This feature eliminates call blocking due to unavailable time slots. This
feature allows a time slot reserved for a primary function to be reused for any
subsequent requirements during call processing. Therefore, all channels on
Digital Trunk Interface (DTI) or Primary Rate Interface (PRI) loops are
available for use.
Time slots reserved for a particular DTI or PRI channel are stored in an
unprotected data structure allowing easy access, such as a call register. Each
time a new path is required for the same DTI or PRI channel, the data
structure can be accessed to determine if there is a reserved time slot that can
be reused. If the new path is intra-group (single-group switch), the time slot
can be reused. If the new path requirement is inter-group (multi-group
switch), the reserved time slot can be reused if a matching junctor slot is
available.
