On Friday, November 14, 2003, the ANRC President Decision no.1334/2002 on the procedure for granting the right to use national and international signalling point codes, entered into force following its publication in the Romanian Official Journal, Part I, no.795 of November 11, 2003. The decision establishes the conditions under which a provider of electronic communication public networks may obtain and may exercise the right to use certain national and international signalling point codes within the SS7 signaling system.
The international signalling point codes are allotted to the national authorities by the International Telecommunications Union. In their turn, the national authorities manage these codes and grant them to operators, individually. The signalling point codes within the internal networks of the operators are managed by the respective operators.
The electronic communications public networks providers have to submit a request to ANRC in order to obtain the right to use national and international signalling codes. The Authority analyses all requests and grants this right within three weeks since their registration date. The right to use these codes is granted for an unlimited period, but it may be withdrawn or suspended if the holder does not meet his obligations. Also, this right may end on the request of the holder.
The electronic communication networks establish links among the terminals connected to the networks. In order to establish, maintain and monitor these links, a signalling information transfer is needed – among terminals and the switchers they are connected to, and among the switchers within the network, and the systems of different networks, in the case of interconnection. In order to answer the new demands induced by the digital networks, the International Telecommunications Union (ITU) standardized a new signalling system, known as SS7, where messages are transmitted through dedicated circuits – which are different from the circuits used for voice transmission, for example. Within a signalling network, each switching system has associated a node, called signalling point and which can be identified through a code.
