There are 3 DS3's in an OC3.
Generally an OC3 or higher capacity circuit will be used to deliver a DS3 due to distance limitations of the DS3.

An OC-12 has 4 x OC3. An OC3 has 2 x DS3. In total, there will be 12xDS3 in one OC12.
An OC12 has a capacity of 622.08 Mbps. This is the equivalent to having 12 DS3 lines. This is becoming a more popular choice for commercial bandwidth as demand increases.
An OC12 is the equivalent of 4 OC3's or 12 DS3's. A DS3 Breaks down to 28 T1's. Therefore there are 336 T1's on an OC3. If you go one step further there are 672 DS0's on a DS3 or 8064 DS0's on an OC12. a DS0 is a 64k Channel equal to a single POTS line. http://techblog.intelletrace.com/what-is-a-ds3-hub/
A DS3 is a telecommunications circuit capable of transmitting and receiving 45 Mbps at the same time. A DS3 is generally delivered using an OC3 or higher capacity circuit then is muxed out to a DS3. A DS3 hands off as two 75Ohm coax cables.DS3 Cable Type734 Cable = 450 Feet (137.2M) RG59 Cable = 340 Feet (103.6M) 735 Cable = 225 Feet (68.8M) You can order this type of service from Intelletrace.com 415-493-2200
DS3 is 44.7 Mbps and a T1 is 1.55 Mbps. So 1 DS3 = 28 T1s http://www.dslbroker.com/ds3.html
Point-to-point interfaces are used in serial communication. These types of connections are assumed to transmit solely to the station at the opposite end. The examples of Point-to-point are EIA/TIA 232, EIA/TIA 449, X.25, Frame Relay, T-carrier, and OC3 - OC192. simply: 1 source port to 1 destination port Point-to-multipoint connects one station to several other stations. Point-to-multipoint are of two types • Point-to-multipoint Non-Broadcast • Point-to-multipoint Broadcast In Point-to-multipoint Non-broadcast, the communication is replicated to all the remote stations. Only specific, selected stations hear the replicated communication. The examples are Frame Relay and ATM. simply: 1 source port to multiple destination ports

An OC3 breaks down to three DS3's. A DS3 Breaks down to 28 T1's. Therefore there are 84 T1's on an OC3. If you go one step further there are 672 DS0's on a DS3 or 2016 DS0's on an OC3. a DS0 is a 64k Channel equal to a single POTS line. http://techblog.intelletrace.com/what-is-a-ds3-hub/
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.
Stronger = faster? A T-3 is a DS3. The DS3 is 45Mbps. An OC3 is equivalent to 3 DS3's at 155Mbps http://www.intelletrace.com/internet-services/internet-services.html

how many DS3's are in an OC192
An OC12 is equal to 4 OC3 bandwidth connections.
3 ds3 in stm1
A DS3 has 28 T1's http://techblog.intelletrace.com/what-is-a-ds3-hub/
DS3 is 44.7 Mbps and a T1 is 1.55 Mbps. So 1 DS3 = 28 T1s http://www.dslbroker.com/ds3.html
an OC48 has 48 DS3's.
672 DS0 make 1 DS3
