Grande Enterprise: Data

Grande offers a suite of service options that deliver premium networking power to the enterprise marketplace, including Internet access, multi location metro networks, intercity private data networks and metro Ethernet via our extensive fiber network.


Grande brings your enterprise high-speed Internet access at an affordable price. Our all-digital network allows for speeds from 1.544 Mbps T-1 up to Gigabit over traditional access methods or Ethernet.


Whether your business requires storage network access, disaster recovery backup, VoIP between company offices, or large file transfers, Grande offers the services you need, including Ethernet wide area network (W-A-N) services that connect your corporate local area networks (LANs). By leveraging the open Ethernet standards that IT managers trust, (i.e. native Ethernet) you will be armed with an efficient and cost-effective solution that requires no new training or equipment. Our metro Ethernet connection brings versatility that allows additional bandwidth to be provisioned quickly and transparently in one, five and ten megabit increments.


Utilizing the latest in 100 Mbps, 1 Gbps, and 10 Gbps optical Ethernet technologies, Grande's Metropolitan Area Network (GMAN) takes your data service to a whole new level of performance and reliability. With GMAN your data connections can take advantage of true "wired speeds". No more bonding of TDM circuits, fragmentation of transport packets, or fighting PPPOE. Combining the power of fiber optics, the simplicity of switching and the cost efficiency of IP transport, this metro Ethernet network is ideally suited to delivering the full range of data services to your location. Whether it's the readily scalable dedicated Internet access (DIA), the simplicity of layer 2 transparent LAN service (TLS), the ultra low latency for voice over IP applications or the highly reliable packet delivery for video over IP, GMAN gives your business the competitive edge for an efficient, low price.


GMAN 100

100 Mbps FX switched Ethernet connection, single link and route, offering efficient, scalable bandwidth options for DIA, TLS services and optional enhanced business lines/trunks for voice services. Customer data interfaces are RJ-45 10/100 BT, full or half duplex.

GMAN 1000

1 Gig Ethernet switched Ethernet connection, single or multiple links and/or routes, offering large quantities of scalable bandwidth options for DIA and TLS services. Customer data interface may be user-defined with the default being RJ-45 10/100/1000 BT, full duplex, auto negotiate.



Non-blocking, continuous symmetrical layer 3 Internet access via a unique /29 subnet connection network between Grande's CORE router and a customer owned router, firewall or NAT device. Additional static IP addresses available upon request as a routed block to the connection block.


Non-blocking, continuous symmetrical layer 2 VLAN bridging between multiple GMAN or GDDC locations. TLS port accepts full 1500 byte MTU plus any optional customer controlled VLAN TAG, also known as Q-in-Q.


Business lines delivered over a data connection and converted into a single-pair, loop start line directly into an analog telephone or key phone system.


Business trunks delivered over a data connection and inserted directly into customer private branch exchange (PBX) or IP-PBX switch.


Ethernet has emerged as the leading technology to support IP traffic for packet optimization. No alternative provides the balance of high-performance, economics, manageability and flexibility found in a packet networking solution. Today's transport SONET/SDH-based networks are incapable of handling those capacitates, and layer 3-centric, distributed-IP router approaches are too expensive to use only for transport and aggregation when routing is not necessary.

Ethernet has emerged as the leading technology on which many next-generation networks will be based, for economic and scalable transport and delivery of fast-growing, high-bandwidth, IP-based applications. An IP router at an end-office is used primarily for aggregations, a function an Ethernet switch can perform more cost-effectively. Integrating fully featured Ethernet aggregations and switching in the metro transport system simplifies the IP/Ethernet service architecture, lowering Total Cost of Ownership (TCO) 30 to 9 percent compared to alternative metro solutions.
