ABSTRACT: GR-228 replaces TA-TSY-000228, Issue 1, but contains NO TECHNICAL CHANGES from that original document. It has been issued strictly to
conform with the new Telcordia document format and GR process, and carries a new issue number and date.
This document describes the Telcordia view of the generic preliminary human factors criteria for interoffice Network Terminal
Equipment (NTE), specifically Digital Cross-Connect Systems (DCS) and Automated Digital Terminal System (ADTS). (For technical criteria
refer to TA-365-23221-84-01, Digital Cross-Connect System Preliminary Requirements [no longer available] and
TA-365-23221-84-002, Automated Digital Terminal System Preliminary Requirements [no longer available]). These criteria have been
developed on behalf of the Local Exchange Carriers (LECs) to be used by NTE suppliers in the design of their NTE and by Telcordia
Technologies, Inc., which will perform NTE analyses based on these criteria.
The new microprocessor controlled NTE is likely to have an impact on the telephone company operations as great as the impact the
stored program control switches (SPCS) had on switching operations. This document is intended as an aid for designing the new NTE to
minimize the problems in integrating it with the present mode of operations, and to optimize the efficiency, safety and satisfaction
derived from these operations.
When using GR-228, you may need to refer to GR-63 (replaced PUB 51001) and TR-TSY-000825 (replaced PUB 54100). You may also
want to refer to TR-NWT-000170 (replaced TA-365-23221-84-01) and/or TR-TSY-000174 (replaced TA-365-23221-84-002).
