SDH/SONET networks

FCD-155E is an STM-1/OC-3 add/drop
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-155E utilizes the SDH/SONET
infrastructure for cost-effective
connectivity.

Optional PDH interface modules include:•

8- or 21-port E1•

8- or 28-port T1•Single-port E3/T3•

Single-port E3 with 21-port E1•

Single-port T3 with 21-port E1 or28-port T1.

STM-1/OC-3 Add/Drop Multiplexer

Optional Ethernet interface configurations
include:•External E1•

Station clock.

•2-port bridging 10/100BaseT•

6-port 10/100BaseT (two bridging andfour transparent ports)

FCD-155E features an optional ADM
configuration mechanism with SNCP path
protection.

An optional Gigabit Ethernet port connects
one LAN port to eight virtual groups. This
option provides LAN extension overSDH/SONET networks with bridgefunctionality. The maximum frame lengthis 2 kB.

•Single-port Ethernet
10/100/1000BaseT (RJ-45) or
1000BaseSX (SFP interface).

Optional 1+1 link protection mechanism(unidirectional MSP/APS) and SNCP path
protection are also available.

Ethernet traffic is mapped into
SDH/SONET containers using VCAT andencapsulated with:

Maintenance capabilities includeuser-activated local loopbacks and remoteloopbacks on the STM-1/OC-3 main link
and PDH tributaries.

•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.

NETWORK INTERFACEThe STM-1/OC-3 interfaces areuser-configurable and provide a highquality and high-availability link, as well as
performance monitoring of the trafficpath.
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 will
ensure that prior to shipping, RAD has
performed comprehensive functional
quality tests on the entire assembled unit,
including the SFP devices. RAD cannot
guarantee full compliance to productspecifications for units using non-RADSFPs.
The user can define the following
SDH/SONET clock sources:•Internal•

Recovered from the STM-1/OC-3interface, including automatic selection
based on SSM (Synchronization StatusMessaging)

LAN INTERFACEThe 2-port 10/100BaseT or single-port
Gigabit Ethernet interfaces include abuilt-in Ethernet bridge that supports
VLAN according to IEEE 802.1Q and802.1p.
The 4-port transparent LAN extension,
without bridge functionality, creates total
separation between customers, forsecurity. The maximum frame length is2 kB.
The 10/100BaseT LAN interface featuresautonegotiation for plug-and-play
Ethernet connectivity and complies toIEEE 802.3/Ethernet V.2 standards. Theinterface also features VLAN stacking.

Figure 1. Corporate Ring Application

Each user’s Ethernet traffic can bemapped into SDH/SONET virtual containers
in any of the following ways:•

Up to 63 × VC-12, or 84 × VT-1.5•

3 × VC-3/STS-1•

1 × VC-4.

Ethernet traffic can be switched todifferent bundles of virtually concatenatedVCs (up to 8 bundles) according to apredefined group.
Link Capacity Adjustment Scheme (LCAS) is
supported in compliance with the G.7042
standard, which allocates bandwidth
according to Ethernet traffic.

Data Sheet

SDH/SONET media can transport basic
Ethernet packets of up to 1536 bytes
enabling connection to MPLS networks.

MANAGEMENTThe Spanning Tree Protocol (STP) andRapid Spanning Tree Protocol (RSTP)
support Layer 2 ring applications.

•Via DCC using IP tunneling over OSI
DCN based on ITU-T G.7712•

Via a dedicated virtual groupcontaining at least one VC-12/VT-1.5
channelTDM INTERFACES
FCD-155E has an optional interface
module consisting of 8 or 21 balanced E1or 8 or 28 T1 ports that transfer
transparent data in compliance withG.703. The unbalanced E1 interface issoftware-selectable.
An optional E3/T3 interface module
transports unframed E3/T3 data over
SDH/SONET.
Another optional interface module
combines E3 or T3 with 21 E1 ports, or T3
with 28 T1 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.

TFTP applications to update softwareand upload/download remoteconfigurations•Web Based element manager.

Remote units can be managed in thefollowing ways:•Inside the user traffic in a virtualgroup, separated from the user traffic
by the GFP Channel ID or VLAN tag•

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

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 platformor LAN port•

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

Figure 2. VPN over SDH/SONETDIAGNOSTICS
FCD-155E has comprehensive diagnostic
capabilities, including:•Ethernet and SDH/SONET linkmonitoring•

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

GENERAL
AC or DC power supplies are provided withan alarm-activated fan for forced-aircooling. They are available in redundantand mixed AC/DC power supply
configurations.
FCD-155E is a compact 1U high 19-inchunit that can be mounted in a 19-inch rackwith the optional rack-mount kit (seeOrdering).
