Agents cannot effectively represent Verizon Wireless rates and coverage on
a national basis without the automated delivery of rate plan information
from Verizon Wireless.
Rate Plan, Market & Equipment related data is extracted from the BackOffice
system by a scheduled process, which kicks off the application. The data is
sent over to the agent via XML over a secure socket connection. Client
authentication is done by means of digital certificates. The
acknowledgement is received in form of an XML string, which is then parsed
and appropriate status codes are recorded in the database.
