Monitor the line for the data burst. It is the exact same modulation method
as the emergency alert system you hear squawking on the TV before the beep
and thunderstorm warning.
I think it comes before the first ring or right after the first ring. Some
of the original display units rectified and stored ring voltage for power so
it may need the ring first to power the display box then the data.
In any event, you can hear it if you have a butt sett with line monitor
mode.
Bell 202 is correct.

Subject: [AFMUG] ATA CallerID question
At a customer, I just hooked up a Cisco SPA122 into an Ancient Lucent
PBX system. The customer says that caller ID is not coming through, but
it used to work with his old AT&T Lines, and it appears to be hitting
the ATA Properly. Is there a setting on the ATA that needs to be set
that older systems may be looking for?
The only settings I see for Caller ID in the ATA are Caller ID Method,
currently set to 'Bellcore(N.Amer,China)' and Caller ID FSK Standard,
set to 'Bell 202' I've never had to mess with those settings before.
