Extensive Performance Monitoring Features
BENEFITS:
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 VSC9118 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.
APPLICATIONS:
Point-to-Point Linear Configurations Such as a Multi-Service Router/
Switch or Point-to-Point Transport
SONET/SDH ADM and TSI Switching Systems
Gigabit Ethernet Transport Applications Utilizing LAPS or GFP Frame
Encapsulations
Point-to-point Packet-Over-SONET (PoS) Router Applications
Data Channels or Payloads can be Shared Among up to 192 Transport
Channels by Using Contiguous Concatenation and/or Virtual Concatenation
STANDARDS:
ANSI T1.105, Telcordia GR-253-CORE, and ITU-T G.707 Compliant
HDLC-Like Framing: PoS - RFC2615, LAPS - X.85, and X.86
