Table 7 Mef-Defined Ethernet Service Types - Cambium Networks PTP 820G Technical Description

Chapter 5: Feature Description
If the service frame does not comply with the CIR defined in the bandwidth profile, but does comply with the
EIR and EBS, it is marked Yellow. In this case, the average service frame rate is greater than the CIR but less than
the EIR, and the maximum service frame size is less than the EBS.
If the service frame fails to comply with both the CIR and the EIR defined in the bandwidth profile, it is marked Red
and discarded.
In the PTP 820G, bandwidth profiles are constructed using a full standardized TrTCM policer mechanism.
Ethernet Services Definitions
The MEF provides a model for defining Ethernet services. The purpose of the MEF model is to help subscribers
better understand the variations among different types of Ethernet services. PTP 820G supports a variety of
service types defined by the MEF. All of these service types share some common attributes, but there are also
differences as explained below.
Ethernet service types are generic constructs used to create a broad range of services. Each Ethernet service
type has a set of Ethernet service attributes that define the characteristics of the service. These Ethernet service
attributes in turn are associated with a set of parameters that provide various options for the various service
attributes.
Figure 30 MEF Ethernet Services Definition Framework
The MEF defines three generic Ethernet service type constructs, including their associated service attributes and
parameters: Ethernet Line (E‐Line)
Ethernet LAN (E‐LAN)
•
Ethernet Tree (E‐Tree)

Multiple Ethernet services are defined for each of the three generic Ethernet service types. These services are
differentiated by the method for service identification used at the UNIs. Services using
All‐to‐One Bundling UNIs (port‐based) are referred to as "Private" services, while services using Service
Multiplexed (VLAN‐based) UNIs are referred to as "Virtual Private" services. This relationship is shown in the
following table.
