Chapter 3 – Operation
About the Front Panel
The LED indicators on the front panel indicate status, configuration, and activity:
TD – Transmit Data. Flashes when the modem is transmitting data to another modem.
RD – Receive Data. Flashes when the modem is receiving data.
CD – Carrier Detect. Lights when the modem detects a valid carrier signal from another modem. It is on when the
modem is communicating with the other modem, and off when the link is broken.
OH – Off-Hook. Lights when the modem is off-hook, which occurs when the modem is dialing, online, or answering a
call. Flashes when the modem pulse-dials.
TR – Terminal Ready. Lights when a communications program is using the modem. It means the modem is ready for an
outgoing or incoming call. It goes off when the communications program disconnects the serial port. When it goes
off, a connected modem will also disconnect.
Power. The Power led lights when the system is applying power to the modem.
Leased-Line Operation
The MultiModem ZBA modem can be used on a two-wire leased line.
A leased line is a private, permanent telephone connection between two points. Unlike normal dialup connections, a
leased line is always active. The modems automatically connect when they are attached to the line and are turned on.
Because a leased line is always active, one of the two modems on the line must be configured as the originate modem
and the other as the answer modem; however, it does not matter which is which.
In the event of an interruption, leased-line modems automatically reconnect when the data line or power is restored.
Setup
1. Open the modem and change jumper J2 to select leased-line operation, and jumper J3 to select either
originate or answer operation, depending upon how you intend to use the modem. See Chapter 2 for the
detailed procedure.
2. Connect a modular telephone cable to the LINE jack. Connect the other end of the cable to a two-wire
lease-line jack or terminals supplied by the telephone company.
3. Turn on the modem. :
