Installing QuadroE1/T1
Networking Overview
To establish a connection between the PSTN (or your PBX) and the Internet, a VoIP gate-
way is needed. The QuadroE1/T1 is a VoIP gateway, and will perform the task of connecting
your PSTN (or PBX) via its E1/T1 port to a Private Data Network that includes Quadro SIP
routers (Quadro2x, -4x and/or16x) or the Internet. The QuadroE1/T1 will process and regu-
late the voice traffic between these networks by means of Call Routing paths that are speci-
fied by the administrator according to a dial plan. The QuadroE1/T1 has one additional LAN
port that is used to connect a PC for management purposes. The WAN port transmits up to
10 Mbps, and the LAN port transmits at 10 Mbps or 100 Mbps.
Every device within an IP network requires a unique IP address to identify itself. Since the
QuadroE1/T1 connects to both the LAN (Admin PC) and the WAN (Private Data Network or
Internet), it has to be part of both networks, and must have two IP addresses: one for the
WAN side and one for the LAN side. The QuadroE1/T1’s integrated firewall/NAT functional-
ity will hide the LAN IP address from the WAN (Internet) side.
There are two ways of assigning an IP address: statically or dynamically. The Quadro E1/T2
can be configured with a static IP address on the WAN interface. You can also use a DHCP
server assigned IP address on the WAN side.
Please Note: A DHCP client is software that requests an IP address from a DHCP server. A
DHCP server assigns on request a unique IP address to a device. The QuadroE1/T1 acts as
a DHCP client on its WAN interface and as a DHCP server on its LAN interface.
