Figure 15-29 OSI/MSTP Scenario 3
OSI/MSTP Scenario 4 (Figure 15-30) shows the following:
• OSI is carried over an SDCC or RS-DCC termination.
• OSI has to be carried or tunneled to the other peer TXP/MXP through an OSC termination, GCC
termination, or both
• An OSS has IP connectivity to all the NEs through third-party NE network.
• The MSTP NE is a GNE for the third-party OSI-based SONET NEs. The MSTP NEs perform all
mediation functions.
• The third-party vendor NE is a GNE for the Cisco MSTP network.
