A #T1 line is a communications transmission service that provides symmetrical bandwidth via 2 twisted copper wires. Businesses have long relied on telephone companies for this age-old service, which was originally developed for the Bell System. While standard telephone lines can only transfer voice and data at 56 kbps using a modem, a T1 line, can transmit data at a speed of 1.544 Mbps. T1 service for small business can be appropriate for high-speed data transmission, Internet access, voice, and video conferencing, depending on their type and configuration.
A T1 can be provided as a channelized or unchannelized service. In a channelized T1, the bandwidth is divided into 24 channels, with each channel having a capacity of 64 Kbps. 23 of these channels can be used to support 23 simultaneous voice calls. The 24th channel is used for signaling information such as caller ID.
An Integrated T1 is provisioned to handle voice and data traffic simultaneously. Some businesses utilize Integrated T1 lines for the convenience of having one provider. However, sharing the connection for both voice and data applications reduces the effective speed of the connection well below its full capacity since channels are allocated for either voice or data.
A Data T1 line, also known as T1 Internet, is an unchannelized T1 that is configured to transport data signals only. Its full capacity, 1.544 Mbps is used to carry Internet service, point-to-point data or VoIP (Voice over Internet Protocol).
For businesses that need bandwidth in excess of 1.544 Mbps, T1 lines can be bonded together to make them work as a single circuit. Two T1 lines, for instance can deliver 3.0 Mbps, four T1 lines deliver 6.0 Mbps, and so on.
So why are T1 lines so popular? Because T1 lines have been a stable business offering of phone companies for decades, T1s are a “comfortable” service. T1 pricing is about $250 per month per line, depending on your location and carrier. There are many T1 alternatives that provide comparably priced bandwidth that offer far greater performance and flexibility.
Consider the company that determines 5 Mbps is the right size bandwidth for its needs. Utlizing T1 lines, the IT manager can choose 4.5 Mbps (3 bonded T1s) or 6.0 Mbps (4 bonded T1s). Since companies typically prefer not to under-subscribe their bandwidth, most will get 4 bonded T1s, and pay extra for un-needed bandwidth. They will also need bonding equipment, such as a managed router for the Ethernet hand-off. Some carriers will provide this equipment, but quality may be less than desirable as they try to keep their costs down. It’s not uncommon for a port to go out, resulting in fewer operating T1 lines and less than desirable performance.
If you prefer more efficient and modern voice and data transport mediums with inherent flexibility to meet your needs, consider Fixed Wireless broadband. Skyriver Magnitude 5G class broadband and Skyriver Enterprise delivers business-grade Fixed Wireless broadband, with dedicated bandwidth to meet your specific bandwidth needs, without any extra equipment to pay for or worry about. Skyriver’s Ethernet hand-off can easily scale up to GigE in a matter of hours, not 30-45 days required from legacy T1 providers.
