Abstract

A system and method for an interruption free copper cable interception and re-routing from an existing service to a new service avoiding transmission effects during the changeover is provided. The system uses a tap line and one or more termination modules to disconnect the existing service before new service is added. Test access is also provided through use of the termination module. Non-active pairs of wires are eliminated during re-routing from an existing service to a new service. Further systems and methods are provided for removing the termination module.

Claims

1. A method of providing telecommunications service comprising:

providing a signal service pathway from a first service source to a subscriber location, wherein the signal service pathway includes a first copper signal pathway including at least one pair of twisted copper wires;

accessing at least one of the pairs of wires, and adding a conductive tap line to each wire;

terminating the conductive tap lines at a termination module with a normally closed configuration, wherein the normally closed configuration includes a normally closed contact set, wherein a disconnection plug holds open the normally closed contact set;

terminating a second copper signal pathway including at least one pair of twisted copper wires at the termination module;

cutting or otherwise disrupting the signal service pathway at a location between the first service source and the conductive tap line;

after the signal service pathway is cut, removing the disconnection plug, wherein the second copper signal pathway is connected to the first signal service pathway and to the subscriber location.

2. A system of providing telecommunications service comprising:

a signal service pathway from a first service source to a subscriber location, wherein the signal service pathway includes a first copper signal pathway including at least one pair of twisted copper wires;

a conductive tap line to each wire;

the conductive tap lines terminated at a termination module with a normally closed configuration, wherein the normally closed configuration includes a normally closed contact set, wherein a disconnection plug holds open the normally closed contact set;

a second copper signal pathway including at least one pair of twisted copper wires terminated at the termination module;

wherein the second copper signal pathway is connectable to the first signal service pathway and to the subscriber location through the termination module after the signal service pathway is cut and after the disconnection plug is removed.

4. The system of claim 2, wherein the cables are 4 pair, twisted wire pair cables.

5. The system of claim 2, wherein the termination module is a Krone style multiple contact pair block.

3. (canceled)

6. A method of providing telecommunications service comprising:

providing a signal service pathway from a first service source to a subscriber location, wherein the signal service pathway includes a first copper signal pathway including at least one pair of twisted copper wires;

accessing at least one of the pairs of wires, and adding two conductive tap lines to each wire;

terminating the conductive tap lines at a termination module with a normally closed configuration, wherein the normally closed configuration includes a normally closed contact set;

after locating selected pairs of wires, terminating a second copper signal pathway including at least one pair of twisted copper wires at the termination module;

cutting or otherwise disrupting the signal service pathway at a location between the first service source and the conductive tap line;

wherein the second copper signal pathway is connected to the first signal service pathway and to the subscriber location, wherein locating selected pairs of wires includes;

I. Testing pair 1 at the block or module 46;

Add a wire (Ia) with two half taps 122 in parallel to wire 1a. This parallel wire is going through the IDC connector la at port 1A of the block.

Add a wire (Ib) with two half taps 122 in parallel to wire 1b. This parallel wire is going through the IDC connector 1b at port 1B of the block.

Test whether pair 1 is active by measuring between the contacts Ia′ and

Ib′

on the block. This is done by inserting a test plug in the disconnect slot 64 of the block.

A. If active, remove the original wires 1a and 1b between the half taps 122.

B. If not active, see below II.B.

II. Testing pair 2 at the block;

Add a wire (IIa) with two half taps 122 in parallel to wire 2a. This parallel wire is going through the IDC connector IIa′

at port 2A of the block.

Add a wire (IIb) with two half taps 122 in parallel to wire 2b. This parallel wire is going through the IDC connector IIb′

at port 2B of the block.

Test whether pair 2 is active by measuring between the contacts IIa′ and

IIb′

on the block. This is done by inserting a test plug in the disconnect slot 64 of the block.

A. If active, remove the original wires 2a and 2b between the half taps.

B. If not active, cut wires 2a, 2b, IIa and IIb at D, E, F, G. Optionally add clear caps 122′

at D &

G.

III. Test pair 3 at the block, under assumption that pair 2 was not active;

Add a wire (IIa) with two half taps 122 in parallel to wire 3a. This parallel wire is going through the IDC connector IIa′

of the block.

Add a wire (IIb) with two half taps 122 in parallel to wire 3b. This parallel wire is going through the IDC connector IIb′

of the block.

Test whether pair 3 is active by measuring between the contacts IIa′ and

IIb′

on the block. This is done by inserting a test plug in the disconnect slot 64 of the block.

A. If active, remove the original wires 3a and 3b between the half taps.

B. If not active, see II.B

7. The method of claim 6, wherein when all active pairs are connected to the block or blocks, first insert insulating plugs in all the disconnect slots of the blocks.

8. The method of claim 6, connecting the cable with the pairs that carry the new service to the other side of the blocks.

9. The method of claim 6, testing the new service at the block, by inserting a test plug in the disconnect slot and connecting a tester to the pair that carries the new service, wherein if the new service on block position I is ok, cut the wires Ia and Ib at the exchange side of the block. Then remove the test plug or insulating plug, and repeat for each position on the blocks.

10. The method of claim 6, wherein when all active pairs are connected to the new service, the cable going back to the exchange is removed.

11. The method of claim 10, wherein the blocks remain in place.

12. The method of claim 10, wherein the blocks are removed and a direct connection with a connector 122″

is made between the pairs carrying the new service and the active pairs in the cable going to the customers.

13. The method of claim 10, wherein a direct connection is made between the pairs carrying the new service and the active pairs in the cable going to the customers before removing the blocks using new wires and new half taps.
