PRIVATE LINE SYNCHRONOUS SERVICE TRANSPORT  

The Next Step in the Evolution of Voice, Data and Video Transport

Ensure high-capacity transport for your changing business needs with SST.
Are your voice, data, and video transport needs outgrowing the capacity of your existing DS-1 or DS-3 lines? Synchronous Service Transport (SST) is a two-point broadband, shared Private Line solution that provides you with a reliable high-capacity connection for the transfer of large volumes of traffic. SST can help grow your business by offering economies of scale, scalability and interoperability.

HOW IT WORKS 
——
SST is a point-to-point service that connects two customer or wire center locations. You can also tie together more locations by cross-connecting SST systems or connecting with other services. Should your network sustain a fiber cut, SST’s four-fiber configuration makes it possible for your network to remain functional. The service allows multiple circuit types, such as DS-1, DS-3, STS-1, OC-3, OC-3c (concatenated), OC-12, OC-12c, OC-48, OC-48c, 10 Mb Ethernet, 100 Mb Ethernet and 1 Gigabit Ethernet, to ride the SST separately or in combination, meeting your unique volume-transport needs. SONET technology ensures your network has the highest level of survivability available today.
