Access Multiplexer: Metroplex 6000

ACCESS MULTIPLEXERS

	Service provider termination of voice and data using T1, E1, or HDSL on the customer premises
	Point-to-point T1/E1/HDSL multiplexing over private facilities with the added benefit of consolidated voice, data, and video from an H.320 codec
	Interfaces with ATM switches for cost effective delivery of full and fractional T1/E1/HDSL services via an ATM backbone network.

METROPLEX 6000

	Organizes remote office voice along with data and video traffic
	Provides increased aggregate flexibility via two independent network interfaces
	Fits the limited space available in the remote site's wiring closet
	Brings HDSL (High bit rate Digital Subscriber Line) onto the customer premises
	Dual T1, E1, HDSL or DSX-1 service access
	Modular, scalable architecture reduces equipment investment and field repair time
	Supports a variety of both voice and data channel interfaces on one platform
	Provides VT-100 local management craft port control plus Telnet or SNMP management, plus dial-out on alarm

Bandwidth Manager-TMS-OCM

GDC's TMS-3000 Advanced Internetworking Platform offers superior bandwidth management for high speed wide area networks. The Multi-nodal, Multi-aggregate architecture of the TMS-3000 enables service providers and enterprise users to build fully mesh, fault tolerant resilient backbone networks. Cost effective access to smaller branch or regional offices is supported through the OCM-2000 feeder platform. TMS-3000 is ideally suited to accommodate and efficiently transport a changing mix of applications, LAN to WAN integration, image and video along with traditional voice and data services.

TMS-3000 allows users to accomplish virtually any networking objective efficiently and economically. Complete flexibility provides for ease of upgrade to accommodate future requirements.

TMS-3000 Highlights

 

	Global digital connectivity - narrowband, wideband, fractional and hybrid access
	Branch office traffic consolidation - Voice, video, and data traffic over economical T1/E1, Fractional T1/E1, or narrow band facilities
	Flexible network topology and system configurations- point-to-point, delta, mesh or star
	Configuration as a T1/E1 time slot interexchange switch, LAN bridge, or frame relay switch. Concentrates LAN traffic from hundreds of remote locations
	Versatile frame relay support - public and private applications and full frame relay standards support
	Extensive voice compression options - CELP, ADPCM, digital PBX T1/E1 voice channels
	Comprehensive data traffic options - T1/E1, fractional T1/E1, 56/64 Kbps; SNA, HDLC, SDLC, frame relay
	Software downloading for non-disruptive updates
	Simplified circuit management including automatic route optimization, intelligent automatic reroute feature, and off-line network modeling
	Graphically network management interface

OCM-1000/2000-Office Communications Manager

The OCM-1000 and the OCM-2000 are powerful, cost-effective TDM networking platforms. The OCM-1000 provides point-to-point and point-to-multipoint connectivity to small and medium sized branch sites. The OCM-2000 extends the TMS-3000 backbone network's capabilities to remote branch office locations. Both OCM platforms offer connectivity to a variety of digital carrier services, allowing users to select the one with the best performance/cost ratio in each location. They use the same bandwidth optimization techniques as the TMS-3000 to efficiently transport voice and data traffic.

OCM Highlights

• Support for a variety of digital services ensures easy implementation of global networks
• Integration of both traditional voice and data and LAN to WAN internetworking, video conferencing and imaging over common digital facilities
• Multi-aggregate capability for resilient mesh networks with diverse routing options
• Configuration and management from a single central-site platform
• Exceptionally high quality voice compression options
• Easy migration path from OCM-1000 to OCM-2000

Network Management

The TMS-4000 is a SPARC Platform based, centrally weighted Network Management System (NMS) designed to exceed the current standards for network management and meet the needs of both public services providers and enterprise networks. Operating under HP Openview, the TMS-4000 offers full graphical representation of up to 256 TMS-3000 and 10,000 OCM-2000 nodes in a single domain. The TMS-4000 "point and click" and "drag and drop" functionality makes network configuration, maintenance and control intuitive and easy. The TMS-4000 also allows for the creation and management of Virtual Private Network (VPN) partitioning, for the development of independent "sub-networks". The TMS-4000 supports Common Management Interface Protocol (CMIP) for communications to higher level management systems, and is compliant with the ITU-T Telecommunications Managed Network (TMN) standard.

In small to medium sized TMS-3000 backbone networks, the P.C. based GDC TMS Software (GTS) application provides network configuration, control and management to TMS-3000 and OCM- 2000 nodes. In point-to-point and point-to-multipoint OCM-1000 networks, the P.C. based are OCM Management System (OMS) can be utilized. Both systems provide configuration, alarm reporting, diagnostics and centralized system management. Simple , pop-up windows and mouse or keyboard commands make GTS and OMS user-friendly, while providing comprehensive functionality.
