DSP Trace Output
The DSP trace output feature is for factory use only. It should only be used when
prompted to do so by Zetron Technical Support. Normally this feature should be turned
off. It is configured via the diagnostic port as follows:
uDCC88 v2.79 ------ dSP v3.17
Press "<ESC>,C,T" to enter the DSP Trace main menu:
---Press <ESC> anytime to return to this menu--- ?,Config : C
chA,chB,Options,Flash,dspTrace,<BS> : T
oN, oFF, Addr_list, Interval,<BS> :
At this menu you can turn DSP trace output on or off by pressing
N
or
F
respectively.
Enhanced Call Detection Mode
Overview
Enhanced Call Detection uses a combination of VOX detection, COR or LLGT detection,
and the channel's patch state.
Enhanced Call Detection (VOX+COR or VOX+LLGT) operates as follows: When the
channel is patch-enabled, the start of a call is only recognized when either COR or LLGT
goes active (active-going VOX transitions are ignored). When the channel is not patched,
the start of a call is recognized when one of COR, VOX, or LLGT go active. The end of a
call is recognized only when COR, VOX, and LLGT are all inactive, no matter what the
channel's patch-state is.
LLGT detection, available only with an iRIM, does not require a preceding HLGT burst
and is set to a default threshold of -35 dBm. The iRIM is programmed to output its LLGT
signal to the UDCC at -25 dBm, which is 18 dBm below the
Audio Level To Console
parameter, configurable in the iRIM.
When the VOX+COR/LLGT mode is enabled, if either COR or LLGT is active, the
UDCC will deny all transmit requests if the BTI switch is ON (see
Requirements
• Universal Dual Channel Card with firmware version 2.78 or newer
• The VOX+COR method requires a radio with COR output
• The VOX+LLGT method requires a Zetron iRIM for Kenwood or EFJohnson
radios with firmware version 1.68 or newer
Configuration
There are two methods of detection that can be configured: VOX+COR or VOX+LLGT.
Some steps in the procedure can be skipped depending on which method you are using;
this is identified at each step.
