Upgrade a Single Span of OC-48 ring to OC-192
A single span of an existing OC-48 UPSR ring can be upgraded to OC-192 using the transparent DCC
capabilities. Refer to Figure 3-64. The OC-192 side of the span can be unprotected, 1+1 or UPSR. Once in
place, the upgraded span can be used to carry additional traffic point-to-point between the two locations on
the span.
