ABSTRACT: This GR presents the Telcordia view of generic requirements for a Visual Message Waiting Indicator (VMWI). VMWI is an SPCS feature that activates and deactivates a visual indicator on Customer Premises Equipment (CPE) [e.g., a flashing Light Emitting Diode (LED)] to notify the customer that NEW messages are waiting. The messages are administered by a third party, an Independent Service Provider (ISP).

GR-1401 replaces TR-NWT-001401, Issue 1, but contains NO TECHNICAL CHANGES from that original document. It has been issued strictly to conform with the new Telcordia Technologies document format and GR process, and carries a new issue number and date.
