Connecting the S-DTA to the ISDN terminals
The Smart-DTA comes with an ISDN BRI (NT) port located on the rear panel (see
figure 2
on page 15) for con-
necting to the TE port of an ISDN terminal (phone, PBX, or residential S-bus). Install the connection as follows:
1. Using an ISDN cable (see
Appendix C, “Cabling”
on page 46) connect the BRI (NT) port on the Smart-
DTA to the TE of the ISDN terminal (phone, PBX, or residential S-bus).

Note
The S-DTA BRI (NT) port delivers ISDN line power to any
connected terminals.
For details on the BRI port pinout and ISDN cables, refer to
Appendix C, “Cabling”
on page 42 and
Appendix
D, “Port pin-outs”
on page 45.
Connecting the Smart-DTA to the IP network
The Smart-DTA comes with a 10/100 Base-Tx Ethernet port for connection to an IP network. The Ethernet
WAN interface is factory-configured as a DHCP client, so you must connect the Smart-DTA to an IP network
that provides a DHCP server.
The Ethernet port (ETH) includes an automatic MDX (auto-crossover) feature that automatically detects the
cable configuration and adjusts accordingly. The feature allow you to use a straight-through Ethernet cable to
Never use an external Phantom supply!

Other pins are not used.
