1 FEATURES

1.1 Pulse/DTMF dialling

• Pulse, DTMF and ‘mixed mode’ dialling

• Mixed mode dialling: start with pulse dial, end with

DTMF dial (e.g. for control of DTMF user equipment via

a pulse network)

• Number of digits per call is infinite (FIFO register)

• Flash or register recall

• Connect a/b to earth function

• Mute functions

• Disconnect function

• Supports 16 dial key: 0 to 9 and ∗, #, A, B, C and D

• Supports up to 6 × 6 keyboard and various function keys

including:

– FLASH: calibrated line-break pulse

– HOOK: toggle on-hook/off-hook or loudspeaker

on/off

– MUTE: activate/deactivate mute output

– TONE: change to DTMF dialling (mixed mode)

– DISconnect: return to on-hook state for calibrated

time

• On-hook dialling control

• Country specifications which can be stored in EEPROM

are:

– ∗ and # to be transmitted/not transmitted when

switching over to DTMF dialling mode

– mark-to-space ratio (3 : 2 or 2 : 1)

– 6 tone time selections (60/90, 70/70, 80/80, 100/100,

100/140 or 140/140 ms)

– 4 flash time selections (100, 115, 270 or 600 ms)

– mute output type selection (M1, M1, M2 or M2)

– microphone mute generated via the LSE output

– DTMF keys or Function keys selection

• On-chip voltage reference for stabilized supply and

temperature independent tone output

• On-chip filtering for low output distortion (CEPT

compatible).

1.2 Number storage

• Redial by ‘cursor’ method (maximum 24 digits) stored in

internal EEPROM

• Storage for 13 repertory dial numbers (16 digits each) or

10 repertory dial numbers (20 digits each) in internal

EEPROM

• Access pause generation and termination: manually or

by ‘Atlanta’ procedure

• Function keys for: LNR, Memory recall, Store, Access

Pause and 1 key repertory

• Country specifications which can be stored in EEPROM

are:

– access pause time selection (1.5/1.0, 2.5/1.5,

3.0/3.5 or 6.0/6.0 s)

– 10 number repertory dialler selection (1 or 2 key)

– two repertory number programming procedures

(General or Germany)

– repertory length (16 or 20 digits)

– generating a keytone during program actions.

1.3 Ringer

• Ringer input frequency detection

• Function key for: Program Ringer

• Three-tone ringer with 4 different ringer frequencies

• Ringer melody generation with four signal speeds and

four output volume steps, keypad controlled

• Country specifications which can be stored in EEPROM

are:

– ringer input frequency detection selection

– ringer output selection (via DTMF tone output or

special ringer tone output)

– 4 possible ringer melodies

– 4 possible ringer repetition rates

– 4 possible ringer volumes.

1.4 General

• On-chip oscillator uses low-cost 3.58 MHz (TV colour

burst) crystal or PXE resonator

• On-chip power-on reset (typically 2.0 V)

• Supply voltage range 1.8 to 6.0 V (2.5 to 6.0 V in

EEPROM erase/write and DTMF and ringer mode).
