VSC9115
B E N E F I T S :
Allocated bandwidth for each data channel can be dynamically changed,
without interrupting the traffic, utilizing the Link Capacity Adjustment
Scheme (LCAS) to signal bandwidth changes to the receiving end. This
makes the VSC9115 well suited for carrying multiple varying data flows
from different customers with excellent bandwidth allocation granularity
and efficiency.
Available data channels or payloads can be shared among any number
of the possible maximum 48 transport channels by utilizing contiguous
concatenation and/or Virtual Concatenation at AU-4/TU-3/VC-3,
STS-1/VC-3, or STS-3c/VC-4 levels.

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
