Excalibur Multirate DAP Installation and Operation

Standard Features
The Excalibur Multirate DAP comes with a full complement of standard features, as
described in the following sections.
Menu-Driven Front Panel Display
The Excalibur Multirate DAP has a menu-driven front panel display that makes
monitoring, configuring, and testing the DAP quick and easy. The two-line LCD screen
guides you through the various operating procedures by displaying menu prompts on the
top line and selectable options on the bottom line. To select an option, simply press the
button beneath it. Figure 1-3 shows a typical menu display in which you are prompted to
select the DTE data rate. The LCD screen is backlit for ease of viewing. If two minutes
elapse without a front panel button being pressed, the screen dims to reduce power
consumption.

Remote Control Panel
The Remote Control Panel (RCP) feature allows you to control remotely located
Excalibur DAPs from the front panel of the local DAP. The RCP feature may be
activated by both central and remote DAPs. The only exception is when operating in
Interruptive Secondary Channel (Basic DDS) mode in a multipoint configuration, the
RCP function can only be started from the central unit. By entering the remote unit's
address into the local DAP's front panel, you can perform any operating procedure as
if you were at that site, with the following exceptions:
• The T7 address cannot be changed.
• The Digital Data Service mode and line speed cannot be changed.
• The End-to-End Error, V.54 Loop 2 and L2 Error, and the Local-Error and
Network-Error tests should not be performed.
