Huawei MA5683T Platinum Line FAQ
Q: What is the difference between MA5683T and MA5603T?
A: MA5603T is multi service based while MA5683T is just OLT, MA5603T can support service like ADSL, VDSL, GPON etc, while MA5683T only supports GPON, P2P etc, but their hardware and configuration command is the same.

Q: What is the difference between MA5683T and MA5680T?
A: The only difference is capacity, MA5683T max support 6 service slots, MA5680T max support 16 service slots. So MA5683T with smaller chassis.

Q: What is the most hot selling Huawei OLT?
A: MA5683T is the best-selling OLT, next is MA5680T.

Q: Do you provide configuration manual to me if we purchase MA5683T from you?
A: Yes, you may contact our sales representative or out support team.

Q: Can I get technical support from thunder-link.com if we purchase MA5683T from you?
A: Yes, thunder-link.com has experienced technical team on Huawei FTTx solution, however, you may need to purchase technical support service from us as by default we only provide one year hardware warranty.

Q: Does MA5683T support AC power?
A: No, only support DC power, but you can purchase a telecom level AC to DC converter if you just have AC power source.

Q: Does the GPON SFP Module included in the bundle?
A: Yes, with GPBD board, 8 B+ SFP Module are included for free.

Q: Can I use MA5683T main control board SCUN as uplink so as to save the uplink board cost?
A: Yes, you can, but we don’t suggest, as Huawei OLT SCUN load balance is not well supported, so most customers are using SCUN in active/standby mode, if OLT lose power, which SCUN will work as the active SCUN will be randomly, which may affect service, also if the link is down, the active SCUN will not shift to the standby SCUN (it will only shift when SCUN board is down), then service may get affected also.

Q: Can I have 1000 Base-T as uplink?
A: Yes, instead of GICF uplink board you can purchase GICG uplink board, if use GICF, you can buy a electrical SFP module then you can have 1000 Base-T.

Q: What is the difference between different GPON board?
A:

MA5600T Multicast Feature Glance

Definition
Multicast is group communication where data is addressed to a group of destination 
hosts simultaneously. Each multicast address represents a multicast group and all hosts 
in a multicast group can receive the same data. Multicast applies in IPTV,multimedia 
conferencing, and gaming services.

Value
Reduces bandwidth overheads
Each link carries at most one copy of the same multicast data, maximally reducing bandwidth overheads.
Decreases load
Transmitting data in multicast mode decreases video server's and CPU's load and does not significantly increase network's load even if the number of users increases.
Prolongs transmission distance
Multicast packets can be transmitted across network segments,implementing long-distance transmission for large-scale data.
Prolongs transmission distance
Multicast packets can be transmitted across network segments,implementing long-distance transmission for large-scale data.
Application
Multicast applies in the following scenarios: FTTB/FTTC, FTTH, FTTO, as well as OLT user ports connecting to multicast users.

Highlights
Powerful Multicast Capabilities, Improving IPTV Service Deployment
Primary Features Performance
  • 8 K multicast users (1 K= 1024)
  • 4 K multicast programs
  • Concurrent playing of 4000 IPv4 and 2000 IPv6 multicast programs when the SCUH control board is used
  • Multiple levels of multicast data duplication
  • IGMP fast leave
  • 50-ms channel switching
  • 3200-pps IGMP packet processing if the SCUH control board is used
  • Physical-layer G.INP retransmission for better user experience on the IPTV service
  • 900-pps IGMP packet processing on the GPFD board
Features
  • Both IPv4 and  IPv6multicast
  • MLDv1 and MLDv2
  • MLD snooping andproxy
  • IGMPv2 and IGMPv3
  • VPLS multicast
Highlights
Conversion Between M-VLANs and C-VLANs, Implementing Multiple CPs Sharing One ONT and Supporting Open Access

The multicast data transmission meets the service requirement of multiple CPs renting different ports on the same ONT in the open access scenario, improving revenue from resources.
Layer 3 Multicast for Flexible Multicast Group Address Usages
The programs issued from different multicast sources can use the same group IP address (GIP).
Compared with Layer 2 multicast, Layer 3 multicast relieves GIP limitations due to group MAC address (GMAC) conflict.

