Which 24-Port Gigabit Switch for Q-in-Q trunk

Hello,

I have recently got a connection from a Telco to interconnect 2 of our sites. So far I have been using Microwave Links to do this but for higher capacity we have rented a circuit. I usually use a configuration like this on the interface where the payload for the Microwave Link is connected to:

interface GigabitEthernet0/14
 description Licensed Link 01-A
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 411,419
 switchport mode trunk

This will simply pass the allowed vlans between the 2 locations

Now with the new circuit I can only use this configuration on site A, on site B I have to use vlan10 within which I find my vlans 411 and 419. The C3560G series switches we use so far don't seem to support this type of vlan encapsulation. I was told its called Q-in-Q. Would the C3750G series do this for me ? Will i need the IP Services Image or is the IP Base Image fine for this ?

Kind Regards
Jan
