- MAXcess-30 integrates
data, voice, fax and LAN traffic over leased lines,
ISDN or Frame Relay networks. It supports three data
channels and two analog voice/fax or one ISDN-S0
voice channels. LAN interconnectivity is provided
via an external bridge or router, or an integral
router.
- MAXcess-30 also
operates as a compact multiprotocol FRAD, providing
voice and data access to public or private Frame
Relay networks. The FRAD capability is enhanced by
an integrated CSU/DSU, which enables connection
through a DDS network.
- Typical applications
for the MAXcess-30 include:
- Point-to-point
inter-office communication over leased lines,
Frame Relay or ISDN
- Star configuration
applications opposite a MAXcess-3000 hub at the
central site
- FRAD applications
for multiprotocol access to public or private
Frame Relay networks.
- MAXcess-30 network
link interfaces are: V.35, V.24, V.36, RS-530 or
X.21, with data rates up to 2 Mbps. In addition,
either G.703 64/128 kbps, DDS-CSU/DSU, or basic rate
ISDN "S" or "U" interface are
supported.
- There are two data
channels: one is V.24/RS-232 data channel, which
supports data rates up to 128 kbps sync and 115.2
kbps async. The other data channel is V.24/RS-232,
V.35, V.36, RS-530, which supports up to 2 Mbps, or
Ethernet interface (10BaseT). See Ordering.
- Protocols supported
are Frame Relay, FR+, HDLC, transparent or async,
IP, IPX. Other protocols such as SDLC and X.25 can
be encapsulated over Frame Relay.
- The solid firewall
security feature protects an office LAN from
undesired entry from the Internet. The single IP
address translation feature allows a small or medium
office LAN to connect to the Internet, using a
single dynamically allocated IP address from the
central access router. Connection on Demand (COD)
allows the LAN to be connected to, or disconnected
from the Internet, over ISDN, according to timeout,
traffic or management.
- High quality voice
compression at rates of 5.1, 6.4, 8.3 kbps, as well
as silence suppression, facilitate maximum
utilization of the bandwidth. In addition, priority
mechanisms coupled with segmentation of long data
frames ensure high quality voice transmission over
leased lines or Frame Relay networks.
- Voice channel
interfaces are:
- FXS - direct
telephone connection
- FXO - PABX
extension line
- E&M - PABX tie
line (FXS supports DC feed and ringer voltage)
- ISDN-S0 PBX or a
telephone extention.
- The FAX support
includes automatic fall-back to lower rates, in case
of poor line quality.
- The network link can
automatically detect and synchronize to the incoming
clock rate, while the I/O data channels support most
applications by enabling two clock modes: DCE or DTE.
- An integrated CSU/DSU
unit is available as an option and supports data
rates and services offered by the AT&T standard
Digital Data Services (DDS). The CSU/DSU interface
connects the user directly to a Standard DDS service
that supports link data rates of 56 kbps. The DDS
link is clocked from the recovered clock (loopback
timing). Transmission range for the DDS link is up
to 10.5 km (6.5 miles).
- The RADview-PC SNMP
Windows-based application provides a user friendly
GUI that facilitates setup and monitoring of any
MAXcess network whether a small point-to-point
application or a large corporate network. Remote
management is provided by a dedicated DLCI, or via
Telnet or modems on the control port.
- Setup, control and
monitoring can be performed locally, using the front
panel LCD, an ASCII terminal or the RADView-PC
application.
- MAXcess-30 is a
compact desktop unit. A rack mount kit is provided
for 19" rack installation.
