Identifing a connector pair
I believe what this connector is older(!) 24-pin so called cellular phone dock connector compliant to older TTAS.KO-06.0028/R2 Korean national standard.
Important!
I emphasized older because this TTAS.KO-06.0028/R2 standard has been superseded by TTAS.KO-06.0028/R4 which have 20 pins instead of 24.
