• Increased revenues, expanded customer base and improved customer service
• Simplified administration
• Future-proofed networks.
Reliability
Customers are searching for a voice/data solution that provides the ultimate in reliability. The
heartbeat of any business is its ability to send and receive information (through phone calls, data,
images) to and from customers and suppliers. Dial tone is not an option and companies need to be
able to rely on their network to transmit the required information as quickly and reliably as
possible. Our customers are not in the business of managing technology. They require highly
reliable solutions that allow them to focus on their core business.
The BCM Media Services Card (MSC) provides reliable call processing and media processing of
voice channels and contains media services processor expansion cards that provide digital signal
processing (DSP) resource control for applications. MSC call processing operates independently
of the BCM platform’s Microsoft NT Embedded
v. 4.0 operating system (OS). If the OS malfunctions, call processing remains unaffected.
Availability
With the expanding use of the Internet to connect businesses together with their customers and
other businesses, office hours are increasing to 24 hours a day, 7 days a week, 365 days a year for
more and more companies. Converged systems not only have to operate reliably – they have to be
available reliably to match these hours. Business applications and voice/data solutions allow
unattended systems to carry on a company’s business when all staff members at that location
have gone home for the day.
Built in with the design of the BCM are features that increase availability. The DSP resources of
the Media Services Card mentioned above, along with the system’s central processing unit
(CPU), provide redundant processing capability. A number of strategies can be used with the
BCM to increase system availability even further. The Redundancy Feature option provides dual,
hot swappable power supplies along with dual chassis cooling fans and data protection with
RAID hard disk drive mirroring. External uninterruptible power supplies connected to the BCM
can be used to handle power interruptions. And, the hardware platform’s unique Design for
Serviceability features minimize downtime for servicing of the BCM.
