Link type

Link Type

There are two types of links:

  • service-transparent (ST) link is a link providing transparent bit transmission,

  • service-aware (SA) link is a link in which interfaces on both ends will handle the payload according to protocol format and/or data bit rate before transmitting and afterreceiving
