NI-1 BRI Review

This appendix contains instructions for completing the NI-1 BRI Planner Form. If

you have questions while completing the form prior to the sale, contact the AT&T

National Technical Marketing (NTM) engineers. Once the contract has been

signed and the forms are completed, make a photocopy of the forms for your

records and forward the forms to the technician who will do the installation. The

technician will then fax a copy to the National Service Assistance Center (NSAC)

if any questions or problems occur at the customer site.

The NI-1 BRI Planner form should be used in conjunction with System Form 3i, In-

coming Trunks: BRI Options (800 NI-BRI Module).

Planning Form Instructions

NOTE:

Prior to completing any of the steps below, you should first verify that the custom-

er’s local service provider offers National ISDN-1 BRI service with ISDN Ordering

Code (IOC) standardized capability package “S” and a separate Multi-Line Hunt

(MLH) service, depending on the customer's requirements. If the Central Office

uses an AT&T 5ESS or Siemens SSC EWSD switch, MLH is available through the

Series Completion feature. The Multi-Line Hunt Group (MLHG) feature on these

CO switches is not recommended for use with MERLIN LEGEND. The Northern

Telecom DMS-100 provides MLH service through the MLHG feature. A customer

may want to order several BRI lines, some assigned as IOC package “S” and the

others as MLH.

To properly order and administer NI-1 BRI service, it may be necessary to contact

the local service provider to determine what services are available and the type of

switching equipment used. See Appendix H, ‘‘

NI-1 BRI Provisioning’’ for detailed

information that the local service provider may require in order to supply the nec-

essary connections.
