T3-DS3 Applications
T3 is a relatively large data bandwidth pipe which is commonly used for internet connectivity, voice lines, direct point-to-point connection between two business locations, Multiprotocol Label Switching (MPLS) networking between multiple locations of a business and integrated circuits which combine any combinations of these applications.
T3-DS3 Internet
A T3 data circuit can support up to 600 internet users, depending on application and simultaneous usage. DS3 is also great for facilitating servers which will allow hundreds of simultaneous users to access information from servers.
T3-DS3 Voice
A DS3 voice circuit is excellent for large call centers, or for facilitating the telephone needs of hundreds of occupants of an office complex. T3 voice can be provided either as local voice, for local and long distance calling, or as long distance voice, which provides wholesale per minute long distance prices but does not facilitate local calling. Both long distance and local voice can be integrated into one DS3 voice circuit.
T3-DS3 Private Point-to-Point
DS3 point-to-point circuits are extremely popular for connected two or more business locations. To clarify, with point-to-point a separate circuit is needed for each two locations networked. These circuits can facilitate location to location transfer of large data files, multiple file transfers between hundreds of employees, location-to-location voice traffic and video conferencing.
T3-DS3 MPLS Networking
DS3 MPLS networks are better suited for networking more than two locations than point-to-point circuits. This is because MPLS facilitates any-to-any location networking rather than requiring a separate circuit for each two locations required by point-to-point networks. Also, with Class of Service (CoS) MPLS can prioritize applications. With CoS, applications such as routine data transfer, voice, and video can be efficiently implemented simultaneously over one bandwidth pipe, without interfering with each other. MPLS is a major advancement when compared networks based on point-to-point or frame relay.
T3-DS3 Integrated
One T3-DS3 integrated circuit can accommodate all applications mentioned above on one circuit. For example, with an integrated DS3 circuit, local voice, long distance voice, video, internet and networking can all be facilitated on one circuit.
T3-DS3 and the Need for Build-Out
DS3 requires fiber or other forms of special wiring to reach each business location. This is very important because new customers, or customers considering upgrading from t1, bonded t1, or ethernet over copper, must pay for this wiring (build-out cost) before their building can receive t3 or OC circuits. Buildings which are connected to fiber, and therefore able to receive DS3 are referred to as being “lit”. It is not uncommon for customers to fail to plan for this unexpected upfront cost when planning the installation of DS3. Build-out often costs tens of thousands of dollars.
Alternatives to T3-DS3
There are many alternatives for customers who need less or more bandwidth than can be provided by DS3. If a customer needs between 15 mbps and 35 mbps, then fractional T3 is an excellent choice. If 12 mbps or less are needed, then ethernet or bonded t1 are excellent alternatives. It is important to consider these alternatives if less that 45 mbps are needed because bonded t1, and ethernet are delivered over copper phone lines and therefore do not require expensive build-out costs. Often bonded t1 and ethernet are installed for free. If more than 45 mbps is needed, then OC 3 (155 mbps) is a good alternative. Both fractional DS3 and OC circuits require build-out for buildings which are not lit.
Ethernet over T3-DS3
Larger ethernet circuits can be delivered over DS3. There are at least three advantages of ethernet over DS3. First, ethernet over DS3 can deliver higher bandwidth than a regular DS3 circuit. Ethernet over DS3 can provide up to 88 mbps. Second, ethernet over DS3 can be less expensive per mbps then DS3. An 88 mbps ethernet over DS3 circuit can often be offered for less than $6000 per circuit. Depending on location, $6000 is the average cost for a 45 mbps DS3 circuit. Third, ethernet over DS3 requires much simpler and less expensive hardware for handoff at the customer premise than does DS3.
