EFM (Ethernet in the first Mile) interfaces provide high speed, symmetrical Ethernet services over SHDSL links between the system and network extender EFM modems and Ethernet access devices like EtherXtend and N2N CPE devices.

Profile
Port |
The port assigned to this interface. |
PAF Admin State |
Administrative (desired) state of the PME Aggregation Function (PAF) of the EFMCu port. Values: Disabled: PME Aggregation will not be performed by the device. Enabled: PME Aggregation will be performed by the device. |
PAF Discovery Code |
A unique Discovery Code for this device. |
Admin Profile |
Admin profile for all PMEs in the EFMCu port. |
Target Data Rate(kB/s) |
Desired EFMCu port 'net' (as seen across MII) Data Rate in Kbps, to be achieved during initialization, under spectral restrictions placed on each PME via Admin Profile, with the desired SNR Margin specified by Worst Case SNR-Margin and Current Condition SNR-Margin depending on the values of Worst Case Mode and Current Condition Mode. In case of PAF, this object represents a sum of individual PME data rates, modified to compensate for fragmentation and 64/65B framing overhead (e.g. target data rate of 10Mbps shall allow lossless transmission of full-duplex 10Mbps Ethernet frame stream with minimal inter-frame gap). The value is limited above by 100Mbps as this is the max burst rate across MII for EFMCu ports. The value between 1 and 100000 indicates that the total data rate (ifSpeed) of the EFMCu port after initialization should be equal to the target data rate or less, if the target data rate cannot be achieved under spectral restrictions specified by Admin Profile and with desired SNR margin. In case the copper environment allows to achieve higher total data rate than specified by the target, the excess capability SHALL be converted to additional SNR margin and spread evenly across all active PMEs assigned to the (PCS) port. The value of 999999 means that the target data rate is not fixed and should be set to the maximum attainable rate during initialization (Best Effort), under specified spectral restrictions and with desired SNR Margin. Changing of the Target Data Rate MUST be performed when the link is Down. |
Worst Case SNR Margin (dB)
|
Desired EFM port SNR Margin to be achieved on all PMEs assigned to the port, during initializiation if Worst Case Mode is TRUE. (The SNR margin is the difference between the desired SNR and the actual SNR). |
Low Bandwidth Alarm Threshold(kB/s) |
Specifies the EFMCu port Low Bandwidth alarm threshold. When the data speed for this port reaches or drops below this threshold, a Low Bandwidth notification willl be generated if Low Bandwidth Notify is set to enabled. A value of 0 means no Low Bandwidth notification will be generated. |
Low Bandwidth Notify |
Indicates whether a Low Bandwidth alarm should be generated for this interface. Values Enabled Disabled |
Current Condition Mode |
Whether the SNR monitoring is set for current conditions. Values: True False |
Current Condition SNR Margin (dB)
|
Desired EFM port SNR Margin to be achieved on all PMEs assigned to the port, during initializiation if Current Condition Mode is True. (The SNR margin is the difference between the desired SNR and the actual SNR). |
Worst Case Mode |
Whether the SNR monitoring is set for worst case conditions. Values: True False |
PAF Auto Discovery |
Determines how EFM bond groups and their members are created. This setting must be the same for all ports destined to the same bond group. disabled: EFM bond groups and the members must be manually provisioned. optional: EFM bond groups and members may be manually or automatically provisioned. If the links were manually added to a bond group, this configuration is used and EFM Discovery is not performed. If the links were not manually added to a bond group and the CPE supports EFM Discovery, provisioning will be automatic. When the parameter is set to optional and the CPE is not discovery capable, a dynamic bond group will not be created, but the link will remain. If the CPE is discovery capable, a dynamic bond group is created with the port as a member of the bond group. If the port already belongs to a bond group, the bond group type will be checked. If the bond group type is dynamic, the discovery messages are sent to verify that the ports are still connected to the same CPE. If the bond group type was created from the CLI or with EMS, (25-99 or 101-199), discovery messages are not sent and the current configuration of bond groups remain as they are. required: EFM bond groups and members are automatically provisioned with the EFM Discovery algorithm. If the CPE device does not support EFM Discovery, the link will not be obtained. When the parameter is set to required, the CPE must be discovery capable or the links will fail. When required is set, discovery automatically creates bond groups depending on the number of CPE ports connected to the EFM SHDSL card. Default: optional |
