Airports with multiple terminals and other dispersed facilities must of necessity maintain a telephone network with multiple PBXs that service hundreds of telephones. In such applications, multiple PBXs are often connected over the same network over an SDH/SONET ring. RAD Data Communications, however, offers an alternative solution that simplifies and reduces the cost of maintaining such a network.
Rather than employ an expensive SDH/SONET ring, multiple PBXs can be connected over a T3 ring using RAD’s Optimux-45 fiber multiplexers.
The Optimux-45 provides a highly cost-effective and simple solution for transporting n x E1 or T1 circuits, as well as a combination of E1 and T1, over a T3 (45 Mbps) or fiber link. Featuring self-healing ring capabilities, the Optimux-45 integrates up to 28 T1, 21 E1, or combinations of T1 and E1 circuits (according to ITU G.747) into a 45 Mbps data stream for transport over a standard T3 electrical signal or fiber link.
With a maximum range of 110 km (69 miles) between two points, the Optimux-45 supports a wide range of applications and topologies that, besides campus rings, also include drop-and-insert for cellular backhaul, point-to-point over wireless links and point-to-point over SDH/SONET.
The Optimux-45 has a redundant power supply, enhancing system resiliency. An optional secondary link provides automatic backup, ensuring transmission reliability.
