Best way how to connect PRIGW unit into your telecomm. site:
Connection with 2x PRI BOARD (connection to PSTN <> PBX trunk):
Connection between two PRI equipments
In case that system is switched off or has some SW problem (uploading firmware), switches on PRI board
automatically disconnect PRIGW and makes direct connection between your switch and PSTN network.
* port mode (NT, TE) and Synchronization (MASTER, SLAVE) must be different on the switch than on the
PRIGW! TEI management number must be same on both equipment units!
