A limited distance modem is used when peripheral devices are connected to
the NAC through a direct connection. If a direct connection cannot be
supported, a dial-up modem is used to connect the peripheral device or
Meridian MAX to the NAC through the public service telephone network
(PSTN).
It may be possible to use other modems for dial-up supervisor displays,
remote supervisor logins, or network links, provided they support the
correct subset of standard Hayes modem commands. A set of modem
responses must also be supported. Table 4-10 shows the list of commands
and Table 4-11 shows the list of responses that must be supported.
