Digital Data Service: Digital Data Service (DDS) offers you a dedicated connection between two or more sites. The connection is permanent and available at all times. DDS handles data, voice and video at different speeds. With DDS you can: Improve efficiency by reducing delays, errors and connection times. Say no to plagiarism.

Features and Benefits: Offers DDS to end-user customers in service increments of less than 64 kbps - allowing you to purchase only as much bandwidth as you need. Eliminates need for modem (use channel service unit/data service unit - CSU/DSU - instead) - reduces modem expenses. It offers the reliability and quality of digital transmission - saving time by eliminating delays and reducing errors caused by distortion common to analog transmissions. The circuit can be used for data, voice and video - consolidates communications onto a single circuit, reducing maintenance costs. Available at any time because the connection is dedicated: improves efficiency by eliminating delays and connection times. Digital Data Service (DDS) is a dedicated link between two or more sites and offers flexibility in bandwidth. It can host a wide variety of voice, data, video and interactive applications. Any service provider and end customer who needs low speed, high accuracy and guaranteed availability will benefit from DDS. A digital data access channel is a channel for a four-wire duplex transmission of 2.4, 4.8, 9.6, 19.2, 38.4, 56, or 64 Kbps. You select the actual bit rate by choosing which combination of protocols to use. The channel provides synchronous service with the timing delivered through your facilities to the end customer in the received bit stream. Digital transmission provides more accurate signals than analogue, mainly due to signal regeneration. Data amplification involves transmitting data when the end customer is beyond the normal 42 decibel (dB) loss range for digital data service (56.0 kbps and 64.0 kbps). The loss in dB is determined by the route, length and thickness of the cable from the last reporting point (usually the switching office) to the end customer location. Optional DDS features and functions include central office bridging, secondary channel and data amplification. Please note: this is just an example.

DDS can connect multiple sites for frequent transmission of low-speed data, such as payroll and accounting information, shipping, reservations, and inventory control. DDS can be used to access a Frame Relay network. DDS is ideal for remote monitoring of systems for security purposes.
