  • Page 8: System Overview

    System Overview System Operation NX-308 system is a stored-program-controlled electronic key/hybrid telephone system ready to use as soon as it is turned on. A powerful 8031 microprocessor operating at 11.059 MHz digitally controls all speech paths and system functions. The operating program with default memory is stored in non- volatile ROM, 27512.
  • Page 9 Two types of telephone sets can be connected to the NX-308 system: proprietary electronic keysets and conventional single line telephone sets. The NX-308 24 Button Display keyset has the following standard features plus a large, easy to read, one-line, 16-character liquid crystal display.

  • Page 18 Connection Table The NX-308 system is equipped with a standard Amphenol connector, and its connections are shown in the following table. All the necessary Station connections may be accomplished through this connector. The PSTN lines are connected to a customer-supplied LJU via the line cords supplied with the system.

  • Page 19: Connecting Keysets

    Connecting Keysets Four wires (two pair) twisted cable with a double-sided modular plug and a terminal block are recommended for a keyset connection to the KSU. One end of the terminal block is connected to the MDF via a 50-pin cable, and the other end of the terminal block is connected to a keyset via a double- sided modular plug line (two pair).

    Power Failure Transfer NX-308 system transfers two C.O. lines to the related single line telephones automatically during AC power failure. The first trunk line and the second trunk line are transferred to the 7th station and 8th station respectively only when the stations are assigned to single line telephones.

  • Page 28: User (Customer)

    This section describes technician- and user-level programming. Station programming is described in the NX-308 Keyset User Guide. Features operate when the system is turned on because they are factory programmed with default data. You may use the features as factory programmed (default) or change them.
