CONTROL OF TELEMETRY INTERFACE GATEWAY DURING A VOICE CALL

摘要

Relates to apparatus and methods for permitting an agent of a utility or service bureau to access customer metering equipment before or during a conversation with the customer. For accessing before a call, while the customer is still on-hook, an alert signal is sent to activate the telemetering equipment prior to establishing a voice connection. For accessing during the call, an alert signal is sent while the customer is off-hook. Advantageously , measurement can be made in conjunction with the oral contact with the customer, thus making customer contacts more efficient and providing better service to customers.
