Dear All,
Does anybody have any information on the type approval specifications for
the connection of 2-wire analogue terminal equipment for Russia. In
particular I am trying to find;
A reference for the applicable specification and where it may be
obtained
The on-line impedance (600R ???)
The correct DTMF signalling levels to line
SLR/RLR values for handset telephony
Details of the artificial line segments
Any information received would be greatly appreciated.
