1.1 Brief Description

The CMX635 is an integrated Subscriber Processor designed for low chip-count ISDN voice/data

terminals and POTS terminal adaptors. Its functions facilitate operation in an ISDN feature phone

with speakerphone capability or in a POTS terminal adapter with Subscriber Pulse Metering

(SPM), DTMF encoder/decoder, Caller Line ID (CLID) and Caller ID on Call Waiting (CIDCW)

capabilities. It also implements many functions needed in an intelligent NT or NT1Plus system.

The CMX635 incorporates a 4-wire ST interface conforming to ITU-T I.430 and ETS 300 012-1

specifications. HDLC Controllers and associated FIFOs are provided for B1, B2 and D-channels,

which can be configured to automatically process the bit stuffing, flag generation/recognition,

address matching and CRC generation/checking required to support the ITU Q.921 protocol. An

IOM-2TM /GCI interface is provided to enable operation with other IOM compliant devices.

The µController interface is compatible with multiplexed and non-multiplexed address/data

busses and generic Motorola and Intel style control. The CMX635 will automatically detect which

style of interface is being used and configure itself accordingly. The device is available in a 48-

pin TQFP package and has progressive powersave modes to aid low power operation.
