Huawei MA5600T/MA5603T/MA5608T supports integrated fiber-copper access and access-aggregation integration

MA5600T/MA5603T/MA5608T of the all in one platform 

Fiber-Copper Integration

The MA5600T/MA5603T/MA5608T enables optical fibers and copper lines to be integrated in one platform, which ensures that the access network can smoothly evolve from copper line access to optical fiber access.

• Optical fiber access: The MA5600T/MA5603T/MA5608T supports GPON, 10G GPON, and P2P optical fiber access, satisfying the requirements of the FTTH, FTTB, FTTC, FTTO, FTTM, and FTTW scenarios.
• Copper line access: The MA5600T/MA5603T/MA5608T supports ADSL2+ (compatible with ADSL), VDSL2 (compatible with ADSL2+), SHDSL, and POTS voice services. The MA5600T/MA5603T/MA5608T supports multiple copper line access modes and makes full use of existing copper line resources to provide users with rich and flexible network services. In addition, the MA5600T/MA5603T/MA5608T can function as a DLSAM to be used in copper access only, or as an MSAN to be used in integrated fiber-copper access.

Access-Aggregation Integration

The MA5600T/MA5603T can implement FTTH/DSLAM access and FTTB/FTTC/DSLAM Ethernet aggregation in the same subrack to provide a unified traffic aggregation point on the FTTH/FTTC/FTTB/FTTD network, thereby achieving aggregation of different network construction modes, eliminating the need to construct an independent access-aggregation network layer, and simplifying the network architecture.

• The MA5600T supports a maximum non-aggregation forwarding capability of 40 Gbit/s x 16 GE.
• The MA5600T and MA5603T support the 48-port high-density aggregation board and provide access for a maximum of 768 GE ports.
• The OLT supports Layer 3 functions and can be used as an aggregation edge device. It possesses powerful Layer 3 service processing capabilities, such as 40G switching capability and 60 Mpps Layer 3 forwarding capability in the 8 x 10 GE upstream load-sharing mode. With these capabilities, the OLT can:
  • Reduce upper-layer service traffic and shorten network transmission delay. Specifically, the OLT can perform Layer 3 switching for local traffic, thereby lowering the traffic pressure of the upper-layer network and pressure of network traffic expansion.
  • Simplify the network architecture. Specifically, Layer 2 aggregation switches do not need to be deployed, thereby streamlining the network layers.
  • Improve network security. Specifically, the upper network does not learn the user-side MAC addresses, thereby eliminating the risks of MAC spoofing and broadcast storms.
• The MA5600T and MA5603T support the mature all-service MPLS solution.
• Huawei MA5600T and MA5603T support service transmission over ATM PWE3, TDM PWE3, ETH PWE3, VPLS, and L2VPN.
• The MA5600T and MA5603T feature high service performance. Specifically, they support quick E2E service protection (service switching time: ≤ 200 ms).
• The MA5600T and MA5603T do not have limitations on service authentication and terminal VLAN planning, simplifying network design and maintenance.

What Is the Relationship Between the LOF and LOS Alarms?

How to detect LOF and LOS alarms and what is the relationship between these two alarms? What alarm is generated if optical fibers are removed when the Huawei MA5606T or MA5652G serves as an Huawei ONU?

LOF indicates loss of frame. When such an alarm is generated, the ONU can receive optical signals. LOS indicates loss of signal. When such an alarm is generated, the ONU fails to receive optical signals. The mechanisms of detecting LOFi and LOSi alarms are as follows:

• LOFi: If four consecutive frames of an OLT fail to locate an upstream frame of an ONU, the LOFi alarm is generated and the ONU goes offline.
• LOSi: If four consecutive frames of an OLT MA5600T fail to receive an upstream optical signal of an ONU, the LOFi alarm is generated and the ONU goes offline.

The relationship between the LOF and LOS alarms is as follows:

• Use an optical attenuator to test the ATM 155/622 Mbit/s optical port and increase the attenuation gradually. It is found that the alarm status changes as follows: normal -> SD -> LOF -> LOS. This indicates that after LOF is generated, if the attenuation is increased further, no optical signal is received and LOS is generated. If an optical fiber is removed, LOF may be generated first and then LOS, which is related to the alarm detection mechanism. The LOSi, LOFi, and LCDGi alarms are detected in the time window mode. In the first several detections, if the time window detects the threshold for frame losing, the LOFi alarm will be generated.
• If the PON line generates an LOF alarm, LOS will not be generated. This is because the PON port uses the time division system. If an LOF alarm is generated, the ONT goes offline and then the OLT does not assign the timeslot (bandwidth) to the ONU. Therefore, the OLT does not detect whether the ONT transmits upstream optical signals and an LOS alarm is not generated.
• If LOS is generated, LOF/SD will be suppressed. This is because LOS is the alarm of the highest severity.

When the MA5606T and MA5652G serve as an ONU MA5628 and the optical patch is normal, LOS is generated when an optical fiber is removed.

Different interface modules have different service boards. For details about working principle of an interface module, see the description of the corresponding service board in the Hardware Description.

This section describes the flows of various of access services.

• Service flows passing the Ethernet switching module and then the upstream interface module for upstream transmission, including GPON service flow (GE/10GE upstream), P2P service flow (Ethernet upstream), xDSL service flow (GE/10GE upstream), Converting the native TDM service into E1/STM-1 service flow (E1/STM-1 upstream). Converting the native TDM service into E1/STM-1 service is the native TDM service that is transmitted through GPON is converted by the MA5600T/MA5603T/MA5608T. The device terminates the native TDM service, and transmits the service to the network-side device through E1/STM-1.
• Service flows passing the Ethernet switching module, related service processing modules, and then the Ethernet switching module for upstream transmission. Such service flows convert the native TDM service into SAToP service and POTS service that use GE/10GE for upstream transmission. In this service flow, the native TDM service that is transmitted through GPON is converted by the MA5600T/MA5603T/MA5608T. The device encapsulates the native TDM service into PWE3 service. Therefore, this service flow is also called converting the native TDM service into TDM PWE3 service. The purpose of this service flow is to ensure the emulation transmission of the TDM service.

