The System operates in two modes:
а) BTC mode – applied in case of power mains failure; the System users are pow-
ered from inductor (manual electric generator), which is integrated into telephones (сom-
mutator telephones). The System operation in this mode is not limited by time, all func-
tions (see 1.2) will be available; external signaling units (if any) may operate or be dis-
connected
depending on power availability;
б) PA mode – applied in case of available power mains; the System users are
powered from external power source. Telephones and сommutator telephones in this
mode operate as regular PA
devices; a call is initiated by corresponding button; telephone
communication in the user network is carried out from external PSU and do not require
manual generator.
