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).
