Object

dB Unsigned32
Desired EFMCu port SNR margin to be achieved on all PMEs
assigned to the port, during initialization. (The SNR margin
is the difference between the desired SNR and the actual SNR).
Note that 802.3ah recommends using a default target SNR margin
of 5 dB for 2BASE-TL ports and 6 dB for 10PASS-TS ports in
order to achieve a mean Bit Error Rate (BER) of 10^-7 at the
PMA service interface.
This object is read-write for the -O subtype EFMCu ports
(2BaseTL-O/10PassTS-O) and not available for the -R subtypes.
Changing of the target SNR margin MUST be performed when the
link is Down. Attempts to change this object MUST be rejected
(in case of SNMP with the error inconsistentValue), if the
link is Up or Initializing.
Note that the current SNR margin of the PMEs comprising the
EFMCu port is represented by efmCuPmeSnrMgn.
This object MUST be maintained in a persistent manner.
