the LMU modules.
First, take out the LMU modules belong to each necessary group
Open the back cover of the exchange and take out the group
paging assignment module carefully by inserting a screwdriver
into a slot next to the module.
In the LMU modules, numbers are arranged so that, when viewed
from the parts side with the connectors on the left, station
numbers run from top downward, for example, #200 - #207.
In the PIU modules, numbers are arranged so that, when viewed
from the parts side with the connectors on the left, paging
numbers run from top downward, for example PO ~ P7.
