How to load ring source on PROM
1. Requirement :
27c040 PROM,
8 Ring Soureces (wave format) which you wish to install
ROM writer
2. Precedure
2-1 Ring data modification to PCM wave format ( A-law, 8 kHz, 8bit )
2-1-1 Start ‘ Sound Recorder ‘ in window start menu
2-1-2 Load Ring Source File
2-1-3 Click ‘Modification’ button on ‘Register Information’ in ‘File’ menu
2-1-4 Select ‘CCITT A-Law’ in format and ‘8000Hz, 8bit’ in attribute menu.
2-1-5 Select ‘Save As’ and Save this modified wave file as another name .
2-1-6 Follow upper procedure for other wave files
2-2 Program ring data on PROM
2-2-1 Ring data size to be programmed on PROM is about 32 kByte each
Playing Time on D-Tel terminal is about 8 second..
( 0x0000 ~ 0x7fff)
There are 8 ring data in lower address (0 ~ 0x3ffff) and Tone data(for Digit) in upper address (0x40000 ~ 0x7ffff) on PROM
2-2-2 Set ‘start address’ to 0x0000 and and ‘end address’ to 0x7fff. Load wave
file and Program. After that, you must set ‘start address’ to 0x8000 and
‘end address’ to 0xffff .
(0x10000 ~ 0x17fff , 0x18000 ~ 0x1ffff and so on)
2-2-3 If all ring data are programmed completely, you should program tone data
in address 0x40000 ~ 0x7ffff .
(You should use Tone data in previous offered PROM)
LKD Tone PROM Configuration
0x00000 ~ 0x3FFFF 0x00000 ~ 0x07FFF Ring source 1
0x08000 ~ 0x0FFFF Ring source 2
0x10000 ~ 0x17FFF Ring source 3
0x18000 ~ 0x1FFFF Ring source 4
0x20000 ~ 0x27FFF Ring source 5
0x28000 ~ 0x2FFFF Ring source 6
0x30000 ~ 0x37FFF Ring source 7
0x38000 ~ 0x3FFFF Ring source 8
0x40000 ~ 0x7FFFF Digit(0~9, *, #) tone
