The WMTS provides a full duplex 100BaseT Ethernet interface to the network IF. The
WMTS arranges the incoming Ethernet data frames, multiplexes (in TDM) and modulate the
downstream carrier. The WMTS also receives upstream information from the WMUs. It
demodulates the upstream signal, multiplexes TDMA-based data and provides it to the
network interface. It consists of the WMTS chassis, redundant power supplies, redundant host
cards, control and forward card, one downstream module, and up to five upstream modules.
3.1.1 Minimum System Requirements
• WinNT Workstation or Server that meets the requirements of a Pentium III 400 Mhz,
128 MbRAM, 6 Gb hard drive, network interface controller card, Internet browser such
as Netscape 4.06 or later or Internet Explorer 4.01 or later.
• ServicePro software installed on the server, which includes DHCP server, TFTP server,
ToD server, and the Alopa SNMP server
• Straight-through serial cable with DB-9 male and DB-9 female connectors
3.2 Router (Delete?)
The router is used for a network edge device, which will provide correct IP forwarding and a
WAN interface back to the main network devices.
3.3 Bandwidth Manager (Delete?)
The bandwidth manager is used to control flow to and from each WMU separately. It is
capable of setting both minimum guaranteed and maximum throughput for each WMU. This
device is capable of controlling flow on both IP address and type.
3.4 Receive Antenna
The US RF signal from the CPE is received with an antenna mounted on the tower at the base
station. The antenna is directed toward the desired upstream sector with the chosen frequency
of operation.
3.5 Headend Test WMU
The Headend Test WMU resides in the cabinet with the WMTS and is connected to the RF
pads through the use of the cg coupler and directional couplers with an appropriate attenuate.
It is designed to test the wireless link within a site prior to the RF leaving the building.
4 EMS (ELEMENT MANAGEMENT SYSTEM)
ADC's Axity Element Management System (EMS) manages the WMTS and WMUs. The
Axity EMS is an advanced functionality Web-based system. It communicates with managed
devices using the Simple Network Management Protocol (SNMP), and can be accessed either
locally or remotely over the Internet.
