Should be straight forward. First off, I would try and avoid using vlan1 as one of your vlans, It is the default vlan used when no vlans are configured and may cause some issues down the road. on the port that is connected to the cisco switch on the nortel, make sure both vlans are included in the access list and that the port is set to trunk under the port vlan tab if using Java Device Manager. on the Cisco, you would do something like this in config mode.
interface fastethernet0/20
switchport trunk encapsulation dot1q
switchport mode trunk
exit
exit

you can optionally add the command under the interface
switchport trunk allowed 2-3
or whatever the vlan list you want on that port otherwise all vlans configured on the switch will be allowed out of the port. Depending on the version of the IOS, i think you also need to issue the command vlan database from exec mode and create the vlans you want to use. Hope this helps or at least points you in the right direction.
