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.
