Platform Considerations

You can configure unchannelized T3 and unchannelized E3 interfaces on the following E-series routers:

ERX-1440 router
ERX-1410 router
ERX-710 router
ERX-705 router
ERX-310 router

Note: The E120 router and the E320 router do not support configuration of unchannelized T3/E3 interfaces.

For detailed information about the modules that support unchannelized T3/E3 interfaces on ERX-7xx models, ERX-14xx 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 unchannelized T3/E3 modules support.
