Terminating Access Service

The terminating access service conveys calls handed over by Operator's System, at a POST access point for termination on any national number of POST's network. Interconnection is offered as national interconnection allowing to terminate traffic to the whole country through one access point and/or as regional interconnection allowing to terminate traffic to the 3 regional areas. Tariffs for terminating services differ from the type of Interconnection and from the type of service (national geographic numbers, freephone numbers, premium rate numbers, special numbers).

Carrier Selection (CSC) and Carrier Preselection (CPS)

Carrier Selection

The Carrier Selection Service allows end-users to choose on a call by call basis, an operator for the call handling by dialing an access code. POST provides the routing or switching service to ensure that the call is handed over to the chosen operator's network.

Carrier Preselection

Upon request of an operator, the operator's selection code will be configured for a dedicated customer line in POST's network. Three different types of CPS are provided: (i) only for national traffic, (ii) only for international traffic (iii) for all kind of traffic. All of the end-users traffic for which CPS has been ordered will be routed to the operator's network.
A subscriber who has opted for CPS can nevertheless override the CPS for specific calls by dialing POST's or another operator's Carrier Selection Code.

National Transit

The transit service is the interconnection service whereby POST routes traffic handed over from one interconnected operator's system which is transmitted to another interconnected operator's system on its telecommunications network. POST will ensure the transparent communication of all signaling information (including CLI-related), which was communicated to it in relation to the handing-over of traffic.


Number Portability

Number portability allows an end-user to retain its originally assigned telephone number when changing from one network operator (donor network; donor operator) to another (recipient network; recipient operator).
