FCD-E1, FCD-E1A

E1 or Fractional E1 Access Units

The FCD-E1 is an access unit for full or fractional

E1 services. Available with either one or two

data ports and an optional sub-E1 drop-and-

insert port, data port rates are selectable for

any multiple of 56 kbps or 64 kbps, up to

1,984 kbps. Alternatively, one of the data ports

can be replaced by an Ethernet bridge, providing

direct connection to the LAN. In the FCD-E1A,

one of the data ports can also be replaced by

four S0 interfaces for ISDN BRI extension, or by

an ISDN backup interface.

Internal or external line termination unit

The FCD-E1 is available with or without an

internal LTU (line termination unit), allowing

direct connection to the E1 network or

connection via an external LTU. In the FCD-E1A

this capability is built-in and can be configured

with or without an LTU by the customer.

Interoperability with the DXC multiservice

access node

The FCD-E1 and FCD-E1A can operate with

RAD’s modular DXC multiservice access node

products for multilink star applications, including

access to SDH networks.

Programmable timeslot allocation

Timeslot assignment is programmable, allowing

data from each data port and from the sub-E1

port to be placed into timeslots on the main

link, either consecutively or alternately.

Multiple clock source selection ensures

maximum flexibility, enabling the support of

different applications.

Immunity to hardware and power failures is

provided by bypassing the sub-E1 port to the

main E1 link, ensuring uninterrupted service to

the sub-E1 port.

Standards compliant

The FCD-E1 and FCD-E1A comply with ITU

recommendations G.703, G.704, G.706, and

G.732. It supports both two and 16 frames per

multiframe, with or without CRC-4. Zero

suppression over the line is HDB3. The integral

LTU ensures a range of up to 2 km (1.2 miles).

Setup, control and monitoring

Setup, control and monitoring of status and

diagnostic information can be activated via:

• Front panel LCD with pushbuttons (menu-

driven management)

• ASCII terminal connected to the async

control port (command line interpreter)

• SNMP management connected to the async

control port

• Inband management through a dedicated

timeslot or TS0, supporting proprietary

protocol and Frame Relay RFC 1490

Network management

The products support an internal SNMP agent

and can be controlled by any generic SNMP

station or by the RADview-EMS or

RADview-SC/TDM (FCD-E1A only) SNMP network

management application.

The units support dial-in/dial-out, which can be

used for remote out-of-band configuration and

monitoring (dial-in) and for alarms (dial-out).
