FCD-E1I   E1 or Fractional E1 Access Unit

RAD FCD-IP E1/T1 or Fractional E1/T1 Access Unit with Integrated Router 

  • FCD-IP is an E1/T1 or fractional E1/T1 Integrated Access Device (IAD), which enables service providers to bundle voice and Internet access services over a single E1 or T1 access line (See Figure 1).
  • The FCD-IP is also ideal for management applications in cellular or SDH environments (See Figures 2 and 3).
  • 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 up to 2.048 Mbps
    • E1 or T1 over fiber optic links
    • Frame Relay with auto-learn of DLCI and maintenance protocol
    • ISDN BRI (U or S interface) for data services backup.
  • An integrated router supports IP/IPX routing and transparent 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 feature 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 sub-E1/T1 or quad analog voice 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.
  • An optional data port can be utilized either as a second serial router port or as a transparent nx64, nx56 data port for legacy equipment connectivity.
  • Configuration is easily accomplished through a quick setup menu using a terminal attached to the control port or by Telnet access into the device over the LAN/WAN.
  • FCD-IP features a variety of inband and out-of-band management options. These options include dedicated time slot, dedicated DLCI and dial-in connectivity.
  • The SNMP agent provides management by RADview or any other standard SNMP management station.
  • Undesired access to the FCD-IP via Telnet or SNMP can be blocked or password protected.
  • The dual-level management authentication allows the user an access to router configuration parameters, while restricting the user 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.
