First change the load-threshold 20 -> dialer load-threshold 1.
normal ICMP packet rarely exceed 20/255x64 kbps.
Or you should try with extended ping
R2#p
Protocol [ip]:
Target IP address: 150.50.9.5
Repeat count [5]: 100
Datagram size [100]: 1000
Timeout in seconds [2]:
Extended commands [n]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 100, 1000-byte ICMP Echos to 150.50.9.5, timeout is 2 seconds:
..!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Success rate is 97 percent (97/100), round-trip min/avg/max =
140/170/264 ms
R2#
IN prevous sample I have ping with 100 packet which each one is
1000Bytes
If it still not work, reload your simulator. I have some problem with
ISDN sim b4.

Alec, have you checked your ISDN sim yet to see if it is allowing more
than
1 call
on your spids?
If it isn't it doesn't matter what you configure on your routers, the
second
channel
will NEVER come up.

Alec,
Change the load-interval to 30 seconds with the load-interval 30 command
under the BRI interface. This controls how fast the load is calculated
on
the interface. This load setting is what PPP Multilink uses to determine
when to bring up the second B channel. The default setting is 5 minutes
I
believe. So with the default setting you would have to reach or exceed
the
load-threshold based on the average traffic over a 5 minute period. This
command reduces that to an average over 30 seconds.
HTH,
