Figure 10: SDH Multiplexing
For both SONET/SDH VT configurations, you must identify the path and controllers above
the path layer. Table 11 on page 111 shows the identifiers for these configurations, and
Table 12 on page 111 provides definitions for the identifiers.
Table 11: Identifiers for SONET/SDH VT Controllers
Example Identifier Configuration
