We have OLT:

OLT_VACANTE#display version

  VERSION : MA5600V800R018C00

  PATCH   : SPH102

  PRODUCT : MA5680T


with the following TOPA board:

     1  E1    fault   HDB3    -          line   no loop  enable    -    

etc


We want to transmit E1 service from a CO to a PBX through the OLT-ONT pair over GPON.

We try to configure CESoP service, so we at first configure TDM VCL:


OLT_VACANTE(config)#tdm-vcl tdm-vcl-id 0 cesop 0/4/0 timeslot 0xffffffff 

{ <cr>|timeslot-zero-extend<K> }:


  Command:

          tdm-vcl tdm-vcl-id 0 cesop 0/4/0 timeslot 0xffffffff 

  Failure: The port type is invalid


Unsuccessfully as you see. 

What means the message: "The port type is invalid"?

What have we missed?

Hi, I cannot set the SDT mode. Here is all available commands for the TOPA ports:

OLT_VACANTE(config-if-top-0/4)#?
---------------------------------------------
Command of top 0/4 Mode:
---------------------------------------------
clear <Group> clear command group
clock-work Setting the clock-work
display Display information
impedance Setting the impedance
interface <Group> interface command group
line-code Setting the linecode
loopback Setting the loopback
quit Exit from current mode and enter prior mode
return Enter the privileged mode
set Set system attribute
switch Switch language mode
tdm TDM
undo Negate a command or set its defaults

Now the port in issue has the state:
OLT_VACANTE(config-if-top-0/4)#display port state 0
---------------------------------------
Port : 0
State : normal
LineCode : HDB3
Impedance : -
ClockWork : line
LoopType : no loop
RtpState : enable
Alarm : no alarm
Frame mode : -
---------------------------------------

I cannot set "Frame mode".

3.2.2.2  Enterprise DDN Private Line Access Service

Enterprise DDN private line service is converted to E1 signals. ONUs access the E1 signals and transmit them in Native TDM mode.

3.2.2.2.1  Service Requirement and Application Scenario
Service Requirement

The DDN private line service is widely used in financial departments, governments, and enterprises that require highly real-time data switching. It provides a rate from 64 kbit/s to 2 Mbit/s. GPON access in OLT+ONU mode can access the DDN private line service along with other data services and voice service. This access mode does not require independent maintenance of the DDN network, simplifying network architecture.

Application Scenario

As shown in Figure 3-8, a protocol converter is deployed between an ONU and DDN node machine to convert DDN private line services to E1 services. The ONU accesses the E1 services and encapsulates the service packets in TDM over GEM mode and then transmits the packets to the OLT. The OLT decapsulates the service packets to E1 data and transmits the data to the SDH network through upstream E1/STM-1 ports, achieving transparent transmission of DDN services.

3.2.2.2.2  Adding ONUs to an OLT

This topic describes how to add optical network units (ONUs) to an optical line terminal (OLT). ONUs can be configured only after they are added to the OLT successfully.

Context

  • When adding ONUs, you need to bind related profiles to the ONUs, including the DBA profile, line profile, and alarm profile.
  • An ONU can be added in two modes: offline addition and online confirmation. Select either mode as required.
Data Plan
Table 3-12  Key data plan

Configuration Item

Data

DBA profile

DBA profile for the management service: dba-profile_1 (system default)

DBA profile for the private line service:
  • Profile ID: 21
  • Profile type: fixed bandwidth and minimum delay
  • DBA bandwidth: 28928 kbit/s (If an ONU connects to four E1 private lines, each line has a recommended DBA bandwidth of 7232 kbit/s.)
    NOTE:
    • DBA bandwidths must be in the minimum delay mode.
    • Fixed bandwidths must be used.

Line profile

Profile ID: 11

T-CONT ID: 1 (for the private line service)

NOTE:
  • The recommended T-CONTs are T-CONT 1, T-CONT 2, and T-CONT 3. Other T-CONTs cannot carry the TDM service.
  • Do not configure the T-CONT ID of the TDM service to be greater than the ID of the T-CONT bound to dynamic bandwidths.
  • Use a T-CONT for all E1 services.
  • Do not use a T-CONT for E1 and Ethernet services.

GEM port ID for DDN private line service: 13

Service profile

Profile ID: 11

Ethernet and POTS port capability set: adaptive

TDM port capability set: 4

NOTE:

The capability set of the service profile must be greater than or equal to the capability set of the device. Otherwise, some ports fail to be configured.

