Multiservice Access Platforms (MAPs)
Alcatel 3600 MainStreet Multiservice
Bandwidth Manager
The Alcatel 3600 MainStreet Multiservice Bandwidth Manager is a flexible, scalable and intelligent networking node that combines the functions of an integrated voice and data multiplexer, a frame relay and X.25 switch, a low capacity ATM access node, an intelligent channel
bank, and a digital cross-connect switch. The Alcatel 3600 MainStreet Multiservice Bandwidth Manager accommodates network evolution and protects investment by enabling customers to integrate narrowband legacy services and broadband or IP-based networks.
The Alcatel 3600 MainStreet Multiservice Bandwidth Manager is ideal for access networks that support multiple TDM and packet/cell services, including:
>Packet/cell: ATM, frame relay, voice over frame relay (VoFR), X.25
>TDM: leased lines, voice, data, and voice compression
Offering a wide range of advanced business services, the Alcatel 3600 MainStreet Multiservice Bandwidth Manager is the most successful digital overlay platform ever built, with over 180,000 nodes installed worldwide, and growing.
The Alcatel 3600 MainStreet Multiservice Bandwidth Manager can be used:
>To concentrate circuit-switched, packetand cell-based voice and data traffic
>To offer leased line services – from subrate to 2 Mb/s (n*64 kb/s)
>As an international gateway, providing E1/T1, E3/T3 and ISDN interfaces with signaling and superate conversion, line and circuit grooming and voice compression
>As a lowto medium-capacity 3/0 and 1/0 digital access and cross-connect system (DACS)
>As an intelligent channel bank
Alcatel 3600+ MainStreet Multiservice
Bandwidth Manager
The Alcatel 3600+ MainStreet Multiservice Bandwidth Manager builds on the highly successful architecture of the Alcatel 3600 MainStreet Multiservice Bandwidth Manager. It provides a scalable option to meet the increasing demand for multiple services and higher bandwidth on a single platform. In addition to offering all of the capabilities of the Alcatel 3600 MainStreet
Multiservice Bandwidth Manager, the Alcatel 3600+ MainStreet Multiservice Bandwidth Manager offers fiber optic and electrical interfaces at STM-1/OC-3 speeds. It supports a wide range of circuitand packet-based voice and data services, and is fully compatible with the Alcatel 3600 MainStreet Multiservice Bandwidth Manager, providing seamless integration into existing networks and protecting equipment investment.
The Alcatel 3600+ MainStreet Multiservice Bandwidth Manager is ideal for access networks that support multiple services, including packet and TDM with the requirement for connection to higher speed fiber optic backbones and
metropolitan area networks/wide area networks (MANs/WANs).

MainStreet Business Access Portfolio
The Alcatel 3600+ MainStreet Multiservice Bandwidth Manager supports a diverse set of access technologies including:
>Packet/cell: ATM, frame relay, voice over frame relay (VoFR), X.25
>TDM: leased lines, voice, data, and voice compression
>Synchronous optical network /synchronous digital hierarchy (SONET/SDH): linear interface (STM-1/OC-3), 1+1 interface (STM-1/OC-3), unidirectional path switched ring (UPSR) ring mode (STM-1/OC-3)
An Alcatel 3600 MainStreet Multiservice Bandwidth Manager or Alcatel 3600+ MainStreet Multiservice Bandwidth Manager system that includes frame relay seamlessly interworks with the Alcatel 7470 MSP and the Alcatel 7670 RSP to provide
an end-to-end frame relay solution — from the customer premises to the network core. These platforms are fully managed by the Alcatel 5620 NM allowing service providers to manage the multiservice environment from a single platform and console. New facilities can be added in seconds, rather than weeks, as more subscribers request service.
Alcatel 3600/Alcatel 3600+ MainStreet
Multiservice Bandwidth Manager Enhancements
MainStreet Frame Relay
The Alcatel 3600 MainStreet Multiservice Bandwidth Manager and the Alcatel 3600+ MainStreet Multiservice Bandwidth Manager platforms offer extensive frame relay services. With the simple and cost-effective addition of a frame relay engine (FRE), packet engine (PE) or frame relay switch with Subrate Interface Module (FRS/SRIM) card, an Alcatel 3600/Alcatel 3600+ MainStreet node provides comprehensive frame relay switching capabilities.
MainStreet Frame Relay is a proven service used extensively in public and enterprise networks throughout the world. It can be used effectively in large or small networks that deploy frame relay alone, or in combination with leased line, X.25 and ATM services. Based on a modular architecture, up to
64 FRE and/or PE cards can be connected across the 100 Mb/s FASTbus to create a high capacity node that is capable of switching 120,000 fps.
MainStreet Frame Relay services include X.25/frame relay/ATM network and service interworking capabilities, subrate frame relay switching, and value-added service capabilities, such as VoFR with QoS, packet fragmentation and reassembly, and DLCI multiplexing.
MainStreet ATM Service
The MainStreet ATM Service cards provide ATM service adaptation and inverse multiplexing over ATM (IMA) for the Alcatel 3600/Alcatel 3600+ MainStreet Multiservice Bandwidth Managers. Installed in any universal card slot (UCS), the ATM Service cards adapt the rich variety of Alcatel 3600/Alcatel 3600+ MainStreet Multiservice Bandwidth Managers supported services to ATM cells for transmission over an ATM network.
The ATM Service cards support AAL1 and AAL5 adaptation. The circuit emulation service (CES) adapts constant bit rate (CBR) traffic (n*64 kb/s) to AAL1 virtual circuits (VCs). The HDLC service adapts HDLC-formatted traffic into AAL5 VCs. The card has four E1 or T1 interfaces (physical ports). Each port provides a user network interface (UNI) to an ATM network and can function as an independent network link, or can be assigned to a logical IMA port for combined transmission.
Extending broadband ATM benefits to the Alcatel 3600/Alcatel 3600+ MainStreet Multiservice Bandwidth Managers, the ATM Services Card allows corporate networks to exploit rate differentials that favor ATM. The card's IMA capability is also a tremendous benefit where WAN connectivity requirements exceed E1/T1 capacity. The ATM Service card is optimized to support a single ATM aggregate comprised of one to four inverse multiplexed E1/T1 links.
