    THE EXPRESS XL/XLT The Express XL/XLT is a standalone device that links two Local Area Net- works (LANs) using a high-speed ISDN public network or leased two-wire line. Optionally, the Express XLT has a plain old telephone service (POTS) connector that is used for voice/modem applications See Figure 1-1 for an illustration of the Express XL/XLT.

  • Page 28: Demand Routing And Bridging With The Express Xl/Xlt

    Chapter 1: Understanding ISDN and the Express XL/XLT IP Router: The Express XL/XLT can function as an IP router using the Routing Information Protocol (RIP) for advertising and learning routes among other routers. Static routes may also be entered into the routing ta- ble.

  • Page 29: Bridging

    ISDN link. Bandwidth can be controlled using the Express XL/XLT’s advanced filtering capability. When new traffic needs to be transmitted, the Express XL/XLT will run each packet through its Demand filters defined for each Connection List profile. If a packet can pass through the filter, then the numbers for that profile are dialed.

  • Page 30: Ip Routing

    Up is activated from the Dial menu when the link is down, the retained routes are removed. The Express XL/XLT can be connected to two WAN destinations at the same time. Each B-channel is dialed to a different location. Routes learned from one WAN destination are advertised to the other using RIP.

  • Page 31: Ipx Routing

    IPX Routing Like IP routing, the Express XL/XLT can connect to two different sites and ex- change 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 XL/XLT when the connection goes idle.

    NT1. For network testing, the Express XL/XLT responds to NT1 test commands from the telephone company central office (CO). The Express XL/XLT has one RJ-45 jack, labeled ISDN BRI U on the rear panel for network connection (see Figure 1-7). ISDN basic rate service divides a stan- dard telephone line into three digital channels capable of simultaneous voice and data transmission.

    ISP must preassign the customer a subnet which uses multiple IP addresses. This may result in a much higher cost to the user. The Express XL/XLT permits the user to assign any IP addresses to the unit and computers. Operations on the network can occur normally. In fact, one B- channel can connect to the ISP using NAT while the other B-channel connects to another “private”...

    - If not found, DEFAULT entry’s Rx Password is used if Rx Username is blank. When answering a call, the Express XL/XLT does not know who the PPP peer is until the authentication phase is completed. Two PPP protocols (EAP and CHAP) require the authenticator to transmit a username which the authenticatee uses to cross refer- ence the password to use.

    This is the username that is used to match the user to the Connection List pro- file. During an incoming call, the Express XL/XLT will scan all active connec- tion profiles and match the received PPP peer’s username. If the name is not found, then the DEFAULT profile is used, if and only if the DEFAULT profile has nothing in the Rx Username parameter.

    Upgrade/Transfer Method The two methods for upgrading are TFTP and XMODEM. TFTP requires a TFTP server running somewhere on the network. The Express XL/XLT starts a TFTP client function which gets the upgrade code from the TFTP server. Se- lecting XMODEM will load the upgrade code through the maintenance port using any PC terminal emulator with xmodem capability.

    XMODEM. If this happens, set a PC terminal emulation program to 9600 baud and attach to the Express XL/ XLT’s maintenance port. Press Return to display a simple terminal menu for upgrad- ing.

  • Page 129: Table 4-A

    If the line has two phone numbers, make sure the second SPID and LDN are entered correctly in SPID2 and LDN2 in the Express XL. Check with the local service provider to ensure that the line supports two data calls. The Express XL status log buffer shows what sequence of events occurred.