Networking data

PON port: 0/3/1

ONU parameters:
  • ONU ID: 1
  • SN: 32303131B39FD641

Procedure

  1. Configure GPON ONU profiles.
    1. Configure a DBA profile for the private line service. Enable the bandwidth compensation function and set the DBA bandwidth allocation mode for the GPON port to minimum bandwidth delay.

      huawei(config)#dba-profile add profile-id 21 type1 fix 28928 bandwidth_compensate yes
      huawei(config)#interface gpon 0/3
      huawei(config-if-gpon-0/3)#port dba bandwidth-assignment-mode 1 min-loop-delay
      huawei(config-if-gpon-0/3)#quit

    2. Configure an ONU line profile.

      huawei(config)#ont-lineprofile gpon profile-id 11
      huawei(config-gpon-lineprofile-11)#tcont 1 dba-profile-id 21  //Bind T-CONT 1 to DBA profile 21
      huawei(config-gpon-lineprofile-11)#gem add 11 eth tcont 2 
      huawei(config-gpon-lineprofile-11)#gem add 13 tdm tcont 1 //Add GEM port 13 to T-CONT 1.
      huawei(config-gpon-lineprofile-11)#gem mapping 13 1 e1 1 //Map GEM port 13 to E1 port 1 on the ONU.
      huawei(config-gpon-lineprofile-11)#commit
      huawei(config-gpon-lineprofile-11)#quit

    3. Configure an ONU service profile.

      huawei(config)#ont-srvprofile gpon profile-id 11
      huawei(config-gpon-srvprofile-11)#ont-port eth adaptive pots adaptive tdm 4
      huawei(config-gpon-srvprofile-11)#commit
      huawei(config-gpon-srvprofile-11)#quit

    4. (Optional) Configure an alarm profile.

      • The default GPON alarm profile ID is 1. The value of each alarm threshold is 0 which indicates that alarms are not reported.
      • In this example, the default alarm profile is used and no configuration is required.

  2. Add ONUs to the OLT.
    1. Add ONU 3 in offline mode.

      huawei(config)#interface gpon 0/3
      huawei(config-if-gpon-0/3)#ont add 1 ontid 1 sn-auth 32303131B39FD641 
      omci ont-lineprofile-id 11 ont-srvprofile-id 11
      

    2. (Optional) Bind an alarm profile.

      By default, an ONU will be automatically bound to alarm profile 1 (default profile). You need to manually bind an alarm profile to an ONU only when the default alarm profile does not meet requirements.

      In this example, the default alarm profile is used. Therefore, you do not need to manually bind an alarm profile.

  3. Confirm the ONU status.

    After adding an ONU, run the display ont info command to query the current status of the ONU. Ensure that Control flag is active, Run State is online, and Config state is normal.

    The following uses ONU 1 as an example to describe how to confirm ONU status.
    huawei(config-if-gpon-0/3)#display ont info 1 1
      ---------------------------------------------------------------------         
      F/S/P                : 0/3/1
      ONT-ID               : 1                                                      
      Control flag         : active    //Indicates that the ONU is activated.                             
      Run state            : online    //Indicates that the ONU is online.                          
      Config state         : normal    //Indicates that the ONU is in normal state.                      
    ...//Other command output is omitted.
    huawei(config-if-gpon-0/3)#quit

Follow-up Procedure

When Config state is failed, Run state is offline, or Match state is mismatch:
  • If Control flag is deactive, run the ont active command in GPON mode to activate the ONU.
  • If Run state is offline, a physical line may be broken or the optical module may be damaged. Check the line and the optical module.
  • If Config state is failed, the configured ONU capability exceeds the actual ONU capability. In this case, run the display ont failed-configuration command in the diagnose mode to check the failed configuration item and the failure cause. Then, rectify the fault accordingly.
  • If the ONU does not match, that is, Match state is mismatch, the port types and number of ports undermatch the actual port types and number of ports supported by the ONU. In this case, run the display ont capability command to query the actual capability of the ONU, and then select one of the following modes to modify the ONU configuration:
    • Create a proper ONU profile according to the actual capability of the ONU, and then run the ont modify command to modify the configuration data of the ONU.
    • Modify the ONU profile according to the actual capability of the ONU and save the modification. Then, the ONU automatically recovers the configuration successfully.
3.2.2.2.3  Configuring TDM Connections

This topic describes how to configure Native TDM connections between GPON ports and E1/STM-1 upstream ports to transmit E1/STM-1 private line service data.

Prerequisites

Required hardware is available:
  • TOPA+NH1A for upstream transmission through E1
  • TOPA+O2CE for upstream transmission through STM-1
  • GPON board: GPBC, GPBD
Background Information

The OLT can transmit data to the SDH network through E1 or STM-1 lines. Each E1 line provides 2 Mbit/s bandwidth. After being mapped, aligned, and encapsulated, 63xE1 signals are multiplexed into one STM-1 signal through VC12. One STM-1 line provides 155 Mbit/s.

