FCD-IP
E1/T1 or Fractional E1/T1 Access Unit
with Integrated Router
The FCD-IP is an access unit for full or fractional 
E1/T1 services with an integrated router. It can 
be ordered with one or two independent 
Ethernet LAN ports or alternatively with an 
integrated four-port switch that can replace an 
external hub or switch. An optional data port, 
sub-E1/T1 drop-and-insert port or four analog 
ports (FXS, FXO, E&M) are also available. The 
data port rates are selectable for any multiple of 
56 kbps or 64 kbps, up to 1,984 kbps.
The FCD-IP is available with a software 
selectable internal LTU, and allows direct 
connection to the E1 network or connection via 
an external LTU. A built-in CSU/DSU allows direct 
connection to a T1 network.
Integrated router 
The integrated router supports:
• IP/IPX routing and transparent bridging
• Backup router link capability
• Quick setup and configuration
• Solid Firewall™ (session-based) protection
• NAT and Single IP address translation
• PAP/CHAP security
• OSPF, RIP-1, RIP-2 
The FCD-IP can also be used as an integrating 
multiplexer for LAN, data and fractional E1/T1 
services.
The FCD-IP operates with RAD’s modular DXC 
multiservice access node products for multilink 
star applications, including access to SDH 
networks. The DXC and FCD-IP units operate 
under centralized SNMP network management.
Timeslot assignment is programmable, allowing 
data from the LAN, sub-E1/T1, analog voice, and 
data ports to be placed into timeslots, either 
consecutively or alternately. The FCD-IP also 
allows flexible allocation of the data port 
timeslots. Each timeslot of the sub-E1/T1 port is 
placed on the same timeslot of the main E1/T1 
link. 
Ring and drop-and-insert capabilities
FCD-IP provides up to four fractional E1 links 
with automatic bypass in case of link failure. 
This unit can be deployed in ring and 
daisy-chain applications together with the 
Megaplex multiplexers, to affordably connect 
smaller sites to the E1 ring, while offering the 
same self-healing link protection capabilities as 
the larger devices.
The E1 unit meets all requirements of ITU 
recommendations G.703, G.704, G.706 and 
G.732. 
The T1 interface is compatible with virtually all 
carrier-provided T1 services.
Management and maintenance 
Setup, control and monitoring of status and 
diagnostic information can be done using:
•
  ASCII terminal connected to control port
•
  Telnet
•
  SNMP management
•
  Inband management via dedicated timeslot
The FCD-IP supports an internal SNMP agent 
and can be controlled by any generic SNMP 
station or by the RADview SNMP network 
management application.
The FCD-IP supports dial-in, which can be used 
for remote out-of-band configuration and 
monitoring.
Maintenance capabilities include user-activated 
local and remote loopbacks.
The FCD-IP is available as a standalone unit for 
the desktop or a 19-inch rack shelf.
