Ready for operation?
– After a brief self-test, the power LED
lights up continuously. Green LAN LEDs show which LAN
connectors are being used for a connection.
Devices with integrated ADSL modems can become very warm
during operation. For these models, environmental temperatures are
not to exceed 35°C. Sufficient ventilation is of vital importance. Do
not stack the devices and do not expose them to direct sunlight.

Configuring the ISDN and analog interfaces
Swyx VoIP Router routers feature several interfaces for connection to
ISDN or analog exchange lines, or for connecting ISDN or analog
terminal equipment.
2.5.1
ISDN interface in NT or TE mode
Depending on the model, the ISDN interfaces can be used for
connecting to an ISDN exchange line or for connecting up ISDN
terminal equipment. The interfaces are switched into the NT or TE
mode for this:
• ISDN TE interface ("external ISDN connection"): An ISDN
interface in TE mode for connection to the ISDN bus of an
upstream ISDN PBX or to an ISDN NTBA. This ISDN interface
can be used for backup connections over ISDN or as a dial-in
interface for remote stations.
With the SwyxConnect 1723, the ISDN2 interface can be switched
into TE mode, but it must not be connected to the telephone network
(NTBA), either directly or indirectly via a PBX (by means of relay/
emergency switching)!
• ISDN NT interface ("internal ISDN connection"): With its ISDN
interface in NT mode, the Swyx VoIP Router itself provides an
internal ISDN bus. This ISDN interface can be used to connect
ISDN PBXs or ISDN telephones.
The factory settings have the ISDN interfaces marked with
⌧
set to
TE mode and the ISDN interfaces marked with
set to NT mode.
These ISDN settings can be altered according to your requirements:
• Multiple TE interfaces provide, for example, all available B
channels as a backup or for dial-in.
