PROGRAMMING ITEMS

NOTE: SPID (Service Profile Indication Number: G4 and I-G3) menu items are displayed only in the USA models (default). SPID is used when the machine is connected under the US National ISDN network.

If SPID is not used, or if the machine is not connected under the US National ISDN network, please turn off with user parameter switch 06 bit 6. This time, subscriber number - 2 program menus (G4 and I-G3) are displayed instead.

1.2.3 REMARKS AT INSTALLATION

Programming the Subscriber Numbers

When programming the subscriber numbers, input a “-” (pause) after the area code. When the machine receives a call, it compares the digits after the last “-”

(pause) with the called number attached to the SETUP signal. The machine responds to the call only when the numbers match.

For example:

If the subscriber number is programmed as, 123-456789,

the machine responds to the call only if the last 6 digits of the called number are

456789.

If the subscriber number is programmed as, 123-456-789,

the machine responds to the call only if the last 3 digits of the called number are 789.

NOTE: Even if more than one “-” are programmed, the machine compares the digits after the last “-.”

•HDLC control

•Channel select for B channel interface control

CODEC

•A/D, D/A converter for ISDN G3 communication

LAPD Controller

•ISDN layer 1 and LAPD control

ROM

•512 kB (4 Mbit) Flash ROM for system software storage

DRAM

•2MB (16 Mbit) DRAM used

The Flash ROM program can be updated using a flash memory card and the flash memory copy tool.
