Introduction

This module is very useful for testing the status of 10 telephone lines at a glance, in MDF or Pillar/Cabinet tag block. This module will be inserted in the  tag block. Each line will have lamp indication. Lines which are working will be indicated by glowing of lamps along with polarity of supply. For spare line lamp will not glow. For incoming ring on the line ,the lamp will flicker. Similarly  if  subscriber lifts the handset then  lamp will be dimly lit. For ISDN line lamp will be extraordinarily bright. For data circuit line, lamp will be very dim. Thus in one stroke we can get the status of all the 10 lines. This module is available for Pouyet type as well as Crone type tagblock.
