• SNMP and Telnet support

• FLASH memory for software and parameter file downloading

E1 FEATURES

• Integral E1 with or without LTU

• Optional sub-E1 drop & insert port for PABX connectivity

• Fail-safe bypass for the sub-E1 link

• Optional fiber optic uplink

T1 FEATURES

• Integral T1 CSU/DSU

• Optional sub-T1 drop & insert port for PABX connectivity

• Fail-safe bypass for the sub-T1 link

• Optional fiber optic uplink

ANALOG VOICE FEATURES

• Supports four analog channels

• PCM encoded, A-Law or ?-Law

• Supports three interface options:

  • 2-wire FXS

  • 2 wire FXO

  • 4-wire or 2-wire E&M

• WEB RANger-II connects small or medium size offices to the Internet / Intranet.

• Supported WAN services are:

• T1 or fractional T1 CSU/DSU, operating at up to 1.544 Mbps

• E1 or fractional E1, with or without LTU, operating at rates up to 2.048 Mbps

• E1 or T1 over fiber optic links

• Frame Relay with auto learn of DLCI and maintenance protocol

• ISDN BRI

• DDS

• Leased lines.

• A variety of data interfaces are available, such as V.35, V.24, V.36, X.21, and ISDN BRI.

• WEB RANger-II supports IP/IPX routing and bridging.

• Internet access capabilities are enhanced through:

• IP Service Access Authentication that is provided by PAP/CHAP

• Solid Firewall that protects an office LAN from undesired entry from the Internet

• NAT that allows the sharing of several legal IP addresses between the various LAN users

• Single IP address translation that allows a small or medium office LAN to connect to the Internet, using a single dynamically or statically allocated IP address

• DHCP server that allows the sharing of IP address pools between DHCP clients on the LAN.

• The quad analog voice or sub-E1/T1 drop & insert ports provide toll-quality voice transmission.

• The fail-safe bypass of the sub-E1/T1 link ensures the continuity of voice services in case of power supply failures.

• ISDN or dial backup ensure the continuity of data services.

• Connection On Demand (COD) and Bandwidth On Demand (BOD), together with advanced filtering, reduce communication expenses of ISDN services.

• Easy configuration through a quick setup menu is performed via a terminal attached to the control port, or via Telnet access into the device over LAN or WAN. The SNMP agent provides management by RADview or any other standard SNMP management station.

• Undesired access to the WEB RANger-II via Telnet or SNMP can be blocked or password protected.

• The dual-level management authentication allows the user access to router configuration parameters, while restricting access to network configuration parameters.

• Software download is available via the control port using XMODEM, and via LAN/WAN using TFTP.

• Parameter file download and upload is available via LAN or WAN using TFTP
