About the ATMSpeed/155 Modules
An ATMSpeed/155 module inserts into one slot of a Centillion 100 chassis
providing ATM ports and, optionally, an integrated master control processor
(MCP). The ATMSpeed/155 module comes in the following configurations:
• An ATMSpeed/155S switch module with two single-mode (SMF) ports
• An ATMSpeed/155 switch module with two multimode (MMF) ports
• An ATMSpeed/155 switch module with four MMF ports
• An ATMSpeed/155 MCP switch module with four MMF ports, a serial port,
and a 10BASE-T port
• An ATMSpeed/155 MDA switch module with two MDA slots and three
flavors of two port MDAs: MMF, SMF, and UTP
• An ATMSpeed/155 MDA MCP switch module with two MDA slots and three
flavors of two port MDAs: MMF, SMF, and UTP; a serial port, and a
10BASE-T port
These modules offer identical functional features for ATM connectivity; the only
difference is the type of connectors on the front panel. In this guide, the switch
modules for the Centillion 100 chassis are referred to collectively as the
ATMSpeed switch modules. Each model is referred to specifically when features
and functions are unique to that particular model.
The ATMSpeed/155 switch module is an assembly that consists of a printed
circuit board with a metal module faceplate. The module includes inserter/
extractor levers and captive retaining screws on each side of the module front
panel. The module occupies a single slot in the Centillion 100 chassis.
