LightHouse(R) Distribution Monitoring Solution Expands
        Portfolio With the Addition of Integrated Cellular
                           Connectivity

RESTON, Va., June 12, 2012 (GLOBE NEWSWIRE) -- Tollgrade
Communications, Inc., a leading provider of real-time monitoring
solutions for utility companies, today announced the formation of an
agreement with Sprint. This agreement will enable Tollgrade's
LightHouse distribution sensor solution to communicate wirelessly via
the Sprint network, eliminating the need for utilities to create or
maintain a private communications network, and simplifying integration
while adding flexibility at a lower cost.

"With the rising demand for energy and natural resources,
machine-to-machine solutions give utilities and their customers a
powerful emerging tool for automating services, managing demand and
promoting sustainability," said Wayne Ward, vice president-Emerging
Solutions Group, Sprint. "Our collaboration with Tollgrade underscores
our commitment to helping the utility industry improve efficiency.
Monitoring the smart grid is an example of how connected devices are
changing every aspect of our lives."

Tollgrade's LightHouse monitoring solution consists of inductively
powered medium voltage line sensors, communicating wirelessly with
Tollgrade's proprietary analytics software. The system instantaneously
detects and communicates key circuit events to a central location,
enabling utilities to improve grid performance. The detection of key
parameters, including load profile monitoring, allow utilities to make
better informed decisions and achieve superior grid visibility for
fault detection and fault location, vegetation management, load
balancing, power quality, asset management, and substation automation.

Deployment of Tollgrade's LightHouse cellular line sensor presents a
range of benefits for utilities, including:


  --  Full coverage throughout the United States and Canada to facilitate the
      immediate deployment of sensors through a utility's footprint
  --  Simplified deployment and management of a single communications
      infrastructure, eliminating the need to perform separate integration of
      multiple devices, or to develop a private communications infrastructure
  --  Reduced solution cost with simplified installation and maintenance,
      allowing information to be sent directly to the utility's data center
  --  High bandwidth and low latency for real-time awareness of grid
      conditions and to trigger critical alarms




Tollgrade's distribution line sensors enable utilities to seamlessly
provide service to their customers by optimizing the overall
operational status of the distribution grid.

"We are very excited to provide our utility customers with a cellular
version of our medium voltage sensor," said Tollgrade's Director of
Smart Grid, Erik Christian. "At Tollgrade, we are continually looking
for ways to give utilities the tools they need to avoid critical asset
failure and improve capital and reliability planning. We are confident
that our integrated Sprint cellular option will offer utilities the
ubiquitous and reliable coverage they require for better visibility
into the distribution grid."
