History

Specifies the technical requirements for equipment known generically as common air interface second generation cordless telephones or CA1 CT2. Specifies the essential requirements for: generation and interpretation of digital control signalling; generation and interpretation of digital speech; the means by which the specified data structures are modulated onto one of a number of specified radio frequency carriers; and the means by which the two ends of a cordless link become and remains synchronised. Does not cover the means by which the fixed part of the cordless telephone system is connected to the PSTN.
