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
authorities.
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
housing.
