DS3 vs Multiple T1 Lines
Bonding T1 lines for greater bandwidth is a good value up to about
8x or 9x bonding. Above that, it makes better economic sense to
order DS3 service over fiber or T3 copper line. In metropolitan
areas with high levels of buildout, the decision point may be
less than 8 T1 lines.
Medical Imaging Transmission
Medical images, such as those generated by Teleradiology equipment,
have large file sizes due to high resolution. Rapid transmission
between hospitals and medical centers requires high availability,
high bandwidth telecommunication services. For smaller offices
or infrequent use, a T1 data line or bonded T1 lines might suffice.
For medium and larger facilities, DS3, Fast Ethernet and OCx fiber
optic services are recommended.
DS3 for Call Center Telephony
DS3 voice service can support up to 672 simultaneous telephone
conversations without blocking. If your call center or large corporate
PBX system requires this number of outside lines, DS3 is likely
far more cost effective than ordering the equivalent 28 T1 lines.
What is the T-Carrier System?
T-Carrier is a set of standards developed by the Bell Telephone
Companies back in the 1950s. These include T1 and T3 lines. They
also define digital signal levels such as DS0, DS1 and DS3. DS0
is 64 Kbps, DS1 is 1.5 Mbps and DS3 is 45 Mbps.
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.
