Periphonics IVR system

The Nortel Networks Periphonics IVR system is a powerful IVR system that can
provide IVR functionality for thousands of ports, with up to 480 IVR ports
supported in a single cabinet. The Periphonics IVR system supports the following
IVR features:

• Large vocabulary speech recognition through its OSCAR speech server
• multiple speech recognition vendors, including Nuance
• self-service solutions which can include multiple layers.
• A GUI-based application builder (PeriProducer) for creating a range of basic

The system has two server elements: the voice processing series/information
server (VPS/is) which provides voice services, and the integrated package for
Meridian link (IPML) server.

Overview of the VPS/is

The VPS/is is a server that integrates a variety of call processing functions with
data communication and transaction processing. The server connects to the
Succession switch via a TI/E1 connection to a line side T1/E1 (LST1/EI) card on
the switch. The card provides the voice interface between the IVR system and the
Succession switch. The LST1/EI card emulates an analog line card to the
Succession software, and supports one T1/E1 line with 24/30 channels. You can
configure each channel separately.
