Batteries may be used as standby in case of a mains failure. Lead-acid batteries are often used. These are extremely heavy, and special consideration of floor strength is required in the case of large installations. , hydrogen) and thus require adequate ventilation. •They contain acid, which can spill out if the battery is damaged or knocked over. •They are capable of delivering very large current, which can cause a minor explosion and possibly start a fire if metal tools fall across the battery terminals.

Tone-Based Systems A variety of signaling systems, most of them involving the use of audio tones and pulses, have been developed for public telephone networks and have been adapted for use in PBX networks. These signaling systems use the speech circuits of a particular call to transmit information about that call. These audio-signaling systems are quite limited. First, few different signals are available so it is difficult to add new features. Second, the majority of the signals can only be sent during the callestablishment phase and not during the speech phase, making it difficult to add features that can be used during an established call.
