A little more on line terms…T1 aka Bell1 aka Digital Signal 0 or DS0 is an American standard, with 24 64k channels and a rate of 1.544k. E1-aka CEPT1 is the European standard with 30 64k channels and a rate of 2.048k, and J1 24 64K channels is the Japanese standard, same rate as US, but not compatible..line coding and framing is different.
