Xmit Conn
Each channel is assigned a connection number by the H.221 processing
code. This number is transmitted as part of the frame alignment word.
This field reflects the value assigned to the transmit connection for an
active port. The value for Port A is usually 1. The value for Port B is
usually 2.
Recv Conn
Each channel is assigned a connection number by the H.221 processing
code. This number is transmitted as part of the frame alignment word.
This field reflects the value assigned to the receive connection for an
active port.
CRCs Active
Indicates whether the 4-bit cyclic redundancy check (CRC) is being used
by an active port (on) or not (off).
This is an optional algorithm that helps provide end-to-end quality
monitoring. If one end of the connection is not using the CRC facility,
the other end’s CRC facility must be turned off as well. (AppsView
automatically turns the CRC facility on or off.)
