Specifies whether to hunt contiguous NXDS0 channels. This field only appears if y is entered in
NXDS0. The hunt algorithm to satisfy an NXDS0 call is as follows:

Usage
Enter y to specify the "floating" scheme. NXDS0 calls
are placed on a contiguous group of B-channels large
enough to satisfy the requested bandwidth without
constraint on the starting channel (no fixed starting point
trunk).
Enter n to specify the "flexible" scheme. NXDS0 calls
are placed on any set of B-channels on the same facility
as long as the requested bandwidth is satisfied. There
are no constraints, such as contiguity of B-channels or
fixed starting points.
Usage
Enter y to specify the ISDN information transfer rate for
384 Kbps of data, which is comprised of six B-channels.
When a PRI Endpoint is administered to support H0, the
hunt algorithm to satisfy a call requiring 384 Kbps of
bandwidth uses a fixed allocation scheme.
Usage
Enter y to specify the ISDN information transfer rate for
1536 Kbps of data, which is comprised of 24 B-channels.
When a PRI Endpoint is administered to support H11, the
hunt algorithm to satisfy a call requiring 1536 Kbps of
bandwidth uses a fixed allocation scheme.
