DS3 Equivalent to 28 T1 Lines
DS3 service at a signaling rate of 44.736 Mbps is the equivalent
of 28 T1 lines at their signaling rate of 1.544 Mbps. Because
of the strict synchronization of TDM services, 28 T1 lines may
be multiplexed into a single DS3 service.
Colocation is Often Cost Effective
Colocation is locating your servers in a colocation facility,
also known as a carrier hotel. Advantages of this approach include
ready availability of low cost bandwidth including DS3, Carrier
Ethernet and SONET Fiber Optic OCx options. These data centers
also offer backup power, environmental control and high levels
Applications Demanding DS3
DS3 transport is often used for real time video transport, high
resolution images, large engineering files, and data backups to
remote data centers. You can get this bandwidth through fiber
optic delivery or over copper coaxial lines, called T3 lines.
How Does DS3 differ from T3?
The terms DS3 and T3 are often used interchangeably. Both refer
to a TDM (Time Division Multiplexing) digital telecom service
operating at 45 Mbps. Strictly speaking, DS3 is the digital signal
level that can be carried by either copper or fiber physical links.
T3 is the T-Carrier standard for DS3 over coaxial copper service.
What is Fractional DS3 Service?
Fractional DS3, as the name implies, is a fraction of the full
DS3 bandwidth of 45 Mbps. Companies order fractional DS3 when
they don't need or want to pay for the full bandwidth offered
by DS3. Even with fractional DS3, you still need the full coaxial
or optical hardware support for 45 Mbps signaling. At low fractional
requirements, bonded T1 lines offer a more cost effective solution.
