Automatic conversion to and from the telex character set.  This means that you can write your message freely, without worrying about the limited character set being used on telex.  TCS will take care of converting the message for you.
	Automatic re-dialling of busy numbers or destinations which are difficult to reach.
	Possibility to check the answer-back, before delivering the message, e.g. 45-54321=XYZ the "XYZ" is then required to be part of the received answer-back, otherwise the message will not be delivered.
	Telex is still important especially in the banking and shipping sectors, due to its legal validity and wide availability in all parts of the world.
