Abstract

A method and apparatus for monitoring telecommunication signals carried by a telecommunication network (10) including a signal transfer point device (12) for routing data, clock and control signals over a link (14) and a link monitor (16) operable for monitoring the link (14) is disclosed. The method and apparatus provides for the monitoring of the data and clock signals routed over the link (14) without tapping into the control signals routed over the link (14).

Claims

1. In a telecommunications network including a signal transfer point device for routing data, clock and control signals over a link and a link monitor operable for monitoring said link, a method of monitoring said data and clock signals routed over said link, said method comprising the steps of:

interposing a data tap between said signal transfer point device and said link; and

using said data tap to deliver said data, clock and control signals from said signal transfer point device to said link;

said using step further including the steps of tapping into said data and clock signals, delivering said tapped data and clock signals to said link monitor and separating said control signals from said data and clock signals for preventing tapping into said control signals.

2. The method as set forth in claim 1, said data tap including

an input connector operable for coupling with a corresponding connector coupled with said signal transfer point device for receiving said data, clock and control signals from said signal transfer point device;

an output connector operable for coupling with a corresponding connector coupled with said link;

means for electrically coupling said input connector with said output connector for delivering said data, clock and control signals from said input connector to said output connector and said link;

a tap connector operable for coupling with a corresponding connector coupled with said link monitor; and

means for tapping into said coupling means for tapping said data and clock signals from said input connector to said tap connector for delivery to said link monitor and for preventing tapping into said control signals.

3. The method as set forth in claim 2, further including the steps of coupling said input connector with said corresponding connector coupled with said signal transfer point device, coupling said output connector with said corresponding connector coupled with said link, and coupling said tap connector with said corresponding connector coupled with said link monitor for delivering only said data and clock signals to said link monitor and for preventing delivery of said control signals to said link monitor.

4. The method as set forth in claim 3, said link including a plurality of data, clock and control link lines for routing said data, clock and control signals, respectively.

5. The method as set forth in claim 4, said input connector including a plurality of data pins adapted for coupling with said data link lines, a plurality of clock pins adapted for coupling with said dock link lines, and a plurality of control pins adapted for coupling with said control link lines.

6. The method as set forth in claim 5, said output connector including a plurality of data pins coupled with said input connector data pins, a plurality of clock pins coupled with said input connector clock pins, and a plurality of control pins coupled with said input connector control pins.

7. The method as set forth in claim 6, said tap connector including a plurality of data pins coupled with said input connector data pins and a plurality of clock pins coupled with said input connector clock pins.

8. In a telecommunications network including a signal transfer point device for routing data, clock and control signals over a link and a link monitor operable for monitoring said link, a data tap for coupling said link monitor with said link for permitting monitoring of said link, said data tap comprising:

an input connector operable for coupling with a corresponding connector coupled with said signal transfer point device for receiving said data, clock and control signals from said signal transfer point device;

an output connector operable for coupling with a corresponding connector coupled with said link;

means for coupling said input connector with said output connector for delivering said data, clock and control signals from said input connector to said output connector and said link;

a tap connector operable for coupling with a corresponding connector coupled with said link monitor; and

means for tapping into said coupling means, said tapping means including means for tapping into said data and clock signals, means for delivering said tapped data and clock signals from said input connector to said tap connector, and means for separating said control signals from said data and clock signals for preventing tapping into said control signals.

9. The data tap as set forth in claim 8, said link including a plurality of data, clock and control link lines for transferring said data, clock and control signals, respectively.

10. The data tap as set forth in claim 9, said input connector including a plurality of data pins adapted for coupling with said data link lines, a plurality of clock pins adapted for coupling with said clock link lines, and a plurality of control pins adapted for coupling with said control link lines.

11. The data tap as set forth in claim 10, said output connector including a plurality of data pins coupled with said input connector data pins, a plurality of clock pins coupled with said input connector clock pins, and a plurality of control pins coupled with said input connector control pins.

12. The data tap as set forth in claim 11, said tap connector including a plurality of data pins coupled with said input connector data pins and a plurality of clock pins coupled with said input connector clock pins.
