EXPRESS L1.5

H D S L C A M P U S C O N N E C T I V I T Y

The ADTRAN Express L1.5 is an HDSL bridge/router that connects LAN segments or provides remote access to a computer or network over two twisted pairs of copper. The ADTRAN Express L1.5 is designed to work back-to-back as a cost-effective LAN extension device.

The Express L1.5 provides a cost-effective campus connectivity solution. When used in a leased copper setting, the Express L1.5 delivers 1.536 Mbps bi-directionally over two twisted pairs of copper. The Express L1.5 is also capable of transmitting at sub-rates ranging from 128 kbps to 1.536 Mbps. This solution can be used to extend a LAN or provide remote access to a single user or LAN segment. When used in the sub-rate mode, the Express L1.5 can be used with a single pair of twisted copper.

Six levels of security in the Express L1.5 provide a wide selection of secu- rity options. Network Address Translation (NAT) allows a single IP address to be downloaded through Dynamic Host Configuration Protocol (DHCP) to the Express L1.5. Up to ten users can have a private IP network address downloaded from the L1.5.

The Express L1.5 can route IP and IPX packets and bridge all other pro- tocols. Routing and bridging can be performed independently or concur- rently. The Express L1.5 can operate in the Frame Relay mode providing up to ten PVCs or in a PPP mode over the LAN.

Five LEDs provide constant feedback about the L1.5’s operation. A unique slide switch on the rear panel eliminates the need for separate cables when connecting to a HUB or NIC card. Extensive logs are provided to monitor the operation of the Express L1.5.

Telnet, SNMP, and a serial EIA-232 port provide multiple methods of configuration and management.
