Slovak Telekom, which is majority-owned by Germany’s Telekom, has successfully transferred its entire customer base to an Internet Protocol-based network. The company is the second Deutsche Telekom subsidiary to switch to “All-IP” in the past year, following Makedonski Telekom in Macedonia in February 2014. More than 35 percent of DT’s customer base in Europe is now using the IP network.
DT commented that Slovak Telekom’s migration to an All-IP network is “a vital step forward for the Deutsche Telekom Group on its way to establishing a pan-European, all-IP network”. All 678,000 Slovak Telekom business and residential customers have been switched to the IP network.
“By moving geographically and switching one entire exchange area at a time we realized the maximum benefits of migrating to the IP network, due to the corresponding effect on energy and maintenance cost savings,” says Branimir Maric, Chief Technology and Innovation Officer at Slovak Telekom.
“This concept was something we learned from our colleagues at the DT Group. We also copied the entire end-to-end cross functional migration processes blueprint. This is proof of the advantage of belonging to an international Group like Deutsche Telekom.”
A DT spokesman added, “Each time a national company goes through the IP migration, the lessons learned are added to a central blueprint that already contains input from experts from across the entire Group. This way, Deutsche Telekom can leverage its power as a truly European company.”
During the migration to All-IP more than 800 tons of obsolete technology equipment were removed from Slovak Telekom sites, 51 PSTN local hosts were shut down, complete SDH and ATM networks switched off and in total more than 6,500 network elements were removed from the Slovak Telekom network. In the future, with All-IP, Slovak Telekom is expected to enable increased broadband service coverage, higher quality of services with more options and network management for customers.
Slovak Telekom is said to be already seeing notable savings on energy, support and maintenance and warehouse costs for spare parts they no longer need to store. The hardware that is now in use is also more stable than it was on the old standard.
