Description
The CPC1465 is a DC termination IC used in
Single-pair High-speed Digital Subscriber Line
(SHDSL) and Integrated Services Digital Network
subscriber line (ISDN) equipment. It provides a
polarity insensitive DSL loop sealing current DC
termination with a recognizable device signature for
MLT systems. The CPC1465 passes low frequency
ISDN network signalling information via an
inexpensive optocoupler to the NT1âs internal control
logic.
