What is the difference between Internet and ISDN?
ISDN internet service is basically a telephone-based network system that operates by a circuit switch, or dedicated line. It can transmit data and phone conversations digitally over normal telephone wires. This makes it both faster and of higher quality than dial-up internet service.
Which signal is sent as a response to IAM signal in SS7?

Can I add ISDN on ADSL line?
Both an ISDN and a DSL (Digital Subscriber Line) work over the same kind of network, carrying signals over copper wires. The main difference between the two is that ISDN lines must be installed as they require an adapter at both ends of the line.
What are ISDN and DSL modems?
An ISDN modem sends digital data and information from a computer to an ISDN line and receives digital data and information from an ISDN line. A DSL modem sends digital data and information from a computer to a DSL line and receives digital data and information from a DSL line.
