The present invention relates to telecommunications service provision and, more particularly, to methods and systems for providing telephony services.
Packet-based telephony services, also referred to herein as Voice-Over Network (VoN), Voice-Over Internet Protocol (VoIP), and/or Internet Protocol Telephony (IP Telephony) services, are becoming increasingly popular due, in part, to marked improvements in reliability and sound quality of such services. Typically, to provide packet-based telephone communications at a customer premises, interface equipment, such as Integrated Access Devices (LADs), Analog Terminal Adaptors (ATAs), telephone adapters (TAs), and the like, is installed at the customer premises. The equipment is used to support a voice path through a broadband connection, such as a digital subscriber line (DSL) connection or cable television (CATV) connection, back to an Internet Service Provider (ISP). Customers/subscribers can connect their existing analog phones, for example, Plain Old Telephone Service (POTS) phones, to the interface equipment. The interface equipment may provide telephone functions, such as dial tone, battery, and power ringing.
It is envisioned that, as the popularity of packet-based telephony services increases, services providers, e.g., /local exchange carriers (LECs), will eventually migrate their subscriber base from traditional circuit-switched telephony services to packet-based telephony. In particular, it is envisioned that traditional telephone subscribers and broadband subscribers will eventually all be served by a packet-based telephony, while offering the opportunity for subscribers to obtain “bundled” services that include such telephone service with internet service, IP television (IPTV) and/or other packet-based services.
The customer premises are coupled to a Digital Subscriber Line Access Multiplexer (DSLAM) 100 that is configured to convert analog voice data received from the ASL lines of the ASL-only and DSL/ASL premises 10, 30 to digital packets, and to convert digital voice data in packets received at the DSLAM 100 to analog voice signals transmitted on the ASL lines. The DSLAM 100 also conveys digital packets to and from the DSL lines of the DSL-only and DSL/ASL premises. As shown, the DSLAM 100 is coupled to a packet network, here shown as including an Asynchronous Transfer Mode (ATM) or Ethernet network 50 and an Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) network 60. A VoN network 70 supports packet-based voice telephony for the premises 10, 20, 30. A gateway 80 couples the digital network to a public switched telephone network (PSTN) 90.
According to some embodiments of the present invention, methods of providing telecommunications services include providing government-regulated subscriber line transport using a first telecommunications infrastructure that includes analog and digital subscriber lines, and providing a non-government-regulated packet-based telephony service (e.g., VoN, VoIP or the like) for the digital subscriber lines and at least some of the analog subscriber lines using a second telecommunications infrastructure including a packet data communications network coupled to the first telecommunications infrastructure. The packet data communications network may be coupled to the analog subscriber lines and the digital subscriber lines without an intervening circuit-switched network. For example, the packet data communications network may be coupled to the analog subscriber lines at a digital subscriber line access multiplexer (DSLAM) that is configured to interface analog telephone lines to the packet data communications network.
In further embodiments, the packet data communications network includes a first packet data communications network, and a government-regulated packet-based telephony service is provided for a subset of the analog subscriber lines using a third telecommunications infrastructure including a second packet data communications network coupled to the first telecommunications infrastructure. The subset of analog subscriber lines may correspond to telephone lines that do not support digital subscriber line transport. Provision of a government-regulated Packet-based telephony service for a subset of the analog subscriber lines using a third telecommunications infrastructure may include providing a plain old telephone service (POTS) replacement service for the subset of analog subscriber lines using the third telecommunications infrastructure.
In additional embodiments of the present invention, providing a non-government-regulated packet-based telephony service for the digital subscriber lines and at least some of the analog subscriber lines may include providing the non-government-regulated packet-based telephony service for analog subscriber lines corresponding to telephone lines that do not support digital subscriber line transport. The analog subscriber lines corresponding to telephone lines that do not support digital subscriber line transport may be transitioned from an analog POTS service to the non-government-regulated Packet-based telephony service using a mass local number portability telephone number porting process.
Additional embodiments of the present invention provide systems for providing telecommunications services. A first telecommunications infrastructure is configured to provide government-regulated subscriber line transport to a population of subscribers, the first infrastructure including analog subscriber lines and digital subscriber lines. A second telecommunications infrastructure is configured to provide a non-government-regulated packet-based telephony service for the digital subscriber lines and at least some of the analog subscriber lines, the second telecommunications infrastructure including a packet data communications network coupled to the first telecommunications infrastructure. The packet data communications network may be coupled to the analog subscriber lines and the digital subscriber lines without an intervening circuit-switched network, e.g., at a digital subscriber line access multiplexer (DSLAM) that is configured to interface analog telephone lines to the packet data communications network. The second infrastructure may include a first packet data communications network configured to provide the non-government-regulated packet-based telephony service for the digital subscriber lines and the at least some of the analog subscriber lines and the system may further include a third telecommunications infrastructure configured to provide a government-regulated packet-based telephony service for a subset of the analog subscriber lines over a second packet data communications network coupled to the first telecommunications infrastructure.

Embodiments of the present invention relate to the provision of voice telephony services and, more particularly, to provision of packet-based telephony services. As used herein, “packet-based telephony services” may include Voice over Network (VoN) services, Voice-Over Internet Protocol (VoIP), Internet Protocol Telephony (IP Telephony) and other forms of telephony involving transmission of voice data use of packet communications over digital networks in place of traditional circuit-switched infrastructure.
In various exemplary embodiments of the present invention discussed herein, telecommunications services may be structured to use government-regulated subscriber line transport for a population of subscribers over a subscriber line infrastructure that includes analog and digital subscriber lines. A non-government-regulated voice-over-network (VoN) service may be provided for the digital subscriber lines and at least some of the analog subscriber lines over a non-government-regulated infrastructure including a packet data communications network that is coupled to the subscriber line infrastructure, for example, at a DSLAM that services the analog and digital subscriber lines. In some embodiments, for example, a network structure may include regulated physical transport (e.g., local loop) and regulated analog and digital subscriber lines, which are served by an unregulated packet network that supports bundled IP-based services that include VoN service. In other embodiments, a separate regulated packet network and VoN service may be provided for ASL-only subscribers as a VoN-based POTS replacement, while “whole house” ASL and DSL-only subscribers may be served by an unregulated packet network and VoN service.

The customer's DSL is converted from a telephone number association to a circuit identifier association (block 915). In parallel, VoN provisioning in the packet network may occur (block 940), along with generation of an order for ASL (block 945). Responsive to the DSL conversion and ASL order, a DSLAM card/port/facility may be provisioned for the new VoN service (block 920), and VoN service provisioned to the ordered ASL (block 925). A Local Service Request (LSR) is then issued for telephone number porting (block 930) and, in response to the LSR, LNP porting may be activated (block 935) and the customer disconnected from the Class 5 switch (block 950).
Technician operations may occur in parallel with the above-described operations. In particular, a technician may be dispatched responsive to the integrated order management system (block 955), leading to movement of wires for the customer premises to the provisioned DSLAM (block 960). As shown in
