transmission, the acknowledgment will be sent with it, and the delay timer will be
reset.
T3 Link Alive Period
is the length of time after which the node will poll its counterpart if there is no data
transfer.
Logical DCE
defines the port as (if
Y
) logical DCE or (if
N
) DTE. The other end of the connection
must be the opposite of this port. Logical DCE/DTE is independent of physical. A
node connecting a subscriber device into a network should normally be configured as
logical DCE.
Lowest/Highest Incoming/Two-Way/Outgoing Channel
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
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

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.
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 will be used. (If either is not
included, the default for that parameter will be used.)
Throughput Class Negotiation
is an optional X.25 facility that permits negotiation of the throughput classes for either
direction of data transmission on a per call basis. If
N
is selected, the default (
Maximum
Throughput Class
) will be used. If
Y
is selected, any throughput class included in a call
packet will be used. (If a class for either direction is not included, its default value will
be used.)
Local Charging Prevention
prevents calls (if
Y
) from being 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.
Reverse Charge Acceptance
authorizes transmission of incoming calls that request the X.25 Reverse Charging
facility. If
N
is selected for this parameter and a call requests Reverse Charging, the
call will not be transmitted.
