This chapter

This chapter provides information about the functioning, configuration and
conditions of the radio for the in-band signaling.

3.8.1

Introduction/Overview

Introduction

To  reduce  the  number  of  lines,  in  particular  for  transmitting  signals  over
long  distances,  the  use  of  the  bidirectional  in-band  technique  via  a  2-pair
AF/telephone  line  per  radio  unit  (receiver,  transmitter  or  transceiver)  is
recommended.

The R&S Series 4200 radios support the following in-band functions:



Signaling of SQ on receiver side



Audio in-band tones for RSSI signaling on receiver side

Signaling of SQ

SQ  can  be  indicated  by  a  tone  with  a  specified  frequency  that  is  present
within AF signal. If the In-Band signaling  is configured to  SQ, the  in-band
tone is generated when SQ is open (SQ threshold is met). If the parameter
is  configured  to  INVSQ,  the  in-band  tone  is  generated  when  the  SQ
threshold  is  not  met.  A  part  of  AF  signal  near  the  SQ  tone  frequency  is
suppressed by a notch filter. The squelch can be signalled via the RX audio
channel with the tones of 1225 Hz, 2040 Hz, 2175 Hz, 2440 Hz, 2970 Hz or
3300 Hz.

The level of the SQ tone is variable within specified range and is related to
nominal audio signal level set by “RX Audio Level”.

Signaling of STD

STD can be indicated by a tone with a specified frequency that is present
within AF signal. If the In-Band signal is configured to STD, the in-band
tone is generated when a simultaneous transmission is detected.

Audio in-band
tones for RSSI
signaling

At the RSSI selection one of four tone frequencies is generated depending
on  received  signal  strength  and  is  transmitted  via  the  in-band  audio
channel  (X10.2/X10.3)  (see  Fig.3.70  Tone  used  for  RSSI  signal  quality).
The  appropriate  low  pass  filter  is  used  in  order  to  suppress  received  AF
signal  in  the  affected  AF  range.  During  one  transmission  cycle  the  RSSI
signaling frequency is kept constant.

The level of the RSSI tone is variable within a specified range and is related
to nominal audio signal level.

Note:

Once the SQ criteria is met, the signal strength is evaluated. An

appropriate in-band tone is selected and kept unchanged for the whole
period (until the SQ release).

3390 Hz (good quality)

SQ criteria met, RSSI > 30 µV

3300 Hz (middle quality)

SQ criteria met, 6µV < RSSI < 30 µV

3210 Hz (bad quality)

SQ criteria met, RSSI < 6 µV

3180 Hz (no signal)

SQ criteria not met
