Local Modem Connection 2
For a local modem connection, you must use a modem (either connected to, or
built into, the PC) to access the internal modem in the control unit. Connect the
modem to an 012 T/R or 016 T/R module in the control unit, as shown in Figure
2–3.
The internal modem operates at speeds of 1,200 and 2,400 bps.
