Case Study
Vocalcom, a leading provider of solutions for international call centers, has
deployed RAD Data Communications’ Vmux-2100™ voice trunking gateway to
eliminate poor performance E1 lines between Paris and a Casablanca call center.
“Our previous equipment suffered performance degradation at every peak in
traffic, and that created constant user dissatisfaction,” explains Anthony Dinis,
Vocalcom’s Director of Strategy and Development. “Communications quality is of
utmost importance in our operations, especially because poor voice transmission
can make it difficult to understand the accent of a non-native French-speaking
teleoperator,” he continues. The compression capabilities integrated into the
Vmux-2100 meet Vocalcom’s strict requirements and standards by regenerating
natural speech qualities.
“RAD perfected the Vmux to such an extent that the device generates the precise
amount of background noise that is necessary to ensure the user’s auditory
comfort on the line,” Dinis adds. This noise, moreover, is artificially generated at
the trunk end point to save bandwidth. Given that a single E1 leased line between
France and Morocco costs ,000 per month, every single kilobyte that can be
saved is valuable. While call centers are now being relocated offshore at a rapid
pace, the cost of international telecom links can considerably erode expected
savings. “The voice compression capability of the Vmux was the second argument
in favor of choosing the RAD solution, since the savings in labor costs accrued by
the offshore relocation of the call center cannot be compromised by higher than
necessary transmission costs,” Dinis notes.

Simplicity Allows Complete Installation Within Two Hours
Working in tandem with Vocalcom, Connect Data, a RAD Data Communications
distributor partner in France, installed a Vmux-2100 voice trunking gateway at
each end of a single 2 Mbps international link, compressing each 64 kbps channel
down to 4.7 kbps. The compressed voice allows the remaining bandwidth to be
allocated to the transmission of data, including the user’s data records that appear
on the teleoperator’s screen when a call is made to the center. While the
maximum compression capability of the Vmux allows for up to 16 E1 lines to be
multiplexed onto a single link, a total of eight E1 lines are compressed in this
particular application. This saves Vocalcom a total of 16,800 per month in leased
line costs while still providing an option for potential expansion in the future.
“The Vmux-2100 units were fully installed within two hours, which illustrates the
simplicity that characterizes the product’s day-to-day operations as well,” notes
Ron Sapir, Senior Vmux Product Line Manager at RAD Data Communications.
“The fact that the product pays for itself in less than one month testifies to its
seamless operation and competitive pricing.”
