BITS is a North American term that describes a building-centric timing system. Also referred to as a Synchronization Supply Unit (SSU), the BITS system efficiently manages the number of timing interfaces within a structure.

Without something such as BITS/SSU in place, it is possible to have many different timing sources within the same building because of the number of synchronous links that the building might contain. BITS operates by providing common Stratum 1 ingress and egress external timing connections to the building (typically deployed over a T1 or E1), and then distributing timing internally to all circuits that require it.

At Empowered, we specialize in understanding complex in-building network timing requirements and the implementation and integration of unique BITS solutions.
