Connecting A Lan To An Ip Network; Confirming Sufficient Network Capacity For Voip - Talkswitch CT.TS005.003902 User Manual

In a typical small office environment, there are several computers connected
to an Ethernet switch, sometimes integrated into a router. A router handles
the connection between two or more IP networks. Routers look at the
destination IP addresses of the packets passing through and route them
accordingly. In a network that shares data and voice, it is critical that the
voice traffic has priority over the data packets. Some routers support Quality
of Service (QoS) functionality for this purpose. These routers are identified
as devices that support QoS, VoIP or prioritization.

Connecting a LAN to an IP network

Connect the TalkSwitch unit to a Local Area Network (LAN). The LAN should
be equipped with an Ethernet switch, router, and modem or gateway. The
router may have an integrated Ethernet switch. A PC should also be
connected to the LAN for configuring the TalkSwitch unit.

To share voice and data properly, your network requires an Ethernet switch.
A switch isolates the Ethernet ports from each other and only allows traffic
intended for the device connected to that port. This ensures that data traffic
doesn't compete with voice traffic. The most successful way to separate voice
and data traffic is to install a router using different subnets for voice and
data.

Confirming sufficient network capacity for VoIP

Ensure that the LAN in each location has a reliable high-speed broadband
connection to the Internet. The quality of VoIP calls, especially on mixed
voice and data networks, depends on high data-transfer rates across the
network. 'Lite' broadband connections are not suitable for simultaneous voice
and data traffic.
