Optical Talk Set Function
This function is available as an option with the OTS modules. It consists of a
headset and microphone.
It allows two users situated at each extremity of an optical link to communicate.
Each extremity of the link must be equipped with a combined Laser source/
Power meter:
•
two MTS
e
, each equipped with an OTS module with the Talk Set option.
•
an MTS
e
(equipped with an OTS module with the Talk Set option) and an
OTS type 7940X (with Talk Set option).
The Talk Set function can be in three states:
•
not selected (the icon shaded).
•
selected but not active (icon light with headset light): the standby mode,
ready to receive a transmission.
•
selected and active (icon light with headset dark): communication has been
established.
Establishing communication
1.
At each extremity of the fiber:
•
Connect the Laser source of one of the OTS to the Power meter of the other
and vice versa, with the aid of two jumpers or two optical links.
•
Plug the headset plug into the corresponding socket on the rear panel of the
OTS module.
2.
If the instrument calling is an MTS
e
, press the
SET-UP
key and validate the
Talk Set function from the Instrument Configuration menu (see page 3-12).
•
the Talk Set icon becomes light with the headset light.
•
The
icon appears at the top of the screen.
•
A message is sent to the other extremity of the fiber and an audio signal is
given from the receiving instrument.
3.
If remote instrument is ready to receive a communication (in standby), it
transmits a validation signal to the calling instrument.

The MTS
e
Talk Set icon becomes light with the headset dark.
•
Telephonic communication can be established.

If the remote instrument is not ready to receive a communication (Talk Set
function not validated): the icon remains light with the headset light. It
becomes light with the headset dark as soon as the correspondent calls.

e
, press the <Select> key to
disable the Talk Set function. The icon is displayed shaded.

this function is validated at the same time as the OTDR module, it is
possible to call a correspondent during an acquisition.
