AT-iMG626MOD |Outdoor Ethernet intelligent Multiservice Gateway

Firewall Capability

The AT-iMG626MOD has an integral Stateful
Inspection Firewall with Network Addess
Translation (NAT),Denial of Service (DoS) and
an Intrusion Detection System (IDS) with
blocking to protect end-customer networks.

Reducing Operational Cost

Value,Versatility,and Validation

The AT-iMG626MOD will support many
different types of deployments senarios.Using
theAlliedView NMS, the iMG can be auto-
configured during its initial power on sequence,
further reducing the need to ‘touch’the device
during service provisioning and therefore
reducing the service provider’s operational
expenditure (Opex).
With a modular HPNA LAN interface,the iMG
can provide connectivity via existing customer
premises (inside) wiring,reducing the costly and
time consuming rewiring jobs.
Amodular WAN interface,enables the service
provider to use the same system and configure
it for different access networks.Fur ther
extending its value and reducing the service
provider’s opex,the AT-iMG626MOD offers
testing and fault-isolation on the Ethernet,
HPNA and POTS ports,that assist the service
technician to quicklypinpoint the solution when
troubleshooting a problem.

Management

Easy to Deploy and Manage

With the AT-iMG626MOD customer premises
deployment has never been easier.The
AT-EN646MOD Outside Plant Enclosure may
be pre-installed.It accommodates fiber
termination and grounding for the iMG. When
services are ordered,the AT-iMG626MOD
electronics chassis mounts easily into the
enclosure,and terminates in-home wir ing and
power connection.

AlliedView NMS

The AT-iMG626-MOD is designed to be easy
to deploy and manage.With the AlliedView
NMS software platform,the AT-iMG626MOD
can be automatically provisioned and managed
remotely.The NMS provide secure
authentication and registration with intelligent,
automatic configuration of remote iMG units,
and seamless integration via XML/SOAPwith
service providers’ existing OSS platforms.
