Modem Access

The TTY interface can also be accessed through the phone line, but before dial in access is granted the user must
be set up as a modem user with Edit16S.
Under the Login tab select the User that will need modem access and make sure that the modem check box at the
bottom is checked. The password will also need to be set. Figure 12.7.1.1 shows a example of changes that need
to be made.
When dialing in, priority is given to voice. The voice will timeout waiting for a DTMF ID and the modem
should automatically establish a connection. Once a connection has been established, the user should see the
standard TTY interface password prompt. Enter a valid password to access the TTY menus. For an attached null
modem the following command would be sent to dial the unit:
ATDT<telephone number>
