Dial-Out
The DGC-2020 uses telelocator alphanumeric protocol (TAP) version 1.7 when communicating with
paging companies. This data format

D

specifies seven data bits with even parity. If required, eight data bits

with no parity may be specified.
The message string sent by the DGC-2020 can be limited to a length supported by the receiving pagers

E

.

If a message to be transmitted by the DGC-2020 exceeds the pager message limit, the DGC-2020 will
make multiple calls to transmit the complete message.
Dial-out messages are sent by the DGC-2020 at a user-defined interval

F

. This interval gives an operator

the opportunity to dial into the DGC-2020. A second user-defined interval

G

determines how frequently

dial-out attempts are made following a dial-out failure.

Dial-In
When the DGC-2020 modem shares a line used for voice communication, the number of rings

H

required

for the modem to answer can be increased to allow time for an operator to answer an incoming telephone
call.
