As-salam-o-Alikum!
Friends actually STM-1 contains 84 T1, because:
STM-1 contains 3x TUG3 (Tributary unit groups).
Each TUG3 contains 7x TUG2.
Each TUG2 contains 4x TU11
TU11 - contains VC11 and VC11contains T1 as payload.
Then 3x7x4=84 T1.

There are 28 T1 carrier lines in a T3 connection.
A T1 is copper, and OC3 is fiber optic, so there is no way to make a T1 into OC3. Speed on a T1 is 1.544 Mbps, and speed on the OC3 is 155.52 Mbps, so in rounding, you need 100 T1 lines to equal the speed of an OC3.
Cheap, high quality T1 lines can be found from stores such as T1Shopper and Telco Solutions. For consumers, most hotels provide T1 lines that can be used for Internet use.

WHAT IS SDH
A T1 line speed refers to the speed at which a T1 line is able to transfer data., often written in kilobytes per second. T1 lines these days see less use and have been replaced with fiber optics.
A OC48 is the equivalent of 1600 T1 lines or a little more than 56 T3 lines and can carry a total signal at 2488 megabits per second.
