buffer
A linked list of blocks. The blocks that make up a buffer are not necessarily
contiguous. Buffers are composed of multiple blocks when the user data does
not fit into a single block. The linkage of blocks to form a buffer is managed by
the queue controller.
buffer memory
See
building-integrated timing supply (BITS)
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.