When the OLT transmits data to SDH equipment through STM-1 lines, pay attention to the VC12 mode and VC12 number.
  • When the OLT is interconnected with Huawei SDH equipment, the VC12 mode is huawei and the VC12 numbers on the OLT and the SDH equipment must be consistent.
  • When the OLT is interconnected with Lucent SDH equipment, the VC12 mode is lucent. The VC12 numbers has the following mapping relationships (which can be queried using the display vc12-mode-table command):

    Huawei: Mapping between the multiplexing number and VC12 number: VC12 number = (TUG3–1) + (TUG2–1) x 3 + (TU12–1) x 21

    Lucent: Mapping between the multiplexing number and VC12 number: VC12 number = (TU12–1) + (TUG2–1) x 3 + (TUG3–1) x 21

When configuring the coding mode for the E1 ports on an MA5673, ensure the same configuration on all ports. The reason is that the coding mode configured on an OLT is by port while on an ONU is by board.

Data Plan

Upstream Transmission Mode

Data

Upstream transmission through E1

Port on the TOPA board: 0/5/0

Daughter board type: NH1A (provides E1 ports)

Upstream transmission through STM-1

Port on the TOPA board: 0/5/0

Daughter board type: O2CE (provides STM-1 ports)

VC12 number: 0
NOTE:
The VC12 parameter must match that on the interconnected SDH equipment. Otherwise, services fail.

Procedure

  • Configure a TDM E1 connection for E1 upstream transmission.

    huawei(config)#tdm-connect connectid 1 tdm 0/5/0 gpon 0/3/1 ontid 3 gemportIndex 13
    

  • Configure a TDM E1 connection for STM-1 upstream transmission.

    huawei(config)#tdm-connect connectid 1 tdm 0/5/0 vc12 0 gpon 0/3/1 ontid 3 gemportIndex 13
    

3.2.2.2.4  Configuring Clock Synchronization

Clocks on an entire network can be synchronized through an E1 or STM-1 line clock.

Prerequisites

The clock daughter board CKMC has been configured on the SCU control board.

Context

Configuration roadmap for clock synchronization:
  1. The OLT traces the upstream E1/STM-1 line clock of the TOPA board as the system clock.
  2. The system clock is delivered to an ONU through optical paths of the GPON board.
  3. The ONU uses the line clock of the GPON upstream port as the system clock.
  4. The ONU E1 transmit clock is synchronized with the system clock of the ONU.

Procedure

  1. Add a system clock source.

    Run the clock source command to configure the line clock of E1 or STM-1 port 0/5/0 on a TOPA board as the system clock source with ID 0.

    The clock module automatically determines the specified clock source type (E1/STM-1), selects a clock source as the reference clock source according to priority, and performs phase lock.

    huawei(config)#clock source 0 0/5/0

  2. Configure the priority of the system clock source.

    Run the clock priority command to configure the highest priority for the reference clock source with ID 0.

    huawei(config)#clock priority system 0

  3. Query the configuration and status of the system clock source.

    Run the display clock source system command to query the configuration and status of the system clock source. Ensure that configurations of the system clock source are correct and the status is Normal.
    huawei(config)#display clock source system
      ------------------------------------------------------------------------------
      Index  Board    Source   Clk-type  State       Priority QL    Selected        
      ------------------------------------------------------------------------------
        0    H801TOPA 0/5/0    E1        Normal      0        ---   YES             
      ------------------------------------------------------------------------------
    
    Run the display clock mode command to query the clock working mode. Ensure that the clock daughter board works in tracing mode.
    huawei(config)#display clock mode
      Clock manage-mode:Third-mode
      Clock subboard work-mode:Tracing

  4. Configure the ONU clock.

    huawei(config)#ont-srvprofile gpon profile-id 11
    huawei(config-gpon-srvprofile-11)#port e1 1 tx-clock system   //The system clock is used. An adaptive clock can also be configured here (set tx-clock to adapt).
    huawei(config-gpon-srvprofile-11)#commit
    huawei(config-gpon-srvprofile-11)#quit

3.2.2.2.5  Verifying Services

This topic describes how to use the PDH or SDH tester to verify the private line access service.

Prerequisites

The private line service has been configured.
Networking

imgDownload?uuid=107263cf610447e7a07d70e
Figure 3-10  Test setup for STM-1 upstream service
imgDownload?uuid=c03cbaa1771545d98a9bbbc

Procedure

  1. Set up network environment according to the preceding diagrams for service acceptance tests.

    imgDownload?uuid=aa42decfb5c04bb3b6ebe84 NOTE:
    Ensure clock synchronization for the test. It is recommended that the tester use the internal free-run clock, the OLT trace the clock of the tester, and the ONU trace the clock of the OLT.

  2. Use the E1 or STM-1 line tester to send packets for the test.

    The test duration must be 12 hours or longer. There should be no alarms on the tester and the bit error rate must be less than 1E-9.

Follow-up Procedure

When the test on service connectivity fails, you can check for the failure causes by performing loopbacks. The following loopbacks are supported:
  • Remote loopback on the OLT TOPA board
  • Local loopback on the OLT TOPA board
  • Local loopback on the ONU
  • Remote loopback on the ONU
