Carrier Line Service (CLS) is our managed Layer 1 service for dedicated and high quality point-to-point data transmissions, supporting scalable high-capacity bandwidths up to 100 Gbit/s and reliable connectivity based on our Swisscom Optical Network for All-IP Transport Services (SONATE).
CLS is available with Basic and Premium Service Level Agreements (SLAs), whereby the Premium SLA offers two options, depending on guaranteed annual end-to-end service availability and time-to-repair.
The Basic service quality provides fast, safe and stable data transmissions and a high level of line availability with typical annual end-to-end service availability of 99.90%.
With CLS Premium, telecom service providers benefit from a guaranteed annual end-to-end service availability from 99.95% to 99.99%, depending on the chosen SLA (Premium Silver or Premium Platinum). Proactive service monitoring, round the clock troubleshooting are guaranteed with all Premium services. In addition, Premium Platinum SLA provides a highly-redundant dual-homed end-to-end connectivity with no single point of failure.
