Yes, you can. Great question.

I have just updated the cnPulse Knowledge Base with a post that covers this topic.

> If you want to use cnPulse to provide GPS Synchronization timing to a 450b or a 450 MicroPoP device, you can use the Timing Port to do so. Cambium Networks sells a part for this, N000000L127A. If you’d like to create your own cable, the diagram is below. Note that this cable connects the TRRS (3.5 mm audio jack) to the RJ-45 (Ethernet) Timing Port of the cnPulse.
