NW6005 ENHANCED TYPE II CALLER ID DECODER
Notes:
1) A= 75 - 85 ms, B= 0 -100 ms, C= 55 - 65 ms, D= 0 - 500 ms, E= 58 - 75ms, F depends on data length, G 50 ms.
2) If AC power is not available, the designer may use the line power when the CPE goes off-hook and use battery power while on-hook. The
3) If the end office fails to send the FSK signal, the CPE should disable FSKEN and unmute the handset and enable the keypad after this
4) When FSK signal is not expected, the FSKEN should be set low to disable the FSK demodulator.
5) FSKEN should be high as soon as the CPE has finished sending the acknowledgement signal ACK.
6) FSKEN should be low when CD become inactive.
7) PWDN, FSKEN and Hybrid DT-ASEN are internal signals decoded from Control Bits CB2-0.
8) When CB0 is low, both DR and DCLK pins are unused.
CPE should also be CID (on-hook) capable .
