NOTE
In the IPRAN macro base station backhaul network solution, ATN 905 is supported in the following modes:
l
Native IP mode: If IPRAN uses a Layer 3 solution, such as, the hierarchy VPN (HVPN) solution, it is
recommended that ATN 905 connect to the IPRAN macro base station backhaul network in Native IP
mode, which facilitates deployment of end to end (E2E) Layer 3 IP connectivity and performance check
schemes.
l
Native ETH: If IPRAN uses E2E Layer 2 solution or L2+L3 mixed VPN, it is recommended that ATN
905 connect to the IPRAN macro base station backhaul network in Native ETH mode, which facilitates
transparent transmission and processing of E2E Layer 2 VLAN packets.
Carrying Enterprise Leased Line Services
Generally, customer premises equipment (CPE) that bears enterprise leased line services
connects to a provider edge (PE) through optical fibers or a leased third-part network as shown
in
.
Figure 1-2
CPE directly connecting to a carrier network
A CPE is often far away from a PE. If a fault occurs, it is difficult to locate whether the fault
occurs on the optical fiber, leased network, enterprise network, or carrier network.
