Setting Rate Adaption
Rate adaption determines the number of data bits transmitted and their bit
positions within the timeslot to achieve the data rate. The term rate adaption
means that by setting this parameter, you are adapting to the rate of your
subscriber; the software does not change the rate dynamically.
The logical line rate adaption is 64 Kb/s by default. You can select one of the
options listed in Table 7-16
.
The 64K, 56K MSB, and 56K LSB options specify full DS0 rates.
The 9.6K and 19.2K options specify DS0A subrates for an SDLC connection, and
are available only for an installed QMCT1 with DS0A link module. If you choose
one of these options, you can assign only one logical line to a timeslot. See
“Configuring a DS0A Connection” earlier in this chapter.
Table 7-16. Rate Adaption Options
BCC Option Site Manager Option Description
adaption-64k 64K Sets the data rate to 64 Kb/s, using all 8
bits in the timeslot.
adaption-56kmsb 56K MSB Sets the data rate to 56 Kb/s, using 7 of the
8 bits in the timeslot, excluding the most
significant bit (MSB). The MSB carries
framing overhead.
adaption-56klsb 56K LSB Sets the data rate to 56 Kb/s, using 7 of the
8 bits in the timeslot, excluding the least
significant bit (LSB). The LSB carries
framing overhead.
adaption-9dot6k 9.6K Sets the data rate to 9.6 Kb/s, using DS0A
frame format.
adaption-19dot2k 19.2K Sets the data rate to 19.2 Kb/s, using
DS0A frame format.
