Always On/Dynamic ISDN (AODI)

Always On/Dynamic ISDN (AODI) from BellSouth Business provides continuous low-cost network connectivity. This connectivity helps teleworkers avoid problems associated with repeatedly opening connections to a corporate network, including:

Downtime while connections are established
Inconvenience and interruptions to workflow
Possible failure to retrieve e-mail
Potential loss of sales or goodwill

ISDN (Integrated Services Digital Network) combines two circuit-switched B channels that can be combined to provide uncompressed data speeds of up to 128 Kbps and a packet-switched D channel (available with an ISDN Basic Rate Interface or BRI line). The D channel is the key to to the low-cost continuous connectivity offered by AODI. This service offers:

Security
Speed
Digital clarity
Flexibility
Expanded business voice services

AODI automatically switches network traffic to the channel that best supports it. The D-channel link, which is used whenever B channels are not required, provides a low-cost, continuous LAN-style connection for teleworkers, while employers don't have to sacrifice valuable circuit-switched ports on their networks to keep users continuously connected. When traffic increases one or both B channels are used for:

Retrieving e-mail attachments
Accessing the Internet
Downloading files
Other high-bandwidth tasks


		Sample Applications

		Feature-rich, real-time e-mail Advanced telecommuting Intranets, extranets, internetworking Internet access

		Features

		No dialing in to the network Reserves the D channel to send and receive e-mail Low-cost continuous LAN-style connection leaves B channels free for other calls. Provides uncompressed data speeds of up to 128 KBPS Automatically switches to one or both B channels for performing high-bandwidth tasks Enables users to switch to one or both B channels manually Automatically reverts to D-channel link when high-bandwidth traffic subsides

		Benefits

		Reduce costs. Lower the ISDN use rate on an employee line by using the D channel for continuous data connectivity at a substantially reduced rate. Streamline operations. Reduce the number of dial-in ports required on the corporate network. Increase efficiency. Provide teleworkers with access that rivals the LAN-based convenience enjoyed by office-bound colleagues. Increase productivity. Eliminate downtime associated with repeatedly dialing in to the network. Improve responsiveness. Notify employees as soon as they have e-mail. Maximize network resources. Provide continuous connections that stay up even while the ISDN line handles faxes, phone calls, and other data transfers. Improve communications. Colleagues and clients can rely on efficient e-mail communication, certain that employees receive all messages promptly. Make the most of network resources. Add or drop channels on demand.
