The most accurate and stable clock source within a physical structure. All
digital equipment in the structure receives timing reference from the same
master clock. BITS derives its signal from a stratum-3E or better reference
signal. BITS provides network clock synchronization through external timing
to the Nortel Multiservice Switch 7400, Multiservice Switch 15000, or
Multiservice Switch 20000 node.
