Configuring ATM Over MPLS Trunks
ATM over Multi-Protocol Label Switching (ATMoMPLS) trunks support a 
multiservice MPLS core solution by enabling connection of Lucent ATM switches to 
MPLS core networks via Juniper T-series (T640 & T320) routers running JUNOS 
Release 6.2 or above.

Note  – Use of the ATMoMPLS Trunking feature requires an additional license, which 
you must purchase from Lucent Technologies. The license is supplied as a 50-byte 
alphanumeric key that you enter at the Navis EMS-CBGX command line to unlock 
ATMoMPLS management features for use on the number of switches permitted by 
your license. For more information, refer to “ATMoMPLS Trunk Licensing” on 
page 8-2.
