STAM-1 TRNK
stam1trnk_e_09/05
The STAM-1 TRNK card is used for expansion of functional capabilities of the STAM-1
monitoring station. It enables a trunking radiotelephone, which supports the MAP27 data
transfer protocol, or the SATEL GSM module (GSM LT-1, GSM-4), to be connected to the
station, thus making monitoring possible by radio (radiotelephone), by means of SMS
messages, or CLIP-type messages (GSM telephone).
