Abstract

A system and method for providing telecommunications service to users in a service area using a wireless link. An office-side connection system is provided for connecting a local distribution system to the central office switch. The local distribution system includes a cross-connect system and a radio for linking to a second local distribution system. The second distribution system includes subscriber connections for connecting to the user telecommunications devices. The radio may be enclosed in a hut or cabinet with the cross-connect system. The radio may also be enclosed in a hut while the cross-connect system is enclosed in a cabinet. The radio may be temporary to provide a temporary radio link until a permanent optical or copper cable can replace the radio.

Claims

1. A system for providing telecommunications service to telecommunications users in a service area, the system comprising:

a fiber optic cross-connect panel configured for communication to a central office over an optical link;

an optical/electrical converter coupled to the fiber optic cross-connect panel;

a m/n multiplexer coupled to the optical/electrical converter;

one or more DSX cross-connects coupled to the m/n multiplexer; and

a plurality of DSn radios coupled to the one or more DSX cross-connects and configured for radio communication to a local telecommunication service distribution system.

2. The system of claim 1 wherein the optical/electrical converter is configured to convert an optical OC-1 signal to an electrical signal.

3. The system of claim 2 wherein the m/n multiplexer is configured to multiplex the electrical signal between the optical/electrical converter and the one or more DSX cross-connects.

4. A system for providing telecommunications service to telecommunications users in a service area, the system comprising:

a radio interface unit;

a digital interface unit coupled to the radio interface unit;

a digital signal cross-connect coupled to the digital interface unit;

a digital loop carrier;

a subscriber area interface configured for coupling to telephone system lines to the telecommunications users; and

a narrow band protection unit coupled between the digital loop carrier and the subscriber area interface and configured to provide electrical protection to the telephone system lines.

5. The system of claim 4 further comprising a wide band protection unit coupled between the digital signal cross-connect and the digital loop carrier.

6. The system of claim 4 wherein the radio interface unit is removable from the system.

7. The system of claim 4 wherein the radio interface unit and the digital interface unit are integrated in a single component.

8. The system of claim 7 wherein the single component is removable from the system.
