AT&T recommends a switched network topology. The topology refers to the network
virtual shape or structure and does not necessarily reflect the physical layout.
Switched networks involve connecting the network components to switches, rather
than hubs. This improves the network communication.
The Gateway routes calls between outside Public Switched Telephone Network
(PSTN) lines and the internal IP-based network. The Gateway provides four PSTN
ports for connecting up to four phone lines and one 10/100 Ethernet port for
connecting to the Ethernet network. Up to four SB67010 PSTN Gateways providing
up to 16 PSTN lines and 50 Desksets can be connected to the network, for a total
of up to 54 devices.
The system assigns the first Deskset to join the network Extension 200. It then
assigns each additional Deskset an Extension number in ascending order. Even if you
unplug a unit, its Extension number is reserved. If you want to remove a Deskset from the network, the Extension number must
be deleted. This ensures the Deskset does not tie up an extension. This Extension number may be changed or deleted by the
System Administrator using the Web User Interface (WEBUI) (see
Once the Desksets are connected to the same network, they find each other through peer-to-peer (P2P) discovery protocols and
automatically self-configure. Additional telephony and network configuration is administered through the WEBUI. In addition, up
to five of the system Desksets can be set up with cordless accessory Handsets and/or a Headsets. If you register a Handset and
a Headset to each of these five Desksets, you can use a total of ten registered accessories with this phone system.
Installation
All devices must be connected to the same Internet Protocol (IP) subnet or they will not
be able to communicate with each other. Confirm either that all devices are connected
to the same router, or that the first three octets of the IP address are the same for all
system devices. In most installations, all Gateways and Desksets connected to the
network obtain an IP address from the Dynamic Host Configuration Protocol (DHCP)
server. If there is no DHCP server present, the system devices create self-assigned link
local addresses. The Gateway displays its IP address in the Idle mode as shown in
"Phone Settings" on page
