2.4.4 Path Protection to Path Protection Connection Example

Ring 1 = Path Protection

Ring 2 =

Path Protection

This example, illustrated in Figure 2-30, uses an OC-3-4 card to feed Ring 2. Ring 1 can have any OC-N

trunk card, but the trunk card is most likely a single-port OC-48 or OC-12.

Note The STS calculation formula is: (((Port # -1)*Number of STS per port)+STS#).

STS 12/3/2 maps to STS-12-8 (((3-1)*3) +2).
