Multi-Service Access Platform
MSAP-X3
Compact MSAP
MSAP-X3 is the compact Multi-Service Access Platform (MSAP) compatible with ITU-T standard. It is designed as a cost-effective and flexible multi-service platform, with STM-1 / STM-4 level uplink ports and abundant optional downlink cards to provide typical E1 traffic, PCM, optical tributary, EOS and EOP traffic access and aggregate.
As an important feature, in MSAP-X3, the SDH uplink module and Ethernet uplink module can work simultaneously. Between the SDH uplink module and each sub-slot, there are two STM-1 LVDS connections, and similarly, between the Ethernet uplink module and each sub-slot, there is one LVDS Gigabit Ethernet connection. With this backplane design, TDM traffic in SDH/MSTP network and packet traffic in IP network can be distributed and aggregated in MSAP-X3.
A powerful timeslot cross-connection and IP data switching facility is supplied in MSAP-X3. With the ability of connecting various network topologies, reliable self-healing mechanism, and unified intelligent management system, it is suitable for enterprise access, private network interconnection, mobile base stations connection and video monitoring applications.
