ABLING
For the data line :
The IA12 ISDN Adaptor comes 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 is not used for connecting IA12 to
the MS128 system.
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) One end of the ISDN data cable must be passed through the hole on the
left cover of the system cabinet and connected to the ISDN socket on
MS128 CPUKON card.
2) The RJ plug at the other 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 KN1 card and passing through the holes on the side covers of
the system cabinet 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.
