| Planning for ELA Implementation
ELA is a powerful messaging tool that can distribute large quantities of messages. Review the following considerations to ensure effective implementation and use of ELA: What you need before you begin Administering the INTUITY system for ELA Administering ELA for INTUITY Scheduling ELA Message Delivery Local Area Networks Remote messages Port usage Shadow mailbox ### What You Need Before You Begin Before you begin to implement ELA on the INTUITY system, you must have the following information available: An available Class of Service (COS) number. This COS number is used by ELA for list mailboxes and the shadow mailbox. If possible, COS 8 is recommended. A community ID for the shadow mailbox. Ideally, the shadow mailbox, as well as the shadow mailboxes of other networked machines, is the only occupant of the selected community. If possible, community 11 is recommended. A community ID for the ELA list mailboxes. All of the list mailboxes need to reside in the same community. This community cannot be the same number as the shadow mailbox community. If possible, community 10 is recommended. A range of extensions to place list mailboxes. You do not need this to set up ELA but you will need to provide extensions for the list mailboxes when you begin creating lists. ### Administering the INTUITY System for ELA The tasks involved with administering the INTUITY system for ELA are listed below and described in detail in Administering INTUITY AUDIX for ELA. The following steps are required to administer the ELA trusted server and functionality for INTUITY AUDIX: Increase the number of mailing lists that INTUITY AUDIX allows on the system. Define an ELA Class of Service. Set up ELA and shadow mailbox Community IDs. Create a shadow mailbox. Administer TCP/IP LAN connectivity if it is not already administered. ### Administering ELA for INTUITY AUDIX The tasks involved with administering ELA for INTUITY AUDIX are listed below and described in detail in Administering ELA for INTUITY AUDIX. To make ELA fully functional, you must: Configure ELA. Create enhanced lists. Add members to enhanced lists. Record a name for the enhanced lists (optional). Test the enhanced list setup. ### Scheduling ELA Message Delivery It is recommended that you schedule delivery for large enhanced lists during off-peak hours. This is because during peak traffic hours, your system processes other subscriber-generated messages. ELA intentionally slows delivery of messages to large enhanced lists during peak traffic so your system can continue to process these other messages. ### Local Area Networks If your configuration includes a local area network, involve your PC/LAN administrators in the ELA implementation to ensure that INTUITY AUDIX and the network are not adversely affected. The amount of traffic on your LAN from ELA messages could increase if ELA sends messages for delivery to email or Message Manager recipients or to TCP/IP-networked remote machines. If none of these are valid for your site, ELA will not cause any increase in LAN traffic. ### Remote Messages If your site is networked, estimate the increase in the amount of remote traffic by determining the percentage of current traffic that is remote and by calculating the number of messages per minute that percentage represents. When ELA is actively sending messages, add that number of messages to the traffic estimate for remote message delivery. ### Port Usage Voice port usage increases as recipients retrieve messages sent by ELA. Plan for the increase with Professional Services when you purchase ELA. After installation, monitor your system to determine if your Grade of Service (GOS) falls below acceptable levels. If that happens frequently, particularly during the peak busy hour, contact your account representative to purchase more ports. ### Shadow Mailbox The shadow mailbox is a special mailbox that ELA uses to distribute messages. The use of a shadow mailbox prevents replies to ELA-delivered messages from being sent back to the entire enhanced list. However, you can administer enhanced lists so that recipients can reply to the person who originally sent the message. The shadow mailbox must belong to a community that cannot receive messages.
