XV. INTEGRATION OF EXPANSION CARDS TO
THE SYSTEM
XV.1. CON LINE CONNECTION CARDS
The CON2, CON3, CON4, CON5, CON6 and CON7 line connection cards constitute the
connection between two parties, namely telephones and lines on one side, and the extension
and line cards of the system on the other side. Over-voltage protection circuits, the line-busy
LED, grounding leads and line connection connectors are available on the line connection
cards.
There are four female RJ45 connectors on the CON2, CON4, CON5, CON6 and CON7
cards. The MDF cable with 16 pairs, which is called CBL-16, is for those CON cards. The
male RJ45’s at one end of the CBL-16 cable are attached to the corresponding female
connectors on CON card. Cable pairs at the other end of the CBL-16 cable should be
attached to the related sections on the distribution frame.
There are two female RJ45 connectors on the CON3 card. The MDF cable with 8 pairs,
which is called CBL-8, is for CON3. The male RJ45s at one end of the CBL-8 cable are
attached to the corresponding female connectors on CON3. Cable pairs at the other end of
the CBL-8 cable should be attached to the related sections on the distribution frame.
The CON cards are installed on the component side of the related expansion card. The 20-
pin connectors on component sides of the CON cards are plugged into the corresponding
connectors on the component side of the expansion card.
The cables CBL-8 and CBL-16 are supposed to be connected correctly in order not to
experience any problems while removing the expansion modules from the exchange and
replacing them back.
It would be convenient to pull the cables that extend to the line connection connectors
alongside the expansion card connector (20-pin, white connector) in order to reduce the
space they occupy. Fixing the line connection cables tightly to the expansion card by a cable
tie in such a manner that their thin sides would touch the card would ensure a trouble-free
installation.
