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)
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.
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.
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 net-
work 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.
