When you purchase PRI from your service provider, you can request the number of B-channels
that are allocated for you to use. For example, you may want to use only 12 B-channels instead of
23 B-channels. If you do not have all of the PRI B channels, you should disable all the B-channels
that you do not need.
It is recommended that the number of lines that are deprovisioned on an DTM (configured as PRI)
be the same as the number of b-channels that are disabled. For example, If the DTM is on bus 7,
when b-channels 13-23 are disabled, you should deprovision lines 73 to 83.
