are the ranges of logical channel numbers (LCNs) that subscribers can use for calls
through this port. The valid values for each parameter are determined as follows:
Channel
Lowest Incoming
Highest Incoming
Lowest 2-Way
Highest 2-Way
Lowest Outgoing
Highest Outgoing
Changing any parameter to a value that violates this order automatically changes any
other values now in violation, specifying the first value(s) within the valid range. If
any pair is not used, its constraints apply to the next higher or lower pair (whichever
is appropriate) in the above list.
is an optional X.25 facility that permits negotiation of the flow control parameters
(packet and window sizes for either direction of data transmission) on a per call basis.
If this parameter is set to

direction of data transmission on a per call basis. If this parameter is set to

default value will be used.)
