2. Introduction to Dialogic ISDN Products

• Operator Services applications are able to automate large numbers of
telephone calls that require some kind of caller assistance. Such applications
include, but are not limited to, partially automated directory assistance,
calling card voice prompting, and collect calls.
• Telemarketing applications depend on a specific event/transaction. The
primary difference between telemarketing applications in a terminate
configuration and telemarketing applications in a drop-and-insert
configuration is that the latter allow for the use of an existing PBX and
telephone equipment.
• Protocol Conversion is a drop-and-insert configuration, without resource
boards, used to convert calls from one network protocol to another network
protocol.
2.3. Dialogic ISDN Protocol Support
A protocol is a set of rules or standards that defines the format and timing of data
transmission between two devices. Like any evolving technology, a single
standard ISDN implementation has yet to be agreed upon worldwide. Standards
have been established in a number of countries or regions. The following table
lists the protocols that Dialogic currently supports.
