Figure 8 Direct Telephone Line Connection
About Pass-Through Telephone Line Connections
With a pass-through connection, the terminal uses a telephone
line that is shared by a standard telephone base unit (see
Figure 9). A pass-through telephone line connection is useful
when you want to save the cost of an additional dedicated or
leased line. There are, however, several disadvantages to using
a pass-through connection:
• You cannot make a normal call while the terminal is
processing a transaction, or when a remote host computer
is dialing in to the terminal.
• Lifting up the telephone handset during a transaction may
disrupt the audible data carrier signal and cause the
terminal transaction to fail.
• Two telephone line cords are required instead of one. (One
telephone line cord is supplied with the terminal; you can
obtain an extra cord from VeriFone or from any local
business supply store.)
