DESCRIPTION
The MK53761is a Silicon Gate CMOS IC that pro-
videsnecessarysignalsforeitherDTMForloopdis-
connect(pulse)dialing. The MK53761buffersup to
18 digitsintomemory thatcan belaterredialedwith
a single key input. Up to nine repertory numbers
maybestored. Users canstoreall12signalingkeys
andaccessseveraluniquefunctionswithsinglekey
entries. These functionsinclude : LastNumber Di-
aled (LND), Softswitch,and Flash. Figure 2 shows
the keypadconfiguration.
A LNDkey inputautomaticallyredials the last num-
ber dialed. ThePROG keyprovides an easyway to
program a number into any memory location (1-9)
whetheron-hook on off-hook.The MEM key allows
easy redialing of the number stored in memory lo-
cations(1-9).
The FLASH key simulates a 560 ms hook flash to
transfer calls or to activate other special features
providedby the PABX or a centraloffice.
