9.2 Synchronization
9.2.1 Definition:
Synchronization is the function which keeps all digital equipment in a communications network operating at
the same average frequency. With respect to digital transmission, information is coded into discrete pulses.
When these pulses are transmitted through a digital communications network, all synchronous Network
Elements are traceable to a stable and accurate timing source. Network synchronization is accomplished
by timing all synchronous Network Elements in the network to a stratum 1 source so that transmission from
these network points have the same average line rate.
9.2.2 Technical Requirements
10.0 Pricing
SBC TEXAS will provide synchronization to equipment that is owned by SBC TEXAS and is used to provide
a network element to CLEC in the same manner that SBC TEXAS provides synchronization to itself.
