NORSTAR UPGRADE QUESTION
Bruce, very few people run ISL anymore. I think it is straight X21. With the widely available t1 card and drop and insert dsu/csu's there are very few, if any, ISL installations anymore. Are you using voice compression with a dchannel to get the maximium amount of voice channels for the amount of bandwith that you have?
