摘要：
An analog MTS (Message Telephone Service) signal (TS) and an ADSL (Asymmetric Digital Subscriber Line) datastream (AD) are multiplexed to be transmitted simultaneously on a twisted pair transmission line (TL). In a first step, the analog MTS (Message Telephone Service) signal (TS) is transformed into a digital form (DS, TSC). The digital MTS (Message Telephone Service) signal (DS, TSC) in a second step is embedded in the ADSL (Asymmetric Digital Subscriber Line) datastream (AD).
At the receiver side, the digital MTS (Message Telephone Service) signal (DS, TSC) and ADSL (Asymmetric Digital Subscriber Line Service) datastream (AD) are split up again, and the digital MTS (Message Telephone Service) signal (DS, TSC) is retransformed into the analog MTS (Message Telephone Service) signal (TS).
To maintain telephone service even when the ADSL equipment fails, an alternative path enables transmission of the MTS (Message Telephone Service) signal in its analog form, independently from the ADSL equipment.
