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.
