LIN vs RRB

[TimAbney]

OK I can't find the definitions anywhere but this is what I remember:

LIN search starts at member 1 and fills using the next available trunk.

RRB selects the longest idle trunk.

Just loking for some confirmation, thanks.

RRB search for outgoing member and take the next lower one not in use.

lin - highest member it can find on 2 way trunks

LIN will use the same trunks over and over. For example say you have 15 trunks on a T-1 and you make a call hang up, there is a very high chance you will get the same trunk. Also using LIN is you have a bad trunk in the group you will not get past it. Using RRB chooses the next available trunk letting your PBX share the load across the T-1.

Relates to outgoing from user: LIN selects trunks from the highest member number, but within the same network group as they (the user) are in. It proceeds until no more trunks in the route are available within the users network group, and then begins at the highest member number in any other network group.

RRB does not use time, it only selects the next lower member available to make any call. In an idle trunk route, 24 calls will have used all 24 trunks, regardless of duration. Network Group rules still applies. Users will never select trunks in another network group is some are still available in their own network group.

For definition "Network Group" as in a multi-group Option61/81 or CS1000 large system. Small systems are always one group.

And yes with LIN you will attempt, then hop over bad trunks unless they are loop start.
