Telecommunications Operator Network Equipment

The network infrastructure of a telecommunications operator (ISP, Internet service provider, MVNO) requires high-capacity transit routers (Juniper MX, Cisco ASR), DSLAM/OLT fiber aggregation, a mobile core (5G SA), and global peering. 2026 operator equipment guide.

Operator architecture

Access

• DSLAM (ADSL/VDSL): declining
• OLT (Optical Line Terminal) for FTTH GPON/XGS-PON: Nokia 7360, Huawei MA5800
• Dark fiber leasing for large enterprises
• 5G RAN: gNodeB (Ericsson, Nokia, Samsung)

Metro/Backhaul

• Cisco NCS 500/5500: metro IP
• Juniper ACX 7000: backhaul
• Nokia 7250 IXR
• 100G-400G capacity

Core/Backbone

• Juniper MX10008/MX240/MX480/MX960/MX2020: PE/P routers
• Cisco ASR 9000 (9904/9906/9912/9922): high-capacity core
• Cisco NCS 5500/6000: next generation
• Nokia 7750 SR: European operators
• Capacity: 400G per port, 100-800 Tbps total

Operator protocols

• Full Internet BGP table (950K+ routes)
• MPLS L2VPN + L3VPN for customers
• Segment Routing (SR-MPLS): replaces LDP/RSVP-TE
• Segment Routing IPv6 (SRv6): emerging
• BGP-LU (Labeled Unicast) for scalability

Peering

• Public peering: IXs (France-IX Paris, LINX London, AMS-IX)
• Settlement-free peering: Tier-1 operators exchange traffic without payment
• Transit: paid service; Tier-2 pays Tier-1
• Ports: 100G, with migration to 400G underway

5G SA (Stand-Alone)

• 5G SA = dedicated 5G core (not 5G NSA on an LTE core)
• Core: AMF, SMF, UPF (User Plane Function)
• UPF deployed at the edge: MEC (Multi-Access Edge Computing)
• Network slicing: partitioning the network for use cases (IoT, video, URLLC)
• Vendors: Ericsson, Nokia, Huawei, Samsung (outside EU/US), Mavenir (Open RAN)

Open RAN

• RAN virtualization (general-purpose radios + software)
• Vendors: Mavenir, Parallel Wireless, Rakuten Symphony
• Challenge: performance compared with traditional RAN
• Adoption: challenger operators, DISH (USA), Rakuten Mobile (Japan)

Operator security

• Large-scale DDoS mitigation (>1 Tbps capacity)
• BGP security: RPKI, ROA, BGPsec
• Lawful Interception (LI): CALEA/ETSI infrastructure
• 24×7 SOC with threat intelligence
• CESTI (France) or LEMP (ETSI) compliance

Regional ISP budget

• Core with 2× MX960 + 4× ASR 9006: ~€12M excluding VAT
• GPON OLT access across 30 POPs: ~€8M excluding VAT
• DDoS infrastructure: ~€3M excluding VAT
• BSS/OSS: ~€5M excluding VAT
• Peering + transit: ~€2M/year
• Total: €30-50M project cost + opex
