Method and apparatus for storing and retrieving performance data collected by a network interface unit
First Claim
1. A method for storing, and making available for retrieval, performance monitoring information within a network interface unit on a telecommunications circuit divided into 4 legs, each leg associated with a direction of information signal flow, the method including the steps of:
- (a) detecting at a network interface, errors on the telecommunications circuit;
(b) detecting at the network interface, alarms on the telecommunications circuit;
(c) determining during real-time operation of the telecommunications circuit, based upon signals received at the network interface, the leg of the telecommunications circuit in which originated an Event comprising a detected error or alarm; and
(d) transmitting an indication, during real-time operation of the telecommunications circuit in response to a request, the circuit leg in which it was determined the Event originated.

Abstract
A method and apparatus for storing and communicating information regarding the condition of signals which pass through the network interface between customer premises equipment and a local exchange carrier in a telecommunications system. Information stored at the network interface can be sent as a message which is encoded within the payload, within the frame bits, or within the data link. The information that is stored at the network interface is sectionalized to reduce the amount of information that need be sent and to reduce the processing required by the receiving device.

2. A network interface unit that stores, and makes available for retrieval, performance monitoring information of a telecommunications circuit divided into 4 legs, where each leg is associated with a direction of information signal flow between a first end and a second end, external to the network interface unit, wherein the network interface unit includes:
-
(a) error detecting means for determining information relating to errors on the telecommunications circuit at a network interface; (b) alarm detecting means for determining information relating to alarms on the telecommunications circuit at the network interface; (c) determination means for determining, during real-time operation of the telecommunications circuit, based upon signals received at the network interface, the leg of the telecommunications circuit in which originated an Event comprising a detected error or alarm; and (d) transmission means for transmitting an indication, during real-time operation of the telecommunications circuit in response to a request, the circuit leg in which it was determined the Event originated. - View Dependent Claims (4)

5. A method for storing within a network element, and transmitting from the network element, performance monitoring information as to where events originate within a telecommunications circuit, the telecommunications circuit having at least a first leg coupled between the network element and a first end of the circuit, such that signals are transmitted along the first leg from the first end of the circuit to the network element, a second leg coupled between the network element and a second end of the circuit, such that signals are transmitted along the second leg from the network element to the second end of the circuit, a third leg coupled between the second end of the circuit and the network element, such that signals are transmitted along the third leg from the second end of the network to the network element, and a fourth leg of the circuit coupled between the network element and the first end of the circuit, such that signals are transmitted along the fourth leg from the network element to the first end of the circuit, the method including the steps of:
-
a. determining in which leg of the circuit an event has occurred; b. associating the event with an indication as to when the event has occurred; c. storing an indication of the leg in which the event occurred and the indication as to when the event occurred; and d. in response to a request, transmitting the indication of the leg in which the event occurred and the indication as to when the event occurred. - View Dependent Claims (6, 7, 8, 9, 10, 11)
