  20          This module may be used for special applications that require
  21          cross connecting of bchannels, conferencing, dtmf decoding,
  22          echo cancellation, tone generation, and Blowfish encryption and
  23          decryption. It may use hardware features if available.

  36          It features:
  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
  41
  42          NOTE: This protocol is called 'Layer 1 over IP' and is not
  43          compatible with ISDNoIP (Agfeo) or TDMoIP. Protocol description is
  44          provided in the source code.
