Over 10 years a heterogeneous network primarily
employing Cisco switches and routing technologies had
evolved to connect the headquarters with the branch
oces. Over recent years, this outdated network
had become progressively more unreliable leading
to availability issues while network support and
maintenance costs had escalated. A telephone system
comprising analogue and Integrated Services Digital
Network (ISDN) Basic Rate Interface (BRI) telephony
also linked the sites. The company had leased the ISDN
voice network from a telecommunications provider.
“Communications, collaboration and delivering
IT services to the 1,200 end-users in our oces,
treatment plants, engineering departments and
testing laboratories had become increasingly dicult
due to the age of our networking infrastructure,”
explains Csaba Hornyák, IT manager, Transdanubian
Regional Waterworks Corporation (DRV). “Both Local
Area Network (LAN) and Wide Area Network (WAN)
problems and general manageability issues frequently
led to internal customer service setbacks. Our network
simply didn’t oer enterprise performance, lacked
Quality of Service (QoS) and wasn’t suitable for
delivering services across our large eld of operation.”
To enhance internal and external communications
and collaboration, increase customer service
levels and reduce costs, DRV sought a unied
networking and telecommunications solution to
link headquarter operations, a secondary disaster
recovery site in Széplak and all branch oces. More
cost-eective IP telephony would replace the existing
telecommunications system.
“As our IT infrastructure already contained several
Microsoft solutions including Microsoft Oce,
Exchange, SQL Server and SharePoint, we decided to
implement the Microsoft Lync instant messaging, web
and conferencing solution,” continues Hornyák. “That
is when we heard about the HP/Microsoft Frontline
Partnership and brought HP Networking into the
solution qualication process.”
The most important networking criteria for DRV
was a full integration capability with Microsoft Lync,
high resilience and performance, sucient capacity
to support IP telephony and other applications,
and scalability to support growth. DRV conducted a
prequalication process with several networking and
IP telephony specialists including Avaya, Cisco and
HP. Delta Group, a local HP Gold Preferred Partner,
represented the multinational business during the
presales and subsequent phases of the project.
“The HP/Microsoft Unied Communications solution
integrates well with our existing infrastructure,
oers better performance than the Avaya or Cisco
solutions and will deliver a sound return on investment
(ROI). We estimate the payback time to be between
two and three years. It was the best solution,”
comments Hornyák.
End-to-end solution
Designed, tested and implemented by Delta Group,
the HP Networking solution deployed across DRV’s
head oce and secondary site comprises four
redundantly congured HP Networking 5800 core
switches and 44 HP Networking 3100El intelligent
edge switches, which deliver 528 access ports to each
site. The branch oces and other remote locations
contain an additional 83 HP Networking 3100El
intelligent edge switches. The new infrastructure has
a 10GB backbone and all switches deliver Power over
Ethernet (PoE) to support IP telephony.
The Microsoft components of this end-to-end Unied
Communications and Collaboration solution involve
providing voice capabilities to Microsoft Lync and
deploying Microsoft Exchange 2010. Microsoft Lync
Voice combines traditional IP PBX voice user features
and more exible Unied Communications alternatives
such as instant messaging. DRV users can therefore
employ their computers or desktop IP phones as their
main business communications device.
