Thank you Kim, for mention the clock requirement.
For the original poster, here is the relevant document from CCO
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/wan_
c/wcdatm.htm#xtocid150
(watch for the word wrap).
I use a SC-SC fibre to connect the routers back-to-back, RX to TX.
Here is the physical cable`s picture:

FYI, the following command is to check the interface`s clocking
r9#sh atm int atm2/0
Interface ATM2/0:
AAL enabled: AAL5 , Maximum VCs: 4096, Current VCCs: 1
Maximum Transmit Channels: 0
Max. Datagram Size: 4528
PLIM Type: SONET - 155000Kbps, TX clocking: INTERNAL
Cell-payload scrambling: ON
sts-stream scrambling: ON
27546 input, 13752 output, 0 IN fast, 0 OUT fast, 0 out drop
Avail bw = 155000
Config. is ACTIVE
