SECTION 1 INTRODUCTION
1.1 SCOPE OF MANUAL
This manual covers the functions of HP Open-
View and the E.F. Johnson application that are avail-
able when logged on with the operator password.
Alarms can be monitored and acknowledged, and
some program options can be set. Access to a com-
puter running OpenView and the E.F. Johnson applica-
tion as well as familiarity with Windows® NT and
networks are assumed. If menu selections and options
are available that are not covered in this manual, con-
sult with the System Manager before using them.
1.2 CONVENTIONS
Menu item selections are written similar to:
Monitor -> Status Legend
This example means to pull down the Monitor menu
and select the Status Legend item.
Ctrl+click means to press the Control key (nor-
mally labeled Ctrl) while clicking the mouse on the
desired location.
Keyboard shortcuts are written similar to:
Ctrl+Alt+Del
Ctrl+S
Press and hold the keys in the order written and then
release all keys. Each keyboard key is separated by a +
sign. Example: Ctrl+S means press and hold the Ctrl
key, press the S key, then release both keys.
1.3 DEFINITION OF TERMS
Multi-Net Signaling - The format of the data mes-
sages that are used to control trunking. Data messages
contain over-the-air instructions, or update informa-
tion, about incoming calls and free channels. Multi-
Net signaling also provides many enhanced operating
features such as unique ID calls and access priority.
Multi-Net System - A trunked radio system that uses
E.F. Johnson Multi-Net signaling. Other types of sig-
naling can also be used. A Multi-Net system can be
one site or multi-site. Each site uses a different set of
channels and radios can be trunked between sites.
Network Management - A computer system that
monitors the radio system for significant events. These
events are sent to a host computer where they can be
responded to manually, or in some cases automatically.
Reverts - Actions that are automatically performed if
failures occur. These actions are configured and per-
formed through network management.
Simulcast - A transmission method where several
sites that have overlapping coverage areas use the
same channels. All sites have a repeater on each chan-
nel. All repeaters on the same channel are synchro-
nized so they will transmit the same message at the
same time and phase.
Simulcast System - A system whose transmission
method is simulcast and whose trunking method is
Multi-Net signaling. Simulcast systems are also moni-
tored by network management.
Site - Repeaters and/or other network equipment that
is physically located together. Each site includes one
computer that is part of the network management sys-
tem. Sites can be collocated.
Stand-Alone Multi-Net Site - A site that uses Multi-
Net signaling, but will not trunk to other sites that use
Multi-Net signaling. None of the enhanced operating
features provided by Multi-Net signaling are available
at these sites.
Trunking - The automatic sharing of channels in a
multiple repeater system.
