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.

2 Plug the transformer end of the power cable into a surge-
protected standard 110 VAC wall outlet.
The indicator LEDs on the front panel (see Figure 2-2) flash
momentarily as the unit undergoes a power-up self-test
diagnostic.
