FCD-155E
STM-1/OC-3 Add-Drop Multiplexer
STM-1/OC-3 add/drop
• STM-1/OC-3 PDH/Ethernet add/drop multiplexer for grooming LAN and legacy
(TDM) traffic over SDH/SONET networks
multiplexer that
• Ethernet traffic mapped to 1 VC-3/VC-4/STS-1, up to 3 VC-3/STS-1, up to 63
VC-12 or 84 VT-1.5
transports LAN and
traditional (TDM)
traffic over
SDH/SONET networks
• 1+1 MSP/APS redundancy
• PDH interface for 8 or 21 E1 (G.703), 8 or 28 T1 (G.703), 1 E3/T3, or 1 E3/T3
with 21/28 E1/T1 ports
• 10/100BaseT and GbE Ethernet interfaces with VLAN support and
point-to-multipoint switching capability
FCD-155E is an STM-1/OC-3 add/drop
multiplexer that transports LAN and
traditional (TDM) traffic over SDH/SONET
networks. When bandwidth granularity of
the Ethernet channel is configured to
2 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 or
28-port T1
FCD-155E
STM-1/OC-3 Add-Drop Multiplexer
•
External E1
•
Station clock.
•
2-port bridging 10/100BaseT
•
6-port 10/100BaseT (two bridging and
four 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 over
SDH/SONET networks with bridge
functionality. The maximum frame length
is 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 and
encapsulated with:
Maintenance capabilities include
user-activated local loopbacks and remote
loopbacks on the STM-1/OC-3 main link
and PDH tributaries.
•
Generic Framing Procedure (ITU-T
G.7041, ANSI T1-105.02), framed
mode
•
Link Access Procedure for SDH/SONET
(LAPS) protocols following draft
recommendation ITU-T X.85/X.86.
Optional Ethernet interface configurations
include:
NETWORK INTERFACE
The STM-1/OC-3 interfaces are
user-configurable and provide a highquality and high-availability link, as well as
performance monitoring of the traffic
path.
The STM-1/OC-3 link is supplied with an
SFP socket (see Ordering). It is strongly
recommended to order this device with
original 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 product
specifications for units using non-RAD
SFPs.
The user can define the following
SDH/SONET clock sources:
•
Internal
•
Recovered from the STM-1/OC-3
interface, including automatic selection
based on SSM (Synchronization Status
Messaging)
LAN INTERFACE
The 2-port 10/100BaseT or single-port
Gigabit Ethernet interfaces include a
built-in Ethernet bridge that supports
VLAN according to IEEE 802.1Q and
802.1p.
The 4-port transparent LAN extension,
without bridge functionality, creates total
separation between customers, for
security. The maximum frame length is
2 kB.
The 10/100BaseT LAN interface features
autonegotiation for plug-and-play
Ethernet connectivity and complies to
IEEE 802.3/Ethernet V.2 standards. The
interface also features VLAN stacking.

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

MANAGEMENT
The Spanning Tree Protocol (STP) and
Rapid Spanning Tree Protocol (RSTP)
support Layer 2 ring applications.
•
Via DCC using IP tunneling over OSI
DCN based on ITU-T G.7712
•
Via DCC based on IP/PPP protocols
•
Via a dedicated virtual group
containing at least one VC-12/VT-1.5
channel
TDM INTERFACES
FCD-155E has an optional interface
module consisting of 8 or 21 balanced E1
or 8 or 28 T1 ports that transfer
transparent data in compliance with
G.703. The unbalanced E1 interface is
software-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 software
and upload/download remote
configurations
•
Web Based element manager.
Remote units can be managed in the
following ways:
•
Inside the user traffic in a virtual
group, separated from the user traffic
by the GFP Channel ID or VLAN tag
•
Out-of-band, via direct connection to
one of the LAN ports.
Status and diagnostic information is
defined, configured, and monitored using
one of the following methods:
•
ASCII terminal connected to the
V.24/RS-232 control port
•
Telnet host via management platform
or LAN port
•
Network management station running
RADview, the RAD SNMP network
management application
DIAGNOSTICS
FCD-155E has comprehensive diagnostic
capabilities, including:
•
Ethernet and SDH/SONET link
monitoring
•
Real-time alarms to alert the user of
fault conditions. Alarms are reported
to the management station and
simultaneously relayed through a dry
contact port.
GENERAL
AC or DC power supplies are provided with
an alarm-activated fan for forced-air
cooling. They are available in redundant
and mixed AC/DC power supply
configurations.
FCD-155E is a compact 1U high 19-inch
unit that can be mounted in a 19-inch rack
with the optional rack-mount kit (see
Ordering).
