H12
NXDS0
Contiguous
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:
Remote Access
The Remote Access screen is used to implement the Remote Access feature.
Remote Access permits a caller located outside the system to access the system
through the public or private network and then use the features and services of the
system.
Remote Access users can dial into the system using central office (CO), Foreign
Exchange (FX), Wide Area Telecommunications trunks (WATS), and Integrated
Services Digital Network Primary Rate Interface (ISDN-PRI) trunks. In addition,
a dedicated Remote Access Direct Inward Dialing number can be provided.
Valid entries Usage
y/n
Enter y to specify the ISDN information transfer rate for 1920
Kbps data, which includes 30 B-channels. When a PE is
administered to support H12, the hunt algorithm to satisfy a
call requiring 1920 Kbps of bandwidth uses a fixed allocation
scheme.
Valid entries Usage
y/n
Enter y to specify the NXDS0 multi-rate service.
Valid entries Usage
y
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).
H0 and NXDS0 “floating” scheme cannot both be
y.
n
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.
