CABLING

Data Line:

The IA12 Data cable comes with the IA12 ISDN adaptor. Like the telephone data cable of 

the feature telephone sets and/or consoles, the data cable of IA12 also consists of two 

parts. One of them is a cable with 6-pin RJ jacks at both ends and the other is the connec-

tion box. There is a 6-pin RJ socket at one end of the connection box; one end of the cable 

is attached to the connection box. The other end of the cable is attached to the RJ socket 

at the right side of the IA12 motherboard.

Signals on the connection box of the ISDN data cable are the same as the ones on the con-

nection box of telephone data cable.

In order to make connection with IA12 ISDN Adaptor:

1-   Data / +12 VDC / Ground signals on the connection box of the system data cable are 

connected in parallel to the appropriate pins of the connection box of the IA12 data cable.

2-   The RJ jack at the free end of the IA12 data cable is plugged into the RJ socket on 

the IA12 motherboard.    

ISDN Line:

One end of a cable, whose pin order is one-to-one, and which has 8-pin, RJ45 jacks at 

both ends is attached to the RJ45 socket on the NT1 device and the other end to the RJ45 

socket on the IA12 motherboard or the EXP-IA12 card.

Analog Lines:

Each ISDN BRI line is converted to two analog lines.

A  pair  of  consecutive  lines  (such  as  lines  01,  02  or  03,  04),  of  an  MS  exchange  is 

connected to the clip-type connectors on the IA12 motherboard or the EXP-IA12 card. It 

is very important to pay attention to the order of lines, while making those connections. 

IMPORTANT

 THE FIRST CHANNEL OF THE IA12 MOTHERBOARD OR EXP-IA12 CARD MUST 

BE CONNECTED TO LINES WITH ODD NUMBERS (EX: 01, 03, 05…19) AND THE 

SECOND CHANNEL TO EVEN NUMBERED LINES.

INSTALLATION 

APPLICATION

The IA12 Adaptor has been designed to be mounted on the wall. In order to do that:

1-   Two holes are drilled into the wall with a distance of 17.5 cm in between.
2-   The anchor plugs are tightly driven to the holes.
3-   Screws are inserted into the anchor plugs and then fixed.
4-   The adaptor is hanged by coinciding the holes at the back to those screws.

IA12 MOTHERBOARD AND EXP-IA12 EXPANSION CARD  

IA12  motherboard  comes  in  the  cabinet.  That  card  has  been  fixed  with  lead  card 

holders. 

EXP-IA12 Expansion card, too, has been fixed with brass card holders to the motherboard. 

Communication between the IA12 motherboard and EXP-IA12 card is maintained with a 

20-pin flat cable. The figure below shows that connection.
