Alcatel-Lucent 7750 and 7710 Service Routers
A T M M E D I A D E P E N D E N T A D A P T E R
The Alcatel-Lucent Service Router (SR) ATM Media Dependent Adapter (MDA) provides industry-leading service
density and rich connectivity options in a wide range of service and application solutions for service providers,
cable MSOs, and enterprise customers.
The Alcatel-Lucent ATM MDAs are
available on the 7750 SR and 7710 SR,
are fully suppor ted by the AlcatelLucent 5620 Service Aware Manager
(SAM), and support in-service insertion
and removal. ATM MDAs are supported
in MDA slots on the 7750 SR-1 and on
the 7750 SR-7 and 7750 SR-12 using
Input/Output Modules (IOMs) with up
to two MDAs per IOM. Select ATM
MDAs are supported on the AlcatelLucent 7750 SR-c12 and 7750 SR-c4
using MDA Carrier Modules-XP
(MCM-XP) with one MDA provisioned
per MCM-XP. Select ATM MDAs are
also supported on the Alcatel-Lucent
7710 SR-c14 and 7710 SR-c4 using MDA
Carrier Modules (MCM) with one MDA
provisioned per MCM.
The ATM feature support on the
Alcatel-Lucent Service Router portfolio
consists of a full set of flexible and
scalable ATM connectivity options
that complement a comprehensive
set of ATM traffic man agement and
oper ations, admini stration, and
maintenance (OAM) functions.
With the ATM MDAs, network operators
are able to leverage a rich and proven
ATM feature set and combine it
with the leading service, packet level
hierarchical quality of service (H-QoS) and
OAM capabilities of the Alcatel-Lucent
Service Router Operating System
(SR OS) to activate a new breed of rich,
high-performance services over ATM
access methods. ATM MDAs can be
used with any of the following Layer 2
and Layer 3 services:
• ATM virtual private wire services
(VPWS) with support for ATM user-tonetwork (UNI)/network-to-network
(NNI) switching, ATM N:1 cell mode
pseudowire over IP/MPLS and ATM
adap tation layer 5 (AAL5) service
data unit (SDU) mode pseudowire
over IP/MPLS
• ATM virtual circuit (VC) termination
on a virtual private LAN service (VPLS)
• ATM VC termination on an Internet
enhanced service (IES)
• ATM VC termination on a virtual
private routed network service (VPRN)
• ATM virtual trunks over IP/MPLS
for tunneling private network-tonetwork interface (PNNI) switched
services over an IP/MPLS network
• ATM/Frame relay (FR) network
inter-working (Frame Relay
Forum 5 [FRF.5]) VPWS with both
local switching and remote switching
over a pseudowire
• ATM/FR/Ethernet service inter working
VPWS with both local and remote
switching over an Ethernet pseudowire
• ATM/FR/Ethernet service inter working
VPWS which allows IP connectivity
over an IP PW between different link
layer technologies
• PW switching removes the need for
a full mesh of tunnels and signaling
adjacencies
• All VPWS and PW types are per
IETF PWE3 RFC standards
Features and benefits
• Leading interface density:
¬ Up to 320 ATM OC-3c/STM-1c or
80 OC-12c/STM-4c interfaces per
Alcatel-Lucent 7750 SR
¬ Up to 24 OC-3c/STM-1c/OC-12c/
STM- 4c interfaces on the
Alcatel-Lucent 7710 SR
• Maximized configuration flexibility
and optimized interface slot utilization
through the use of ATM small
form factor pluggable (SFP) optics
• A highly scalable hardware implementation capable of supporting up
to 8000 VC/ VP endpoints per MDA
• Support for ATM routed encapsulation
and routed bridged encapsulation
termination on IES and VPRN services
• Granular per VC, VP and port ATM
statistics as outlined in RFC 2515
• Leading QoS capabilities:
¬ A comprehensive set of ATM traffic
management capabilities that
complements an industry-leading
H-QoS, including:
– ATM service categories:
- constant bit rate (CBR)
- variable bit rate – real-time
service category (rt-VBR)
- variable bit rate – non-real time
service category (nrt-VBR)
- unspecified bit rate with
minimum cell rate support
(UBR + MCR)
– per VC queuing with strict
priority scheduling for real-time
service categories and weighted
round robin scheduling for
non-real-time categories
– per VC and per virtual path (VP)
shaping
– per VC/VP ingress policing with
support of partial packet discard
(PPD) for AAL5 VCs
• Leading OAM capabilities:
¬ OAM F5 support at the VC level
and F4 support at the VP level
– OAM F5 alarm indication signal
(AIS)/remote defect indication
(RDI) generation, termination on
all VCs simultaneously
– OAM F5 loopback launching and
terminating options support
– ATM ping OAM loopback enables
the continuous oper ation of an
ATM OAM F5 loop back to notify
an operator of loss of connectivity
of an ATM customer interface
terminating on an IES and VPRN
service
¬ ATM ILMI 3.1 and 4.0 to facilitate
the managing and monitoring of an
ATM interface, ATM MDAs support
Integrated Link Manage ment
Interface (ILMI) 3.1 and ILMI 4.0,
with the ability to automatically
negotiate the ILMI version
¬ Option to terminate or transparently
generate ATM OAM traffic over an
ATM pseudowire
¬ VCCV ping to check PW connec-
tivity and validate the user plane
against the control plane for the
PW FEC
¬ OAM tools for services with ATM
endpoints include LSP Ping, LSP
Traceroute, SDP Ping, VPLS MAC
Ping, VPLS MAC Trace, IP-VPN
VRF-Ping and IP-VPN VRF-Trace,
and Service Ping
¬ ATM service mirroring includes
mirror sources with ATM access
circuits as part of ATM AAL5 SDU
VPWS, Ethernet and IP interworking
VPWSs, VPLS, IES and VPRN services
• Leading high availability capabilities:
¬ 1+1 Automatic protection
switching (APS), single chassis
and multi- chassis modes, are
supported on ATM MDAs, as
defined by ITU-T G.841 and
GR-253-CORE, to main tain existing
SLAs when services are converged
over an IP/MPLS backbone
¬ Non-stop services: all services
with access circuits on the ATM
MDA are fully hot redundant for
both the configuration and state
achiev ing a hitless switchover
from the active to the standby
control plane module
¬ PW types which support access
circuits on the ATM MDA provide
PW redundancy feature to protect
against IP/MPLS network failures
and remote access circuit failures
