Our only problem was to open a channel of communication with them.
For a long time the department was the only channel of communication between the people and the government.
The communications channels were just beginning to come clear again.
To get science into this communication channel can only be a good thing.
We must, however, keep the communication channels to the outside world open.
It is also used as a channel of communication between school and parents.
Team four would stay at the station and keep all the communication channels open.
After all, people also contact us using many other different communication channels.
We need better channels of communication between working scientists and the public.
That was what you wanted: your channel of communication - with all the help they could make available to him.
