Bibliography Abstract
Describes the requirements for the optical transport module of order n (OTM-n) signals of the optical transport network, in terms of: - optical transport hierarchy (OTH); - functionality of the overhead in support of multi-wavelength optical networks; - frame structures; - bit rates; - formats for mapping client signals.
