ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 1
7-131
Only the new ISDN-PRI service application fields or those fields that require special or additional
considerations are mentioned here.
Group Type
Dial Access
Night
Service
Service Type
Usage Alloc
Far End
Test No
For ISDN-PRI service applications this field should be translated isdn-pri.
NOTE: The
SYSTEM-PARAMETERS CUSTOMER-OPTION screen must have ISDN-PRI
service enabled before this trunk group type can be translated.
Normally, this field is defined as y. However, for some public network connections
(such as service type CBC, MEGACOM, etc.), this field is defined as n.
If administered, then the extension number translated will receive all incoming calls
(for the particular trunk group) when the switch is placed in night service mode.
NOTE: Page 2 of the
TRUNK GROUP screen permits an override entry for each
particular type of ISDN network service. Also, trunk member night service is
allowed.
Assigns the service application for the ISDN-PRI trunk group. Since CBC permits
reduced costs (depending on tariff and application), an improved grade-of-service,
and customer premis control of networking, the option cbc should be considered for
public network applications. Other options include any of the predefined or
additional Services/Features listed in the Name field of the
NETWORK-FACILITES
screen. Also, the options access, tie, and tandem are permitted.
Field encodes and their descriptions are:
y Enable usage allocation for those services provided by the trunk group. Used to
maximize customer control of the allocation of CBC trunk group members to
services (such as preventing a service from monopolizing the member of a
group) .
NOTE: This option permits up to three usage allocation plans to be defined
for the identified trunk group. The term usage allocation is the ability to set
both a minimum and maximum number of trunk members that an ISDN
Service/Feature may use at a given time. Each usage allocation plan can set
limits for up to 10 services/features.
n
Disable usage allocation for the trunk group (default). This option places
restrictions on either the Services/Features that can be carried on the trunk group
or the number of calls that any one Service/Feature can have at any given time.
This is the number associated with the far-end’s test equipment and is reserved
exclusively for maintenance testing. The test number should be assigned for both
private and public networks. There is one test number per trunk group. As a part
of the installation and ISDN-PRI service provisioning process, the test number must
be coordinated with the terminating switch.
NOTE: This field is equivalent to translating procedure 108, word 1, for
Generic 2.
