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:

an office-side 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; and

a subscriber area interface configured for communication with the telecommunications users;

wherein the radio interface unit and the digital interface unit are removable and are configured to provide temporary telecommunications service over a temporary radio link until permanent optical or copper plants are deployed, whereupon the radio interface unit and the digital interface unit may be removed and replaced with a fiber optic cross connect or a digital distribution point when the permanent optical or copper plants are deployed.

2. The system of claim 1 wherein the subscriber side interface comprises a subscriber-side radio interface unit for radio communication with the telecommunications users.

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

an office-side connection arranged for communication with a central office, the office-side connection including a first radio interface unit which communicates a first radio signal including a plurality of voice channels for communication between the central office and a plurality of subscribers in the service area; and

a subscriber-side connection arranged for communication with a telecommunication subscriber, the subscriber-side connection including a second radio interface unit which communicates a second radio signal including a single voice channel for communication between the central office and a single subscriber in the service area;

wherein the first radio interface unit includes one or more interface components which are removable and are configured to provide temporary telecommunications service to the central office over a temporary radio link until a permanent non-radio interface is deployed, and whereupon the one or more interface components may be removed and replaced when the permanent non-radio interface is deployed.

4. The system of claim 3 further comprising a multiplexer coupled with the first radio interface unit and the second radio interface unit and which separates the single voice channel for the single subscriber from the plurality of voice channels.

5. The system of claim 4 wherein the first radio signal comprises a DS3 radio signal and the second radio signal comprises a DS1 radio signal and wherein the multiplexer is a 3:

1 multiplexer.

6. The system of claim 5 wherein the first radio interface unit comprises a DS3 radio and a DS3 cross connect system and wherein the second radio interface unit comprises a DS1 radio.
