KP2, Code 11, Code 12 and 2400+2600Hz? #13
Description
KP2, Code 11, Code 12 and 2400+2600Hz are missing for a complete blurbox, Code 12 and 12 are special operator codes and a compound signal of 2400+2600Hz are used to seize a truck on international lines and then 2400 Hz to clear forward and then the trunk is ready for receiving routing information, KP1 for domestic calls and KP2+CC+0+number+ST for international.
Would be really nice to have a complete bluebox in the Flipper even though it is probably not useable these days...
