Provides Customer Premises Equipment (CPE) compatibility considerations for the Voiceband Data Transmission Interface described in TR-NWT-000030, Issue 2, 10/92 and will replace SR-NWT-002024, Issue 1, 4/92. The document describes the compatibility considerations for CPE to operate with the voiceband data transmission interface used to transmit asynchronous data to CPE from its serving SPCS. The document also provides guidelines for error treatment, signal generation, and signal detection. It recommends a few design considerations for the CPE. A test plan for detection of the CPE Alerting Signal defined in the document is given in the appendices.
