Figure 16 - Application Timing: Bellcore On-Hook Data Transmission Associated with Ringing, e.g.
Calling Number Delivery, Calling Name Delivery
Notes:
This on-hook case application is included because a CIDCW CPE must also be capable of receiving on-hook data transmission (with
ringing) from the central office.
1)PWDN and FSKen are internal signals decoded from CB0/1/2.
2)The CPE designer may choose to enable the MT88E46 only after the end of ringing to conserve power in a battery operated CPE.
CD is not activated by ringing.
3)The microcontroller in the CPE powers down the MT88E46 after CD has become inactive.
4)The microcontroller times out if CD is not activated.
5)The DR/DET output pin is the DR signal when FSK is selected.
