For the analog lines :
An S0 line is converted to two analog external lines.
For connecting a pair of analog external lines corresponding to the S0 line on
the IA12 motherboard, the wires of the cable (CBL-16 cable or any similar
cable procured locally) coming from the related line connectors on CON1 card
must be attached to the two 2-pin connectors at the bottom part of the IA12
motherboard.
The same also applies to the analog line connection of EXP-IA12 Expansion
Board. However, before such a cabling is made, the sticker covering the empty
hole at the bottom of the IA12 cabinet must be removed, so as to access the
analog line connectors on the EXP-IA12 card.
IMPORTANT
The first channel of the IA12 motherboard or EXP-IA12 card must be
connected to an odd numbered line (i.e. 01, 03, 05,….,19) and the second
channel must be connected to the succeeding even numbered line.
As illustrated in the figure below, while making the analog line connection as
explained above, the first channel on the IA12 motherboard or EXP-IA12 card
must be connected to line 01 or line 03 or so on. Then, if the first channel is
connected to line 01, the second channel must be connected to line 02 or if the
first channel is connected to line 03, the second channel must be connected to
line 04 or so on.
The following figure illustrates the wiring between MS224 system and IA12
motherboard .
