NX-SERIESHYBRID KEY SYSTEM GENERAL DESCRIPTION SECTION
1. SYSTEM OVERVIEW
The NX-series hybrid key system accomodates three kinds of Key Station:
NX-308, NX-820 and NX-1232.
1.1 NX-308 SYSTEM
The NX-308, with a maximum capacity of three telephone C.O. lines and eight
stations, is an analog telephone system designed for the small-sized business.
A powerful H M 6 4 1 8 0 R 1 digital microprocessor controls all speech paths and
system functions. The operating program with default memory is stored in non-
volatile ROM 27C020. Customer data is stored in RAM 62256 and is protected for
up to seven continuous days' loss of system power by a Ni-Cd battery. When AC
power is restored, the Ni-Cd battery is recharged automatically.
1.2 NX-820 SYSTEM
Designed for small to medium-sized businesses, the N X - 8 2 0 is an analog
telephone system featuring a maximum capacity of forty (40) ports, made up of
the combined total of C.O. telephone lines and stations, permitting various
configurations. Comprised of a Key Service Unit, expansion boards, electronic
keysets and conventional single line telephones, the N X - 8 2 0 offers small or
medium-sized business users flexible control of telephone communications. A
powerful HM64180R1 digital microprocessor controls all speech paths and system
functions. The operating program with default memory is stored in non-volatile
ROM 27C020. Customer data is stored in RAM 681000, and is protected for up to
seven continuous days' loss of system power by a Ni-Cd battery. When AC power
is restored, the Ni-Cd battery is recharged automatically.
1.3 NX-1232 SYSTEM
The NX-1232 is an analog telephone system designed for small to medium-sized
business. The NX-1232 system has a maximum capacity of forty eight (48) ports,
made up of the combined total of C.O. telephone lines and stations, permitting
various configurations. Comprised of a Key Service Unit, expansion boards,
electronic keysets and conventional single line telephones, the N X - 1 2 3 2 s y s t e m
offers small or medium-sized business users flexible control of telephone
communications. A powerful HM64180R1 digital microprocessor controls all
speech paths and system functions. The operating program with default memory is
stored in non-volatile ROM 27C020. Customer data is stored in RAM 681000, and
is protected for up to seven continuous days' loss of system power by a Ni-Cd
battery. When AC power is restored, the Ni-Cd battery is recharged automatically.

3. SYSTEM CONFIGURATION
3.1 NX-308 SYSTEM
The basic KSU (Key Service Unit) comes equipped to operate three telephone
lines and eight stations. Station #1 is assigned to be used with a keyset and
stations #2 through #8 are assigned as keysets or single-line telephones.
The NX-SMDR/R-MMC board is the SMDR and REMOTE MMC serial interface,
and the NX-DPH/PAGING board is the door phone and external paging interface.
These optional boards can be installed on the base board
3.2 NX-820 SYSTEM
The basic KSU (Key Service Unit) comes equipped to operate four telephone lines
and twelve stations. Stations #1 through #4 are assigned to be used with keysets and
stations #5 through #12 are assigned for single-line telephones. The NX-820 system
accomodates several kinds of expansion card. The NX-2TRK, NX-4TRK, NX-4KLI,
NX-4SLI, NX-4OPX, NX-8KLI and N X - 8 S L I cards may be installed in any of the three
expansion slots. By combining these cards, the N X - 8 2 0 system can be increased to
its maximum capacity of forty ports. Optionally, the N X - S M D R / R - M M C , N X -
DPH/PAGING, NX-MPD and NX-PRS board can be installed on the base board.
The NX-SMDR/R-MMC board is the SMDR and REMOTE MMC serial interface,
the NX-DPH/PAGING board is the door phone and external paging interface and
the NX-MPD, NX-PRS board are interface for calculating call cost.
But, maximum keyphone part is restricted to twenty four(24) ports although three
NX-8KLI cards are used.
