EXPRESS CONFIGURATION SOFTWARE
ADTRAN’s Express Configuration software, included with the Ex-
press 3000 SP, makes connecting to ISDN and configuring the Express
3000 SP easy. This software includes on-line help to assist you in
quickly and easily setting up your system (see also
Using On-line Help
on page 3-5).
ANALOG DEVICES SUPPORTED
The Express 3000 SP supports up to two analog devices such as tele-
phone, FAX machine, or analog modem in addition to the computer
connection for data transmissions. When transmitting data at maxi-
mum throughput over both B channels using Multilink PPP, the Ex-
press 3000 SP modem automatically detects calls on the analog ports.
Upon detection, the Express 3000 SP modem adjusts the speed of the
data call to 64 kbps using one B channel and accepts the analog/voice
call on the other B channel. After completing the analog/voice call, the
Express 3000 SP modem automatically resumes data transfer over
both B channels.
REMOTE ACCESS
Remote access gives Management Information Systems (MIS) manag-
ers the flexibility of adjusting the configuration of remote units over
the ISDN line.