Highlights
Comprehensive Fault Locating Methods, Facilitating Rapid Multicast Service Fault Rectification
User Log Identify causes for program ordering failures by querying user logs or fault-related operation records.
IGMP Statistics Identify IGMP packet transmit and receive issues based on IGMP packet statistics.
Multicast Traffic Statistics Based on multicast traffic statistics, determine whether:
  • Multicast data has arrived at the inbound or outbound port on the MDU at the data forwarding layer.
  • The transmission rate is excessively low.
  • Packet loss has occurred.
Multicast Emulation Emulate program ordering performed by a multicast user to locate faults by querying traffic and user information in real time.

How to Troubleshoot the Failure on GPON

An ONU connected to a GPON port of an OLT fails to go online normally, but the queried Run state of the ONU is displayed as offline by running the display ont info command on the OLT.
Location Method
NOTE:
Going online refers to a process that after being powered on, an ONU registers with an OLT and sets up a management channel with the OLT. An ONU can be managed by the OLT and be configured with services only after going online.
When an ONU fails to go online, locate the fault based on the following fault symptoms and possible causes.
Possible Cause
Judgment Criterion
Troubleshooting Method
The SN configured on the OLT is different  from the actual SN of the ONU; hence, the ONU fails to pass authentication  and to go online.
 Run the display ont info command to query the ONU information. It is  found that the SN in the result is different from the actual ONU SN.
Run the ont add command to re-add an ONU  and specify the correct ONU SN and password.
 NOTE:
 The ONU with a different SN is regarded as a new one and is founded by the  OLT.
The actual distance between the ONU and  OLT exceeds the ranging compensation distance configured on the OLT.
Run the display port info command to  query the minimum logical reach (Min distance) and maximum logical reach (Max  distance) configured for the GPON  port. It is found that the actual distance between the ONU and OLT exceeds  the ranging compensation distance.
 For example, the actual length of the optical fiber between the ONU and OLT  is about 25 km, which exceeds the ranging compensation distance of 0-20 km.
Run  the port range command to adjust the minimum logical reach and maximum  logical reach so that the actual distance between the ONU and OLT is within  the ranging compensation distance.
 NOTE:
 By default, the ranging compensation distance of a GPON port is from 0 km to  20 km.
 According to Class B+, the maximum logical reach of a GPON port must not  exceed 60 km, and the difference between the minimum logical reach and  maximum logical reach must not exceed 20 km.
The OLT deactivates the ONU.
Run the display ont info command to query  the ONU information. It is found that Control flag is displayed as deactive.
Run the ont activate command to activate  an ONU.
 NOTE:
 When an ONU is activated, its optical module only receives optical signals  but does not transmit optical signals.
The laser on the PON port is disabled.
Run the display port info command to  query the information about the PON port. It is found that Laser switch is in  the Off state.
Run the port laser-switch command to  enable the laser on the PON port.
 NOTE:
 By default, the laser on a GPON port is enabled.
The PON port is faulty.
If  either of the following two situations occurs, the PON pot is faulty.
 Run the display port state command to query the status of the PON port. It is  found that abnormal items exist in the query result. For example, the laser  status (Laser state) is abnormal and the transmit optical power (TX power)  exceeds the normal range (1.5-5.0 dBm).
 Migrate the service to another port. It is found that the ONU goes online  normally.
Replace the optical module of the PON  port or replace the board.
The board or the slot is faulty.


 All the ONUs connected to the board fail to go online.


 Change the board to another slot. If the fault persist, replace the board.
CAUTION:
To facilitate fault report, save the results of the following steps.
The parameters of the optical module in this topic comply with Class B+. Note that such parameters are slightly different from the parameters in Class C.
Procedure
1.When the queried Run state of the ONU is displayed as offline, check whether the OLT generates the following alarms. If such alarms are generated, clear them and check whether the fault is rectified. If the fault persists, proceed to 2.
The following alarms may be generated:
2.Check for the possible causes on the OLT and troubleshoot the faults accordingly. If the ONU still fails to go online after that, proceed to 3.
