Always On/Dynamic ISDN (AODI)
Always On/Dynamic ISDN (AODI) from AT&T Business provides continuous low-cost network connectivity
Always On/Dynamic ISDN (AODI) from AT&T 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
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.