N2000BMS shows the alarms with an early hour because the NE does not have configured the right time zone

Issue Description

The alarms displayed in the N2000BMS are displayed with an early hour.
The alarm is reported in the OLT MA5600V800R007
Example:
the next alarm is reported in Huawei MA5600T at 01:39:49-05:00, but, in the N2000BMS appear the same alarm at 02:39:49. The time in the N2000BMS is the real time.

Handling Process

Because of the BMS had the correct time, so, it was supposed that the DST was not configured in the NEs.
It was analyzed the time settings and the time zone  in Huawei OLT.

Ceylan(config)#display time                                                  
{ <cr>|dst<K>|time-stamp<K> }:                                                 

  Command:                                                                   
          display time                                                       
  2011-11-02 10:10:03-05:00                                                                                                                                 
Ceylan(config)#display timezone                                              
The current time zone:  GMT-05:00
it was found that the timezone is not the correct. So it was requested change the timezone to make a test.

After modify the time zone to the correct one, the alarms was reported in the N2000BMS with the correct time.
However, to avoid changing the timezone every period of time, it was suggested to enable the DST.

Ceylan(config)#display time dst                                              
  Failure: DST has not been configured  
  

Suggestions

Verify the timezone of the country to set the correct one in the NE or in the Server. Also, consider use the DST feature.

Logical fiber still green even if real fiber is cut and we have R_LOS alarm

Issue Description

Customer M complains the following problem:
we have real fiber cut and R_LOS alarm is reported, but the logical fiber color on U2000 topology is still green even if the relevant port reports R_LOS. This makes customers maintenance difficult to report fiber cut on time and they pushed Huawei CS to solve the problem ASAP.
Please check the pictures attached in "problem scene" file to see the problem.

Alarm Information

R_LOS on port but relevant fiber does not become red.

Handling Process

To solve this problem you can do as following:
1) Stop fault process in sysmonitor.
2) Use "root" user to login your running service server.
3) Put the files in the attachment of this case (input.sql and IPServiceNum.sh) in server path /tmp
Note: use bin format to load these files to server.
4)modify this file right by this command:
cd /tmp
chmod +775 IPServiceNum.sh
5)do this file script by this command:
sh IPServiceNum.sh
6) after that, the system will ask you to input some information : please input like following OSS_ROOT:/opt/U2000
database server name: DBSVR
database user : sa
database password: by default it is null, but if you have changed it you need to enter current password
7) start fault process in sysmonitor.
8) Clear R_LOS alarm manually in NMS, after you clear this alarm, and if this fiber still cut, the R_LOS for this fiber will be reported to NMS again, then this fiber will be turned to red in NMS.

Root Cause

After analyzing this problem we found that the root cause of the problem is the following:
During installing instance, the information for file ipe2emgr_alarm_define_ext.xml can not put the alarm information into the table tbl_cur_alm which made the fiber remains still green even if we have R_LOS alarm in the corresponding port.

Suggestions

If you have the same case in your site, please to check with R&D before performing the procedure described in this case. If they confirm the solution according to your site specifications then you can try it.

How to configure the Management Channel Between OLT and ONU?

How to synchronize U2000 server with more than one NTP server, and peers?

Issue Description

This case applies to situation when, when deploying U2000 server on SUN Solaris platform, in both single-server and High Availability configuration.
This solution was deployed with U2000 V100R002C01SPC100, but it will most certainly work with other versions.
Standard NTP configuration, with MSuite, allows us to configure just one time server. However client can request to have his server (servers) have more than one NTP sources configured, for redundancy purpose.
In this case we have to manually edit Solaris NTP configuration file.

Alarm Information

Null

Handling Process

In SUN Solaris OS NTP configuration file is in directory /etc/inet/ntp.conf. If it's not there, an example file exist in /etc/inet/ntp.server, which can be used as a template.
In the file we can put our lists of time servers in a format:

server X.X.X.X
server Y.Y.Y.Y
...

If we have more than one server with same STRATUM level, we can configure it as a proffered one, using keyword "prefer".

server X.X.X.X prefer

In case when we have U2000 in HA configuration, we can set master and stand-by servers as peers. This is helpful when all configured time servers will become unavailable. Both U2000 server can then configure right time between themselves. Example configuration:

peer Z.Z.Z.Z

Root Cause

Null

Suggestions

Important thing to remember is that from all time servers on the list system will choose the one with lowers (more reliable) STRATUM level. If we have few server on the same level, and no server with better value then we can use keyword "prefer" to force one servers to be used.
In configuration file we can also find server with ip address 127.127.1.0. This is LOCAL time, server's time. To make sure this time source is used as a last one, we should set its STRATUM value to less preferable. This can be done by using keyword "fudge".

server 127.127.1.0
fudge 127.127.1.0 stratum 10

Same method can by used to change STRATUM value of any real server but only to less preferable value. For instance, when server is broadcasting its time with STRATUM value of 3, we can change it locally to 4,5,6 etc, but never 0,1 or 2.

Summing up, an example file in situation when we have U2000 in HA configuration and two time servers with same STRATUM level in out network should look like this.

server 172.16.1.15 prefer
server 172.16.2.15
server 127.127.1.0
fudge 127.127.1.0 stratum 10

peer 172.16.10.10

In HA configuration each U2000 server needs to have his NTP configured separately, which means it has to have its own ntp.conf file with proper settings.
