An ISDN connection generally comprises one or two 64kbps channels and an overhead channel which travel over a digital copper pair. In some areas the channels may be 56kbps.
The ISDN line is provided by a local telephone company and is installed between the customer’s premise and the phone company’s central office. The signal terminating equipment at the customer’s location then places a call to CTI’s network in a similar way to a dial-up modem. The differences are that there is virtually no dialing time, and delivered Internet speeds are higher and more reliable than an analog dial-up connection. It is the customer’s responsibility to ensure that the number dialed for CTI services will not incur long distance telephone company charges. Please see our dial-up number database to see if there is a number local for your area.
After the ISDN line is connected, CTI provides the Internet bandwidth to the customer from our network backbone, which is multi-homed and interconnects with several different national and local access providers. CTI Networks’ facilitates national network interconnections between Verizon, Embarq, Cogent and Level3 with local telephone company connections between Verizon, Embarq, Level3, Frontier, and One Communications.
