switching, and classification. The Ethernet frames are then passed to the Ethermap where Ethernet traffic
is terminated and is encapsulated using HDLC or GFP framing on a per port basis. The encapsulated
Ethernet frames are then mapped into a configurable number of virtual concatenated low and high order
payloads, such as VT1.5 synchronous payload envelope (SPE), STS-1 SPE, or a contiguous
concatenated payload such as STS-3c SPE. Up to 64 VT1.5 SPEs or 3 STS-1 SPEs can be virtually
concatenated. The SONET SPE carrying encapsulated Ethernet frames are passed onto the qMDM
FPGA, where four STS-3 frames are multiplexed to form a STS-12 frame for transport over the SONET
network by means of the Bridging Convergence Transmission (BTC) ASIC.
In the Egress direction (SONET-to-Ethernet), the FPGA extracts four STS-3 SPEs from the STS-12
frame it receives from the BTC and sends each of the STS-3s to the ET3 mappers. The STS-3 SONET
SPE carrying GFP or PPP/HDLC encapsulated Ethernet frames is then extracted and buffered in
Ethermap's external memory. This memory is used for providing alignment and differential delay
compensation for the received low-order and high-order virtual concatenated payloads. After alignment
and delay compensation have been done, the Ethernet frames are decapsulated with one of the framing
protocols (GFP or HDLC). Decapsulated Ethernet frames are then passed onto the network processor for
QoS queuing and traffic scheduling. The network processor switches the frame to one of the
corresponding PHY channels and then to the Ethernet port for transmission to the external client(s).

Ethernet Card Software Feature and Configuration Guide for the Cisco ONS 15454, Cisco ONS 15454,

5.11.1 CE-100T-8 Card-Level Indicators

The CE-100T-8 card faceplate has two card-level LED indicators, described in
Table 5-21
Card-Level LEDs
SF LED (Red)
ACT LED (Green)
5.11.2 CE-100T-8 Port-Level Indicators
The CE-100T-8 card has two LEDs embedded into each of the eight Ethernet port RJ-45 connectors. The
LEDs are described in
OL-9217-01
CE-100T-8 Card-Level Indicators
Description
The red FAIL LED indicates that the card processor is not ready or that a
catastrophic software failure occurred on the CE-100T-8 card. As part of the
boot sequence, the FAIL LED is turned on until the software deems the card
operational.
The green ACT LED provides the operational status of the CE-100T-8. When
the ACT LED is green, it indicates that the CE-100T-8 card is active and the
software is operational.
