frame-format
Syntax In ATM E1 interface view:
frame-format { crc4-adm | no-crc4-adm }
In ATM T1 interface view:
frame-format { esf-adm | sf-adm }
undo frame-format
View ATM E1/T1 interface view
Parameter crc4-adm: Sets the ATM over E1 framing format to 4-bit cyclic redundancy check
ATM direct mapping (CRC4 ADM).
no-crc4-adm: Sets the ATM over E1 framing format to no-CRC4 ADM.
esf-adm: Sets the ATM over T1 framing format to extended super frame ADM
(ESF ADM).
sf-adm: Sets the ATM over T1 framing format to super frame ADM (SF ADM).
Description Use the frame-format command to configure the ATM over E1/T1 framing
format.
