e3
Syntax [no] e3 [sonet-sdh-index]
Context config>port>tdm
Description This command enables the context to configure E3 parameters on a 4-port DS3/E3 Adapter
card. E3 lines provide a speed of 34.368 Mb/s and are frequently used by service providers
outside North America.
Default n/a
Parameters sonet-sdh-index — specifies the components making up the specified SONET/SDH path
