FCD-155
STM-1/OC-3 Terminal Multiplexer

Transports LAN and• Groomed LAN and legacy (TDM) traffic over SDH/SONET networks• VLAN and point-to-multipoint switching

TDM traffic over

• Ethernet traffic mapped to one VC-3/VC-4/STS-1, up to 3 VC-3/STS-1, up to 63
VC-12 or 84 VT-1.5

SDH/SONET networks• 4 or 8 × E1/T1 (G.703) or a single E3/T3 link on the PDH interface• Channelized STM-1/OC-3 main link with fiber interface

FCD-155 is an STM-1/OC-3 SDH terminal
multiplexer that transports LAN andtraditional (TDM) traffic over SDH/SONET
networks. When bandwidth granularity of
the Ethernet channel is configured to2 Mbps (VC-12) or 1.5 Mbps (VT-1.5),
FCD-155 utilizes the SDH/SONET
infrastructure for cost-effective
connectivity.
Optional PDH interfaces include:•4- or 8-port E1 or T1 interfaces•

Single-port E3/T3 interface.

Optional Ethernet interface configurations
include:•2-port bridging 10/100BaseT interface•

6-port 10/100BaseT interface (twobridging and four transparent ports)•

Single-port Ethernet interface with
2-port bridging 10/100BaseT and
10/100/1000BaseT (RJ-45) or
1000BaseSX (SFP interface).

NETWORK INTERFACELAN INTERFACEThe STM-1/OC-3 interfaces areuser-configurable and provide ahigh-quality and high-availability link aswell as performance monitoring of thetraffic path.

The 2-port 10/100BaseT or single-port
Gigabit Ethernet interfaces include abuilt-in Ethernet bridge that supports
VLAN according to IEEE 802.1Q and
802.1p.

The STM-1/OC-3 link is supplied with an
SFP socket (see Ordering). It is strongly
recommended to order this device withoriginal RAD SFPs installed. This ensuresthat prior to shipping, RAD has performed
comprehensive functional quality tests on
the entire assembled unit, including theSFP devices. RAD cannot guarantee fullcompliance to product specifications forunits using non-RAD SFPs.

The 4-port transparent LAN extension,
without bridge functionality, creates total
separation between customers, forsecurity. The maximum frame length is
2 kb.

The user can define the following
SDH/SONET clock sources:

An optional Gigabit Ethernet port connectsof one LAN port to eight virtual groups.
This option extends LAN over SDH/SONET
networks with bridge functionality. Themaximum frame length is 2 kb.

The 10/100BaseT LAN interface featuresautonegotiation for plug-and-play
Ethernet connectivity and complies toIEEE 802.3/Ethernet V.2 standards. Theinterface also performs VLAN stacking.

•Internal•

Recovered from the STM-1/OC-3
interface, including automatic selection
based on SSM (Synchronization Status
Messaging)•External E1.

FCD-155 features an optional 1+1 linkprotection mechanism (unidirectionalMSP/APS) and SNCP path protection.
Maintenance capabilities includeuser-activated local loopbacks and remoteloopbacks on the STM-1/OC-3 main link
and PDH tributaries.

Ethernet traffic is mapped intoSDH/SONET containers using VCAT andencapsulated with:•Generic Framing Procedure (ITU-TG.7041, ANSI T1-105.02), framedmode•

Link Access Procedure for SDH/SONET(LAPS) protocols following draft
recommendation ITU-T X.85/X.86.

Each user’s Ethernet traffic can bemapped into SDH/SONET virtual containers
in any of the following ways:•Up to 63 x VC-12, or 84 x VT-1.5•3 x VC-3/STS-1•

1 x VC-4.

Ethernet traffic can be switched todifferent bundles of virtually concatenated
VCs (up to 8 bundles) according to apredefined group.
Link Capacity Adjustment Scheme (LCAS) is
implemented in compliance with theG.7042 standard, which allocatesbandwidth according to Ethernet traffic.
SDH/SONET media transport basic
Ethernet packets of up to 1536 bytes forconnection to MPLS networks.
The Ethernet interfaces interconnect SAN(Storage Area Networks) devices with
Ethernet packets of up to 2 kb.
Spanning Tree Protocol (STP) and Rapid
Spanning Tree Protocol (RSTP) support
Layer 2 ring applications.

TDM INTERFACEMANAGEMENTDIAGNOSTICS

FCD-155 has an optional interface module
containing 4 or 8 E1/T1 balanced interface
ports that transfer data transparently incompliance with the G.703 standard.
The unbalanced E1 interface is software
selectable on the 8-port version. The
4-port version is jumper-selectable andrequires an adapter cable (see Ordering).

Remote units can be managed in any of
the following ways:

FCD-155 has comprehensive diagnostic
capabilities, including:•DCC using IP tunneling over OSI DCN
based on ITU-T G.7712•Ethernet and SDH/SONET linkmonitoring•

IP/PPP over DCC protocol••

Dedicated virtual group containing atleast one VC-12/VT-1.5 channel

An optional E3/T3 port transports
unframed E3/T3 links over SDH/SONET.

•Inside user traffic in a virtual groupseparated by the GFP Channel ID orVLAN tag

Real-time alarms that alert the user offault conditions. Alarms are reported
to the management station andsimultaneously relayed through a drycontact port.

•Out-of-band, via direct connection toone of the LAN ports.

TDM traffic is mapped into SDH/SONET
VC-12/VC-11/VC-3 or SONET VT1.5/STS-1
containers that can be placed anywhere
within the STM-1/OC-3 bandwidth.

Status and diagnostic information isdefined, configured, and monitored using
one of the following methods:•ASCII terminal connected to theV.24/RS-232 control port•

Telnet host via management platform
or LAN port•

Network management station running
RADview, the RAD SNMP network
management application•

TFTP applications to update softwareand upload/download remoteconfigurations•ConfiguRAD via Web browser.

GENERAL
An AC or DC power supply is provided withan alarm-activated fan for forced-aircooling.
FCD-155 is a compact standalone unit.
One or two units can be installedside-by-side in a 19-inch rack using theoptional rack-mount adaptor kit. One
unit can be mounted on the wall using theoptional wall-mount adapter kit (seeOrdering).
