- MAXcess is a family of scalable, integrated access
equipment that facilitate the transmission of multiprotocol data, voice,
fax and LAN over either Frame Relay, Leased Line, DDS or ISDN services.
MAXcess provides freedom of choice of service and topology, by offering a
scalable solution to corporate networking needs from SOHO to large
- Based on a standard Frame Relay switching
architecture, MAXcess offers dynamic bandwidth allocation. Coupled with
high quality voice compression, MAXcess ensures efficient use of bandwidth
over leased lines, Frame Relay or ISDN services.
- MAXcess utilizes the proprietary Frame Relay+
protocol to send long data frames when possible, and segment them only
when necessary, thus ensuring minimum overhead for voice/data integration.
Frame Relay+ uses standard Frame Relay frames.
- Support of multiple simultaneous applications is
provided using seven user-defined priority levels. The prioritization and
fragmentation mechanism ensures high quality voice, low delay and minimal
- MAXcess supports silence suppression to save
bandwidth by automatically detecting silence and adjusting transmission to
reduce bandwidth consumption.
- MAXcess can encapsulate several voice and data
channels over a single DLCI, in order to minimize the monthly service
charges over public Frame Relay networks.
- MAXcess utilizes advanced voice switching
techniques. It uses routing tables to manipulate the DTMF dialed digits,
thus creating a flexible and user-transparent dialing plan of 3 to 22
digits. Switching the voice calls within the Frame Relay network
eliminates switching via an external PABX, thus saving costs of additional
PABX modules. Voice quality is also improved since there is no need for
- MAXcess is available on four platforms offering the
best solution for specific networking needs:
MAXcess-3000 is a 4U high modular hub, supporting up to 12 I/O
slots, a common logic module and two power supply modules.
MAXcess-3004 is a 2U high modular hub for smaller sites, supporting
five I/O modules, a common logic module and a power supply module.
MAXcess-300 is a compact 1U high,
non-modular access product for the branch office. It provides connection
to four analog or two ISDN-S0 voice/fax channels and six data ports.
Optional LAN port can be used instead of one data port, supporting IP/IPX
MAXcess-30 is a compact desktop
access product for smaller sites such as SOHO, supporting two analog or
one ISDN-S0 voice/fax channels and three data ports. An optional LAN port
can be used instead of a data port, supporting IP/IPX routing.

- The MAXcess family offers three alternative methods
for operating and managing the system:
- ASCII terminal
- RADview Network Management System over PC or HPOV
- RADview Network Management System is a
Windows-based or HPOV-based SNMP application, which permits configuration,
diagnostics and monitoring from a central management station. It features
pull-down menus, dialog boxes and color graphics to guide the operator in
the execution of selected tasks. Communication with the MAXcess SNMP agent
is via a serial SLIP port, or in-band via a Frame Relay port.
- Terminal interface allows configuration, control
and error monitoring from an ASCII terminal.
- Telnet is supported allowing configuration and
control of the products over WAN or LAN.
- MAXcess incorporates numerous test features for
easy maintenance and rapid fault detection. Upon power-up and during
normal operation, automatic self-test and link-test are performed, and all
problems are reported to the management system. Alarm information is
collected and stored in memory for easy access by the management system.
- MAXcess uses FLASH memory to enable software
upgrading. A central location can be used for upgrading all remote sites.
- System modules include:
- CL - Common Logic module
- PS - Power Supply module
- Ringer - Ringer-3000R for MAXcess-3000 or RI
option for MAXcess-3004, support ringing voltage for connected
telephones, via FXS modules.
Note: Power supply redundancy can be
achieved by adding a power supply module to the Basic Unit, only in
- Up to 12 modules can be placed in the MAXcess-3000,
and five in the MAXcess-3004. Any combination of I/O modules (voice or
data) can be configured in the hub. Both MAXcess-3000 and MAXcess-3004
utilize the same voice or data I/O modules. Each data port of the low/high
speed modules can function as a network link integrating voice and data,
or as a data I/O port connected to a data device.
