AT&T DS1/DMi/ISDN-PRI manual Dial Access, Service Type, Options access, tie, Usage Alloc

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 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.

Dial Access	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.
Night	If administered, then the extension number translated will receive all incoming calls
Service	(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.
Service Type	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.
Usage Alloc	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.

Far End This is the number associated with the far-end’s test equipment and is reserved

Test No 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.
