This solution is very reliable and works well under harsh environmental circumstances. For example, if the air conditioning turns off then the switch doesn't shut down immediately.

The key feature, that is most valuable to us, is the Split-Multi link Trunking (SMLT). This feature allows us to create a very redundant/fault tolerant network across multiple data centers in multiple locations using our own fiber runs. We have been very fortunate to have such redundancy in place saving us some major outages. This redundancy has also allowed network upgrades to have much less of an impact to the customers. Also, the different interfaces provided with various modules have allowed us to migrate from one technology to another in various areas of our network without a complete overhaul, but in stages.

Another feature it has, is that the platform has changed both in software and hardware over the years. They have done it with new technology, features, and capacity, by simply upgrading/adding newer modules to adapt to our ever changing and growing network needs.

When compared to Cisco, Avaya's pricing and performance is good.

I have found the access control list and the filtering are the most valuable features. Also, the quality of service is great.

It supports virtual hot swappable feature where in the switch can be easily takeover requests from other switch which is momentarily down. This is completely transparent to the end user and thus improves overall responsiveness. 3. It can be easily wall mounted or rack mounted as needed. 4.
