Logical access server comprising access cards which enable service providers to supervise communication operators equipment

The invention concerns three kinds of telecommunication equipment: access cards, logical access servers consisting of said access cards, and the network management system (NMS) for supervising the logical access servers. The first item of telecommunication equipment according to the present invention, the access card, is similar to a PCU card. It also includes RAM memory and at least one processor. The access card is equipped with 1) a fixed Internet address, 2) an access agent, 3) at least one management information base (MIB), and optionally 4) a supervisory agent The MIB is a virtual information base, which is used to specify data pieces in data requests. An Internet service provider's application communicates with the access agent and requests the data stored in the access card by means of the MIB. The supervisory agent controls logins to the access card and the use of the access card. The second item of telecommunication equipment according to the present invention is the logical access server. Each Internet service provider (ISP) has its own logical access server, which consists of access cards. These access cards may belong to one or more telecommunication servers of an operator. The third item of telecommunication equipment according to the present invention is an NMS for supervising the logical access servers. The NMS enables: the naming of logical access servers, the addition and removal of access cards to logical access servers, and the supervision of logical access servers.
