Achieve the local network connection (LAN):
The TOPEX VoiBridge equipment is connected on the local network (LAN) or to the Internet
through the standard UTP Ethernet cable (CAT-5). Since the switching system of the equipment is
auto – negotiation (10 / 100) and auto-crossover you can use:
a. a straight cable in case of connecting to a LAN (switch, hub);
b. a crossover cable in case of connecting the equipment directly to the Ethernet port of your
computer.
The b. kind of link is recommended when you connect to the Topex gateway in order to change
its IP address: if you connect directly to it, you can avoid both disruptions to the local network in case
of conflicting IP addresses, as well as loss of connection when you are in the middle of performing
changes.
The network cables are inserted with one end in the RJ45 connector (labeled ETH0 or ETH2)
from the TOPEX VoiBridge equipment, and with the other end into a PC, switch or hub. The Ethernet
connection directly to your PC is used for configuration of the equipment by means of the OAM
program.
