30 CHAPTER 3: HARDWARE DESCRIPTION AND INSTALLATION
Installing Analog
Equipment
You can connect an analog touch-tone telephone, answ ering machine, fax
machine, or external analog modem to the ISDN LAN Modem. You will need an
RJ-11 to RJ-11 cable that is supplied with the analog device for each analog phone
port connection.
To install an analog device:
1Insert one end of an RJ-11 cable into one of the two analog ports labeled Phone
on the back of the ISDN LAN Modem, as shown in Figure 16.
Figure 16 Analog Equipment Connection
2Insert the other end of the RJ-11 cable into the appropriate RJ-11 port on the
analog device.
3If you have another analog device to inst all, repeat steps 1 and 2.
CAUTION: The ISDN LAN Modem is designed to operate with touch-tone
telephones that collectively do not exceed a ringer equivalence number (REN) of
three per analog phone port. The ISDN LAN Modem is designed to provide powe r
(25 mA loop current per phone port) a nd ringing for these devices on up to 61
meters (200 feet) of AWG 26 or heavie r AWG wiring. Although the ISDN LAN
Modem may function satisfactorily at longer cable distances with more than two
attached telephones, proper operation at longe r 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 ISDN LAN Modem’s Phone port. Bec ause
these devices do not conform to the powe r specification of the touch-tone
telephone standard, their operation is not guaranteed.
