LANE Modules
The following ATM LANE modules are available for the 5000 family of switches; the list also indicates the
cable types that can connect to each. Tables 8.1 and 8.2 show the LED lights and functions on the LANE
modules. These modules provide a connection between multiple ATM networks connecting through the ATM
switch:

The single−mode LANE module is better equipped for longer distances. It uses a laser optical source and has
a maximum distance of 10 kilometers. The multimode module uses an LED optical source and has a
maximum distance of two kilometers. Both modules have a SAR of 512, meaning that the module can
segment and reassemble up to 512 packets simultaneously.
Network Management on the LANE Module
The LANE modules in the Catalyst 5000 and 5500 series switches are configured by using the standard Cisco
command−line interface (CLI), which is similar to that of a router. This interface can be accessed through the
