Link Layer Cmd/Rsp Role:
This field determines whether this LINCS platform is to provide the link layer clocking.
When set to DCE, LINCS will provide the transmit and receive clocks allowing direct
attachment to another X.25 platform without use of modems. When set to DTE, a modem is
required to provide clocks.
Link Layer Window Size
Select the link level window size that is consistent with the network subscription value. Values
are 1 - 7, the default is 2.
Response Timer
This number specifies the time in increments of .1 seconds that the X.25 software will wait to
receive a response, after transmitting a frame. The range is 1 to 9999.
Retry Count
This number specifies the number of times the X.25 software will retransmit a frame, after not
receiving an acknowledgment. LINCS will wait the amount of time specified in the Response
Timer field before retrying the transmit. The value range is 1 to 99, and the default is 10.
Receive Timer
The Receive Timer indicates the amount of time a link level acknowledgment will be delayed
to allow the packet layer (and above) to process the received frame and generate an information
frame as a response. This can improve link utilization. This decimal field accepts values from 0
to 2. The default is 1 tenth of a second. A value of 0 indicates that the option is disabled.
Logical Channel Numbering
The following fields describe the logical channel numbering for your network subscription.
The fields indicate the valid ranges for all incoming and outgoing calls.
• Lowest PVC - Specify lowest channel number of permanent virtual circuits
• Highest PVC - Specify highest channel number of permanent virtual circuits
• Lowest Incoming SVC - Specify lowest channel number of incoming calls
• Highest Incoming SVC - Specify highest channel number of incoming calls
• Lowest Two Way SVC - Specify lowest channel number of two-way calls
• Highest Two Way SVC - Specify highest channel number of two-way calls
• Lowest Outgoing SVC - Specify lowest channel number of outgoing calls
• Highest Outgoing SVC - Specify highest channel number of outgoing calls
All ranges must be in ascending order with no overlapping values. Only specify ranges for
the circuit types you are using. The total number of channels which are configured cannot
exceed 255. These fields accept values from 0 to 4095.
