Supposedly speaks Abis.
Well, if it's a BTS, by definition it speaks Abis. However, Abis is not fully standardized, and every vendor has their own dialect. We reverse-engineered the dialects of Siemens, Nokia, Ericsson and ip.access to support them in OpenBSC, OsmoNITB and today OsmoBSC.
However, what is required for anyone looking at implementing this, is at the very least some protocol traces from a working installation of those (or at least any other) Huawei BTS towards a Huawei BSC.
Also, as the documentation states it uses IPsec, there is the question on how to configure the BTS with the correct configuration/credentials to connect to your own IPsec gateway.
