RE: T3- DS3

[JL]

a T-3 is equal to 28 T-1's. Your question prompted some interesting reading.   From the McGraw Hill "Voice and Data Communications handbook": A T1 is the first level of T-carrier system. A DS1 is the multiplexed digital signal, first level, inside the T-carrier.   From the Lan Times "Encyclopedia of Networking": Digital Signal (DS) refers to the rate and the format of digital telecommunications circuits. DS is related to the T designations, but DS refers to signal rates and formatting while T designations are usually applied to equipment.   So, from what I have read the main difference is what the name is being applied to and not much more. I would be interested in what others on the list have to say though and I will inquire with the engineers I work with for their take on the differences this evening while at work.   Gragg Vaill MCP CCNA NOS Contractor Sprint ION NOC Kansas City, Ks. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Chris Larson Sent: Tuesday, November 21, 2000 7:04 AM To: [EMAIL PROTECTED] Subject: T3- DS3 What is the difference between the 2. I know a T-3 is the about equal to 30 T-1's, but there must also be a difference in signaling right?
