Cost-effectiveness of integrated access network device transmission

Integration of access networks: cost-effective transmission of devices; Integration of access networks is a common problem. But how can we set more precise integration of access networks to facilitate our use?

To adapt to the fierce competition in the integrated exchange/access network market, Shanghai Bell launched an integrated transmission solution for modules/access networks-Blu-ray module ODM ). Blu-ray module ODM) is a series of Shanghai Bell transmission products.

It provides an integrated optical fiber transmission networking function for Shanghai Bell's existing access network products GA, Switching Module JRSU, and integrated access module VSAN and VSAN plus. It can also be used as an independent optical fiber transmission device, suitable for a variety of complex access networks and domestic network transmission networks. The blu-ray module ODM has the following advantages:

Integrated Access Network Device for value-added exchange

The blu-ray module adopts the standard SDH Protocol and is closely integrated with existing products in the market through clever conception and technical transformation. This not only reduces the space occupied by devices, but also reduces equipment costs, it also reduces the number of installation projects. The device is built in the original device rack.

You do not need to add additional racks to integrate the access network products GA, the switch module JRSU, and the integrated access module VSAN, VSAN plus, and other devices, both functions and performance achieve complementary results, so that modules and access network devices can truly achieve "value-added ".

Integrated and flexible product structure of access networks to improve device cost effectiveness

According to the user's demand for capacity and structure, the Blu-ray module provides a variety of different structural forms, such as the plug-board structure, 2U box structure and 1U box structure; their width is standard 19 ". You can choose to build it directly in 19 standard racks such as GA and VSAN plus, or through sub-racks, install it on the fifth sub-frame of S12, JRSU, or VSAN. In the access network, a large number of 2 MB businesses are usually increased and decreased on the parent board side, but only a small number of 2 MB businesses are increased and decreased on the Access Point side.

The blu-ray module combines the device structures of different structures and capacities in the same network to realize "big shoes" and "small shoes "; while meeting the actual needs of the network, the cost is greatly reduced, the cost-effectiveness of equipment is improved, and the market competitiveness of equipment is improved.

Access networks are integrated with powerful networking capabilities to meet the networking needs of different networks.

The blu-ray module has powerful networking capabilities and can form complex network topologies such as chain, ring, intersection ring, tangent ring, tree, Star, ring belt chain, and branch as needed. Its plug-board device unit can provide up to 12 STM-1/4 optical interfaces, expand the device networking capabilities. The cartridge unit can also provide multiple STM-1 or optical branch interfaces. The powerful networking capability can meet the networking requirements of various complex networks, reduce the number of devices, and improve the cost-effectiveness and market competitiveness of devices.

An integrated array of service interfaces for access networks to meet the needs of different users

Except for the common STM-1/4 group interface and 2 MB/34 MB/45 MB/140 MB/STM-1 branch interface, the blu-ray module can also provide RS232, V.24, V.35, 2/4 audio, and 10/100 MB Ethernet interfaces to meet the needs of different users.

For example, you can use the RS232 transparent interface to transmit network management information between BSC and BTS in the GSM network, which can meet the requirements of network management interfaces in the GSM network. Through the 10/100 MB Ethernet interface, you can directly provide IP Access. The rich business interfaces of the Blu-ray module can meet the needs of different users and be applied in different network environments.

Integrated Modular Design for access networks, easy to scale up and upgrade

The blu-ray module adopts an open modular hardware design structure. Modules can be combined to form different types of network elements, such as ADM, TM, REG, and DXC. Users only need to insert the corresponding module to complete the network expansion; when the device from the STM-1 to the STM-4 upgrade.

You do not need to change the entire device as long as you change the corresponding optical interface module. As the modules of the Blu-ray module are the same, the modules are easy to swap, which greatly improves the hardware usage efficiency and reduces the number of spare parts. Modular Design, easy resizing and upgrade, allowing users to invest in a single operation and achieve long-term benefits.

According to the existing network conditions and future network evolution trends, Shanghai Bell's integration of access networks is based on users' actual needs, the exchange node, which plays an absolute role in the communication network, provides a complete solution to gradually increase value, protect investment, and finally upgrade to a more competitive broadband multi-service interconnection network.
