Rj11 (Ulp Models) - MTX -3G-JAVA series User Manual

4.1.3 RJ11 (ULP models)
An RJ11 6‐way connector, as shown and described below, serves as a means of supplying and
controlling DC power to the modem.
The power supply voltage (VCC) required by the modem is in the range of 6.5 to 10VDC (9.8 to
13.9VDC can be ordered upon request). The power supply has to be a single voltage source capable
of providing a current peak during an active transmission. The uplink burst causes strong ripples
(drop) on the power lines.
Application of the power supply voltage to PIN 1 does not switch the modem on by default. The user
has to use whatever wake‐up source once the modem is powered.
