H0
Enter

to specify the ISDN information transfer rate for 384-kbps of data, which
is comprised of six B-channels. When a trunk group is administered to support
H0, the trunk/hunt algorithm to satisfy a call requiring 384-kbps of bandwidth
uses a fixed allocation scheme.

to specify the ISDN information transfer rate for 1536-kbps of data, which
is comprised of 24 B-channels. When a trunk group is administered to support

to specify the ISDN information transfer rate for 1920-kbps of data, which
is comprised of 30 B-channels. When a trunk group is administered to support

NxDS0
Enter
y
to specify the “N by DS-zero” multi-rate service.
Contiguous
Specifies whether or not to hunt contiguous NXDS0 channels. This field only
appears if the NxDS0 field is

y
.
The trunk/hunt algorithm to satisfy an NXDS0 call is as follows:
— 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).

fixed starting point trunk).
NOTE:
H0 and NXDS0 “floating” scheme cannot both be
y
.
— 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.
