Technology

The prototypical TTM solutions consist of a three layer network design. A fiber fed end cell site is connected via a fiber lateral to a fully route diverse SONET collector ring. Some of the fiber fed cell sites also support licensed microwave extensions to pick up additional end cell sites. The collector ring connects back to a core aggregation ring. In the core aggregation ring individual circuits or packets are mapped onto TTM's underlying SONET transport network which provides fully redundant and physically diverse delivery of the traffic to wireless carriers' switches. The TTM network is designed to withstand fiber cuts on the Sonet rings in the network, as well as the loss of an entire aggregation node site in larger markets.
When employing licensed microwave systems, TTM typically operates in the 6, 11, 18 or 23 GHz bands, with small antennae (typically 1 to 2 ft. diameter). We engineer protected, n x 155 Mbps capable systems according to the applicable Crane Rain Table distances that support our Service Levels in each market.
