37	    - dynamic IP exchange, if one or both peers have dynamic IPs
38	    - BRI (S0) and PRI (S2M) interface
39	    - layer 1 control via network keepalive frames
40	    - direct tunneling of physical interface via IP

42	  NOTE: This protocol is called 'Layer 1 over IP' and is not
43	  compatible with ISDNoIP (Agfeo) or TDMoIP. Protocol description is
