Radio connection gateway

The gateway for connecting of base radio station provides interfacing between a base radio station and digital Armtel DCN and IPN systems. The gateway enables to connect base radio stations such as MOTOROLA GM340 and GM360 or similar to analogue interfaces of the above mentioned systems for communicating with radio network subscribers. The gateway is located near a base FM-radio station or mounted in telecom cabinets or racks, control rooms or office premises.
