2.3.6 Upstream Application
The upstream application is loaded in the universal card, which is part of the upstream
module. The application provides the proper RF input signal.
2.3.7 Controller and Forwarder Application
The control application performs all monitor, control, system configuration, provisioning, and
connection management tasks. It uses a realtime operating system kernel and is designed to
manage various processes such as Simple Network Management Protocol (SNMP), Telnet,
and other control tasks. It controls the redundant 100BaseT Ethernet interface for
communication to the servers and the two RS-232 console ports for out-of-band management.
The forwarder application provides buffering, packet processing, and forwarding of all normal
user data.
The control application uses non-volatile memory to retain configuration, system log, and boot
up files, and system images. New images can be downloaded from either the local RS 232
interface or remotely over the Ethernet interface. When a new chassis is powered up, the
system is set to the factory default configuration and it may have to be reconfigured for the
site requirements.
The controller and forwarder application is loaded in the universal card located adjacent to the
host card.
2.3.8 Power Supplies
The WMTS is powered by redundant AC power supplies with an operating range of 90 to 264
VRMS at 47 to 63 Hz. Although the system supports two load-sharing power supplies, one
power supply is sufficient for a fully loaded chassis of any configuration. Each power supply
is fused separately to allow redundant feeds.
3 WMTS PHYSICAL DESCRIPTION
The WMTS is illustrated in Figure 2-3. The chassis has a fan tray above and below the unit to
bring the total height required in the rack to 8U. The eight bay chassis contains eight slots in
the front, seven slots in the rear, with a mid-plane card in between to interface the cards. (the
16 bay chassis contains 16 slots in the front, 16 slots in
the rear.) The host cards have blank
panels. In addition, blank panels cover any unused slots.
