Modular
Fibre Optic Multiplexer for parallel
Voice and Data Applications over one
155 Mbps Line.
C-MUX-155 is a compact
Integrated Access Device (IAD) designed
to connect SONET/SDH networks and
LAN environments. The C-MUX-155 combines
TDM traffic (E1/DS1/DS3) and Ethernet
data utilising flexible Virtual Concatenation
over the OC-3/STM-1 frame structure.
The C-MUX-155provides a compact and
cost-effective solution via a powerful
Layer-2 Ethernet
interface and changeable TDM interfaces.
The ability to migrate into complex
networks and services is provided
by
an optional
full-Featured ADM module. The Layer-2
Ethernet card consists of 8 external
LAN interfaces and up to 8 virtual
WAN interfaces. One LAN interface
supports 1GBaseT and the remaining
seven interfaces
support 10/100BaseT with auto-negotiation.
Each Ethernet stream – LAN Port,
VLAN or a combination – is encapsulated
(GFP-F or LAPS) and mapped into High-order
or Low-order VCs/VTs using Virtual
Concatenation. In each Ethernet stream,
Bandwidth can
be allocated, insteps of 1Mbps, into
the SONET/SDH transport channel. The
bandwidth of each channel can be configured
individually in steps of VT-1.5 in
SONET networks, or in steps of VC-12
in SDH
networks. |
