Hi there,
I'm cleaning up my cellar and I found a EGM 35 GSM A-Bis field test
equipment.
Manufacture: GN Nettest ELMI
Typ: EGM 35
It is meant to tap in a E1 line and decode messages and also the voice
streams between BSC and BS. Comes with headset :)
If any body has interest, I am happy to send pictures off-list.
Regards
Miguel
