Interface Cards

for the Cisco

SONET/SDH MSPP

The Cisco ONS 15454 Ethernet solution consists of two interface cards, E100T and E1000-2, which can be installed

in any of the ONS 15454 shelf assembly’s 12 multiservice interface slots. The E100T-12 integrates an IEEE.802.1D

Layer 2 switch with 12 autosensing 10BASET/100BASET RJ-45 copper interfaces. The E1000-2 integrates an

IEEE.802.1D Layer 2 switch with two modular gigabit interface converter (GBIC) interface slots. Each GBIC slot can

be populated with either 1000BASESX (short reach over multimode fiber at 850 nm) or 1000BASELX (long reach

over single-mode fiber at 1310 nm) optics.

The Cisco ONS 15454 Ethernet solutions are extremely powerful as a result of the incorporation of Layer 2 switching

within the optical transport system. They enable users to build point-to-point or shared-packet ring circuits. Most

traditional transport devices map Ethernet frames directly over dedicated time-division multiplexing (TDM)

bandwidth on a Synchronous Optical Network (SONET) or Sychronous Digital Hierarchy (SDH) transport network.

This solution creates multiple physical, point-to-point circuits, which are severely underutilized as a result of the

bursty nature of Ethernet traffic. This results in a transport network that is larger than the actual data traffic demands.
