Note: At JungleMUX nodes where Ethernet add/drop is not required, ETHER-
1000 units are not equipped while the STS-1 SPEs used for Ethernet traffic are
passed through.
Bandwidth Partitioning
The SONET bandwidth accessed by ETHER-1000 unit can range from 50 Mb/s
(1 x STS-1 SPE) to 1.2 Gb/s (24 x STS-1 SPE). The unit can partition this
bandwidth into as many as four TDM pipes. Each provisioned TDM pipe can use
from 50 Mb/s to 1.2 Gb/s of bandwidth, to a maximum total of 1.2 Gb/s for all
provisioned TDM pipes (Figure 5). The ETHER-1000 unit has independent traffic
forwarding queues for each TDM pipe, which ensures that traffic carried in
different TDM pipes will be independently queued within the "WAN" switch. This
feature allows for establishing "guaranteed SONET bandwidth" for selected
critical VLANs when multiple VLANs are handled by the same ETHER-1000
system.
