Connecting the VOE to the ISDN terminals
The VOE comes with an ISDN BRI (NT) port located on the rear panel (see
figure 2
on page 16) for connecting
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 B, “Cabling”
on page 40) connect the BRI (NT) port on the VOE to
the TE of the ISDN terminal (phone, PBX, or residential S-bus).

Note
The VOE BRI (NT) port delivers ISDN line power to any
connected terminals.
For details on the BRI port pinout and ISDN cables, refer to
Appendix B, “Cabling”
on page 40 and
Appendix
C, “Port pin-outs”
on page 43.
Connecting the VOE to the IP network
The VOE 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 VOE 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.
