I have done some testing on the MPLS interoperatibility between ALC-7750 and Cisco 7600 and they seem to work fine.
Are you after a specific implementation?
I have tested the below:
1. EoMPLS
For this, the Alcatel implements it as an EPIPE service using an SDP which in Cisco is simple a targetted LDP session to the ALC. Rest is simple
MPLS L3VPNs
For this, the Alcatel uses what is called VPRNs using same BGP VPNv4 exchange and RD/RT concepts as used by Cisco.
