Chapter 17 CE-100T-8 Ethernet Operation
CE-100T-8 SONET Circuits and Features
A single circuit provides a maximum of 100 Mbps of throughput, even when an STS-3c 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. Table 17-3 shows the minimum
SONET circuit sizes required for 10 Mbps and 100 Mbps wire speed service.
*STS-1-2v provides a total transport capacity of 98 Mbps.
The number of available circuits and total combined bandwidth for the CE-100T-8 depends on the
combination of circuit sizes configured. Table 17-5 shows the circuit size combinations available for
CE-100T-8 CCAT high-order circuits on the ONS 15310-CL and ONS 15310-MA. Table 17-6 shows the
circuit size combinations available for CE-100T-8 VCAT high-order circuits on the ONS 15310-CL and
ONS 15310-MA.
The CE-100T-8 supports up to eight low order VCAT circuits. The available circuit sizes are VT1.5-nv,
where n ranges from 1 to 64. The total number of VT members cannot exceed 168 VT1.5s with each of
the two pools on the card supporting 84 VT1.5s. The user can create a maximum of two circuits at the
largest low order VCAT circuit size, VT1.5-64v.
