On the 2174/S model, the RJ-45 port labeled
is the POTS/ISDN inter-
face. A telephone may be connected to this port and carried over the
CopperLink line. The units do not need power for the POTS interface to
work. The RJ-45 connector in the POTS/ISDN interface is wired as
shown in Figure 6.

3.4 CONNECTING POWER
The Model 2174 does not have a power switch, so it powers up as soon
as it is plugged in.
An external AC or DC power supply is available separately. This connec-
tion is made via the barrel jack on the rear panel of the Model 2174. No
configuration is necessary for the power supply (See Appendix B for
domestic and international power supply and cord options).
DC power (supplied via the power supply jack to the 2174) must meet
the following requirements; DC power supplied must be regulated
12VDC ±5%, 1.0A minimum. Center pin is +12V. The barrel type plug
has a 2.5/5.5/10mm I.D./O.D./Shaft Length dimensions.
The Interconnecting cables shall be acceptable for
external use and shall be rated for the proper applica-
tion with respect to voltage, current, anticipated tem-
perature, flammability, and mechanical serviceability.
