Connecting an ISDN phone or a G4 fax machine
Before connecting to the ISDN interface
To connect a phone or a fax machine to one of the ISDN connectors, you need an ISDN cable with
an ISDN connector. For specifications and pin-out, refer to ISDN interface, 2-port on page 178.
Connecting to the ISDN interface
The ISDN interface supports connection of up to 8 devices per ISDN interface. However, if you are
going to connect more than one device per interface, the devices must be self-powered. The ISDN
interface can supply maximum 1 W.
The Core network presently only supports one 64 kbps ISDN channel per subscription.
Do as follows:
1. Connect the ISDN cable to your phone or fax machine.
2. Connect the other end of the
cable to one of the ISDN
connectors on the
EXPLORER 700.
3. Power up the EXPLORER 700 and point the antenna as described in Pointing the antenna on
page 26.
4. Check the connection by making a phone call or sending a fax.
See Making or receiving a phone call with the EXPLORER
®
700 on page 62 or Sending or
receiving a fax message on page 68.
If connection fails, check that the interface is enabled in the EXPLORER 700.
If the ISDN icon is not present in the display Main screen and in the Dashboard in the web
interface, the interface is disabled.
See Enabling or disabling an interface on page 54.
If the interface is enabled, but connection fails, refer to the Troubleshooting Guide on page 161.
Important The ISDN interface on the EXPLORER 700 is powered by default. If your ISDN
equipment is self-powered, remember to disable the 38 V power. For information
on how to disable power on the ISDN interface, see Configuring the ISDN interface
on page 132.
Important The ISDN interface and the LAN interface use the same connector type. Be
careful not to connect to the wrong interface.
