OPTera Metro 3500 Multiservice Platform NTRN10AN Rel 12.1 Standard Iss 1 Apr 2004
OPTera Metro 3500 supports bandwidth management capabilities that include
time slot assignment (TSA), time slot interchange (TSI), hairpinning,
broadcast, drop-and-continue, path protection, unidirectional services,
connection editing, and in-service rollover. This bandwidth management
capability is available at VT1.5, STS-1, STS-3c, STS-12c, STS-24c and
STS-48c levels.
