FCD-E1E
Managed E1 and Fractional E1 Access Device• E1 main link and sublink supporting both framed and unframed signals

TDM multiplexer
enables Ethernet,• One data port with selectable sync data rates of n × 64 kbps
• Optional sub-E1 drop-and-insert port
• Optional Ethernet 10/100BaseT bridge (with or without VLAN support)• Inband management with SNMP agent

Sub-E1 and Serial
Services over E1

FCD-E1E is a managed access unit thatconverts rates and interfaces for E1 andfractional E1 services.
FCD-E1E features a serial n × 64 kbps data
user interface, and/or an Ethernet LANinterface to allow LAN-to-LAN connectivity
over TDM media.

The E1 interface is compatible withvirtually all carrier-provided E1 services
and meets ITU recommendations G.703,G.704, G.706, G.732, G.823, and G.826.

The unit interconnects with RAD’s modular
DXC (DACS) products and E1 equipmentfrom other vendors, to support multilink
star applications such as access to SDH
networks, FCD, and Megaplex units.

FCD-E1E
Managed E1 and Fractional E1 Access Device

FCD-E1E supports both 2 and 16 frames
per multiframe, with or without CRC-4.
The E1 interface also accepts a 2048-kbps
data stream and converts it to an ITU-T
Rec. G.703 unframed signal for transport
over the E1 main link and sublink. Linecode is HDB3/AMI. The integral LTU
ensures a range of up to 2 km (1.2 miles)
and is software selectable.

The unit can be configured to assign datafrom the data port into consecutive
timeslots or the user can assign timeslots
manually.

The optional sub-E1 port can beconfigured to work without CRC-4, whilethe E1 main link is working with CRC-4.
E1 equipment not supporting CRC-4 canthus connect to an E1 network that does
work with CRC-4.

An optional 10/100BaseT Ethernet port
can be ordered for management, with orwithout bridge functionality.

Bypassing the sub-E1 port to the main linkensures uninterrupted service to thesub-E1 port and full immunity to hardware
and power failure.

Multiple clock source selection ensuresmaximum flexibility. Timing for the E1
main link and sublink may come from therecovered receive clock, an internal
oscillator, or the data port.

Note: The devices originally ordered withmanagement only functionality (/UTPM) can beupgraded to the /UTP (bridge and management)

Front-panel LEDs indicate power, alarms,and diagnostic loopback operation. Rearpanel LEDs on the E1 interfaces indicate
local and remote sync loss. Rear-panel
LEDs on the optional Ethernet port
indicate link integrity and activity.
FCD-E1E is available in two models:•Plastic enclosure (FCD-E1E)•Metal enclosure with LCD andpush-buttons on the front panel(FCD-E1E/L).

Both enclosures can be mounted alone orin pairs in a 19-inch rack using RAD’s
optional rack mount kits (see Ordering).

USER INTERFACESMANAGEMENT AND MAINTENANCE

The FCD-E1E unit features the followinguser interfaces:

Status and diagnostic information isdefined, configured, and monitored using
any of the following methods:•Serial data interfaces: V.24/RS-232,
V.35, V.36/RS-449, RS-530, X.21

•Ethernet 10/100BaseT LAN interface.

The synchronous data ports of FCD-E1Eoperate in the following clock modes:•••

DCE: FCD-E1E provides both transmit
and receive clocks to the userequipment, with optional sampling of
the incoming data with an invertedclock
DTE1: FCD-E1E provides the receiveclock, while the transmit clock isprovided by the attached user
equipment (not for X.21 and V.24)
DTE2: The remote user equipment
provides both transmit and receiveclocks (not for X.21 and V.24).

The optional bridge port is a standard
10/100BaseT half/full-duplex port
featuring autonegotiation and automaticcrossover support. Its interface supports
VLAN frames, automatic learning andaging. The bridge port transparently
connects FCD-E1E to remote LANs over E1links. It filters Ethernet frames andforwards only frames that are destined forthe WAN.

•Menu-driven management using thefront panel LCD with threepushbuttons (metal enclosure only)•ASCII terminal connected to the asynccontrol port•

Telnet (only with optional Ethernetport)•RADView element manager (only withoptional Ethernet port).

Up to 2048 time-stamped alarms can be
retrieved through the supervision terminal.
Maintenance capabilities includeuser-activated local and remote loopbacks
on the E1 main link, sublink, and data port.
The user can activate a BER test on themain link or sublink.
E1 network statistics are stored inmemory, according to IETF RFC4805.
Statistical information can be retrieved
locally through the control port.
FCD-E1E performs VLAN tagging andpriority labeling according to IEEE
802.1p&Q (enhanced QoS, supporting
strict/weighted fair queue mechanism,with 802.1p/DSCP/IP Precedence priority).
The unit performs rate limiting (egress andingress).
