The OptiX PTN 3900 and PTN 1900 are are a new generation metropolitan optical optical transport equipment, equipment, which is developed by Huawei Huawei for packet transport. 

As emerging data services are widely applied, operators require increasing bandwidth of the transport network and demand more flexibility of scheduling bandwidth. As a circuit-switching network, the traditional SDH-based multiservice multiservice transport network is inapplicable inapplicable to the data services that feature burst and flexibility. In addition, the traditional connectionless-oriented connectionless-oriented IP network should not be used as a telecommunication telecommunication carrier network because it cannot strictly ensure the quality and performance of important services.

The figure shows a typical scenario where where the offload solution is applied. Node B connects to the OptiX PTN 1900 through the ATM IMA interface. The IMA E1 module of the OptiX PTN 1900 accesses the services and distinguishes distinguishes various service flows flows according to the VPI/VCI values carried by the packets. 

In the case of the HSDPA service flow, the OptiX PTN 1900 emulates the ATM PWE3 for the service flow on the access side and then encapsulates the emulated service into the tunnel as required by the WMS network. Finally, the OptiX PTN 1900 transports the service to the ADSL modem through the FE interface. When the encapsulated service enters the ADSL ADSL network, the service service is transported to the OptiX PTN 3900. Then, the OptiX PTN 3900 decapsulates the service and transports the service to the radio network controller controller (RNC). (RNC).

CES Service


Page19

Circuit emulation service service (CES) is realized by encapsulating the TDM service data based on special circuit emulation packet headers. In this way, a special packet header carries the frame format, alarm, alarm, signaling, synchronization, and timing information of a TDM service flow. The encapsulated packet is called PW packet. The MPLS protocol carries PW packets, which travel through the corresponding packet transport network (PTN) and then are decapsulated when arriving at the PW egress. Finally, a TDM circuit switching service flow is re-created.

Application Mode The CES service allows a metropolitan Ethernet network (MEN) carrier to provide TDM services to customers that have only the TDM equipment. This enlarges the service range and the number of users of the MEN carriers, and provides a way to transform the traditional circuit network to the wideband data network. The CES service mainly applies to the wireless service and the enterprise private line service. The application scenarios include UNI-NNI and UNI-UNI, UNI-UNI, as shown in this figure. 

UNI-NNI UNI-NNI CES service: The PTN equipment accesses the TDM services of customers by using the TDM or channel STM interface. The CES PW can be created between the PTN equipment to emulate the end-to-end TDM service. To customers, the CES services are similar to actual TDM services.



UNI-UNI CES service: service: The PTN equipment accesses the TDM services by using a single point.

NOTE: 

Only the point-to-point service is supported. That is, the service of one E1 interface mapping to one PW is supported. But converged services of several TDM interfaces mapping to one PW are not supported.

ATM Service

Asynchronous transfer mode (ATM) is a technology used to transport packets in cells with ensured QoS. ATM meets the requirements of real-time services and non-real-time services. services. The PTN equipment supports using the PWE3 technology to emulate ATM services. That is, the PTN equipment accesses the ATM services on the source node, encapsulates ATM cells in PW to transmit transmit them to the sink node, and then decapsulates the ATM cells. In this way, the ATM services are emulated. ATM emulation services mainly apply to wireless services. The application scenarios include UNIs-NNI and UNI-UNI, as shown in the figure. 

UNIs-NNI UNIs-NNI ATM service: The PTN equipment accesses the ATM services of customers by using the IMA link or STM link respectively. You can create the ATM PW between the PTN equipment to emulate end-to-end ATM services. At the source end, the ATM cells are encapsulated in the PW. Then, data packets are transparently transmitted in the MPLS network. At the sink end, the ATM services are decapsulated and forwarded to the connected customer network. To customers, the UNIs-NNI ATM services are similar to actual ATM services.



UNI-UNI ATM services: services: The PTN equipment switches and transmits the ATM services at a single point.
