· Twenty by 16 digits for one-touch direct or two-touch indirect repertory memory

· Uses 6 ´ 10 keyboard

· Pause, Pulse-to-tone (*/T) and flash can be stored as a digit in memory

· Minimum tone output duration: 87 mS

· Minimum intertone pause: 87 mS

· Tone/Pulse mode pin selectable

· Make/Break ratio pin selectable

· Dialing rate (10 or 20 ppS) pin selectable

· Pause time (2.0 or 3.6 Sec) selectable by keypad

· Flash break time (100, 300, or 600 mS) selectable by keypad

· Built-in 12 or 16-digit LCD driver (1/4 duty, 1/3 bias) selectable by mask option

· Built-in calling timer from [00:00] to [59:59]

· Uses 3.579545 MHz TV quartz crystal or ceramic resonator

· Uses 32768 Hz crystal as RTC frequency base

· Packaged in 80-pin plastic QFP with RTC

· Provides one-key-redial and auto-redial functions

· Switchable 24-hour clock or 12-hour clock with p.m. mode

· 0 or 9 dialing inhibition pin for PABX systems or long distance dialing lock out

· On-hook debounce: 150 msec in normal mode and 20 msec in lock mode

· Off-hook delay 300 mS in lock mode (i.e. DP will keep low for 300 mS while off hook)

· First key-in delay: 300 msec in lock mode

· MUTE key for speech mute

· Cascade and mixed dialing allowed
