Brief Introduction of Huawei SSND0SLQ16(L-16.1,LC) Board

SSND0SLQ16(L-16.1,LC), 4xSTM-16 Optical Interface Board(S-16.1,LC), is a SDH service board in Huawei OSN 2500, OSN 3500, OSN 7500 system. You may find the different name about it, like SSND0SLQ16(L-16.1,LC), SSND0SLQ1603, SSN1SLQ16A12, actually it is the same item described.

The SSND0SLQ16(L-16.1,LC) is a line board and is available in three functional versions, namely, N1, N2, and N4.The N2SLQ16 is discontinued.

The SSND0SLQ16(L-16.1,LC) can be used on the Huawei OptiX OSN equipment series to transmit and receive STM-16 optical signals. The SSND0SLQ16(L-16.1,LC) converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SSND0SLQ16(L-16.1,LC) converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

The SSND0SLQ16(L-16.1,LC) can be installed in slots 1–4, 15, and 16, in OSN3500 system. In this case, two optical interfaces can be configured. It also can be installed in slots 5–8 and 11–14. In this case, four optical interfaces can be configured.

The feature code of the SSND0SLQ16(L-16.1,LC) indicates the type of optical interface.

The feature code of SSN1SLQ1603, SSN2SLQ1603 is 03, that stand for the type of Optical Interface is L-16.1. And the feature code of SSN1SLQ16A12 is 12, and the type of Optical Interface is also L-16.1.

There are some parameters that differ from the series board of SSND0SLQ16(L-16.1,LC), which are: (I-16), its transmission distance is 0~2km; (S-16.1), 2~15km, (L-16.1), 15 to 40km, and (L-16.2), 40 to 80km.

The characteristics of the optical interfaces comply with ITU-T G.957 and ITU-T G.692.

The SSND0SLQ16(L-16.1,LC) supports the CWDM and DWDM colored optical interfaces. The optical interface uses the LC connector. The CWDM optical interface supports the transmission distance of 80 km, and the DWDM optical interface supports the transmission distances of 120 km. 

How to Connect the PC when do Huawi OSN 3500 Commissioning?

The per-NE commissioning is performed by using the U2000 on a PC. This section describes how to connect the PC to the equipment properly. Make sure that the connection between the PC and the equipment is correct during the commissioning.

Prerequisites

The Windows operating system must have been installed on the PC for commissioning.

Tools, Equipment, and Materials

None.

Procedure

1. Make sure that the network cable is a straight-through cable. For details about the straight-through cable, see Straight-Through Cable in Hardware Description.
    NOTE:

   If a self-adaptive network adapter is installed on the PC, a cross-over cable can also be used.

   For details of the cross-over cable, see Crossover Cable in Hardware Description.
2. Connect the PC to Huawei OptiX OSN equipment, as shown in Figure 1.
   Figure 1 Connection between the PC and the OptiX OSN equipment 
   
    NOTE:

   In this example, the connection between the OptiX OSN 3500 and a PC is used as an example. The method of connecting other types of equipment to a PC is the same as that of connecting Huawei OptiX OSN 3500 to a PC, except that the auxiliary boards and their slot IDs are different. For the auxiliary boards and their slot IDs on the other types of equipment, see the Hardware Description of the corresponding equipment.
3. Power on the PC. Check the ETH port indicators of the PC and the auxiliary board. Normally, the LINK indicator is steady green, and the ACT indicator flashes orange.
   
   
    NOTE:

   In the case of a network that has only one gateway NE, the gateway NE is connected to the NMS through the ETH port, and the other NEs are connected to the gateway NE through the optical fibers.
4. Power on the PC. The Microsoft Windows starts automatically and the login window is displayed.
5. Log in with an administrator account.
6. Click OK to display the desktop of the Windows operating system.

Universal Switch Architecture for Multiservice Grooming

Huawei OptiX OSN equipment uses a universal switch architecture for unified grooming of packet services and TDM services. OptiX OSN equipment can work in packet mode, TDM mode, or dual-domain (packet+TDM) mode.

The three modes can be smoothly switched by upgrading the software of a service board so carriers' requirements on services and networks can be met. The smooth switching between the three modes supports carriers' distributed smooth investment based on the development of the technology and industrial chain.

Based on a universal switch architecture, OptiX OSN equipment OSN 3500 uses the packet transmission technology to perform efficient statistical multiplexing on data services so the transmission cost of every bit is reduced. In addition, OptiX OSN equipment uses the Native technology to transmit TDM services so voice services are transmitted with high quality.

Figure 1 OptiX OSN equipment architecture 

Based on a universal switch architecture, OptiX OSN equipment unifiedly transmits packet services such as 2G, 3G, and VIP private line services so network overlapping is avoided. In addition, OptiX OSN equipment transmits TDM services. Carriers can constitute an end-to-end packet network, dual-domain (packet+SDH) network, or STM-64 board and Hybrid (MSTP+routers) network that bears L2+L3 services. This complete packet transmission solution allows an evolution from TDM networks to all-IP networks
