From what I can tell you have set the digit "8" as you LCR activation code in MMC xxx. Once 8 is pressed, the following digits are compared to MMC xxx to determine how to route the calls. So if the number you are calling is 876-4782, you could place 8 in MMC xxx with a Length of 1 and a Route of 1. In MMC xxx you would assign your trunk group to route 1, so let's say it is 901. In MMC xxx as long as 901 has your PRI trunks and in MMC 210 LCR is enabled you should be good to go. So now this is what will happen: Press "8" you will see LCR: in the display. Dial the number, "876-4782" it checks MMC xxx and evaluated the 1st digit becasue the length is 1. It now routes the call to group 901, because that is what is assigned in MMC xxx.

I hope this helps.
