1. DESCRIPTION

1.1 The tii SVM-2 Series Multi-Line Switchable
Voice Module is used when porting up to two
existing telephone numbers.

when the number is ported.

1.3 The tii SVM-2 can come equipped with an
optional secondary telephone line surge
protection to enhance Digital Phone service
reliability.

1.4 The SVM-2 should only be used for indoor
applications, if mounting outdoors the SVM-2
should be mounted in a weatherproof
housing.

1.5 The SVM-2 is powered from the Digital Voice
Service line, and switches to Digital Voice
Service after validating telephone ringing
voltage presence on this line. The green
LED will blink slowly when the SVM is
receiving power from the Digital Voice
Service Line.

1.6 The SVM-2 may be reset by using the reset
push button accessible on the side wall of
the device. The SVM-2 must be powered by
