Abstract

A telecommunications network (80, 120, 140) for enabling resale of local services includes a distributed switching system (88) owned by an incumbent local exchange carrier which has a call control computing platform (100) coupled to a digital loop carrier (86), where the digital loop carrier (86) is coupled to a plurality of telephone service subscribers (82) of the incumbent local exchange carrier as well as telephone service subscribers (84) of a competitive local exchange carrier. A local switch (104) owned by an incumbent local exchange carrier is coupled to the digital loop carrier (86). At least one service control point (111, 122) owned by the incumbent local exchange carrier is coupled to the call control computing platform (100) and the local switch (104), where the at least one service control point (111, 122) contains service definitions and logic of services supported by the incumbent local exchange carrier as well as service definitions and logic of services supported by the competitive local exchange carrier.

a first service management system owned by the incumbent local exchange carrier being coupled to the first service control point; and

a second service management system owned by the competitive local exchange carrier being coupled to the second service control point.

7. The telecommunications network, as set forth in claim 3, further comprising:

a first service creation environment owned by the incumbent local exchange carrier being coupled to the first service management system; and

a second service creation environment owned by the competitive local exchange carrier being coupled to the second service management system.

8. The telecommunications network, as set forth in claim 3, further comprising:

a first operational support system owned by the incumbent local exchange carrier being coupled to the first service control point, call control computing platform and signal transfer point; and

a second operational support system owned by the incumbent local exchange carrier being coupled to the second service control point, call control computing platform and signal transfer point.

9. The telecommunications network, as set forth in claim 3, further comprising a second local switch owned by the competitive local exchange carrier couple to the digital loop carrier, the second local switch processing and routing calls originating from the subscribers of the competitive local exchange carrier.

10. A telecommunications network for enabling local service resale, comprising:

at least one digital loop carrier owned by an incumbent local exchange carrier being coupled to a plurality of telephone service subscribers of the incumbent local exchange carrier and telephone service subscribers of a competitive local exchange carrier;

a call control computing platform owned by the incumbent local exchange carrier being coupled to the at least one digital loop carrier, the call control computing platform being adapted to control and manage the operations of the at least one digital loop carrier;

an intelligent peripheral owned by the incumbent local exchange carrier being coupled to the call control computing platform and the at least one digital loop carrier and being adapted to provide tone and announcement and digit collection functions;

a local switch being coupled to the at least one digital loop carrier;

a first service control point being coupled to the call control computing platform and the local switch, and containing service definitions and logic of services supported by the incumbent local exchange carrier; and
