CA 2333325

A system is dislosed for allowing the stations of a telecommunications trunk to communicate with one another, and with a control centre, using IP addresses and packets on the trunk service line. This is effected by the use of service packets or headers having short (preferably single-byte) station addresses so that the service packets can be routed by low-level routines without the need to buffer or examine each IP packet. When the service packets reach their destinations, the IP packets can be extracted and processed by IP-capable remote site controllers at each station. As a result, communication between the control centre and any station can be conducted transparently using higher level protocols such as SNMP/UDP/IP. A method of monitoring alarms at trunk stations using this communications system is also disclosed.

L'invention concerne un système permettant aux stations de circuit long de télécommunications de communiquer entre elles et avec un centre de commande, au moyen d'adresses et des paquets IP, sur la ligne de service de circuit long. L'utilisation de paquets ou d'en-têtes de service, ayant des adresses de station courtes (de préférence, à un seul octet), permet que les paquets de service soient acheminés par des routines de niveau inférieur, sans avoir besoin de séparer ou d'examiner chaque paquet. Lorsque les paquets de service atteignent leur destination, les paquets IP peuvent être extraits et traités par des contrôleurs de site à distance disposant de capacité IP, au niveau de chaque station. En conséquence, une communication entre le centre de commande et une station peut être établie de manière transparente, à l'aide de protocoles de niveau plus élevé, tels le SNMP/UDP/IP. L'invention concerne également un procédé d'alarmes de surveillance au niveau des stations de circuit long utilisant ce système de communications.
