Alcatel Carrier Internetworking Solutions Alcatel 3600 - Manual (Page 6)

The Alcatel 3630 MainStreet PRM offers many applications,
including:
> Voice, data, and integrated voice and data networking
> Point-to-point and drop/insert applications
> Superrate operation, providing connectivity for video
conferencing, interconnecting LANs over the WAN
> Leased bandwidth delivery in the local loop
Alcatel 3612 MainStreet Narrowband Multiplexer
Designed to maximize bandwidth
efficiency, the Alcatel 3612
MainStreet Narrowband
Multiplexer (NBM) reduces
networking costs while delivering high-performance services
that are required for today’s business applications. It manages
expensive access link bandwidth through the use of voice
compression, which provides high quality at very low bit rates,
as well as frame relay switching and encapsulation. It also
offers subrate multiplexing features to further improve
bandwidth utilization.
The system can support various combinations of voice and
high/low speed data, including connections from LAN routers
and up to 24 analog or digital connections. Maximum
bandwidth efficiency is realized with dynamic bandwidth
allocation by sharing bandwidth on demand between voice,
fax and data.
Alcatel 3612 MainStreet NBM highlights:
> Bandwidth savings through efficient multiplexing of voice,
fax and data over leased line, frame relay and ISDN services
from remote locations
> Highly flexible access feeder to multiservice networks
> Central hub for smaller star networks or point-to-point
applications
> Combination of LAN, legacy data (Async, X.25, SNA, etc.)
and voice over frame relay (VoFR) enables substantial
bandwidth savings and performance improvements across
the WAN
> Use of sophisticated low bit rate voice compression
techniques delivers high-quality voice (and fax)
communications while minimizing use of costly bandwidth
> Encapsulation into frame relay of PBX CCS signaling
protocols provides significant bandwidth savings and
provides PBX feature transparency
> Automatic aggregate protection of leased lines over the
switched ISDN network negates the need for expensive,
and often idle, alternate bandwidth for rerouting.
> Flexible ISDN features allow provision of temporary
switched connections for disaster recovery applications
Network Termination Units (NTUs)
Alcatel 2902 MainStreet Network Termination Unit
The Alcatel 2902 MainStreet
Network Termination Unit
(NTU) delivers managed
bandwidth access of up to 2 Mb/s over existing copper pairs
(HDSL) or E1 facilities. Within a single unit, service providers
can deliver integrated data and digital voice access with a
high degree of flexibility and reliability, while making use of
existing network infrastructure.
The Alcatel 2902 MainStreet NTU can be configured to deliver
n*64 kb/s to 2 Mb/s voice and data services over two regular
twisted copper pairs up to 5 kilometers (3.1 miles), without
requiring repeaters.
The Alcatel 2902 MainStreet NTU allows service providers
to multiplex data, router and LAN hub traffic into a single,
versatile gateway. It provides a flexible, cost-effective way
to integrate digital voice and data traffic from a business site
onto a high speed E1 digital link for customer access to public
or private networks, or for point-to-point operation.
