Case Study: Guaranteed Business Internet for an Office Complex in Prague 4 — Pankrác

Prague — Pankrác is one of the most significant office locations in the Czech Republic — a dense concentration of high-rise administrative buildings, headquarters of multinational corporations, law firms, financial institutions, and consulting firms make Pankrác a natural business center of Prague 4. For companies located in this area, the quality of internet connection is a direct part of operational infrastructure — and yet it happens that even in modern office buildings in Pankrác, customers encounter aggregated shared connections without contractual availability guarantees. New Telekom s.r.o. implemented for a medium-sized law and consulting firm in an office complex in Pankrác a guaranteed symmetrical business internet connection of 1 Gbit/s on FTTO fiber — with 99.9% SLA, redundant last mile, direct peering at NIX.CZ, and latency below 1.3 ms to Czech destinations.

What is the specific situation of business internet in Pankrác?

Prague — Pankrác combines seemingly contradictory characteristics: it is one of the most modern office locations in Prague, but at the same time a place where the quality of internet connections varies significantly across buildings. Modern high-rise buildings in Pankrác are well-equipped from a physical network infrastructure perspective — they have technical shafts, distribution rooms on each floor, and feeds for multiple operators. The problem arises when the building manager or developer has signed an exclusive or preferential contract with a single provider whose infrastructure does not meet tenants' requirements for guaranteed B2B parameters. The tenant then faces a choice: accept the existing conditions, or arrange their own dedicated connection from an operator who can actually deliver the guarantee. The customer — a consulting and law firm with 55 employees in offices in Prague 4 — Pankrác — was exactly in this situation. The existing connection from the building manager was shared with other tenants, without contractual availability guarantees, and with an asymmetric speed of 200/50 Mbit/s. For a firm transferring legal documentation, operating a cloud DMS (iManage), a VoIP system, and remote access for lawyers working from client premises, the low guaranteed upload and absence of SLA were a significant operational limitation.

What exactly did the customer need?

The requirements stemmed directly from the nature of legal and consulting operations:

• Symmetrical upload of at least 500 Mbit/s — uploading large files (due diligence documentation, notarial files, contract packages) was unacceptably time-consuming with the existing 50 Mbit/s
• SLA guaranteed availability of 99.9% with contractually defined response time — a law firm bills clients by the hour, and a connectivity outage during a transaction is direct financial loss
• Static IPv4 addresses for their own VPN server and SIP registration
• Low latency to NIX.CZ — the cloud DMS and video conferencing system (Microsoft Teams) are primarily connected to Czech infrastructure
• Implementation without outage of existing connectivity — the firm cannot accept even a one-hour outage during migration

How did New Telekom design and implement the connection in Pankrác?

Survey of available routes in the building in Pankrác

The New Telekom team performed a physical survey of the building in Pankrác — mapped existing cable routes in technical shafts, identified distribution rooms on each floor, and verified the entry point for bringing in a new fiber route from the public road. The survey confirmed available capacity in the existing utility conduits on the access route to the building and a passable technical shaft for vertical distribution up to the customer's floor. The survey confirmed available capacity in the existing utility conduits on the route between the backbone cable and the building, and a passable technical shaft for vertical distribution within the building up to the customer's floor. Physical implementation required no construction modifications or new permits.

Architecture: FTTO 1 Gbit/s with redundant last mile

New Telekom designed a primary FTTO connection with 1 Gbit/s symmetrical capacity and a backup LTE-A Pro connection as automatic backup — a standard architecture for office environments in Prague 4, where mobile coverage is reliable and excavation on the primary fiber route is a real risk in an area with intensive construction activity. Primary route: Dedicated OS2 Single-Mode fiber pair from the nearest distribution node to the building in Pankrác and via vertical shaft to the customer's floor — total route length on the premises and in the building 310 meters, terminated with LC/APC connectors on a patch panel in the customer's data rack. Measured route attenuation: 1.1 dB, certification according to ČSN EN 50346. Backup route: LTE-A Pro connection via New Telekom eSIM on a Juniper NFX250 router — automatic activation upon failure or degradation of the primary fiber, failover within 9 seconds.

Migration without outage

The customer explicitly required migration to the new connection without interruption of existing connectivity. New Telekom implemented the transition using a parallel operation method: the new FTTO connection was activated and tested simultaneously with the existing building manager's connection. The traffic switchover to the new connection took place on an agreed weekend date — the customer configured DNS records, the VPN server, and SIP registration to the new static IP addresses, and by Monday morning all traffic was operational on the new connection. The existing building manager connection was retained as a backup for 30 days after migration.

What was physically installed in Pankrác?

Fiber route and termination

• 310 meters of OS2 Single-Mode 4-fiber optical cable from the nearest distribution node to the customer's data rack in Pankrác, routed through existing utility conduits and the building's vertical shaft
• Termination with LC/APC connectors with attenuation below 0.15 dB on a 12-port optical patch panel in the customer's data rack
• Certification measurement of the entire route with EXFO FTB-720 reflectometer — attenuation 1.1 dB, protocol handed over to customer

Active equipment

• Juniper NFX250 — SD-WAN CPE router; primary fiber link and backup LTE-A Pro eSIM orchestrated by SD-WAN logic; BGP session to New Telekom network, IPv4/IPv6 dual-stack, 4× static IPv4 addresses for VPN server and SIP registration, QoS DiffServ with VoIP traffic prioritization (EF DSCP)
• Cisco Catalyst 9200-24P — access switch with 24× GbE PoE+ ports for powering IP phones (Cisco IP Phone 8800 series) and Wi-Fi access points without external power; 2× 10GbE SFP+ uplinks to router
• Fortinet FortiGate 100F — NGFW firewall with IPS, SSL/TLS inspection, and application control; separate security zones for office traffic, VoIP, and VPN access for lawyers from remote locations
• APC Smart-UPS 1500VA — backup power for active equipment for 45 minutes

