24 DS0 make 1 DS1 28 DS1 make 1 DS3 672 DS0 make 1 DS3
672 DS0 make 1 DS3
three if the question was How many 1/3 make a whole
how many rows can you make with 169
I think you mean HOW many tens make 900, so the answer is 90

A DS1 is a telecommunications standard used in North America, Japan, South Korea and some Pacific islands and territories. The term stands for 'Digital Signal [level] 1.' A T1 is the actual 4-wire circuit used to transport the DS1 signal, and the two terms are often used interchangeably. A DS1 signal is part of the [North American] Time-Division Multiplexing heirarchy, and operates at a speed of 1.544 Mbps (Megabits per second), including 8 kbps (kilobits per second) of framing bits. The signal is comprised of 24 timeslots of 64 kbps DS0 (DS-'zero') channels. The DS0 is the most basic unit of the TDM heirarchy, and can be considered the equivalent of a regular voice phone line (56 kbps + 8 kbps of signalling) or a digital line (of 64 kbps), so a DS1 can be said to contain the equivalent of 24 phone lines on one 4-wire circuit. The T1 circuit uses a separate transmit pair (2 wires) and a receive pair (2 wires) and operates at the effective speed of 1.544 Mbps in both directions simultaneously.

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/
up to 670 (voice). If its t1, then only 28.

A DS1 pedal is a device that guitar players press down on with their foot. When they do this their guitar makes distorted noises and other sound effects.
There are 2 well known DS1 definitions so depending on which one you're talking about will determine the age, so the most popular will be addressed below. The first DS1 otherwise known as Digital Signal 1 or T1 was developed around 1960 by Bell Labs which is a telecommunications circuit. The second DS1 term is Deep Space 1 which is a NASA satellite that was launched from Cape Canaveral on 10/24/1998.
