Digital Networking
Intuity AUDIX Digital Networking is an optional feature package that provides customers with the ability to exchange messages with customers on other Intuity and AUDIX systems. The remote system can be collocated with or geographically distant from the local Intuity system.
Description
Intuity AUDIX Digital Networking uses the proprietary AUDIX digital protocol to exchange messages, subscriber profiles, and message status information with other machines. The digital protocol uses a digital file format, similar to a data file transfer between two computer systems, to transmit the information. Digitally transmitted messages are communicated quickly and with excellent sound quality.
Digital networking provides customers with the ability to exchange:
- Voice, fax, text messages, and attached files from networked sources, including:
- Messages from subscribers on other Intuity AUDIX systems
- Message Manager text components
- Networked Internet Messaging subscribers
- Voice and fax messages with customers on Intuity AUDIX R3 or later systems
- Voice messages with customers on Intuity AUDIX, Definity AUDIX R3.2 or later, and AUDIX R1V3 or later systems (AUDIX systems)
Requirements
All Intuity platforms support Intuity AUDIX Digital Networking. Intuity AUDIX Digital Networking requires the base platform configuration. The following table provides the base platform configuration.
Table: Intuity AUDIX Digital Networking Requirements
Capacities
The Intuity AUDIX Digital Networking feature supports a maximum of 485 remote machines. The system supports a maximum of 100,000 administered and nonadministered remote subscribers. The total number of networked systems and remote subscribers depends on the:
The Intuity AUDIX system provides a maximum capacity of 64 ports with 12 channels of digital networking. The following table summarizes the Intuity AUDIX system capacities for a system using digital networking.
Table: Intuity System Capacities with Digital Networking
Connectivity
The Intuity AUDIX Digital Networking feature package provides different types of network connections using the Digital Communication Protocol (DCP) or the Electronic Industries Association (EIA) RS-232 protocol or the TCP/IP protocol over an Ethernet connection to local and wide area TCP/IP networks. Data connections serve both local and remote networking, depending on the customer's system configuration.
Connection Types
The following table briefly describes the different types of network connections.
Table: Network Connections
Connection Use
The type of data connection used depends on the facilities of the site and how the customer plans to connect with remote sites. The customer does not have to use the same type of data connection for all networking channels. Each channel can have a different type of data connection. For example, a customer may dedicate channel 1 for a local stacking arrangement. A customer could use Channel 3 as an RS-232 channel for connecting to a remote machine that does not have a digital switch with DCP capabilities.
To use DCP mode 1, the Intuity AUDIX system must connect to a digital switch with DCP capabilities. These switches include the System 75, System 85, or DEFINITY Communication Systems Generic 1, 2, or 3.
To use DCP mode 3, the Intuity AUDIX system must connect to a digital switch with DCP capabilities, These switches include the System 75, System 85, or DEFINITY Communication Systems Generic 1, 2, or 3. Use DCP Mode 3 to create a stacked arrangement.
Use low-speed RS-232 connections when DCP switch facilities are not available or if a TCP/IP Intranet is unavailable.
Use either DCP (mode 1 or mode 3) or RS-232 to any Definity AUDIX R3.2 or AUDIX R1 system. These systems do not support TCP/IP networking.
Use TCP/IP to directly connect two or more machines when LAN/WAN facilities are available. The TCP/IP throughput is higher and more cost effective than DCP.
Channel Support
The Intuity AUDIX system allows combinations of DCP and RS-232 in two-channel increments through the ACCX circuit card. Each ACCX circuit card terminates four data channels in one of the following combinations. See Digital Networking Connectivity (DCP and RS-232).
- Two DCP ports, each providing two Interface channels (I-channels) for data. Depending on the version of the switch the customer has, only one of the two I-channels of each DCP port can be used as shown in the following list:
- System 75 R1V3, DEFINITY G1 R1V4, and DEFINITY G3i, G3s, or G3vs Version 1 only support one I-channel per DCP port
- DEFINITY G3i, G3s, and G3vs Version 2 can use both of the I-channels. The option must be purchased, installed, and administered on the switch before Intuity system administration is performed. Contact your account representative for more information on the I-channel option for the Intuity AUDIX Digital Networking feature package.
