Mobile Remote Extensions

A mobile remote extension can be any type of telephone, provided that it is a mobile telephone used in the PLMN or a terminal used in the PSTN network. Mobile remote extension enables you to define additional public terminals that can alternate as answering position by dialing a procedure. This service is called Multiplicity. A CSTA request can also change the answering position. These additional public terminals might have a DTMF key pad. To fully utilize the feature offered by the MX-ONE Service Node, these terminals should be able to convey digits, the asterisk or star sign (*), and the hash sign (#).

A mobile extension user who calls a predefined number in the PBX by dialing either manually, using the phone book, or the calling card service; and after executing the validation, or by entering a valid PIN code that receives a dial tone (R1, R3) from the PBX; no dial tone is received when dialing R3 number.

To simplify the call procedure for a user of a mobile extension, the PLMN network operator should offer prefixing of a dialed number and a direct access to the PBX. This means that the user only dials an internal PBX number to reach the desired person, and the predefined number is added by the PLMN exchange.
