VCL-1400 STM-1/4/16/64 SDH Multiplexer with MPLS-TP
Valiant’s VCL-1400 STM-16/64 SDH Multiplexer with MPLS-TP is a compact POTP
platform which is targeted for deployment
in the edge and access part of a transport
network. It can be configured both as a TDM MSPP as well as a packet switch. It
supports both TDM and
Ethernet as line interfaces. It offers full redundancy and
comes with an expansion chassis for deployment in high-drop locations and can
be used
in point-to-point, linear, ring, T, and mesh networks.
