Appeal No. 1998-2870
Application 08/429,954
OPINION
Apparatus claims 1-25
Biggs discloses an access phone 10 comprising a standard
telephone keypad 56, an amenity keypad 58, speed dial buttons,
and a credit card reader, or swipe, mechanism 62 (col. 6,
lines 10-13; col. 13, lines 52-63). The access phone 10 is
controlled by an internal central processor unit (CPU) 60 and the
programs are stored on an Erasable Programmable Read Only Memory
(EPROM) 70 along with other communication elements as shown in
the circuit of figure 3 (col. 6, lines 13-28; col. 13, line 52 to
col. 14, line 15). The EPROM 70 is programmable through a
program input 72 (col. 14, lines 8-9). The access phone 10
communicates with an external apparatus, such as store-and-
forward switch 20, using analog dual-tone multi-frequency (DTMF)
signals (col. 6, lines 17-21). The access phone 10 is line
powered such that when the access phone 10 is taken "off-hook,"
the system is activated (col. 14, lines 46-48). The CPU 60
receives stored information from a credit card via the card
reader 62, corresponding to the claimed "information signal" of
claim 1, and a signal from an amenity key, corresponding to the
"service select signal" of claim 1, and generates control signals
in response thereto which are used to send information to the
external apparatus (col. 14, lines 46-59; col. 15, line 66
col. 16, line 27); e.g., as shown in figure 5, the CPU 60
