The VSC9115 is a 2.5 Gb/s multi-service SONET/SDH data mapping device that supports both contiguously concatenated and virtually concatenated transport channels.
The AU-3/TU-3/VC-3, STS-1/VC-3, and STS-3c/VC-4 transport channels may be virtually concatenated to support larger custom transport channels. Up to 48 packet streams can be mapped into these transport channels (up to 16 for STS-3c/VC-4).
Virtual concatenation of AU-3/TU-3/VC-3, STS-1/VC-3, or STS-3c/VC-4 transport channels into Virtual Groups is supported through SONET/SDH. Path Overhead H4 byte is processed for payload identifiers, types, and sequencing. Non-contiguous transport channels can be tagged and linked through these overhead bytes to form larger, custom
transport channels.
(LCAS) protocol is supported by processing the H4 byte control packets and reporting back member status.
Flexible Payload Processing for (GFP) is supported for several interfacing formats including Ethernet Frames. It also supports HDLC-like framing: PoS - RFC2615, LAPS - X.85, and X.86
