Multi-Service Access Platform
MSAP-X7
Compact MSAP
MSAP-X7 is the centralized 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/STM-16 level uplink ports and abundant optional downlink cards to provide typical E1 traffic, PCM, optical tributary, EoSDH and EoPDH traffic access and aggregate.
As an important feature, in MSAP-X7, the dual SDH uplink modules and dual Ethernet uplink modules can work simultaneously. Between each SDH uplink module and each sub-slot, there are STM-1 LVDS connections, and similarly, between each Ethernet uplink module and each sub-slot, there are LVDS Gigabit Ethernet connections. With this backplane design, TDM traffic in SDH/MSTP network and packet traffic in IP network can be distributed and aggregated in MSAP-X7.
A powerful timeslot cross-connection and IP data switching facility is supplied in MSAP-X7. 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.
