Programming Procedures

Procedure Principles

The procedures for utilizing the features of the AS253x are

optimized out of consideration for the human factor in

order to:

meet the user’s expectations

be easy to learn and relearn

not invoke any automatic functions which the user

doesn’t expect

protect the user from committing critical errors, e.g.

dialing wrong numbers, deleting stored numbers, etc.

be consistent, simple and usable.

The following chapters describe the operating procedures

for the provided features. Pressing an invalid key or key

combination during programming will cause the device to

abort the program state. Pressing any key combination or

sequence which is not described or defined may cause the

device to enter a state or mode that does not comply with

the expectation of the user. In such cases, any undesired

state can be terminated at any time by going on-hook / off-

hook which will generate a functional reset.

Storing Numbers (not AS2534)

Up to 14 numbers, each with maximum 21 digits, can be

stored into the internal RAM.

Press [P/M] to enter program mode

Enter location (MR + digit1; or M1 to M12)

Enter number - entries (0-9, *, #, PS or LNR, R1, R2,

R3) will b written directly into the selected memory

location)

Press [P/M] to store and exit or go on-hook to abort

Go to 1 for storing further numbers

Programming Tone Ringer

Three different ringer melodies with three levels each can

be programmed. AS2534R cannot be programmed.

Press [P/M] to enter program mode

Press [#] for ringer programming mode

Enter Code to select ringer melody and volume(see

code table in section Tone Ringer (Melody/Volume)

Press [P/M] to store and exit or go on-hook to abort

1 Digit includes 0 – 9

When Code 0 (tone ringer off) has been programmed, the

device will automatically return to previous setting

(different from 0) by next off-hook.

Temporary MF

The procedure below assumes that the device is operated

in puls mode.

Go off-hook

Press [*] or [T/P] to switch to DTMF mode

Press [R] or [T/P] to switch back to PULS mode

Got to 2. to switch again to DTMF mode

Mode pin is connected to row 1, 2, 3, 4, or 5. When mode

pin = row 5, pressing the [*] key also transmits the tone by

MF selected. The [T/P] key (not AS2535) can be used

alternatively to the [*] key.

Automatic Dialing

The following procedure describes the dialing procedure

and the internal sequences:

Go off-hook

Enter the number by pressing digit, [M1]-[M12], [LNR]

or [MR] + digit

The number is internally buffed in the FIFO

Tone- or Puls-Dialing starts

Wait for connection

Got to 2 for entering postdialed digits

Postdialed digits are not stored but buffed in the FIFO.
