Figure 19 - Input and Output Timing for Bellcore On-hook Data Transmission Associated with
Ringing, e.g., CID
Notes:
This on-hook case application is included because a CIDCW (off-hook) CPE should also be capable of receiving on-hook data
transmission (with ringing) from the end office. TR-NWT-000575 specifies that CIDCW will be offered only to lines which subscribe to
CID.
1) The CPE designer may choose to enable the MT88E43 only after the end of ringing to conserve power in a battery operated CPE. CD is not
activated by ringing.
2) The CPE designer may choose to set FSKen always high while the CPE is on-hook. Setting FSKen low prevents the FSK
demodulator from reacting to other in-band signals such as speech, CAS or DTMF tones.
3) The microcontroller in the CPE powers down the MT88E43 after CD has become inactive.
4) The microcontroller times out if CD is not activated.
