: I heard them talking about there T1's and T2's
: T1's and T2's are a bundel phone lines tied together for incoming or out going info ether voice or data.
: T1's have 26 pair and T2's have twice that.

- That's logical capacity. T1 is actually a bandwidth spec (as described by 6P21), regardless of the medium (wire, fiber, microwave, etc.). A typical telco-leased T1 will be carried over 2 pairs of copper ("4-wire circuit") and will be terminated by a Channel-Bank, CSU/DSU, or other mux/demux equipment depending on how the circuit is being used.
