ATN 905 can be deployed as an Ethernet demarcation device (EDD) directly connected to CPE
and sharing the same equipment room with the CPE as shown in Figure 1-3. In this way, the
carrier network extends to the client side and the provider can manage the network between the
EDD and the PE.

In the Huawei enterprise service bearer solution, ATN 905 functioning as an EDD has the
following advantages:
l Supports IP forward performance monitoring (FPM), tests without requiring meters at sites,
quality of service (QoS), and quick fault sectionalization and location complying with RFC
2544.
– Supports 802.1Q in 802.1Q (QinQ) for separating user VLANs and carrier VLANs,
facilitating fault sectionalization.
– Supports dying gasp so that equipment reports an alarm when experiencing power
outage.
l Support real-time performance management through periodical tests and statistics on E2E
service performance including the throughput, delay, and packet loss rate, service level
agreement (SLA) compliance reports.
Figure 1-4 and Figure 1-5 show basic networking of the enterprise service bearer solution to
which ATN 905 belongs.
l With the help of the current IPRAN, ATN 905 can connect to the IPRAN macro base station
backhaul network. On the E2E ATN+CX network, enhanced ATN functions, such as DCN
plug and play and RFC 2544-compliant IP FPM, can be deployed to improve the network
operation and maintenance efficiency.
NOTE
In the IPRAN macro base station backhaul network solution, ATN 905 can also connect to the macro
base station backhaul network in Native IP or Native ETH mode.
