How are terminal servers Numbered

[brooklynheight]

We have a 2621 acting as a terminal server-

on the back of it are 4 ASYNC slots

0-7

8-15

16-23

24-31

There are only LED lights on 0 ,1, 5,6, 7

8,9,13,12

But our configs shows this-

menu net text 1 L33 xxxrouter1

menu net command 1 telnet myport 2033

menu net text 2 L34 xxxxrouter2

menu net command 2 telnet myport 2034

menu net text 3 L35 xxxrouter3

menu net command 3 telnet myport 2035

menu clear text 1 Clear Line L33

xxxrouter1

menu clear command 1 clear line 33

menu clear text 2 Clear Line L34

xxxxrouter2

How are line numbers ..i.e 2035 associated with the acutal physical connection?

I see no physical connection 33,34 etc
