- Yes. In the U.S. they use REN (Ringer Equivalence Number). In
- general, the REN's of units on a line should not exceed 5.0.
-
- Canada uses LN, or "Load Number". The concept is similar to REN,
- except that it is on a scale of 0-100.

- As long as you don't exceed REN=5.0 you **should** be O.K.; but check
- with the vendor for PBX applications; not all of them adhere to the
- 5.0 limit.

- REN=U.S. LN=Canada.

-
- By law in both the U.S. & Canada the REN and/or LN has to be listed on
- the unit in a conspicuous place, most likely on the label.
