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.
