Chapter 24 CE-100T-8 Ethernet Operation

CE-100T-8 SONET/SDH Circuits and Features

The CE-100T-8 has eight POS ports, numbered one through eight, which can be managed with CTC or
TL1. Each POS port is statically mapped to a matching Ethernet port. By clicking the card-level
Provisioning > POS Ports tab, the user can configure the Administrative State, Framing Type, and
Encapsulation Type. By clicking the card-level Performance > POS Ports tab, the user can view the
statistics, utilization, and history for the POS ports.

Available Circuit Sizes and Combinations

Each POS port terminates an independent contiguous concatenation (CCAT) or virtual concatenation
(VCAT) circuit. The SONET/SDH circuit is created for these ports through CTC or TL1 in the same
manner as a SONET/SDH circuit for a non-Ethernet line card.

A single circuit provides a maximum of 100 Mbps of throughput, even when a larger STS-3c or VC-4
circuit, which has a bandwidth equivalent of 155 Mbps, is provisioned. This is due to the hardware
restriction of the Fast Ethernet port. A VCAT circuit is also restricted in this manner.
