Application Environment
There are three major timing differences for caller ID sequences, Bellcore, BT and CCA. Figure 9-3 is
the timing diagram for the Bellcore on-hook data transmission and Figure 9-4 is the timing diagram
for the Bellcore off-hook data transmission. Figure 9-5 is the timing diagram for the BT caller display
service on-hook data transmission and Figure 9-6 is the timing diagram for the BT caller display
service off-hook data transmission. Figure 9-7 is the timing diagram for the CCA caller display service
for on-hook data transmission.
