POTS is Plain Old Telephone Service – It is still used for MANY things and is a giant black hole that businesses are pouring billions per year into – Most credit card machines still use them, but an IP-Enabled Credit Card Terminal does a transaction in under a second versus 25-45 seconds over POTS.
A 10-Page FAX can take up to 10 minutes to send over POTS – The same scanned document sends in SECONDS over E-Mail.
It is well past time for Analog to go the way of the Mullet and Bell Bottoms!
