The VP 300 requires pin 4 (RTS) to be TRUE or left open, and pin 20, Data Terminal Ready (DTR), to
be TRUE. It is required that the modem provide DCD (pin 8) and CTS (pin 5) at the modem
connector, i.e., DTR (pin 20) and RTS (pin 4) at the VP 300 connector. Cable the modem to either the
front or rear VP 300 system terminal port. If you have a problem or question connecting your modem,
call Toshiba.
Once the modem connection is established, press
repeatedly (until the password prompt
appears) and follow the procedures outlined in the Communicating with the System section of this
chapter.
■
Connecting to the Internal Modem
The VP 300 has an internal 300/1200 baud modem. The internal modem can be accessed either by
entering
# # # 5
after the VP 300 answers, or beginning with Release 7.1, via a modem access
mailbox.
Connecting to the internal modem using
# # # 5:
:
1.
Call the VP 300.
2.
When the VP 300 answers, enter
# # # 5
.
3.
After the high-pitched tone, enter the code to connect to the modem (ATD). The code may
vary, depending on interface and modem manufacturer.
If you do not hear a high-pitched tone, repeat steps 1 and 2.
4.
Hang up the receiver if step 3 was successful.
The VP 300 automatically adjusts to the modem’s baud rate, which must be either 300 or
1200 baud.
Modem Access Mailboxes
Beginning with Release 7.1, to provide additional system security, access to the internal modem can be
restricted to specific modem access mailboxes.
To create a modem access mailbox, assign COS Attribute 118 — MODEM ACCESS and Attribute
3 — ASK FOR SECURITY CODE BEFORE CALLING EXTENSION, to the mailbox COS. The
mailbox should have a security code assigned before Attribute 3 is added.
