Oc1 And T1
It is important to know that if you want a good T1 connection there are a few things to know about digital signals and DS1 channels. If you group 28 DS1 channels together and you have a T1 or digital signal level 3 running at 44.736 Mbps, or 45 Mbps for short. Connect that to a wire circuit and its called a T1. This system was originally developed to provide high-speed trunk lines between telephone company offices.
It is based on DS0 or digital signal level zero, which is a 64K bit per second channel. Group 24 DS0 channels together and you have a DS1. Another aspect of the system is that if the DS1 is connected to a wire circuit, it is called a T1.
T1 runs at 1.544 Mbps. If your business class DSL or T1 broadband service no longer has enough speed to meet your bandwidth needs for video or data transfer, you may be considering a move up to T1 or T1 service. In addition, you can get an instant online quote if you will be so kind as to tell us where you want the service located, and provide some basic contact information so we can help you pick the optimum service for your business from available vendors in your area.
T1 is the big daddy of the T-carrier system. T1 is copper wire based, although using coaxial cable rather than pairs of phone wires to support the higher speed.OC-3 is another animal entirely.
Also, that T1 line is equivalent to 672 voice channels. T1 and T1 terms are used interchangeably. OC-1 service is the equivalent of T1 or T1. They provide 672 voice channels or telephone lines. They run at 52 Mbps to include the extra bits needed for the optical service.
The highest OC level you can get at present is OC-768, which runs at 39,512 Mbps or about 40 Gbps. If all you require is 2 or 3 times the speed of a T1 line, then you are better off with multiple T1 lines or connecting them together in what is called bonded T1 service. Once you get past 6 or 8 T1 lines, the price of a T1 line is often competitive. T1 transport may be a cost effective substitute for point to point microwave for MPEG Broadcast Video Transmission. It is also applicable for Surveillance Cameras, CCTV Systems, and VLAN Trunks.
If a full T1 line is more bandwidth than you really need, it is also possible to get Fractional T1, which gives you a portion of full T1 bandwidth at a lower cost. Of course, T1 is also available in multiples to increase bandwidth, similar to bonded T1 service. T1 Bandwidth generally makes sense for corporations that have a need for high speed electronic data transfer between plant sites or offices. Very large call centers, enterprise wide VoIP and IP PBX systems, Internet service providers, universities, research labs, video conference centers and software development companies are also good candidates for T1 lines with T1 level service. What is the difference between T1 and T1? Both of these terms originate in the T-carrier system.
