP) for advertising and learn- ing routes among other routers. Static routes may also be entered into the routing table.
Chapter 1. Understanding IDSL and the Express L128FP Bridging In Bridge Mode, the Express L128FP can be used to connect two LAN segments. In this mode, all protocols are supported because they are transported across the IDSL link at the MAC layer. The Spanning Tree Algorithm can be used to guarantee a loop-free topology.
Chapter 1. Understanding IDSL and the Express L128FP Network Address Translation Mode NAT is a special mode of operation in which the Express L128FP ob- tains a dynamically assigned IP address from the peer router (typical- ly an Internet Service Provider). This allows a network of computers to appear as a single IP address.
PPP or Frame Relay connection. Rear Panel The Express L128FP has one RJ-45 jack, labeled ISDN, on the rear pan- el for network connection (Figure 1-6 on page 1-8). The OFF/ON switch block is for factory default and firmware down- loading.
Switch 2 in the up or OFF position will force the entire config- uration to be factory defaulted. The Express L128FP transfers data up to 144 kbps over a two-wire fa- cility. This type of service is a permanent connection between end- points or between the unit and the Frame Relay cloud.
Security Security on network devices is a major concern for almost anyone with a network. The Express L128FP provides many tools for securing the local network from hostile users. Connections can be authenticated using passwords. A RADIUS client can also be used.

SVCs require setup and tear down and are generally not available from Frame Relay carriers. Virtually all Frame Relay communications is done using PVCs. The Express L128FP supports PVCs only. A number called the Data Link Connection Identifier (DLCI) identifies each virtual circuit within a shared physical channel.
»» Frame Relay/Polling Frequency Write security: 3, Read security: 5 This parameter is the interval that the Express L128FP polls the Frame Relay switch using the maintenance protocol selected above. The Ex- press L128FP is required to poll the Frame Relay switch periodically to determine whether the link is active.
Write security: 3, Read security: 5 When this parameter is set to Yes (def), the mapping is used to deter- mine the protocols used. If set to No, the Express L128FP will ignore the virtual circuit with this DLCI. 3-34...
IP Map/Active Write security: 3, Read security: 5 When this is set to Yes (def), the Express L128FP will attempt to trans- port IP packets for this DLCI. A setting of No means that no IP traffic or route will be exchanged.

The virtual circuit may require an IP address to be specified at this DLCI interface. This is called a numbered interface. This address is used by the Express L128FP to respond to Inverse ARP requests. If this IP address is left as 0.0.0.0, the link is treated as unnumbered and the Express L128FP responds to the Inverse ARP with its Ethernet IP address.

This is usually referred to as being a “half-router.” However, a PPP peer which wants to assign a network address to the WAN link can do so, in which case the Express L128FP will go into “full-router” mode.
Type 20 packets should not be propagated across slower links with bandwidths of less than 1Mbps (like ISDN). However, when set to Pass (def), the Express L128FP will allow these packets to propagate over the WAN connection. This facilitates dial-on-demand applications.
PPP/VJ Compression Write security: 3; Read security: 5 When this item is set to On, the Express L128FP will perform TCP/IP header compression known as Van Jacobson compression to the PPP peer. Normally, this is not necessary over ISDN connections and can be set to Off (def) to disable it.
