3.1.4 Unprotected UPSR
The unprotected UPSR configurations of the TE-2020 system are discussed in section 3.4 “UPSR (Unidi-
rectional Path-Switched Rings)” on page 19.
3.2 1+1 Terminal
The TE-2020 Main Shelf can be used at each end of a 1+1 terminal span terminating a single unprotected,
or two 1+1 protected, optical interfaces (OC-3, OC-12, OC-48, or OC-192). The TE-2020 system may be
provisioned to connect any incoming STS or VT1.5 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. A simple 2-
node terminal configuration is shown in Figure 3-8. A single TE-2020 Main Shelf can be used as a single
terminal.
