Q: What are the maximum number of ports in MA5800 series subrack?

A:

Q: What is the great improvement of MA5800?

A: Great improvement:

• Symmetric 10G GPON (XGS PON): Supports XGS PON , Improves the upstream bandwidth from 2.5G to 10G and enhances symmetric service supporting.

• ONT energy saving: Supports the ONT sleep mode. Reduces ONU power consumption for environmental protection.

• 8 times MAC address and ARP table than MA5680T and MA5683T.

Q: Does MA5800 have new typical New Hardware Board?

A: Yes, H901TWED, 8-port symmetric 10G GPON interface board, it works together with the optical network terminal (ONT) to provide 10G GPON access services.

Q: How to configure Ring Check of the MA5800?

A: The Ring Check feature enables the device to send the Ring Check packets periodically and monitors the Ring Check packets received on the user-side, cascade-side, and network-side to detect whether a loop occurs on the network of the carrier. If a loop occurs, the MA5800 deactivates the subscriber port on the loop and reports the corresponding alarm to the NMS. This ensures that the device runs in the normal state and that legal users are not affected.

• Run the ring check enable command to enable the user-side ring network detection.

• Run the ring check uplink detection enable command to enable the network-side ring network detection.

• Run the ring check cascade detection enable command to enable the cascade-side ring network detection.

Q: Why switchover occurs between the active and standby boards?

A: Possible Causes:

• The active/standby switchover command is manually executed.

• The original active control board is faulty.

• The physical port or line on the original active control board is faulty.

• The active control board is faulty, causing a protective switchover of the system.

• The clock daughter board of the original control board is faulty.

• The system performs a periodical switchover.

Q: How many 10 GE ports on MA5800?

A: 8 x 10 GE SFP+ interface or 8 x GE SFP/eSFP interface.

Q: Can MA5800 support 4K video?

A: Each sub-rack supports up to 32K users with 100 Mbit/s of non-blocking bandwidth, letting everyone enjoy seamless 4K video.

Q: Does MA5800 support the Multicast?

A: Yes, it supports Layer 3 multicast networking, also supports IPv4 PIM SSM.

• Protocol Independent Multicast-Source-Specific Multicast (PIM-SSM) enables a user host to rapidly join a multicast group if the user knows a multicast source address. PIM-SSM sets up a shortest path tree (SPT) from a multicast source to a multicast group, while PIM-SM uses rendezvous points (RPs) to set rendezvous point trees (RPTs). Therefore, PIM-SSM implements a more rapid join function than PIM-SM.

• Different from the any-source multicast (ASM) model, the SSM model does not need to maintain an RP, construct an RPT, or register a multicast source.

• The SSM model is based on PIM-SM and IGMPv3. The procedure for setting up a multicast forwarding tree on a PIM-SSM network is similar to the procedure for setting up an SPT on a PIM-SM network. The receiver's DR, which knows the multicast source address, sends Join messages directly to the source so that multicast data streams can be sent to the receiver's designated router (DR).

Q: Does MA5800 support the VPLS?

A: The Virtual Private LAN Service (VPLS), also called the Transparent LAN Service (TLS) or virtual private switched network service, is a Layer 2 VPN (L2VPN) technology that is based on Multi-Protocol Label Switching (MPLS) and Ethernet technologies.
