DESCRIPTION
(continued)
When mated with a tone ringer, a complete tele-
phone can be producedwith just two ICs.
The DC line interface circuit develops its own line
voltage across the device and it is adjustable by
external resistor to suit different country’s specifi-
cation.
The speech network provides the two to four
wires interface, electronic switching between dial-
ing and speech and automatic gain control on
transmit and receive.
The dialing network buffers up to 32 digits into the
LND memory that can be later redialed with a sin-
gle key input. Additionally, another 13 memories
(including 3 emergency memories) of 18 digits
memory is available. Users can store all 13 sig-
nalling keys and access several unique functions
with single key entries. These functions include:
Pause/Last Number Dialed (LND), Softswitch,
Flash.
The FLASH key simulates a timed hook flash to
transfer calls or to activate other special features
providedby the PABXor central office.
The PAUSE key stores a timedpause in the num-
ber sequence.Redial is then delayed until an out-
side line can be accessed or some other activity
occurs beforenormal signalingresumes.
A LND key input automatically redials the last
number dialed.
FUNCTION PIN DESCRIPTION
C1, C2, C3, C4, R5, R4, R3, R2, R1
Keyboards inputs. Pins 1, 2, 3, 4, 24, 25, 26, 27,
28. The one chip phone interfaces with either the
standard 2-of-9 with negative common or the sin-
gle-contact(Form A) keyboard.
