Features

 Advanced IP+TDM Dual Bus Architecture:

To guarantee the best quality of all services provided, ZXA10 MSAN adopts advanced IP + TDM dual bus architecture, always using the most appropriate technology to process each kind of service based on its technical attributes. IP technology is the essential main force, dedicated to broadband based new-generation services, while TDM technology is a valuable supplement, since it will still be the best solution applications in near future.for legacy network applications in near future. For IP bus, ZXA10 MSAN supports GE to slot, which fully guarantees the maxim bandwidth requirement for each subscriber port of any kind of service card. Attribute to the ALL-IP core with adequate bandwidth, ZXA10 MSAN can easily integrate with the latest Ethernet based access technologies, i.e. ZXA10 supports new-generation broadband access services like VDSL2, and EPON etc.

Multiple Service Access Platform:

ZXA10 MSAN provides the integrated access of the narrowband and broadband services to satisfy the service access requirements for different users. All kinds of user cards can freely mix-insert at the same shelf.

High Service Processing Capability:

ZXA10 MSAN has powerful narrowband service and broadband service processing capabilities.

* Up to 48G non-blocked Ethernet switching capability to meet broadband service requirements

* Offering 16K*16K non-blocked TDM switching capability for TDM service at OLT side

* Offering 2K*2K non-blocked TDM switching capability for TDM service at ONU side

* Support 1024 multicast channels.

Service Aware Platform Based on QoS:

ZXA10 MSAN is a service aware platform which can provide different quality of service according to the requirements of the service. ZXA10 MSAN realizes perfect QoSmechanism for differentiated service.

* ZXA10 MSAN realizes end to end QoS procedure, such as traffic classification, traffic policy and metering, congestion avoidance, queue scheduling, traffic shaping etc.

* Provide different kinds of methods to differentiate service from terminals, it could be by multiple PVC, by 802.1P or by VLAN ID

* Support the isolation of control stream, narrowband media stream, internet stream and video stream in different VLAN or different physical uplink port.

Comprehensive Security Guarantee:

ZXA10 MSAN realizes security functions through the following aspects:

* Maintenance security which is used to limit operation right to prevent illegal activity,record any activities on configuration etc.

* L2/L3 mechanism implemented for security, which is described in detail in chapter 3.2.8.

* Networking reliability. security, such as uplink interface protection is used to improve.

Specification:
