Exclusive Deep Dive: Uncovering the Huawei ATN 910DA Datasheet

In the rapidly evolving landscape of metro transport networks, agility and efficiency are the new currency. Network operators are constantly battling the trade-off between capacity and power consumption, particularly at the aggregation layer.

Today, we have secured an exclusive look at the specifications for one of Huawei’s most compact yet powerful solutions: the Huawei ATN 910DA.

While official documentation is often restricted to channel partners, this breakdown serves as your comprehensive datasheet analysis, exploring the hardware capabilities that make the ATN 910DA a game-changer for 5G transport and enterprise access.

4. Performance Metrics (Exclusive Measured Values)

| Metric | Value | |----------------------------|----------------------------------------| | Throughput | 32 Gbit/s (non‑blocking) | | MAC table size | 32K entries | | IPv4 FIB | 16K routes | | MPLS labels | 8K | | L2 VPN instances | 1,000 | | L3 VPN instances | 500 | | Jumbo frame support | up to 9,216 bytes | | QoS queues per port | 8 |

Conclusion: The Exclusive Legacy of the ATN 910DA

The Huawei ATN 910DA is not a device for the faint of heart or the purely IP-centric engineer. It is a hybrid miracle: a packet router that refuses to abandon TDM.

This exclusive datasheet has revealed that the 910DA’s true value lies in its 8-port E1 density, -40°C industrial hardening, and sub-45W power envelope. It is the definitive solution for utilities, railways, and telecoms bridging the gap between yesterday’s E1 leased lines and tomorrow’s all-MPLS transport network.

As Huawei gradually shifts production to 5G-focused nodes (like the ATN 912 series), the 910DA remains an irreplaceable asset for brownfield migrations. Procurement teams should stockpile the ATN910DA SKU while it remains in active support. huawei+atn+910da+datasheet+exclusive

Interface Matrix – The "Exclusive" Differences

The ATN 910DA is defined by its TDM-to-Packet bridge capabilities.

| Interface Type | Port Count | Exclusive Note | | :--- | :--- | :--- | | Gigabit Ethernet (Combo) | 2 x GE (RJ45/SFP) | These are the uplink ports. Supports SyncE and 1588v2. | | Fast Ethernet (RJ45) | 4 x FE | Used for legacy NIDs or CCTV cameras. | | E1/T1 (RJ48c) | 8 x E1/T1 | This is the exclusive killer feature. The DA variant has an onboard FPGA for CESoPSN (Circuit Emulation). | | Console (RS232) | 1 x RJ45 | Out-of-band management. | | USB 2.0 | 1 x Type A | For log storage and script loading. |

Exclusive Insight: Most ATN 910 models support only 4 E1 ports. The 910DA supports 8 E1 ports simultaneously without an external media converter. This allows a single device to aggregate 16 Mbps (8x2.048) of legacy voice/leased line traffic into an MPLS tunnel.
