TLE-02D
Portable Digital Communications Unit
10
Selector Switch for ISDN-Analogue Telephone Line Mode (MODE SELECT ISDN/ANALOG
TELEPHONE LINE):
This selects the required line type (ISDN - CTN).
Important: To change the line type selection the equipment must be switched-off and restarted
with the new configuration.
.
Dial mode selector switch Pulse – DTMF Tones in CTN mode:
This switch selects the dial mode by Pulse or by DTMF Tones, allowing generating DTMF tones
to effect remote control operations in mode CTN.
4 Wire Interface
Full Bandwidth (20Hz-20KHz). Whether the unit is used as an Audiocodec on ISDN or as a
portable Telephone Hybrid on CTN, the transformed balanced 4W input/output is always
available, being operative to use it simultaneously with any of the two modes.
The return input has a level adjustment (TRIM) and it is permanently routed to the headset
outputs. Therefore it can be used for the connection of other Auxiliary signals that could be
required to be monitored by the reporters, such as Guides, Cue, P.A., International Sound, etc.
The Aux. out has also a mix control for the send and return signals (SOURCE), in this way
increasing the possibilities of the equipment which can be used as per the following examples:
- As a conventional 4W circuit, or a pre-mixer, setting the associated control knob
SOURCE in TX position.
- As a recording output, setting the associated control knob SOURCE in an intermediate
position TX/RX. This way, both program and return signals are available at the Output.
- As an auxiliary output of the digital hybrid, setting the associated control knob
SOURCE in RX positions. This way the unit can be connected to other equipment or to
a loudspeaker in order to use the hybrid as a hands-free telephone.
4 Wire Interface Auxiliary Input level adjustment:
The 4 wire interface auxiliary input level can be adjusted with the Trimmer (LEVEL TRIM)
located next to the interface.
Power supply:
Power is delivered to the Unit by the supplied AC-Adaptor or another suitable power supply,
through the DC-INPUT connector.
