How the iAN8K B1000 fits into a Triple Play Delivery Mechanism

• B1000 provides all the requirements for efficient and economic delivery of Triple Play Services– High Bandwidth Subscriber Interfaces– High Throughput Network Interfaces– High Availability Architecture– Efficient Multicast Architecture– Stringent QoS mechanisms– Advanced Session Management Techniques– Integrated VoIP Gateway– Security and Authentication Mechanisms.


Subscriber Intefaces

• High Bandwidth Subscriber Interfaces– Triple Play offerings will require substantially higher B/W per

subscriber to be able to offer high bandwidth/ multiple channels of HDTV or SDTV• Variety of high bandwidth subscriber interfaces like ADSL2+,

VDSL2 and GEPON.

• Advanced DSL technologies like Pair Bonding, READSL2 and OLR to ensure carriers maximum geographical coverage at required high bandwidth rates.

• The iAN8K B1000 DSL Line cards support line rate throughput @ 1Gbps per line card


Network Interfaces

• High Throughput Network Interface– The network traffic in a high density DSLAM with Triple Play offering

is very high and it is imperative that the DSLAM does not become the bottleneck.• The iAN8K B1000 configured with 2 ICM3G mode provided 7 *

uplink Interfaces from the DSLAM.


Reliability

• High Availability Architecture– With the DSLAM catering to multiple commercial services offerings,

high availability and reliability become a critical factor in the service offering.• High availability redundant architecture for the controller ICM3G

and future N+1 redundancy architecture for the line cards


Multicast

• Efficient Multicast Architecture– IP Multicast is one of the core technology that enables services like

IPTV by increasing network efficiency.• Multicasting is done at the ICM3G and on the line cards to ensure

that no unwanted bandwidth is utilized on any network links.

• ICM3G supports 1024 Multicast Groups

• IGMP Proxy and PIM-SM in addition to IGMP Snooping v1/ v2 / v3

• Implements an IGMP aggregation mechanism whereby Join/Leave messages are aggregated before being passes on to the uplink routers.

• The iAN8K B1000 support IGMP fast leave option that helps fast channel zaps enhancing the users’ QoE (Quality of Experience).

QoS

• Stringent QoS mechanism– End to End guaranteed QoS mechanisms are mandatory to

ensure predictability of services offered.• Capability to ensure that up to 2048 traffic flows originating

to/from the subscriber can be uniquely identified, classified and accorded appropriate treatment as per SLAs– The flow Classification based on VLAN, MAC address, IP

address, DSL port, protocol, and Ethernet type– Ability to define action per flow

• Supports multiple PVCs per port (Up to 8 / DSL port). • Rate limiting capabilities on downstream traffic• Advanced scheduling mechanisms – Strict priority,

WRR,WFQ, WRED• VLAN Stacking for Enterprise applications.


Session Management

• Advanced Session Management Techniques– One of the most important requirements for offering commercial triple

play services is the ability to uniquely identify a subscriber session so as to uniquely manage it based on SLAs.• DHCP Option 82• PPPoE intermediate relay for inserting Subscriber Identification• DHCP/PPP snooping is also supported to build IP/MAC address list• Video service management features like rate control on each

channel, maximum duration for each preview, maximum number of previews, and blackout duration after each preview etc.

• Channel access control - three levels of access to each video channel: full, limited, and not allowed

• Multicast authentication locally in the system• Viewing statistics in form of session records for accounting and

billing


Voice Access Gateway for NGN Solutions

• Integrated Voice Gateway (iFXS)– The iAN8K B1000 offers an integrated Voice Gateway function

with the iFXS module providing carriers the option to convert traditional 2 wire POTS interface to VoIP at the Edge Network• Supports SIP, and MEGACO(H.248) in near future• Detects fax and modem tones, disables any voice

processing (echo cancellation), and passes through the modem signal as G.711 PCM.

• Supports voice activity detection (VAD) silence suppression/regeneration and comfort noise generation.

• Supports transcoding between A-Law and µ-Law. This feature is useful between interconnecting carriers.

• Supports DTMF tone relay, DTMF Tone detection and generation

• Support T.30/T.38 FAX relay


Major VoIP Features

• Support for G.711, G.729a, G.726, and G.723• Support VAD (silence suppression) and CNG• Support echo cancellation (G.168) - 16ms echo tail length• MGCP, H248 in MSAN application , SIP protocol in MSAN• Out of Band DTMF (RFC2833)• Call Forwarding• Call Holding• T.38 Fax Relay• Incoming Call Barring


Security

• Security and Authentication mechanisms– Ensuring that paid services like IPTV and VOD are not accessed

by unauthorized users is of critical importance to the service providers to maximize revenues.• Unique local multicast authentication mechanism that ensure

that non-STB users do not access multicast channels.• Other security mechanism –both direct and indirect include

– Up to 2048 ACLs (ICM3G); Up to 172 ACLs (LC)– DSL port isolation– Configurable learned MAC address ageing time– Configurable DLF threshold– Semi-static MAC address learning – Anti MAC and Anti IP address spoofing– IP policing– Broadcast and Multicast rate limiting – Per port MAC Address and IP Address limit


Network Management Features

• Management Features– In-band and out-of-band management– RS232 based console– User Access control– SNMPv2 Agent– Cisco like CLI– Built-in Telnet server– TFTP client and server– SSH support on ICM3G– Fault and performance management– System log– Remote CPE management– Stacking support and single IP for stacked units

• EMS Platforms– Netman 4000


Management Options

• Integrated management with Netman 4000• Serial CLI• Telnet CLI• SNMP v1/v2• TFTP Firmware Upgrade, Config Backup/Restore• In band / Out band Management• Management VLAN• Single IP Management for Cascaded System• Access Control
