Chapter 1: Understanding HDSL and the Express L768/L1.5

Rear Panel

The Express L768/L1.5 has one RJ-45 jack, labeled HDSL, on the rear panel for network connection (see Figure 1-6). There are two sets of switches on the back panel. The TO HUB/TO NIC switch allows the Express L768/L1.5 to connect directly to a Network Interface Card (NIC) or a HUB without the need for spe- cial cabling. The OFF/ON switch block is for factory default and firmware downloading. With switch 1 in the up or OFF position, the Express L768/L1.5 will immediately go into a download mode when power is enabled. Switch 1 must be in the down or ON position in order to boot up normally. Switch 2 in the up or OFF position will force the entire configuration to be factory default- ed.

The Express L768 transfers data up to 768 kbps over a two-wire facility. The Express L1.5 transfers data up to 1.536 Mbps over a four-wire facility. This type of service is a permanent connection between endpoints or between the unit and the Frame Relay cloud. It is sometimes referred to as a leased connec- tion, a dedicated connection, a nailed-up connection, or a private circuit. Leased connection or leased line is used in this manual to represent these types of services.

Configuration

The Express L768/L1.5 is configured using a menu-based interface. This in- terface can be accessed via the maintenance port using any asynchronous VT 100 terminal or personal computer running a terminal emulation program, or via the LAN using a Telnet client program. To use the Telnet interface, the Express L768/L1.5 must first have an IP address programmed into it via the maintenance port. The factory default is 10.0.0.1.
