This OID sets the LAPD T200 timer to a value between 100 and 350 milliseconds (in 50ms steps), controlling how long to wait before retransmitting a link message. Network engineers tune this based on link quality—higher values tolerate slower networks but delay error detection, while lower values catch failures faster. For example, a setting of 200 milliseconds means if no response arrives within 200ms, the device automatically resends the message.
