Deletion of Avaya ERS 4000

Comment: to an article about this product line, but  keep a substantial amount of the basic content.   Anyone urging an outright delete, should explain why a merge isn't suitable, because according to eletion Policy, merges are preferred to deletions.   In any case, WP should contain an article or substantial section about every major product line from a major company, though not a full article about every individual project. Some earlier merges of Avaya products reduced the content to a single line giving the name of the product in the main article. Those are destructive merge, and all such sections need to be expanded.  A single article about such a company and all its products is absurd undercoverage
