Multiple Frame Relay connection on PM 2ER

Hi John,
We have PM 2ER at my office which has T1 Frame Relay connection on th
W1 port to our Internet Service Provider.
We also like to use the same Frame Relay interface to connect to
remote office which has his own class C IP.
We use Cisco 2501 router at the remote office.

PM 2ER
set w1 address x.x.95.170 netmask 255.255.255.252
set w1 dici 17:x.x.95.169

This works fine for our connection to ISP.

Now the question is...

How can I setup another subnet for our Frame Relay connection to remote
office on the same W1 interface on our PM 2ER?
How can route the new class c IP ( x.x.36.0 ) in my PM 2ER ?
As my understanding that every virtual circuit connection has to be a
subnet and most of them are using netmask 255.255.255.252 which only has
2 ip to use.

The question is
Can W1 port has two or more subnet point to ?

I have tried
set w1 address x.x.95.170 netmask 255.255.255.252
set w1 dlci 17:x.x.95.169 16:x.x.95.173
but it does not work.
And...
set w1 address x.x.95.170 netmask 255.255.255.248
set w1 dlci 17:x.x.95.169 16:x.x.95.173
it does not work nether.

Please help me.
