RAD's LA-104 leverages existing copper
and ATM infrastructures to provide broadband data and voice convergence over
RAD?s Link Access (LA) family of ATM Integrated Access Devices (IADs)
enables carriers to deliver multiple services, such as voice, LAN and data,
to small and medium-sized enterprises (SMEs) over a single DSL access line.
Carriers use the existing ATM network and DSLAMs to supply these converged
services. This improves network utilization and eliminates the need to
invest in new infrastructure, thereby achieving increased profitability.
Based on ATM, the IADs guarantee Quality of Service and end-to-end
management up to the customer premises.
Leased Lines over ATM (LLoATM) ? Employing AAL1 constant bit rate (CBR)
traffic enables the IADs to support Quality of Service (QoS) with
reliability for mission-critical applications, end-to-end across the
network. This provides leased line services at a fraction of the cost of
leasing E1/T1 lines. E1/T1 or serial data interfaces support any type of
user interface and guarantee the same Quality of Service as TDM-based leased
line services. Enterprises requiring fat ATM pipes at headquarters can build
a network combining lower speed DSL at branch offices and higher speed ATM
service at the main office using ATM NTUs (such as RAD?s ACE ATM access
units). With support for structured data, the carriers can build a network
with smooth migration from SDH to ATM backbones.
VoDSL ? By supporting voice over DSL per the Loop Emulation Service (LES)
standard, the Link Access IADs enable carriers to deliver toll quality voice
and data services over the ATM backbone. They support FXS or ISDN BRI ports
or a single PRI port over ATM using AAL2. They work together with existing
telephone equipment including fax machines, modems and analog telephones.
The user continues to receive Class 5 services such as caller ID and call
waiting. G.726 voice compression with VAD increases the amount of bandwidth
that can be used for data traffic.
Frame Relay ? Support for Frame Relay interworking (FRF.5) and service
interworking (FRF.8) over ATM using AAL5 allows business users to upgrade
their services without large investments. Carriers can migrate their
customers? services to the ATM network with its guaranteed bandwidth
capabilities while preserving the existing Frame Relay architecture.
LA units incorporate a fully featured, built-in IP router or bridge. The
integrated IP router saves the costs of an external router and provides an
excellent solution for LAN-to-LAN or Internet access services. NAT
functionality allows multiple users to share a single public IP address.
Additionally,the LA-110 has an integr ated firewall and supports VLAN
Network Management Reduces Expenses
The IADs feature superior management capabilities through a local terminal,
Web-based interface or remotely by using Web-based Telnet or SNMP network.
RADview SNMP management software supports large networks in a simplified
way. Comprehensive diagnostics and statistics allow full control and
monitoring of the units, resulting in reduced operational and maintenance
ATM Quality of Service (QoS) Ensures End-to-End Control
Link Access IADs provide ATM QoS so the carrier can deliver all voice and
data services with QoS guarantees. Traffic shaping per VC secures the
priority of critical applications. Operation, administration and maintenance
(OAM) cells provide complete end-toend control of the network. They enable
fault notification and performance and connectivity monitoring, including
Easy Installation and Operation Reduces Operating Expenses
Plug-and-play units facilitate installation. Simple software and
configuration upgrades enable the communications service to grow together
with the customer?s business, without the need for new hardware.
