ABLING
For the data line :
The IA12 ISDN Adaptor with the ISDN data cable. Like the telephone data
cable of the consoles and feature phones, the ISDN data cable is formed up of
two parts. One is a cable with a 6-pin RJ plug at both ends and the other one is
a connection box. The connection box has a 6-pin RJ socket at one side so
that one of the free ends of the cable can be fixed to the connection box easily.
The other free end of the cable has also the corresponding RJ socket at the
bottom part of the IA12 motherboard.
The signals on the connection box of ISDN data cable are the same as the
signals on the connection box of telephone data cable.
For making the data connection of the IA12 ISDN Adaptor :
1) The Data / + 12 VDC / GND signals on the connection box of the system
data cable must be wired in parallel to the corresponding pins of the
connection box of the ISDN data cable.
2) The RJ plug at the free end of the ISDN data cable must be attached to
the corresponding RJ socket at the bottom part of the IA12 motherboard.
For the S0 line :
By the help of a cable having 8-pin RJ45 plugs at both ends, the S0 line
coming through NT1 must be attached to the corresponding RJ45 socket at the
bottom part of the IA12 motherboard or EXP-IA12 card.
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 coming from the related line
connectors on MB48 motherboard or EXP48 card and passing through the hole
on the front panel at the down left corner of the system cabinet (the panel on
which system ON/OFF switch resides) 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.
