Depends on the platform. If you're using this WIC in a 1600/1700, you
can do async. If you're using in a 2600/2600XM, 3600, etc, it doesn't
support async. See the Platform Support Matrix here:

It seems to really do what you want with a higher-end router (i.e. 3600
series) you'd need the NM-4A/S or NM-8A/S (the A/S means it can do Async
or Sync). See:
http://www.cisco.com/en/US/products/hw/modules/ps2797/products_tech_note
09186a00800a93f1.shtml
Having said that, why is it that a module that obviously supports a
feature, and you know Cisco can make the IOS support it, can't be used
in any router that handles WICs? We have a NM-4T and I went to install
it into a 2600 today, and after rebooting thrice and it not recognizing
it, I went and found that the 2600/2600XM doesn't support this module.
WTF?!?! (From the second URL above) You can see that the 2600 will use
the NM-4A/S and even the NM-8A/S. So the 2600 can support up to 8 -
2Mbps sync serial connections, but supoort the NM-4T? Gimmie a
break..... What's the point in a common form factor (NMs and WICs) if
anything that it plugs into can't support it's features? One may argue
that the 3600 has something that's needed to support the higher
bandwidth (or whatever) than a 2600 (I don't buy this as obvious the
2600 can handle 8 such T1/E1 connections with the NM-8A/S). Even so,
you CAN'T tell me that a 1600/1700 has something that a 2600/3600
couldn't handle (i.e. async mode? Come on!)
So I can use a 3600 to run 8 T1s, or handle 2 ISDN-PRIs with 48 MICA
modems (async, which we run for a dial-up box) but that same 3600 won't
run 115.2Kbps async on a module that obviously supports that mode?!?!?
Geez...... Seems fishy to me...

This example is for an A/S card but I believe it will work on
synchronous cards if I recall correctly. The "physical-layer async"
command is the key.
