CTCM group devices
The CTCM device driver requires two I/O subchannels for each interface, a read subchannel and a write subchannel.
Interface names assigned by the CTCM device driver
When a CTCM group device is set online, the CTCM device driver automatically assigns an interface name to it. The interface name depends on the protocol.
Network connections
