    摘要: A telecommunity alarm system having a plurality of security surveillance modems that can be connected to a telecommunication network via an analog or digital subscriber terminal port, the security surveillance modems forming a group of a predetermined size. The security surveillance modems each have a first memory for storing telephone numbers of the other modems in the group, a second memory for identifying the particular modem and a programmable control unit. The modems are designed to dial automatically, in the event of an alarm, the other security surveillance modems belonging to the group and signal the alarm status.
