Position: ZTE MSAN Solution Help Build Flexible and Multi-play Service Network
Requirements
Facing increased competition from wireless telecommunication operators, providers of cable television networks and large Internet content providers with strong brands and deep pockets, the fixed-line operators are now searching for new revenue streams from the increasingly popular triple or quadruple play bundled package of IPTV, voice calls and ultra-high-speed broadband Internet access. Telecom field has entered the period of transition with the theme of convergence. Convergence is also ongoing at the access layer. One integrated access platform for all kinds of access can realize unified plan, unified construction, unified service provision and unified maintenance so that it will greatly decrease both CapEx and OpEx.
ZTE’s Flexible MSAN Solution
-
Network Solution
The MSAN can be used in different network scenarios.
ZTE’S MSAN solution for PSTN&NGN
For the TDM voice service, The MSAN connects to PSTN network via V5 interface. The access network structure can be a traditional optical line terminal (OLT)-optical network unit (ONU) link or an ONU with a direct connection to the PSTN. In the OLT-ONU structure, the built-in MSTP will be used for service transmission and the ONU can be deployed anywhere to realize FTTx because of the flexible networking capability of the built-in MSTP.
To provide NGN IP-based voice services, voice is converted from TDM to IP format at the MSAN. ZTE provides ZXMSG5200/ZXMSG5600 access gateway products to meet different capacity requirements. ZXMSG5200 is a medium capacity AG. ZXMSG5600 is a large capacity AG. It can be used for local subscriber’s access and remote access through built-in MSTP to extend NGN to regions where the metro network has no coverage yet.
- Migration Solution from PSTN to NGN&IMS
ZTE’s MSAN can be smoothly migrated from the access equipment used in PSTN to the access gateway used in NGN and IMS, to keep up with evolution requirements while protecting operators’ existing investments.
Both the OLT and ONU can be upgraded to an access gateway.
MSAN upgraded to access gateway
The upgrade of an OLT to a ZXMSG5600 access gateway is very simple. VoIP media processing cards need to be added to realize TDM-to-IP voice conversion; the software of main control cards needs to be upgraded to implement H.248/MGCP and to realize connection with NGN. As the OLT upgrade solution does not need to change any of the hardware or software of ONU nodes, it requires less workload and has less impact on the network.
An ONU can also be easily upgraded to a ZXMSG5200 in the same way as an OLT upgrade. Compared with the OLT upgrade solution, the ONU upgrade solution can realize end-to-end VoIP, simplifying the network structure.
Operators can choose OLT or ONU upgrade solution according to their own situation.
Customer Benefits
Aggregating multiple technologies into a single platform, the solution enables operators to glide from traditional service to triple-play services over a variety of access technologies. and to remain competitive in the period of convergence and evolution of the world of communications. ZTE MSAN can bring following benefits to customers:
- Access layer convergence to decrease TCO
One integrated access platform for all kinds of access can realize unified plan, unified construction, unified service provision and unified maintenance so that it will greatly decrease both the CapEx and the OpEx, compared with solution of dedicated device for each service access. - Smooth evolution to save investment
The MSAN supports smooth migration from PSTN to NGN and IMS to protect the operator’s investment. Both OLT and ONU in the PSTN network can migrate to access gateway in the NGN/IMS network. - Bandwidth expansion to enhance multimedia experience to attract broadband users
The emergence of multimedia services, including VoD, network gaming and IPTV, puts high requirements on the broadband bandwidth. ZTE MSAN’s VDSL2 & EPON/GPON access expands bandwidth to enhance user’s multimedia service experience to attract more broadband users. - Traditional service inherits to guarantee the operator’s revenue
Though the income from traditional service is decreasing, it is still an important revenue source for the fixed operator. ZTE MSAN is an integrated platform which has good compatibility with traditional service like POTS, ISDN, DDN etc. Besides, the MSAN supports PWE3 function to help operators inherit TDM leased line service in a modern all-IP network environment.
