Hybrid Fiber Coax (HFC)
Fiber In The Loop (FITL)
Pair Gain System
Channel Banks
Description
The CPC75282 Dual Line Card Access Switch
(LCAS), a member of Clare’s next generation Line
Card Access Switch family, is a monolithic solid state
device that provides the switching functionality of four
2-Form-C relays in a single, small, economical
package.
The CPC75282 Dual LCAS device is designed to
provide ringing and test access to the telephone loop
in Central Office, Digitally Added Main Line, Private
Branch Exchange, Digital Loop Carrier, and Hybrid
Fiber Coax/Fiber-In-The-Loop analog line card
applications. Test access switches provide access to
the telephone loop for line (drop) test or message
waiting in the PBX application.
