Hi Earl,
Good Day! :-)
Its not possible to omit the last 0 because once you configured 'channel-group x timeslot command' a serial interface is created and x(channel-group number) will be at the end of the serial interface just like what you have on your router.
About the available bandwidth please see below my explanation.
######
Here is a link that explains weighted fair queueing (WFQ) on an interface. That is what you are
using on that interface for your queueing. The link will explain how the available bandwidth is
calculated. Basically you cannot use more than 75 percent of the link for any type queueing and that
is the percent you see in the show int. 2048 multiplied by 75% = 1536. Please see the link the
below.

You can configure class policies for as many classes as are defined on the router, up to the maximum
of 64. However, the total amount of bandwidth allocated for all classes included in a policy map
must not exceed 75 percent of the available bandwidth on the interface. The other 25 percent is used
for control and routing traffic.
(To override the 75 percent limitation, use the max-reserved bandwidth command.) If not all of the
bandwidth is allocated, the remaining bandwidth is proportionally allocated among the classes, based
on their configured bandwidth. Please see the link below.

I hope I was able to provide the information that you need.
