Note:
All B-channels that comprise the wideband call must reside on the same
Note:
ISDN-PRI facility. Also, all trunk members in an ISDN trunk group with the
Wideband Support field set to y must be from a TN464C (or later) circuit pack.
H0
Enter y 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.
H11
Enter y 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 H11, the trunk/hunt algorithm
to satisfy a call requiring 1536-kbps bandwidth uses a fixed allocation scheme.
H12
Enter y 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 H12, the trunk/hunt algorithm
to satisfy a call requiring 1920-kbps bandwidth uses a fixed allocation scheme.
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).
