4G/5G Layer 2 Connect is orderable as layer 2 (Ethernet Bridged) or a layer 3(IP routed) services. The solution supports multiple Mobile Carriers, NBN TC4 and Internetconnection (such as wifi and Mobile “Hotspots”) giving customers the flexibility to select the data service best suited to their needs.
4G/5G Layer 2 Connect is supplied with managed NTU with Mobile SIM, NBN NBES or WiFi client allowing simple and flexible deployments.
L2i (Layer 2 interconnect solution) implemented as a standalone service which can either be used as a primary or as a standalone backup service.
The customer network is connected to the Accessport NTU and Ethernet traffic is encapsulated and transparenly transmitted to the L2i core interconnect. Traffic received on the L2i core interconnect is transparently transmitted to the customer NTU.
Layer 3 backup implementation where the AccessPort NTU is connected to the customer CPE. In this situation the AccessPort is configured to operate with VRRP.
The wireline link is defined as the primary access and the AccessPort as the secondary path. The path selection is negotiated between the NTU and the AccessPort using layer 2 VRRP which allows transparent support of static and dynamic IP networking.
In the event of a fixed line failure the, NTU will signal to the NTU it has lost connectivity and the AccessPort will establish a secure 4G connection to the network core using point to point IPSEC and GRE packet encapsulation. The mobile service link is usually active within 60 seconds and will disconnect automatically when the primary link is re-established.
