T1 Carrier in Telecommunication

T1 carrier , which is also termed as DS1 , is a dedicated phone connection that supports the data at a rate of 1 .544 Mbits per second . The T-1 line usually consists of 24 individual channels with each line supporting 64Kbits per second . Therefore , the T-1 carrier can be configured to carry both data and voice traffic . Telephone companies commonly use it and Internet Service Providers (ISP ) to

provide both the data and voice services in the individual channels in what is termed as the fractional T-1 access . Bell Labs devised it in 1960s , and it was successful because it was able to support digitized voice transmission at that time . The term T1 is mostly used in Northern America and Japan while other countries refer to it has E1 . This means that the 24 channel can at times be referred as the T-span

In most cases , voice is usually send in terms of digital rather than the analogue that is produced by humans . Therefore , the channels that are associated with the digital carrier contains a digital connection device which is mostly termed has CSU /DSU - customer switching unit / digital switching unit . This device enables the carrier to be connected to four wires that are required to carry the information

Thus , the T1 carrier is digital and usually employs the pulse code modulation (PCM ) with the help...
