Connecting the ISDN gateway
Before you start
Your ISDN connection
Outside North America
Check with your network provider to ensure that your incoming ISDN PRI line is
terminated in an NTU/CSU (Network Termination Unit/ Channel Service Unit). If
it is not, then seek their advice regarding the provisioning of such a device. Do not
connect the ISDN gateway directly to an external ISDN line.
Within North America
If your network provider has not terminated all of your incoming ISDN PRI lines
with an NTU/CSU, Codian recommends that you install a suitably approved CSU to
protect the ISDN gateway from damage by surges on your ISDN PRI lines.
IMPORTANT: Before installing the ISDN GW 3201 (ISDN gateway), you
must read the safety information at http//www.codian.com/safety.htm
To reduce the risk of fire, use only 26 AWG or larger telecommunication
line cord.
If you do not install a CSU between the incoming ISDN PRI lines and the
ISDN gateway, then the ISDN gateway must be installed in a restricted
location as defined by EN, IEC and UL60950. This is defined as an area
intended for qualified or trained personal only with access controlled by a
locking mechanism such as a key.
If you do not install a CSU between the incoming ISDN PRI lines and the
ISDN gateway, then you are required to connect the ISDN gateway to a
protective earth as follows:
Connect a protective earth cable (not supplied) to the terminals on the
rear of the chassis marked with the earth symbol .
Connect the other end of this cable to a true earth.
The earth terminal accepts two M4 screws on a 16mm (5/8") spacing for
use with a two hole copper lug (such as the Panduit LCD10-10A-L).
