Installing QuadroM-E1/T1
Networking Overview
To establish a connection between the PSTN (or your PBX) and the Internet, a VoIP gate-
way is needed. The QuadroM-E1/T1 is a VoIP gateway, and will perform the task of con-
necting your PSTN (or PBX) via its E1/T1 port(s) to a Private Data Network that includes
Quadro SIP routers (Quadro2x, -4x and/or -16x) or the Internet. The QuadroM-E1/T1 will
process and regulate the voice traffic between these networks by means of Call Routing
paths that are specified by the administrator according to a dial plan. The QuadroM-E1/T1
has one additional LAN port that is used to connect a PC for management purposes. Both
WAN and LAN ports transmit at 10 Mbps or 100 Mbps speed.

Every device within an IP network requires a unique IP address to identify itself. Since the
QuadroM-E1/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 QuadroM-E1/T1’s integrated firewall/NAT function-
ality 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/T1
can be configured with a static IP address on the WAN interface. You also can 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 QuadroM-E1/T1 acts
as a DHCP client on its WAN interface and as a DHCP server on its LAN interface.
