Managed interface converter

The FCD-E1L is a managed single or dual port interface converter for full or fractional E1 services. Data port rates are selectable for any multiple of 64 kbps up to 1,984 kbps. Alternatively, unframed E1 can be supported up to 2.048 Mbps.

Data or Ethernet port

The basic unit is available with a single data port and an optional second data port. The second data port can be replaced by an Ethernet bridge, 10/100 VLAN bridge or 10BaseT router to provide direct connection to the LAN.

For ease of installation, the FCD-E1L managed interface converter offers plug-and-play connectivity. Upon connection to the E1 link, the unit automatically detects the E1 parameters and autoconfigures accordingly. Manual configuration is also possible.

The FCD-E1L managed interface converter is available with an integral LTU (line termination unit) that ensures a range of up to 2 km (1.2 miles).

Meets all E1 protocol requirements

The FCD-E1L managed interface converter meets all requirements of ITU G.703, G.704, G.706, G.732 and G.823. It supports both two and 16 frames per multiframe, with or without CRC-4. Zero suppression over the line is HDB3.

The unit may be clocked from the recovered receive clock of the main/sub-E1 link or from an internal oscillator. The data channel interface is RS-530. Adapter cables are available for V.35, V.36/RS-422 or X.21.

The FCD-E1L supports an internal SNMP agent and can be managed by any generic SNMP station or by the RADview SNMP network management application. The unit supports dial-in/dial-out, which can be used for remote out-of-band configuration and monitoring (dial-in) and for alarms (dial-out).

Diagnostics include user activated local loopbacks on the main/sub-E1 link and DCE data port. A pseudo-random data pattern (BERT) can be used to check the transmission path as well as the local and remote units.

The compact, 1U-high, half-19” device is available as a desktop standalone or for mounting in a 19" rack shelf.
