Connecting the Cables
The ports on the rear panel are arranged in two groups.
Modem Lines 1-3
Each modem port has two connections:
Dial Line
(1, 3 & 5) The upper RJ45 connection in each pair
connects
to a normal dialled service, use this port to
connect your
modem to the line. In some countries you may
need to use an adapter to connect to your PSTN service
provider’s socket.
If you use a two into one line adapter, a telephone
handset can be connected in parallel to your modem at
the PSTN outlet. In this case you must not lift the
telephone handset during data transmission. If it is lifted,
any noise in the surrounding area interferes with the data
and can cause corruption in the transferred data.
Private Line
(2,4 & 6)
The lower RJ45 connection in each
pair connects to a private line. Use this port to connect
your modem to the line. In some countries you may need
to use an adapter to connect to your PSTN service
provider’s socket.
DTE Ports 1- 3
(7,8 & 9)
Connect DTEs 1 through 3 to these ports using V.24
modem cable as described in
AppendixA
.
The DTE ports also allow direct access to the Triple Modem
Module’s management system using a PC or terminal. This
removes the need to access the Triple Modem Module
through the AccessBuilder 7000 Management Controller
Module.
