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.
When to Use Pseudowires
A pseudowire is a virtual "circuit" that emulates a
traditional digital telecom service but on a packet switched network.
MPLS networks are especially suitable for pseudowires. By using
a pseudowire circuit, you can get the point to point connectivity
you desire without having to re-engineer your facilities to accommodate
a different protocol network.
Dedicated DS3 Internet Access
Business broadband via DS3 dedicated Internet service offers 45
Mbps of upload and download capability. That's enough to support
a medium size or larger office, including file transfers, email
and Web browsing, video conferencing and real-time ecommerce activities.
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.
Difference Between DSL and
DSL means Digital Subscriber Line and is a shared bandwidth service
offered on a "best effort" basis by telephone companies.
DS3 is a professional telecom service with a fixed bandwidth of
45 Mbps both upload and download. DS3 is usually sold with on
a contract with a service level agreement.
