ATM Services Card
The ATM Services Card from Alcatel provides ATM service adaptation and
inverse multiplexing over ATM (IMA) for 3600 MainStreet Bandwidth Managers.
Installed in any universal card slot (UCS), the ATM Services Card adapts low
speed, legacy services to ATM cells for transmission through a multiservice
broadband network.
The 3600 system is the world's best-selling T1/E1 bandwidth manager for
managed voice and data services. The 3600 system provides integral support for:
- analog, digital and ISDN BRI/PRI voice
- n*56/64 kb/s leased lines
- subrate data (DDS, X.50)
- packets (HDLC, X.25)
- frame relay
With the ATM Services Card, a simple node upgrade provides a cost-effective
integration strategy to extend proven, mission-critical legacy services into the
broadband world. Network consolidation reduces costs and complexity, and
improves operational efficiency. Service users continue to receive the same high
quality of service as set out in their service level agreements (SLAs), while
service providers benefit from a significant increase in network efficiency.
Extending broadband benefits to legacy services
The ATM Services Card allows corporate networks to exploit tariff
differentials that favor ATM. The card is also a tremendous benefit where WAN
connectivity requirements exceed T1/E1 capacity, but are not high enough to make
DS3/E3 lines an economical choice. The ATM Services Card is optimized to support
a single ATM aggregate comprised of one to four inverse multiplexed T1/E1 links.
Installing the ATM Services Card in 3600 Bandwidth Managers increases network
efficiencies, as operators manage only one logical "pipe" ranging from
1.5 to 8 Mb/s, instead of parallel, discrete T1/E1 links. Consolidation onto a
single pipe also reduces the potential for the bandwidth fragmentation inherent
in multiple T1/E1 links.
Two variants of the ATM Services Card are available. The first variant, the
ATM Services Card AAL1, provides AAL1, cell multiplexing and n*T1/E1 aggregates,
where n = 1, 2, 3 or 4. Network access is provided via the n*T1/E1 physical
links, which are inverse multiplexed according to the ATM Forum's IMA
specification.
A second variant of the ATM Services Card, the ATM Services Card AAL1/5,
provides both AAL1 and AAL5 Service Adaptation.
By using the 3600 Bandwidth Manager to adapt established and proven
narrowband services to broadband as close to the customer location as possible,
service providers are able to increase access to their ATM core infrastructures.
The n*T1/E1 aggregate accommodates an infinite mixture of traffic types, and the
ATM quality of service parameters ensure each traffic type is given and achieves
the required service level.
