Abstract
A two wire DDS Transport System is disclosed wherein digital signals are transported over a single channel between transmission line elements transporting digital data between a Network Service Provider and a Customer's Premises. ISDN U-Interface Transceivers having scaled operating frequencies and data buffers are provided in the transmission line elements, such as an Office Channel Unit (OCU) and a Network Interface Unit (NIU) to increase operating distance.
Claims18
A digital data service transport system for transporting digital data to and from a network provider's facility to a customer's premises, said system comprising:
- a first line element having an ISDN U-Interface Transceiver;
- a second line element having an ISDN U-Interface Transceiver;
- and
- a single wire pair operatively connecting said first line element with said second line element;
- said ISDN U-Interface Transceivers having an operational frequency modified from a standard frequency.
A two-wire digital data transport system for transporting digital data service between telecommunication network equipment, said system comprising:
- an ISDN U-Interface Transceiver for receiving data from and transmitting data to said network equipment, said ISDN U-Interface Transceiver having a means for modifying the operating frequency of the transceiver;
- and
- a data buffer for buffering data received and transmitted by said transceiver;
- said system characterized as having an increased operating distance.
A method for increasing the operating distance between two line elements in a digital data service transport system, said method comprising the steps of:
- providing said two line elements with an ISDN U-Interface Transceiver;
- modifying the frequency of said ISDN U-Interface Transceiver;
- and
- buffering data received and transmitted by said ISDN U-Interface Transceiver.
