MileGate je fleksibilna pristupna i transportna platforma koja obezbeđuje Ethernet i TDM saobraćaj u jednoj šasiji. Povezivanje korisnika i pristupnih tačaka je moguće preko bakarnih parica i optičkih vlakana. MileGate ima hibridni TDM i Ethernet backplane čiji su slotovi međusobno povezani sa 10GBE i na taj način obezbeđuje visoke performanse za Ethernet servise. MileGate pruža tradicionalne servise, kao što su analogna telefonija, sinhroni i asinhroni data servisi malih kapaciteta, E&M, E1 servisi i nove NGN servise,Triple Play, FTTC, FTTB, FTTH (FTTx – Fiber to the x).
MileGate platformu odlikuje veliki broj interfejsa:
• DSL (ADSL2plus, VDSL2, SHDSL EFM/ATM/TDM)
• Ethernet (100BaseT, 100BaseFx, GbE, 10GbE)
• SDH interfejse (STM-1, STM-4)
• Data (G.703, X.21, V.35, V.24,..)
• Interfejsi zatelefone (POTS, ISDN, E&M)
MileGate platformu odlikuje visoka pouzanost (99,999%), poboljšani temperaturni opseg rada (-25 °C do +60 °C), mogućnost povezivanja 3800 DSL korisnika ili 1920 optičkih korisnika po jednoj 19 “ šasiji.
Izdvajamo sledeće MileGate proizvode:
MilGate 2500
MileGate 2500 je dizajniran za centralne lokacije (CO), kao i za ulične kabinete da bi obezbedio različite voice, data i NGN servise.

Maksimalna raspoloživost je garantovana dodavanjem redundantne centralne kartice i medija gejtvej uređaja. Šasija ima 8 slotova od čega je 7 namenjeno za servisne kartice.
MileGate 2011
Mikro DSLAM namenjen za FTTB mrežnu topologiju.Dizajniran je da se instalira u podrumima i zajedničkim prostorijama u zgradama. Terminira optičko vlakno i konvertuje optički signal u električni. Sa VDSL2 interfejsima može se povezati 8 korisnika preko postojećih telefonskih parica. Sa propusnim opsegom preko 100 Mbps po VDSL2 interfejsu, MileGate 2011 može obezbediti moderne Triple Play servise, kao što su IPTV , VoD i VoIP bez potrebe polaganja optičkih vlakana do svakog stana.
Opciono, MileGate 2011 može konvertovati analogni i digitalni CATV signal i emitovati ga u postojeću koaksijalnu kablovsku infrastrukturu. Stoga, mrežni operatori mogu ponuditi tradicionalne CATV i moderne IPTV servise istovremeno.
Modemi za Milegate
Za povezivanje korisnika preko bakarnih parica koriste se standardni ADSL, ADSL2plus, VDSL2 modemi, kao i modemi za biznis korisnike koji obezbeđuju simetrične brzine: lineRunner SHDSL DTM, LineRunner SHDSL DTU, LineRunner SHDSL EFM DTR…
MileGate – One access platform for all your needs
MileGate combines carrier-grade broadband access, telephony and data interfaces in one single, compact IP/Ethernet-based Multi-Service Access Platform.
As a result, network operators can continue to support traditional telephony and broadband services, migrate to the NGN (Next Generation Network) and provide Triple Play and broadband business services, too. MileGate comes with a hybrid backplane that enables the simultaneous deployment of TDM- and IP/Ethernet-based services, and ensures a smooth migration of voice and data services.
With the three available subrack sizes MileGate 25×0, MileGate 2310, MileGate 2200, and the Micro-DSLAM MileGate 2011, network topology can be designed flexibly. Operational in a wide range of temperatures and with a robust design, MileGate subracks can be used in street cabinets – however extreme conditions are. The innovative access platform MileGate has been developed for a wide range of electrical (xDSL, telephony) and optical subscriber interfaces. With this flexibility MileGate supports installations in central offices with thousands of subscribers as well as in all FTTx (Fibre-to-the-x) network architectures.
MileGate provides all services with high port density in FTTC applications. From a MileGate 2510 subrack, up to 960 with vectoring extended VDSL2 ports can be provided.
For FTTH (Fibre-to-the-Home) and FTTB (Fibre-to-the-Building) applications KEYMILE provides a specific solution for optical networks: The MileGate Fibre Series supports both active and passive optical Ethernet via one single platform simultaneously.

MileGate – The System Family
MileGate 2500/2510 for CO applications
MileGate 2500/2510 is designed to provide various voice and data and NGN services in central offices, collocation space as well as in street cabinets.
Maximum availability is guaranteed with fully-redundant core units and media gateways.
The subrack provides 21 slots, 20 of which can be fitted with line cards to grant any required service mix. Depending on the selection of line cards e.g. up to 1280 ADSL2plus interfaces can be implemented.
MileGate 2310 – Compact Subrack for multi-service in tight spaces
MileGate 2310 provides the same multi-service flexibility as MileGate 2500/2510 – all MileGate cards can be used. The compact subrack is designed for installation sites, where space is the limiting factor, e.g. in equipment rooms of buildings or in street cabinets.
Maximum availability is guaranteed with fully-redundant core units and media gateways.
The subrack provides 8 slots, 7 of which can be fitted with line cards to grant any required service mix.
MileGate 2200 – Mini-DSLAM subrack for cost-efficient access in sparsely populated areas
MileGate 2200 has been designed for use in street cabinets. At just two height units tall, it can also be installed where space is very limited. As a result, MileGate 2200 is the ideal solution for expanding broadband services in sparsely populated areas.
The subrack offers 4 slots, 3 of which can be fitted with line cards of the MileGate platform that have access to the GbE star. Depending on choice, up to 192 ADSL2plus, 144 VDSL2 or 72 GbE interfaces can be implemented.
MileGate Fibre Series – the access platform for active and passive optical networks
The MileGate Fibre Series is superb for FTTH/B applications and supports both active and passive optical Ethernet via one single platform simultaneously. Based on the MileGate 2510, the MileGate Fibre Series provides easy fibre management as well as fast and easy access for operation and maintenance. Lab-tested EMC makes operation reliable also when operated without cover. Via a redundant core unit MileGate Fibre Series offers top availability in hot-standby mode
MileGate 2011 – The Micro-DSLAM for FTTB Network Achitektures
MileGate 2011 is a Micro-DSLAM for FTTB connections.
It is designed for the operation in basements or in utility rooms in multi-tenant buildings. There the optical fibre is terminated in the MileGate 2011. It converts the signals received from the optical fibre into electrical signals. With the VDSL2 interfaces up to 8 subscribers can be connected to the optical fibre network over the existing telephone cabling.
With a bandwidth of over 100 Mbps per VDSL2 interface, MileGate 2011 can provide modern Triple Play services, like IPTV (TV via Internet) in HD quality, VoD (Video on Demand) and VoIP (Voice over Internet), without the need to bring the optical fibre up to every subscriber in the building.
Optionally MileGate 2011 can convert an analouge and digital CATV signal and feed it into the existing coaxial in-house cabling. So network operators can provide traditional CATV and modern IPTV services in parallel.
