Site Preparation

This section describes how to prepare your site for a successful Synapse system installation.

Network Requirements

For more information on the network configuration, see
A switched network topology is recommended for your LAN (using standard 10/100 Ethernet switches that carry traffic

at a nominal rate of 100 Mbit/s).
The office LAN infrastructure should use Cat.-5 (or better) cable.

The LAN connections to Synapse devices should all be wired. However, wireless connections to other devices (such as

laptops) in your office network that are not part of the Synapse system will not impede performance.
All devices in the Synapse system must reside on a single subnet.

A DHCP server is recommended and must be on the same subnet as the Synapse system so that IP addresses can be

auto-assigned. If no DHCP server is present, you can assign static IPs if desired. DHCP or static IPs are only required if
the system is to be managed from an external network. Synapse devices will self-assign link-local IP addresses for all
voice communication in addition to any DHCP or static IPs that are assigned for management purposes.
Unless you want to manually set the Synapse clock and upgrade Synapse software, an Internet connection to the LAN is

required.
A DNS server is recommended to resolve the path to the Internet and to the AT&T server for software upgrades.

If a routing path to the Internet is not available, the system administrator can download the upgrade files and use the

WebUI to upgrade the software manually.
For users whose computers require a GigE Ethernet frame rate (a gigabit per second), use separate Ethernet connections

for the Deskset and the computer. The Ethernet connection through a Deskset is limited to 100 Mbits/s.
