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:

ATM LANE Single PHY Module (UTP)—Provides a connection between the 155Mbps ATM network,
Category 5 UTP cables, and one RJ−45 connector
•
ATM LANE Single PHY Module (MMF)—Provides a connection between a 155Mbps ATM network
and one multimode SC fiber−optic connector
•
ATM LANE Single PHY Module (SMF)—Provides a connection between a 155Mbps ATM network
and one single−mode, SC fiber−optic connector
•
ATM LANE Dual PHY Module (UTP)—Provides two connections between the ATM network,
Category 5 UTP cables, and two RJ−45 connectors
•
ATM LANE Dual PHY Module (MMF)—Provides two connections between an ATM network,
multimode fiber−optic cable, and two multimode, SC fiber−optic connectors
•
ATM LANE Dual PHY Module (SMF)—Provides two connections between an ATM network, a
single−mode fiber−optic cable, and two single−mode, SC fiber−optic connectors
•
ATM Dual PHY OC−12 Module (MMF)—Provides two connections between the OC−12 (622Mbps)
ATM network, a single−mode fiber−optic cable, and two single−mode, SC fiber−optic connectors
•
ATM Dual PHY DS3 Module—Provides two interfaces for two DS3 (45Mbps) connections between
an ATM network, 75−ohm RG−59 coaxial cable, and two Bayonet−Neill−Concelman (BNC)
twist−lock connectors
•
ATM Dual PHY OC−3 Module (MMF)—Provides two direct connections between an OC−3
(155Mbps) ATM network, multimode fiber−optic cable, and two multimode, SC fiber−optic
connectors
•
ATM Dual PHY OC−3 Module (SMF)—Provides two direct connections between an OC−3
(155Mbps) ATM network, a single−mode fiber−optic cable, and two single−mode, SC fiber−optic
connectors

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
