The term Public Switched Telephone Network, or PSTN refers to the public communication system providing long distance, local and extended local telephone service. A group of common communications carriers make it available to the public. Those who are subscribed can make calls to anyone with access to this system no matter which carrier he or she uses.
Customer Premise Equipment is the term, which describes the devices used to connect subscribers to the PSTN through a NID, or a network interface device. The customer's equipment is only separated from the equipment of the company by that, which serves as an imaginary line, called demarcation.
