ISDN TE – 2N BRI Enterprise Connection

The connection type shown in the figure below provides communication via a
GSM/UMTS gateway without PSTN connection. The ISDN telephone sets are connected
to the NT port of the GSM gateway, while a mains adapter simulating power supply
from the PSTN is connected to the TE port. The adapter is available under Part No.

This type of connection is especially suitable for direct calls from an ISDN branch
network to a GSM/UMTS network.

Another possible connection type is NT, where gateway synchronisation is derived from
the PSTN BRI extension.
