FCD-E1E
Managed E1 and Fractional E1 Access Unit
The FCD-E1E is a multiplexer and rate and
interface converter for point-to-point extension
of serial data, Ethernet and E1 services or
fractional E1 over SDH/SONET networks.
Offering a wide range of serial interfaces (V.35,
V.36, RS-530, X.21) with selectable sync data
rates of n x 64 kpbs, data port rates are
selectable for any multiple of 64 kbps up to
1,984 kbps. Unframed E1 can be supported up
to 2.048 Mbps.
The integral LTU ensures a range of up to 2 km
(1.2 miles) and is software selectable.
The unit can be programmed to assign data
automatically from the data port into
consecutive timeslots or the user can assign
timeslots manually.
Multiple clock source selection
Multiple clock source selection ensures
maximum flexibility. Timing for the E1 main link
and sublink may come from the recovered
receive clock, an internal oscillator or the data
port.
The unit interconnects with RAD's modular DXC
products and E1 equipment from other vendors,
to support multilink star applications, such as
access to SDH networks, FCD and Megaplex
units.
Ethernet extension
The FCD-E1E’s Ethernet interface allows LAN-to-
LAN connectivity over TDM.
The product’s 10/100BaseT interface supports
VLAN frames, auto-negotiation and automatic
learning and aging. It transparently connects
FCD-E1E to remote LANs over E1 links. It filters
Ethernet frames and forwards only frames that
are destined for the WAN.
FCD-E1E supports VLAN tagging and priority
labeling according to 802.1p&q. Enhanced QoS
supports strict/weighted fair queue mechanism,
with 802.1p/DSCP/IP Precedence priority.
Standards compliant
The E1 interface is compatible with carrier-
provided E1 services. The product complies with
ITU recommendations G.703, G.704, G.706,
G.732, G.823, and G.826.
Management
The FCE-E1E features an LCD front panel for
menu-driven management using three
pushbuttons.
Front panel LEDs indicate power, alarms and
diagnostic loopback operation. Rear panel LEDs
on the E1 interfaces indicate local and remote
sync loss.
Status and diagnostic information is defined,
configured, and monitored using any of the
following methods:
• Menu-driven management using the front panel
LCD with three pushbuttons
• ASCII terminal connected to the async control
port
• Telnet
• RADView element manager
FCD-E1E is a compact standalone unit. A rack
mount adapter kit enables installation of one or
two (side-by-side) units in a 19-inch rack.
