The eDMR Backhaul service is an Ethernet bitstream service that provides a single modified EPL Ethernet Virtual Circuit (EVC) with up to three service VLANs as follows:
- At the E-NNI located at the mobile site each service VLAN is terminated as either:(i) an 802.1ad SVID per service VLAN; or an 802.1ad SVID per service VLAN; or 802.1q. Only available for single service VLAN option.
- At the eDMR Ethernet Handover Connection at the designated handover point each service VLAN is terminated as either: an 802.1ad SVID per service VLAN at the E-NNI; or 802.1q at the E-NNI. Only available for single service VLAN option
- Each service VLAN allows up to 4093 customer VLANs to be passed transparently between the mobile site and the mobile service provider, delivered over an eDMR access.
- All service VLANs share a common bandwidth profile applied to the EPL; see appendix A. Traffic that exceeds the bandwidth profile will be discarded as out-of-profile:
- Support for high priority classified traffic only.
- A range of symmetrical bandwidth options selected on a per-site basis.
- Supports tagged traffic only at the E-NNI at the mobile site and eDMR handover connection.
- The designated handover location will be the closest First Data Switch (FDS) location to the eDMR node based on deployed eDMR and fibre routes.
