This fixes error message for wrong trx type, catches the case of KeyError when trx_type is not part of the library. removes power setting from this function: power out of transceiver or at the input of span is nor defined in equipment Transceiver Signed-off-by: EstherLerouzic <esther.lerouzic@orange.com> Change-Id: I15fa7cc772ab5c1a8c7637738eb83c2ddffa1219
