Gigabit Ethernet Drop and Continue

OPTera Metro 3500 Release 12.1, extends its Unidirectional Multi-Node Drop and Continue capability to support unidirectional Gigabit Ethernet (GE) traffic. Unidirectional Multi-Node Drop and Continue provides the ability to drop a time slot, either SONET contiguous (STS-1, STS-3c, STS-12c and STS24c) or Virtual concatenation (STS-1-nv, n = 1 through 21 or STS-3c-nv, n = 1 through 7), at a single or on a continuing series of nodes in an UPSR ring or linear chain using a single timeslot on the ring or the linear chain. Gigabit Ethernet unidirectional drop and continue connections are supported by the 2xGigE/FC-P2P interface for UPSR rings. Figure 2-1 on page 2-4, illustrates an application where a video signal is inserted on a 2xGigE/FC-P2P interface at one node and dropped on 2xGigE/FC-P2P interfaces at 5 subsequent nodes using a unidirectional CCAT or VCAT timeslot(s).
