Modem Cable Connections
When using a modem connection, you need to make the following cable
connection between the Passport 4400 unit and the modem to which it is
connected:

to the Passport 4400 management port
• Connect the DB-25 end of the Passport 4400 management cable (cable
number NTAU17AA) to a null-modem. (You may need a 9 pin-to-25 pin
RS-232 serial port adapter, or a female-to-female 25-pin adapter, to
make this connection.)
• Connect the null-modem to the modem
