Telecom Interconnect

Private interconnect is how a group connects many branch sites securely. The hub sits at headquarters and the branches connect to it in a star topology over the carrier existing fiber footprint, so no site needs a direct link to any other site.

Where there are many sites, interconnect is cheaper than a mesh of point-to-point circuits, and because traffic stays inside the carrier private network it is both faster and more secure than connecting branches over the public internet.

China Telecom point-to-point circuits are digital circuits carried directly on the transmission network, built on SDH or MSTP. MSTP adds finer granularity and standard ethernet interfaces, which makes it easier to hand over to enterprise equipment. Digital circuits are the standard way to build a high-speed, fully transparent private network.

In southern China, China Telecom has the widest fiber footprint and the most stable transmission, which makes it the safest default for a multi-site design. It is also the most expensive of the three carriers for point-to-point circuits, so the design should be reviewed against the actual sites.
