Option 11C
ISDN BRI Administration and Maintenance
Configuring the LAPD protocol group
A protocol group is added by using LD 27 and specifying its protocol group
number. You also change its LAPD parameters or accept the default values.
LAPD is a transmission protocol that specifies the transmission timers, the
maximum number of retransmissions, the size of the data frame, and the
number of negative acknowledgments before the system issues an alarm.
