PASS`AN - Critical Communications World

PASS’AN
Radio over IP Gateway
PASS’AN is an IP gateway allowing the connexion on a LAN or WAN of one or two radios TETRA or
Analog. These radios can then be operated from Prescom operator stations.
Transceiver commands by loop and RS232
Connection of the gateway to one to many
control centres
Digital signal processing technology allowing
reliability and scalability.
Speech coding over IP in G711 (64kbps) or
G723-1 (6,4kbps) in compress mode
