A customer interface device for coupling a customer site to a VDSL-based video, voice and data distribution network includes a signal splitter for separating incoming narrowband and broadband from a single twisted-pair copper wire, a narrowband port for connection to existing telephone wiring at the customer site, and a broadband port for connection to a customer set-top box via a CAT 5 wire. The interface device further includes a high pass filter connected between the splitter and the narrowband port, and a low pass filter connected between the splitter and the broadband port. The filters improve broadband signal quality while preventing feedback of EMI noise from the existing building wiring to the network.

A system and method of powering a fiber optic communication network are provided which transmits communication data between a telephone company central office and remote user device. The system includes a power source configured to provide an electrical supply voltage to a digital subscriber line access multiplexer. The power source having an AC power feed for providing power to the digital subscriber line access multiplexer and a DC power feed for providing power to the digital subscriber line access multiplexer when the AC power feed is not supplying power. Further, an electrical conducting medium configured to conduct the electrical supply voltage and the communication data from the digital subscriber line access multiplexer to the remote user device is provided. Therefore, the present invention provides a system and method for reliably powering a fiber optic communication network with AC power under normal operating conditions and DC backup power when the AC power is interrupted, thus providing lifeline telephony service while, reducing maintenance costs by having a limited number of centralized remote power sites.

An XDSL signal distribution system is provided having a regenerator unit located a predetermined distance from a central office XTU unit for extending the distribution reach of the system. The regenerator is arranged to decode the payload of transmitted XDSL signals into base digital data before repackaging and regeneration onto a twisted pair copper cable. This allows the regenerator to selectively reformat the XDSL signals into a desired protocol format suitable for either an ATM protocol layer, or direct transmission. In addition, the regenerator can retransmit the XDSL signals at a fixed or variable transmission rate to optimize data through-put or system reach.

A method and system for providing telephony services utilizes an emulated telephony channel within an allocated portion of digital subscriber line bandwidth. The digital subscriber line connects to a packet switched network, and embodiments of the present invention derive telephony services over the digital subscriber line by utilizing a portion of the available bandwidth to emulate one or more telephony channels.

A test procedure for a VDSL distribution loop utilizes loop pre-qualification based on information stored in a network database in combination with field tests that are performed to confirm minimum performance capabilities of pre-qualified loops. During qualification, a VDSL test signal is sent on the loop, and SNR and bit error ratios are measured for desired upstream and downstream transmission rates. These measurements are compared to threshold values to verify performance of the loop for VDSL use. Thus, a cost effective test process is provided which allows accurate test data collection for sensitive VDSL distribution loops without the need for any pre-provisioning of the loop, and to allow for validation of the loop configuration database.

A system and method for collecting, integrating, and distributing video, data, and telephony signals in a fiber optic communications network for transmission along a twisted copper pair to a customer location. The video, data, and telephony signals are received by a digital subscriber loop access multiplexer and are superimposed onto the twisted copper pair using a service area interface. The system and method enables a customer to receive video, data, and telephony communication data along a single twisted copper pair at relatively high data transfer rates. Additionally, since portions of the existing communication infrastructure are used the cost of implementation is reduced.
