The idea of this invention is to use at least two modems on the network management system side. At least one of these modems is used only for connections initialized by the network management system. At least one of the modem is used only for connections initialized by any or a group of network elements controlled by the network management system. The number of modems used for connections initiated by the management system may be more than one, thus enabling the network management system to initiate simultaneous connections to more than one network element. Likewise, more than one modem can be assigned for connections initiated by the network elements. |
