LA-110

Integrated Access Device

LA-110’s multiservice support enables users to

use widely-available, cost-effective DSL

infrastructure to replace expensive legacy leased

lines.

Pseudowire emulation

LA-110 transports TDM, ATM, HDLC, and Frame

Relay data transparently over packet switched

networks (PSNs). Payload encapsulation is

performed using standard methods, including

SAToP, CESoPSN, TDMoIP, ATMoPSN, HDLCoPSN,

or FRoPSN. Pseudowire emulation enables

carriers to provide high revenue leased line and

cellular backhaul services over IP DSLAMs and

PSN.

Frame Relay

The LA-110 supports Frame Relay services using

network interworking (FRF.5) and service

interworking (FRF.8) over ATM. This allows

carriers to migrate their customers’ services to

the ATM or PSN network while preserving the

existing Frame Relay architecture.

IMA bonding

To increase the bandwidth capacity of available

SHDSL lines, the LA-110 features optional IMA

(inverse multiplexing over ATM) bonding over

four × 2-wire SHDSL lines. This allows carriers

and service operators to cost-effectively fill the

bandwidth gap between lower speed xDSL and

higher speed fiber, providing up to 9.2 Mbps for

distances of up to 8 kilometers (5 miles).

Traffic management over PSN

Traffic management enables carriers to better

manage the end customer’s application through

prioritization of the data streams. Traffic

classification is based on 802.1p, DSCP, ToS, or

IP Precedence. Traffic can be mapped into three

different connections or into different queues in

a single connection.

IP functionality

The LA-110 incorporates a fully-featured, built-

in bridge or IP router with integrated firewall.

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. Layer 2 VLAN

mapping is also supported.

ATM quality of service and OAM

Supporting ATM QoS, the LA-110 enables

carriers to deliver voice, data and leased line

services with performance guarantees. Traffic

shaping per VC secures the priority of critical

applications, with service classification per CBR,

VBR, UBR, and UBR+ bandwidth profiles.

Additionally, operation, administration and

maintenance (OAM) cells provide complete end-

to-end control of the network. They enable fault

notification and performance and connectivity

monitoring, including delay measurements. The

LA-110’s comprehensive diagnostics and

statistics collection allow service providers to

reduce their operational and maintenance costs,

by minimizing technician truck rolls for on-site

inspections to localize and repair network faults.

Network management

The LA-110 features flexible management

capabilities, including local management via an

ASCII terminal (RS-232). In addition, remote

management can be performed either inband or

out-of-band, using the network or user ports.

Advanced FCAPS (Fault, Configuration,

Accounting, Performance, Security) and

diagnostic tools are provided by

RADview-EMS, RAD’s carrier-class element

management system, via an SNMP-based GUI.

The LA-110 also supports a variety of

configuration access channels, including Telnet,

SNMP, Web server, and TFTP. Incorporated

security features include Secure Shell (SSH),

Web-based Secure Socket Layer (SSL), SNMPv3,

and RADIUS.

RAD’s LA-110 ATM IAD enables carriers to

converge multiple services, such as voice, data,

and Internet access, over DSL access lines and

existing ATM or packet-based networks. This

improves network utilization and eliminates the

need to invest in new infrastructure, thereby

achieving increased profitability. Typically used by

small and medium-sized enterprises (SMEs) and in

cellular backhaul, the LA-110 features a variety of

network interface alternatives, including ADSL,

SHDSL, IMA over SHDSL, and E1. User interfaces

include 10/100BaseT and optional E1 (TDM or

UNI), ISDN, or serial FR/X.21/V.35.
