ISP Information:
short for Ultra DMA
ISP Glossary:
UDMA - In Holland the ID digits are DC modulated on the analogue line, prior toapplying AC ring signal. ISDN, of course uses the D channel for signalling,and should be pretty much the same all over the world.Hope this helps some.Bhoot Nath schreef in berichtnews:telecom22.620.4@telecom-digest.org: I have a very simple question about caller-id technology: Is the implementation of caller ID technology same in different countries? In other words, will a caller-ID phone purchased in US work in India / Europe / Australia? Assume that the local exchange is caller-id-capable, and phone owner subscribes to this service. The question is about compatibility of the data sent from exchange to the phone. (E.g., TV broadcasts use different format, so the same TV does not work in different countries, even ignoring the power voltage / frequency issues) Bhoot Nath
