New features for dedicated networks added to KEYMILE’s MileGate

Hanover, October 12, 2011 – In addition to tried-and-tested Ethernet

functions, KEYMILE’s access and transmission platform, MileGate, continues

to incorporate new cards to be able to offer comprehensive TDM data and

voice services. These new units aim to be used primarily in dedicated

networks belonging to railway companies, utility providers and public


KEYMILE, a leading supplier of cutting-edge technology for communications

solutions in access and transmission systems, is significantly expanding the

TDM functionality of its IP-based MileGate platform. The range of interfaces

for this flexible access and transmission platform has been extended to

include additional voice, data, and transport functions for mission-critical

communications networks.

MileGate provides native Ethernet and native TDM services, being the latter

used predominantly in dedicated networks. Thanks to its hybrid Ethernet and

TDM backplane, MileGate can supply legacy services such as analogue

telephony, as well as synchronous and asynchronous TDM connections.

Simultaneously, MileGate also has voice gateways (SIP and H.248) and a CEoP

(Circuit Emulation over Packet) gateway in order to transmit TDM data via an

Ethernet backbone. The support of SDH transport interfaces and EoS functions

(Ethernet-over-SDH) enable smooth transition from TDM to Ethernet.

MileGate’s backplane provides 10 GbE access per slot, which in conjunction

to its modular switching matrix, allows operators of dedicated networks to

flexibly extend MileGate with a variety of different Ethernet functions and

interfaces (optical or electrical).

One of the new expansions is a flexible data interface card for synchronous

and asynchronous data transmission. Per card, this provides four TDM data

interfaces, flexibly configurable as either – V.11/X.24, V.24/V.28, RS-485

or V.35. Various protective and redundancy functions guarantee maximum

availability of the services.

New voice-interface cards are tailor made for telephony demands in dedicated

networks. A POTS FxS card provides 16 analogue interfaces with extended

voltage protection that can be matched with the new FxO interface card

providing analogue trunks. A 2/4-wire voice card with E&M signalling can be

used with voice frequency modems, or other 2/4 wire communication terminals.

The E&M unit offers ample voice conference functions; per card, up to 32

conference participants can be connected in ten groups. The conference

services are fully compatible with other telephony services, e.g. POTS/ISDN

services in UMUX and MileGate.

The new and improved SDH STM-4/STM-1 transmission interface provides the

ability to transport TDM as well as Ethernet traffic over SDH. The EoS

function embedded in the unit is accessible to users via the unit’s front

Ethernet ports, as well as via any other Ethernet electrical or optical

service units in MileGate.

The new cards are now available.

The access and transmission platform, MileGate, is a compact and robust

system with a very high interface density. Together with the extended

operating temperature range of -25°C to +60°C, MileGate is ideal for usage

in dedicated network’s often harsh conditions, for example in an outdoor



KEYMILE is a leading supplier of cutting-edge technology for communications

solutions in access and transmission systems. The flexible and robust

IP-based multi-service access platforms allow telecommunications providers

to supply a variety of voice and data services via copper wire and optical

fibre. Simultaneous availability of IP/Ethernet and TDM technology

guarantees smooth migration to the Next Generation Network. KEYMILE systems

are used for reliable data transmission in mission-critical areas of

telecommunications networks used by railway companies and energy suppliers,

as well as in mobile and professional mobile radio networks. The company has

major business bases in Germany and Switzerland, as well as subsidiaries and

partners worldwide. It has installed systems in more than 100 countries. For
