1.SystemOverview

The NX-828 system is an analogue telephone system designed for small to medium-sized

businesses and for meeting CE (EMC +safety) regulations as well as the related PTT

regulations. The system has amaximum capacity of forty (40) ports, being the sum of telephone

lines and stations-the combinations of which are flexible. Comprising only aKey Service Unit

(KSU), option cards, electronic keysets and conventional single line telephones, the system

offers small or medium-sized business user's the flexibility and control of telephone

communications. Apowerful HM64180R1 microprocessor digitally controls all speech paths and

system functions. The operating program with default memory is stored in non-volatile ROM 27C

020. Customer data is stored in RAM 681000 and is protected by arechargeable Ni-Cd battery

for up to seven day's continuous loss of system power.

2.SystemConfiguration

The basic KSU comes equipped to operate four (4) telephone lines and twelve (12) stations.

Stations from #1 to #4 are assigned to keysets, and stations from #5 to #12 are assigned to

single line telephones. The NX-828 system has several types of option card: the NX-4TRK, NX-

8KLI, NX-8SLI and NX-4OPX card can be installed in any slot of the three expansion slots. By

combining these cards, the system can be increased to its maximum capacity of forty (40) ports.

Optionally, the NX-SMDR/R-MMC and NX-DPH/PAGING cards can be installed on the base

board for value-added features.

The NX-SMDR/R-MMC card is the serial interface card for SMDR and Remote MMC, and the

NX-DPH/PAGING card is the door phone and external paging interface card. The NX-MPD

Hybrid IC (50Hz, 12 or 16KHz) can be installed on the base board and the NX-4TRK option card

for four (4) trunk ports up to amaximum of four per card. The chart below describes

configurations using option cards.
