processing before it rings the appropriate extension and sends the
Calling ID data for display.
The DBS processes Caller ID as follows:
• The CO sends a Caller ID call to the CID card/loop-start trunk.
• The CID card begins collecting the Caller ID data 30 ms after
the initial incoming ring ends.
• The loop-start trunk sends a signal to the CPC card indicating
that a call is coming in.
• When the CPC card receives the incoming call notification, it
lights the FF key(s) for the trunk red.
• The Caller ID data is transmitted to the CPC card.
• The CPC card then transmits the Caller ID call and data to the
appropriate digital extension. The FF key changes to green and
the extension rings. (The trunk FF key lights red for
approximately 4 seconds before the extension receives the call.
This is due to the time required by the Caller ID data receiving
and processing steps.)