Structured cabling in offices in Pankrác

In the customer's office spaces, New Telekom performed a partial renewal of structured cabling in part of the premises — the existing Cat 5e cabling in meeting rooms was insufficient for PoE+ powering of new IP phones and 1GbE speed for video conferencing systems:

• 280 meters of new Cat 6A S/FTP cable in four meeting rooms and the reception area
• 1× Cat 6A patch panel 24-port
• 18 data outlets with dual RJ45 Cat 6A ports
• Certification with Fluke Networks DSX2-8000 instrument according to ČSN EN 50173-2, class EA

What parameters did the customer in Pankrác achieve?

The most visible immediate change for the customer: upload of legal documentation. A due diligence document package of 8 GB, which previously took 25–30 minutes to upload over the shared connection, now uploads in less than 70 seconds after switching to guaranteed 1 Gbit/s. For a team of lawyers working with client billable hours, this is a daily measurable productivity change. Latency to Microsoft 365 below 3 ms — achieved thanks to New Telekom's direct peering at NIX.CZ in Prague — eliminated noticeable delays when working with SharePoint libraries of large documents and during shared file editing in Microsoft Teams.

Why is guaranteed internet in Pankrác more difficult to obtain than it seems?

Pankrác is a paradoxical location: it looks like an ideal place for enterprise connectivity, but the reality is more complex. Large office buildings typically have one or two preferred operators — and if neither offers truly guaranteed symmetrical parameters, the tenant must either accept a compromise or arrange their own connection. A dedicated FTTO connection from New Telekom directly into office spaces in Pankrác bypasses the building manager's infrastructure entirely — the customer has a dedicated fiber pair from the New Telekom Prague 4 backbone node all the way to their own data rack. The building manager and other tenants have no influence over the connection. This approach is available for most office buildings in Pankrác — implementation typically does not require extensive construction work and takes 3–5 weeks. Availability for a specific address can be verified as part of a free location survey.

What is the availability of guaranteed internet in other parts of Prague 4?

New Telekom ensures availability of guaranteed business internet across all of Prague 4 — from Pankrác through Michle, Krč, and Chodov to industrial zones along the D1 highway. Customers in these locations have access to the same level of connectivity — with direct peering at NIX.CZ, 99.9% SLA, and 24/7 New Telekom NOC technical support.

Frequently asked questions about guaranteed business internet for companies in Pankrác

Can I, as a tenant in an office building in Pankrác, get my own FTTO connection from New Telekom?

Yes — and that is exactly what New Telekom implements in such cases. A dedicated FTTO connection from New Telekom leads directly to your office space and bypasses the building manager's shared infrastructure. For passing the cable through common areas of the building (technical shaft, basement), the consent of the building manager or HOA is typically required — New Telekom handles this coordination as part of the project.

How does guaranteed internet differ from shared connection in an office building?

A shared connection from the building manager is aggregated capacity divided among all tenants — during lunch time or after work hours, when other companies are intensively downloading, actual speed drops. Guaranteed business internet from New Telekom is dedicated 1:1 capacity — the allocated speed is available at full capacity at any time, independent of other tenants. At the same time, availability is contractually guaranteed (99.9% SLA) with defined outage response time and repair time.

Can guaranteed internet in Pankrác be supplemented with a CloudConnect private link to Azure?

Yes — and it is a natural extension for companies in Prague that access Microsoft Azure or AWS via business internet. On the same physical FTTO connection, you can simultaneously operate guaranteed B2B internet and a CloudConnect private circuit to Azure ExpressRoute as logically separate layers. Access to Azure then does not go over the public internet, but via a dedicated private link — with guaranteed latency below 8 ms to the West Europe region and significantly lower egress costs.

How long does it take to deploy guaranteed business internet in Pankrác?

For locations in Prague 4 — Pankrác within reach of the New Telekom backbone network, the standard time from contract signing to activation is 3–5 weeks. The project described in this case study — including route survey, laying 310 meters of fiber, and installation of active equipment — was completed in 4 weeks. Migration from the existing connection took place without outage on an agreed weekend date.

Does New Telekom offer guaranteed internet in other office locations in Prague?

Yes. New Telekom implements guaranteed business internet throughout Prague — Prague 1 (city center, Old Town), Prague 2 (Vinohrady, Nusle), Prague 4 (Pankrác, Michle, Chodov, Krč), Prague 5 (Smíchov, Stodůlky), Prague 6 (Dejvice, Bubeneč), Prague 7 (Holešovice), Prague 8 (Karlín, Libeň), and other locations.

Conclusion

Guaranteed business internet in Pankrác — one of the most prestigious office locations in Prague 4 — is achievable even in buildings with an existing preferred operator: a dedicated FTTO connection from New Telekom directly into office spaces bypasses the shared building infrastructure and brings dedicated 1 Gbit/s symmetrical capacity, 99.9% SLA, latency to NIX.CZ below 1.3 ms, and automatic backup via LTE-A Pro — all under a single contract. For the law and consulting firm in this case study, this meant in practice an end to unpredictable speed on the shared connection, elimination of delays when uploading documentation, and Microsoft 365 and Teams availability at a level that matches their billable hourly rates.
