Excalibur Multirate DAP Installation and Operation
5-36
Local Alarm Display
This parameter specifies whether the front panel displays alarms that occur at the local
DAP. (Incoming alarms are always displayed when the unit is configured for RCP
control.) When disabled, local alarms are not displayed on the front panel, but may be
reported to the CMS network management system.
Analog Regeneration
This parameter specifies whether the DAP's analog receiver regenerates secondary
channel signals through the digital transmitter. The normal setting for most networks is
Enabled.
Digital Regeneration
This parameter specifies whether the DAP's digital receiver regenerates secondary
channel signals through the analog transmitter. The normal setting for most networks is
Enabled.
Diagnostic Compatibility
This parameter specifies whether enhanced diagnostics are available. Since older DAPs
do not perform the new diagnostics, the Diagnostic Compatibility parameter simplifies
diagnostic testing by deleting the new diagnostics from the front panel menus. If you are
performing tests with Multiport or Multirate DAPs equipped with Software Revision No.
SSC0778 or lower, select On. To determine the software revision number of the unit,
enter the Status submenu, press the button beneath Unit, then press the button beneath
Revsn.
Route Secondary Channel
This parameter appears on the screen only for units equipped with the Analog or ISDN
IDBU feature. It specifies whether the secondary channel transmits data across the dial-
up telephone line, while the primary channel transmits data over the digital lines. When
the To Dial option is selected, you can establish a dial backup connection with a remote
Excalibur DAP and perform diagnostics and/or monitoring operations without affecting
primary channel data on the dedicated line. This option provides a remote DAP
operating in DDS or CC64 mode with a non-interruptive secondary channel and provides
a CMS network management system with T7 secondary channel connection to a remote
DAP.
