+ We recommend that you change the HF default value of 192 to 63 when operat-

ing VHF 1200 baud packet.
This command, used with SLOTTIME, implements an algorithm for channel ac-

cess to send packets. The algorithm used to determine whether or not to transmit

using the PERSIST/SLOTTIME method has been shown to be considerably more

efficient than the DWAIT method used by most standard AX.25 packet stations.

The result of using the persistence algorithm is increased throughput under most

channel conditions.
The value of “n” is used to determine if a packet will be sent after SLOTTIME

expires. For example, let’s assume a PERSIST setting of 63 and a SLOTTIME

setting of 10. This slottime setting corresponds to 100 milliseconds. When the

TNC detects that the channel is clear and available (no carrier is detected), it

starts a timer (SLOTTIME). When the timer expires (100 ms in our case) the

TNC generates a random number between 0 and 255. If the generated number is

equal to or less than the PERSIST value, the TNC keys up the transmitter and

sends the data packet. With our setting of 63 the odds of this occurring after the

first slottime are 1 in 4. (Actually the probability is PERSIST plus 1 divided by

256.) If the TNC generated random number is greater than PERSIST, the TNC

restarts the timer and waits for the timer to expire again before generating a new

random number. This is repeated until the TNC gains channel access and sends

its packet of information.
Making SLOTTIME smaller will cause the TNC to generate the random number

more frequently, whereas raising the PERSIST value will give a better chance

(improve the odds) of transmitting the data. Through careful choice of these val-

ues, it is possible to improve data throughput while at the same time permitting

shared channel usage by other packet stations. The persistence algorithm has

been added on top of the DWAIT algorithm.

Note:

When switching from 300 baud packet operation on HF to 1200 baud packet

operation on VHF/UHF, remember to change the following (HF defaulted) parame-

ters: Mark, Space, SWP, Slottime, Persist, Maxframe, Paclen, Hbaud. See the

packet section in the modes of operation chapter for further detail (page 144).
