Inexpensive DS1 connection lines
A DS1 circuit is made up of twenty-four 8-bit channels (also known as time slots or DS0's), each channel being a 64 kilo bites per second DS0 multiplex pseudo-circuit. A DS1 is also a full-duplex circuit, meaning, in theory, the circuit can send 1.544 mega bites per second and receive 1.544 Mbit per second concurrently. A total of 1.536 mega bites per second of bandwidth is achieved by sampling each of the twenty-four 8-bit DS0's 8000 times per second. This sampling is referred to as 8-kilo hertz sampling. An additional 8 kilo bites per second is obtained from the placement of a framing bit, for a total of 1.544 Mbit/s, calculated as follows:
If a DS1 line is in your near future, take the guesswork out of your search and contact a broker. Brokers are able to contact numerous providers in the time it would take you to have a conversation with one or two providers that may not even offer service in your area. Want a line for under $500? Let your broker know this and he or she will know to point you only in the direction of such companies that offer a service at this price. We recommend the use of brokers in the search for service and we also recommend using a broker to sign up for your service. Many people believe they can "beat the system" by contacting a broker to get pricing and other information as quickly as possible and will then go straight to the carrier believing they can get better service. This "end-run" process is actually a good way to cut yourself out of some of the biggest advantages of having a broker. Brokers don't mark up the price of services. They offer the same price you would get if you did go direct to the company.
The advantage of ordering through a broker is that you will get a second channel of customer service. If the company is not performing to expectation you will always be able to go back to your broker who puts a significant volume through the carrier. A broker is much more likely to get the companies attention and have your problem solved. In our opinion, a broker is the only way to go.

DEDICATED BUSINESS CIRCUITS DS1 or ABOVE ONLY. (not for residential products, exception DSL)
DS-O (Digital Signal Level 0) - A non-switched dedicated service that can be provisioned as a private line point-to-point and multi-point service. This is designed for full duplex transmission of voice, analog data and digital signals transmitting at speeds of 56 KBPS. The circuit is BI-directional and can move information in both directions. Your home telephone line is a DS-0 line. You can get 56 KBPS of data or voice through your regular phone line. The DS-0 is the "building block" of dedicated products.
DS-1 (Digital Signal Level 1) - The terms "DS-1" and "T1" mean the same thing. Most industry experts are phasing out the use of the term T1 and calling it DS-1. A DS-1 is simply 24 DS-O circuits all bundled together on one T-1 circuit. DS-1 service provides a dedicated connection from the customer premises to a long distance switch, providing the user with a single high-capacity digital circuit for voice or data applications. With a DS-1, a customer has the choice of allocating all of the DS-0 channels for
data, voice, or any combination of the two.
T1 PRI Voice Service - T1 PRI Voice Service is exactly the same as T1 "regular" service, with 1 exception: only 23 channels are dedicated to voice or data. The last DS-0 channel is taken off to handle other applications, such as caller ID or a connection with the local telephone network or routing to a hold queue until 1 of the 23 channels opens up. Call Centers are the most frequent users of PRI Voice Service since they rely on the 24th line to provide caller ID.
Integrated T1 (Voice and Internet) Service - Integrated T1 service is just what the name implies: both voice and data traffic on the same T1. Since you have 24 channels (23 with PRI) to work with, you can divide up the load according to your customers need. For example, a company may have 10 phone lines. You can allocate 10 DS-0 lines for Voice, and 14 DS-0 lines for Internet.
Point to Point T1 Service - If you require constant connectivity to another office location, you should consider Point to Point T1 service. This is the same as regular T1 service, except now you have a Local Loop on 2 ends instead of just 1. This increases the cost of the monthly recurring local loop charge, but calls (or data transfer) between these two points is unlimited, with full duplex speed of T1 (1.5 MBPS).
Frame Relay Service - Frame Relay is for offices with 2 or more locations that require constant connectivity. Unlike Point-to-Point, the end-user can select sub-T1 speeds between each satellite location and the main office (or Host). This reduces cost and allows for future upgrades in speed on an as-needed basis.
Virtual Private Networks - Virtual Private Networks also known as VPN, are a much cheaper and in many cases more practical alternative to Frame Relay. Using a VPN, companies can network their computers together from remote locations using the regular internet. VPN technology will encrypt the communications between each location so that a high level of security is present, ensuring the privacy of the virtual network.
