Lowest/Highest IncomingTwo-Way/Outgoing Channel
are the ranges of logical channel numbers that subscribers can use for calls through
this port. The valid values for each parameter that is used are determined as follows:
Channel Valid Values
Lowest Incoming 1
through
Highest Incoming
Highest Incoming
Greater than/equal to
Lowest Incoming
Lowest 2-Way
Greater than
Highest Incoming
Highest 2-Way
Greater than/equal to
Lowest 2-Way
Lowest Outgoing
Greater than
Highest 2-Way
Highest Outgoing Lowest Outgoing
through
4095
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.
Default Window Size
will be assigned to an incoming call setup packet if the packet does not request a
window size.
Default Packet Size
will be assigned to an incoming call setup packet if the packet does not request a
packet size.
Flow Control Negotiation
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
N
is selected, the default packet and window sizes will be used. If
Y
is selected, a
packet and/or window size included in a call packet, up to the
Maximum Packet Size
and/or
Maximum Window Size
configured in this Port record, will be used. (If either is
not included, the default for that parameter will be used.)
Thruput Class Negotiation
is an optional X.25 facility that permits negotiation of the throughput classes (line
speeds) for either direction of data transmission on a per call basis. If
N
is selected, the
Maximum Throughput Class
value will be used. If
Y
is selected, any throughput class
included in a call packet, up to the
Maximum Throughput Class
, will be used. (If a class
for either direction is not included, the
Maximum Throughput Class
value will be used.)
Local Charging Prevention
if
Y
is selected for this parameter, no calls can be charged to this port. Incoming calls
from the network with Reverse Charging specified will be rejected; outgoing calls will
have Reverse Charging inserted if it is not already in the call packet.
Default Calling Address
will be inserted into to an incoming Call Request packet if the packet does not contain
a calling address.
