Upconverter
75 ohm type F female connectors
Input signal frequency 44 MHz; level range +38 dBmV to +45 dBmV.
Output signal frequency 477 through 577 MHz; maximum signal level +60 dBmV.
100 Mbps Ethernet Switch
The Ethernet switch is the connection point for all TCP/IP data flow on the ARCi Internet
side of the gateway (subnet).
Subscriber traffic flows through the Gateway to the Internet via the Switch, as does
Network Management traffic to and from the WMTS and the Internet. Other devices such
as a laptop computer can be plugged into the switch provided that they are configured
with the proper TCP/IP addresses for the system subnet.
Network Manager PC
The network manager PC provides services to the ARCi Internet system such as DHCP,
TFTP, SysLog and time servers. It also provides remote operational visibility and control
into the ARCi Internet via SNMPc. Note that with appropriate address translation in the
Gateway, the Network Manager may be installed at a remote location such as the ISP’s
control center. See the Vyyo V3000 Wireless Hub Users’ Manual
for more detail.
The network manager PC also monitors certain parameters of the transmitter(s) and
receiver(s) located within the associated ARCi hubs. It also enables upstream frequency
selection for each hub receiver. [Telemetry support for this function will be available in
late 2002]..
Gateway / Router / Backhaul
This equipment provides functions required to interface the ARCi Internet system to the
backhaul transmission facility to the ISP, which will normally specify and configure this
equipment. It interconnects with the ARCi Internet system via a standard port on the
100 Mbps Ethernet switch.
Some notes on the gateway
Once it is configured and running, the ARCi wireless network is simply a standalone IP
network that requires the presence of a gateway through which packets are routed
between the ARCi network and the Internet. The network interface on the ARCi side of the
gateway must be 100baseT Ethernet. The gateway itself is typically one of two types
depending on the network IP address:
