All modular MX80 boxes should do SyncE. But IEEE 1588-2008 (PPT) needs better oscillator and -T denotes this. I think the non-modular models don't support even SyncE without -T model. It really looks like design fault that they needed better oscillator for the modular boxes, I'm pretty sure they planned to support PPT in all modular boxes. Possibly original oscillator was of poorer specs than they expected it to be? Since they're not exactly expensive components, makes no sense to have model for SyncE and model for SyncE+PPT. MPCx and MPCxE difference also should be same, better oscillator for PPT. (and supposedly 256M->512M FIB, i.e. 2M -> 4M routes or so). -- ++ytti _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
