Platform Considerations

You can configure unchannelized SONET/SDH interfaces on the following E-series routers:

This section describes the line modules and I/O modules that support SONET/SDH interfaces.

For detailed information about the modules that support SONET/SDH interfaces on ERX-14xx models, ERX-7xx models, and the ERX-310 router:

See ERX Module Guide, Table 1, Module Combinations for detailed module specifications.
See ERX Module Guide, Appendix A, Module Protocol Support for information about the protocols and applications that SONET/SDH modules support.

For detailed information about the modules that support SONET/SDH interfaces on the E120 router and the E320 router:

See E120 and E320 Module Guide, Table 1, Modules and IOAs for detailed module specifications.
See E120 and E320 Module Guide, Appendix A, IOA Protocol Support for information about the protocols and applications that SONET/SDH modules support.
