Figure 10: SDH Multiplexing
For both SONET/SDH VT configurations, you must identify the path and controllers
above the path layer. Table 12 on page 115 shows the identifiers for these
configurations, and Table 13 on page 115 provides definitions for the identifiers.
Table 12: Identifiers for SONET/SDH VT Controllers
Example Identifier Configuration
10/1/2/2/1 pathChannel/pathPayload/tributaryGroup/tributaryNumber/channelNumber Unframed E1
NOTE: The router automatically assigns the channel number one to an unframed E1 line.
10/1/2/2/1 pathChannel/pathPayload/tributaryGroup/tributaryNumber/channelGroup Fractional T1
or E1
