Integrated Multiple Service Access Node

iBAS MULTIService Access Platform

IBAS constitutes the INTRACOM TELECOM answer to the Next Generation Multi-Service Access Node (MSAN) needs of the ambitious Telecommunications Operator.

Constituting part of the INTRACOM TELECOM Access System (IAS) platform, IBAS is specially designed for the provision of multiple Broadband (High Speed Internet) and Narrowband (Voice, Leased Line) services concurrently from the same chassis, taking full advantage of xDSL technologies and ATM and/or Ethernet transmission backbone.

IBAS provides ADSL, ADSL2/2+/RE-ADSL, G.SHDSL, POTS, ISDN-BRA and TDM-SHDSL services from the same chassis and can be connected to a PSTN Switch via a V5.2 multilink interface, to an ATM network via up to 2 ATM-155, up to 4 E3 ATM interfaces or to a Metro Ethernet network via 1 or 2 GbE interfaces. It can also provide cascade ATM-155, ATM-34 or IMA interfaces to ATM-based DSLAMs, GbE or FE interfaces to Ethernet based DSLAMS or TDM Ε1 interfaces to V5.2 access multiplexers.

Further to the above an additional industry leading feature of the IBAS MSAN platform is that it can accept Wireless Access Line Cards. This capability enables IBAS to satisfy needs for Wireless Broadband Access services and Wireless Backhauling requirements. For further information on these aspects of the IBAS MSAN platform please refer to the WiBAS family of solutions.

Voice can be provided using V5.x interface to a Legacy PSTN Switch. Further to V5.x full support of VoIP over Ethernet or over AAL5 over ATM is provided using in both cases H.248/MeGaCo signalling constituting a full-service access system.

Available in various versions meeting both European ETSI and American ANSI specifications, the IBAS MSAN has been especially engineered for efficient outside plant cabinet installation. Combined with the in-house designed and developed sophisticated series of INTRA-S and INTRA-D metallic cabinets, the IBAS MSAN offers an integrated, environmentally hardened and exceptionally durable solution for access ring deployments.

IBAS MSAN is supported by the BBMS (Broad Band Management System) element management system. BBMS is part of INTRACOM TELECOM element management portfolio of products dedicated to the rapid deployment, efficient supervision and unified management of INTRACOM TELECOM's Multi-Service Access Node IBAS MSAN as well as of INTRACOM TELECOM mini-DSLAM and FlexAccess product families. Please refer to the relating BBMS brochure for further information.

The modular and highly reliable system architecture of the IBAS MSAN provides flexible, fast and cost-effective adaptation to present customer needs, in addition to expansion and upgrade capabilities for the support of future service requirements.

IBAS as Multi-Service Access Platform used in Gigabit Ethernet Ring deployments
Providing true Triple Play NGN services

IBAS, having the capability to provide both legacy narrowband and broadband services, is used as the "corner stone" of Next Generation Access Network.

IBAS, supports ring configuration by forming Gigabit Ethernet Rings supporting Resilient Packet Ring protection mechanism.

Broadband Ethernet traffic is transmitted over the GbE ring, effectively transforming the chain of point-to-point links between nodes to a true shared media that enables efficient statistical multiplexing of burst traffic and spatial reuse.

An Edge Device lying on the edge of a CDN (Content Delivery Network) under the control of a Content Provider allows the Content Provider to provide its customers with ancillary services such as Video and Music delivery.

Video broadcasting is supported efficiently by "moving" IGMP awareness and Multicasting capability towards the edge of the network thus integrating it on the IBAS MSAN.
A Set Top Box at the subscriber's premises connects the subscriber's TV to the incoming digital TV signal.

The remote IBAS system terminates POTS and ISDN lines and acts as an H.248 Access Media Gateway. Alternatively, in case legacy TDM switches have to be utilised, voice traffic is terminated at the remote ONU and concentrated to V 5.2 links, which are transported over the Ethernet ring employing TDMoIP techniques.

Furthermore, TDM leased lines are supported employing TDM over IP techniques.

At the OLT side the optical ring is terminated by an IBAS OLT system. The RPR rings are terminated providing GbE to the Metro Ethernet Network and G.703 2Mbps links to Leased Line Network and/or Digital Exchange.
