ANCP NABAT contains the set of multipurpose terminals of various degrees of complexity plus several types of modules: communication, adaptors and secondary power supplies. All system components are developed under uniform system and design requirements. Data transfer between the components of ANCP NABAT is based on IP network layer with SIP protocol over it. All terminals are designed in desktop, wall-mounted and built-in versions with ability of harsh climate operation. Generally, terminals are equipped with built-in speech devices but there is the option of additional external speech devices connection. Some of terminal types are equipped with built-in uninterruptable power supplies (UPS) whereas the other ones are fed remotely. Communication, adaptor and power supply modules are designed in standalone form-factor with ability of putting them into stack. But if necessary all modules can be mounted into 19-inch racks.