- Four RS-232 ports.
- One DCP port (two I-channels) and two RS-232 ports.
- When using TCP/IP, an ACCX card can take the place of up to four TCP/IP channels, through the Ethernet LAN card. If no ACCX card is used, then all 12 networking channels can be configured as TCP/IP.
The Sales and Design Support Center (SDSC) or the International Technical Assistance Center (ITAC) works with the customer to help determine the best configuration.
Features
Subscribers who want to send Intuity AUDIX Digital Networking messages to recipients on administered remote systems can:
- Address their messages by name.
- Include the names and telephone numbers of remote recipients in their personal mailing lists.
Note: Nonadministered remote recipients can be included only by telephone number.
- Hear the spoken name of the person to whom they are addressing mail or are looking up in the directory.
Note: If the administrator has not recorded these names or if the names have not been received in a remote update, subscribers hear only the remote mailbox ID.
- Use the names and number directory (
) to look up telephone numbers by name.
- Assign aliases to any remote recipients on systems administered for Intuity AUDIX Digital Networking. Administered remote recipients can be included by name or telephone number. Nonadministered remote recipients can be included by telephone number only.
- Use automatic addressing to reply to incoming messages.
Digital networking enhances AUDIX Messaging in these ways:
- Customers with business offices in more than one location, whether in the same building or in different cities, can exchange messages with all locations.
- Customers who exceed the capacity of one Intuity AUDIX system at a location can network multiple machines together to enable subscribers to exchange messages as if they were on the same machine.
The following message-exchange features can be used for messages exchanged between remote subscribers:
- The ability to address a message by entering a subscriber's name. This is called name addressing.
- The ability to play a recorded name, if a name is recorded for the remote subscriber, when a subscriber addresses a message to the remote subscriber or when the subscriber receives a message from the remote subscriber.
- The ability to forward messages to one subscriber or a group of subscribers, respond to messages, and create group mailing lists.
Note: Mailing lists cannot be shared across the network, unless the optional feature Enhanced List Application (ELA) is purchased. For more information on ELA, see System Features Description.
- The quality of the voice message received is the same as when it was recorded, no matter how many times the message is forwarded. This is true for voice messages exchanged between Intuity AUDIX systems and between Intuity AUDIX and DEFINITY AUDIX systems. Voice messages exchanged between Intuity AUDIX and AUDIX R1 systems use the AUDIX R1 voice messaging encoding. This type of encoding is not of as high a quality as that used by the Intuity AUDIX voice messaging system.
- Local and remote subscriber databases are updated automatically with the remote update feature.
- Customers with businesses that operate in different time zones can send or receive messages any time of day or night.
- All a digital networking subscriber needs to know to exchange messages with remote subscribers is the machine prefix and remote subscriber extension or, if using the name addressing feature, only the subscriber's name.
- Subscribers can exchange fax messages with Intuity AUDIX Release 3 and later systems that are enabled for fax.
- Subscribers can exchange text and/or file attachments with Intuity AUDIX Release 4 and later systems if both systems.
Operation
Before subscribers can exchange messages, the machine name, machine extension length, dial string, and starting and ending extensions must be administered for each machine.
Because an administrator sets up the Intuity AUDIX system with remote machine and subscriber information, all a subscriber needs to know to send a message to a remote subscriber is his or her name or machine prefix and extension.
Encoding Methods
The Intuity AUDIX system can accommodate messages encoded using the code-excited linear prediction (CELP) encoding algorithm or the subband algorithm. Because AUDIX utilizes only the sub-band algorithm, outgoing messages transmitted from a Intuity system to an AUDIX system are converted from CELP to sub-band format as they are sent to the remote system. Incoming messages are stored in the format received, either CELP or subband. Transcoding is made possible by the ACCX circuit card and the Intuity AUDIX Digital Networking feature package software.
The following table shows the encoding methods for the Intuity AUDIX Digital Networking package.
