Installing Analog Equipment 2-7
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 up to three compatible touch-tone devices per
analog phone 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.
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.
