ETHERNET OVER SELF-HEALING NETWORK  

Keep Your Business Up and Running with SHNS

Point-to-point service that connects two customer or wire center locations.

Who can blame you for wanting to avoid downtime at all costs? Fortunately, CenturyLink offers a solution that allows you to minimize this pesky part of doing business without breaking the bank. Ethernet over Self-Healing Network Services (SHNS) provides business continuation, disaster recovery, and survivability through a failure-resistant telecommunications network. The service is designed to automatically detect service degradation or a single failure anywhere within the system. It then reconfigures itself around the point of failure to ensure a near-continuous flow of information between those locations that are within the survivable network.

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 provides your network the highest level of survivability available today.
