Internet Access - T1, DS3, OC3-OC48, Ethernet and Co-Location
Are all Internet service providers (ISPs) equal? Internet access technology may be similar, but you'll find big differences in network reliability, implementation, operations and customer care.

Evaluating Internet options for your business? Please Contact Us »

Business Class ADSL and SDSL
ADSL is appropriate for small office and home offices (SOHO.) ADSL (Asymmetric DSL) download speeds run up to 6-7 Mbps, but upload speeds are generally limited to 384-768 Kbps. Most often, ADSL shares a line with phone service. However, your location may qualify for dedicated line ADSL with a more robust service level agreement (SLA.)

SDSL (Symmetric DSL) has equal download and upload speeds up to 1.5 Mbps. SDSL is delivered over a dedicated line and includes a stronger Service Level Agreement (SLA). The consistent speed, dedicated line and SLA make SDSL more appropriate for mid-sized businesses.

Both ADSL and SDSL have strict distance limitations. If your address is more than 10,000 feet to a DSL-equipped Central Office (CO), chances are DSL may not be available.

Internet T1, Bonded NxT1, DS3 and OC3/OC12/OC48
Internet T1 service has 1.5 Mbps symmetric bandwidth, is delivered over dedicated 4-wire access, has no distance limitations and comes with a comprehensive Service Level Agreement (SLA). These features make T1 access a common choice for business Internet service.

A single Internet T1 has 24 DS0 channels, each with 64 Kbps bandwidth. Bandwidth from multiple channels is aggregated to deliver a Fractional T1 (4 channels = 256K,   6 channels = 384 Kbps, 8 channels = 512K, 12 channels = 768 Kbps) or a full T1 (24 channels = 1.544 Mbps.)

Multiple T1s can be combined or bonded into a single 'fat-pipe' using CEF, MLFR or MLPPP protocols running on customer and network edge routers. Most Internet service providers (ISPs) limit bonded T1 capacity to 4xT1 6.0 Mbps, 6xT1 9.0 Mbps or 8xT1 12.0 Mbps.

DS3 or T3 access can support up to a 45 Mbps Internet port delivered over co-axial or fiber cables. Fractional DS3’s are also available.  If you require more bandwidth, OC3 can support up to a 155 Mbps, OC12 can support up to 622 Mbps, and OC48 can support 2,488 Mbps. Any of the OCx options must be delivered over fiber facilities. Only available where the ISP point of presence (POP) is equipped for DS3 or OCx access.

Contact us and we will gladly show you prices from fractional T1 all the way up to OC48 Internet services.

Ethernet over Copper or Fiber
Ethernet over Copper uses traditional copper pairs to deliver Ethernet access and up to 1000 Mbps Internet port. Availability is limited to major metro areas, lit buildings or locations close-in to an Ethernet-equipped CO. Benefits of Ethernet access are lower overhead (vs. PPP or HDLC encapsulation),scalability, and lower cost. Network connection is via an RJ-45 Ethernet jack and a T1/DS3 DSU is not required.

Ethernet over fiber can provide Fast Ethernet (up to 1000 Mbps) or Gigabit Ethernet (1 Gbps) access. However, availability is limited to lit buildings with existing fiber facilities.


Co-location with DS3, OC3, Cat5E or GigE IP
If your application requires high bandwidth needs carrier diversity and can be remotely managed, then you may want to look at co-location or a managed service options.

Co-location provides secured, powered and environmentally controlled rack space, low cost Internet bandwidth and carrier diversity. However, servers are self-managed. You need to go on-site if you need to perform maintenance, upgrades or even reboot a server. Many co-location customers get facilities close-by their technical support teams.

Managed services is a step up from co-location, in both features and cost. Managed service or managed hosting providers supply and manage server, storage, firewall, operating system and database infrastructure. Services are located in major data centers, co-location facilities or carrier hotels. You get all of the environmental, bandwidth and diversity features of co-location, plus remote hands to manage servers.
