... NW6005 ENHANCED TYPE II CALLER ID DECODER PIN INFORMATION (CONTINUED) Name Type Pin No. Data Ready or DT-AS Detection Delayed Steering Output. This pin is active low. When FSK demodulation is enabled, this pin is the Data Ready output. In FSK interface mode 0, this pin is unused and reads ‘1’. While mode 1, this pin is normally high and goes low for half a bit time at the end of a word ...

... CB2 Function Select 0 FUNCTIONAL DESCRIPTION CALLER ID SPECS SUPPORTED The NW6005 is a type II Caller ID device with Call Waiting capability. It supports Bellcore, BT and ETSI specifications. The major differences between above specs are as follows (see Fig. 11, Fig. 12 and Fig. 13 for reference): BELLCORE AND TIA ...

... NW6005 ENHANCED TYPE II CALLER ID DECODER DT-AS DETECTION ON EITHER TIP/RING OR HYBRID RECEIVE PAIR In off-hook services, the detection of Dual Tone Alert Signal (DT-AS) will affect the quality of the call waiting service. Even though the end office has muted the far end party before and after it sends DT-AS, the near end user who is to receive the FSK information may be still talking ...

... NW6005 ENHANCED TYPE II CALLER ID DECODER DUAL TONE ALERT SIGNAL DETECTION The Dual Tone Alert Signal is used only in off-hook signalling in Bellcore system and ETSI system, but in BT system it is used in both on and off-hook signalling. The low and high tone frequencies of three different systems are as follows: BT ± ...

... NW6005 ENHANCED TYPE II CALLER ID DECODER FSK DEMODULATION The key part among the functions offered by NW6005 is FSK demodulation. This function is implemented by several stages: first, the carrier detector provides an indication of the presence of signal at the bandpass filter output; second, the device’s dual mode serial interface allows convenient extraction of the 8-bit data words in the demodulated FSK bit stream ...

... NW6005 ENHANCED TYPE II CALLER ID DECODER OTHER FUNCTIONS POWER-DOWN MODE The device provides the power-down feature to reduce the power consumption. Power-down can be activated by setting Control Bits 0-2 to ‘100’. Note that momentary transition of CB0-2 into the power-down code won’t activate power-down but will reset the device. ...
