Abstract

In a pager receiver operable in response to an incoming signal including a specific call number signal preassigned to the pager receiver, a directory number signal of a calling subscriber follows the specific call number signal. The directory number signal is detected by a directory number detector (17) after detection of the specific call number signal and is converted into a corresponding dial tone signal by a dial tone generator (21). The dial tone signal is automatically sent through a telephone set to the calling subscriber in response to closure of a switch (19). Thus, the pager receiver may be of a tone-only type and can call back unspecific persons even when the directory number signal is not displayed on a display unit. A particular symbol may be included in the directory number signal so as to distinguish the directory number signal from a usual message signal.
