Overview

Reliable and fast communication is vital for continuous operation of power delivery systems and mission-critical operational services. For many years now, telecommunication networks have been undergoing significant changes. Increased bandwidth requirements and a large variety of services to be transported have led to much more versatile but also complex access and transmission equipment, adapted for the next generation of networks. Gridcom DXC/eDXC/DXC-S is more than a conventional access and transmission platform, and is based on a modular and evolutive configuration platform. The range of Gridcom DXC/eDXC interfaces cover all needs from conventional (FXO, FXS, 2/4W E&M, RS232, V.35, V.36, X.21, RS485, 64 k G.703) to more sophisticated configurations oriented toward new data network architectures such as Ethernet, IP and MPLS-TP. Gridcom DXC/eDXC also includes a standard C37.94 interface to interconnect protection and teleprotection devices through optical fibre, G.703 Co-directional and 1/0 dry contact alarms.

Ready for Future Network • Cost effective solution • High quality of service • Very high modularity • High level of reliability via full redundancy • SNMP management • High board density • IEC 61850 compatible • Optical interfaces • Ethernet switching • IP routing functions • TDMoIP for multiplexing on native Gigabit Ethernet • Tested for harsh substation environments • 10G interfaces • MPLS-TP

Fulfilling Utility Requirements GE offers a new generation of robust and reliable access and transmission multiplexers: • Access cross-connect Gridcom DXC (PDH) • Enhanced Digital cross-connect Gridcom eDXC (PDH/SDH/MPLS-TP) • Transport cross-connect Gridcom DXC-S (SDH/MPLS-TP) The Gridcom DXC/eDXC offers generic slots capable of supporting such interfaces as E1/T1, Ethernet 10/100Mb compatible with IEC 61850, xDSL, G.703, RS232, V35, RS422, RS285, X21, 2/4W E&M, FXO, FXS, Terminal Server, C37.94, as well as short- and long-haul optical interfaces. All vital parts, such as the power supply and the processing board can also be 1+1 protected. The Gridcom eDXC/DXC-S provides enhanced capacities on transmission STM 1/4/16, MPLS-TP, Gigabit Ethernet, 10 Gigabit Ethernet connectivity and Gridcom eDXC supports all PDH boards available on Gridcom DXC equipment.

Reliability/ Availability By concept and design, Gridcom DXC/eDXC/DXC-S is a cost effective solution to match a high level of availability and harsh environmental constraints. It offers a modular approach in terms of protection mechanisms like controller redundancy, shared power supply units as well as 1+1 protection for the 2Mbit/s and optical interfaces, providing a suitable solution to critical applications.

Powerful Management System • Different management solutions are available, answering to different network complexities and customer maintenance organizations for remote configuration and management: • Gridcom iNET: Element Management Layer, this solution responds to a centralized monitoring of equipment with Graphical User Interface (GUI). • Gridcom INMS: Network Management Layer is the right solution to fully operate a complex network. In addition to all conventional features usually proposed for the backbone level (Security, graphical user interface, statistics, etc), INMS includes versatile tools for automatic path creation and configuration of equipment simply by a simple “mouse click.” • High-availability schemes are available for both Gridcom iNET and INMS. • All equipment are SNMP native and offer direct compatibility with the GE telecom management system Sentinel.
