Method and system for monitoring a telecommunications signal transmission link
First Claim
1. A method for monitoring a signal-carrying transmission link for occurrence of an event, the method comprising the steps of:
- (a) selecting a transmission link address;
(b) receiving data for the address;
(c) comparing previously stored data to the data received in step (b), wherein said comparing step is performed by an event monitor;
(d) storing an event data portion of the data received in step (b) and related address data identifying the address selected in step (a) in a storage register when a difference is detected between the previously stored data and data received in step (b); and
(e) reading the event data and related address data from the storage register, wherein said reading step is performed by a computer processor following said storing step.

Abstract
A system including an event monitor for monitoring at least one transmission link. Each event monitor receives transmission link addresses from an address sequencer and transmits related event data to a centralized storage register. The address sequencer also transmits the addresses to the storage register. The event monitor compares new event data for each address with old event data stored by the event monitor. If a difference is detected, the event monitor sends a strobe signal to the storage register, which stores the event data reflecting the difference and the related address data. The strobe signal is also sent to a signaling device, which sends an interrupt signal to cause a microprocessor to read the event and address data from the storage register. Optionally, the signaling device does not send an interrupt signal until a threshold number of strobe signals have been received.
