Figure 3-18 UPSR Ring Operation
Figure 3-19 shows a typical TE-2020 shelf for an OC-192 UPSR. This architecture will take advantage of
the TE-2020 capability to transmit and receive identical high-speed data in both directions. When config-
ured as a UPSR node, the incoming signal is duplicated, and then transmitted around both ring directions.
The receiving NE facility makes the signal selection by determining the best signal received between the
two optical cards. Note that the OC-192 x1 PLMs are mounted in separate slots for equipment protection.
The TE-2020 system may be provisioned to connect any incoming STS to any outgoing tributary port
regardless of PLM line rate or physical location, assuming the payload does not exceed the line rate of the
interface.
The system transport capacity for a TE-2020 ADM shelf in a UPSR ring configuration is up to 192 total
STS-1s from any or a combination of the tributaries. The Tributary Shelves can each support a combined
192 protected STS-1s worth of bandwidth that can be used for transport, hairpinning, and partially filled
