Appendix D: Power Source 2
(PS2)
The UT3620 is powered by an AC power supply
included with the unit. There are two options - the
16 Watt power supply or the 40 Watt power
supply.
The 16 Watt power supply can provide up to 16
watts of Power Source 2 (PS2) power. This power
supply is normally used for Video Conferencing,
Data Equipment, or fewer low-power ISDN
Telephones.
The 40 Watt power supply provides up to 40 watts
of PS2 power and is used for multiple ISDN
Telephones on all lines.
PS2 power is commonly used to power TE from
the NT1. Most data devices, such as Video
Conferencing units, do not require PS2 to
function.
Most ISDN Telephones, including those with built
in data capabilities, require PS2 power. The
specifications or documentation of the TE will
have information on the watts required by the
device.
