The 3ComImpact IQ External ISDN Modem (referred to as the
3C882 ISDN modem throughout this guide) is an external,
stand-alone Integrated Services Digital Network (ISDN) Basic
Rate ISDN modem for connection with digital telephone
services from local telephone companies in North America.
PCs and Apple Macintosh computers.
The 3C882 ISDN modem is designed for users who require
high-speed access to the Internet, intranet, on-line
information services, or corporate local area networks (LAN).
A typical 3C882 ISDN modem application is shown in
Figure 1-1.

the highest reliability and error-free performance possible.
With hi/fn compression and a high-speed serial port, the
3C882 ISDN modem allows you to reach transmission speeds
of up to 230.4 Kbps. ISDN technology reduces call setup
times by more than 50% compared to V. fast/V.34 analog
modem setup times; connection is established in 3 seconds.
Setting up the 3C882 ISDN modem takes only 15 minutes.
Simply connect the cables, load the software, run the SPID
Wizard™, and you are ready to place a call.
The 3C882 ISDN modem quickly processes data and voice
calls simultaneously. For example, you can send a fax or place
a voice telephone call while maintaining a high-speed
connection to the office LAN; you can also send or receive a
voice telephone call while you are connected to the Internet.
The 3C882 ISDN modem can be connected to any
compatible UL -listed computer that includes
RS-232-compliant serial ports.

Installing a Serial Cable
You will need the following type of serial cable.
■
For a Macintosh computer, you will need a 25-pin male to
mini DIN 8-pin male serial cable. Refer to the information
enclosed in your 3C882 ISDN modem package to order a free
cable. If you are providing your own serial cable, ensure that
it meets the pin specifications provided in Appendix C.
■
For a PC, you will need the 25-pin male to 9-pin female serial
cable that was provided. For PCs with a 25-pin serial port
connector, you will need to purchase a standard 9-pin to
25-pin adapter.

CHAPTER 2: INSTALLING THE 3C882 ISDN MODEM
To install the 3C882 ISDN modem serial cable:
1
Insert the 25-pin male end of a serial signal cable into the
RS-232 serial port on the 3C882 ISDN modem’s back panel
and tighten the connector screws, as shown in Figure 2-4.

Connect the other end of the serial cable to a serial COM
port on the back of your computer and tighten the
connector screws.
On a PC, most COM port connectors are labeled COM,
SERIAL, or RS-232-D. On an IBM AT® PC and most laptops or
notebooks, connect the cable to a 9-pin COM port connector.
If your PC has a 25-pin serial port connector, you will need to
install a standard 9-pin to 25-pin adapter.
On a Macintosh computer, the COM port is the mini DIN
8-pin serial connector depicted by the telephone handset.

CAUTION: An NT1 is built into the 3C882 ISDN modem.
Never connect the 3C882 ISDN modem ISDN port to a
standard analog telephone jack or to an external NT1 device.
Make sure that it is connected directly to the ISDN jack.
Installing Analog Equipment
You can connect an analog touch-tone telephone, answering
machine, fax machine, or external analog modem to the
3C882 ISDN modem.
You will need an RJ-11 to RJ-11 cable for each analog phone
port connection.
To install an analog device:

If you have another analog device to install, repeat steps 1
and 2.
CAUTION: The 3C882 ISDN modem is designed to operate
with telephones that are compatible with the original AT&T®
2500 touch-tone telephone standard. 3Com guarantees
proper operation of compatible touch-tone devices that do
not exceed a total ringer equivalency number (REN) of three
per analog port. The 3C882 ISDN modem is designed to
provide power and ringing for these three devices on up to
200 feet of AWG 26 or heavier AWG wiring. Although the
3C882 ISDN modem may function satisfactorily at longer
cable distances with more than two attached telephones,
proper operation at longer cable distances is not guaranteed
in all situations.
Installing the Power Cable
2-7
Specialized telephone equipment such as speaker phones
that draw large amounts of power may not work on the
3C882 ISDN modem’s Phone port. Because these devices do
not conform to the power specification of the 2500
touch-tone telephone standard, their operation is not
guaranteed.
Installing the Power Cable
To install the power cable:
1
Connect the 3C882 ISDN modem power cable to the
9 VDC power connector on the back panel of the ISDN
modem, as shown in Figure 2-7.
