CAUTION: An interface is disabled when being shut down. So, perform
operations of this type with caution.
You can verify the configuration of a CE3 interface by using the display
commands listed in the following table in any view.
Use the command...
controller e3
interface-number
bert pattern { 2^7 | 2^11 |
2^15 | qrss } time number
[ unframed ]
e1 line-number bert pattern
{ 2^11 | 2^15 | 2^20 | 2^23 |
qrss } time number
[ unframed ]
For the CE3 clock { master | slave }
interface
For an E1 line e1 line-number set clock
{ master | slave }
national-bit { 0 | 1 }
crc { 16 | 32 | none}
For the CE3 loopback { local | payload |
interface remote }
For an E1 line e1 line-number set loopback
{ local | payload | remote }
