FEATURES

• Integrating data, voice, fax and LAN traffic, MAXcess-300 supports six data channels and four voice/fax or one ISDN-S0 channels over Frame Relay or leased line networks. LAN interconnectivity is provided via an external bridge or router.

• MAXcess-300 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 to the Frame Relay line through the DDS network.

• Typical applications for MAXcess-300 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-300 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" interfaces are supported.

• A second network link, which can also be used as a high speed data channel of up to 2 Mbps, supports V.24, V.35, V.36 or X.21 interfaces.

• Four data channels are available. Three of the data channels support V.24/RS-232 up to 128 kbps, while the fourth channel can be V.24/RS-232, V.35, X.21, V.36/RS-530 up to 2 Mbps, or Ethernet interface (10BaseT). See Ordering.

• Protocols supported are Frame Relay, Frame Relay+, HDLC, transparent, async or 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 against 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 or statistically 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 timers, traffic or management.

• High quality voice compression at rates of 5.1, 6.4 or 8.3 kbps, together with silence suppression, ensure maximum utilization of the bandwidth. In addition, priority mechanisms together with segmentation of long data frames, enable high quality voice transmission over leased lines or Frame Relay networks.

• Voice channel interfaces include:
  • FXS - direct telephone
  • FXO - PABX extension line
  • E&M - PABX tie line
    (FXS supports DC feed and ringer voltage)

• The fax support includes automatic fall-back to lower rates, in case of poor line quality.

• The network main links automatically detect and synchronize to the incoming clock rate, while the I/O data channels support most applications by enabling three clock modes: DCE, external 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 at a data rate 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 connected to the control port.

• Setup, control and monitoring can be performed locally using the front panel LCD, an ASCII terminal or the Windows based RADView-PC station.

• MAXcess-300 is a compact 19" (1U) high unit, suitable for desktop or rack installation.
