Data Sheet
MAIN MODULES
The main module of ACE-3600 serves as
the core processing component of the
unit, and can be replaced when necessary.
SYSTEM REDUNDANCY
ACE-3600 allows two identical main
modules to work in redundancy mode,
which protects the unit's data matrix and
main CPU in cases of unexpected module
reset. One main module is set as the
active module, while the second is in
standby mode, ready to work in place of
the active one at any moment.
OAM AND DIAGNOSTICS
Comprehensive monitoring and diagnostic
capabilities include:
• Pseudowire connectivity check
• External and internal physical loopbacks
on STM-1/OC-3c ports
• Cell test towards the ATM connections.
ACE-3600 periodically verifies the
connectivity status of pseudowire
connections, using VCCV-BFD messages
according to the 'draft-ietf-bfd-base'
requirements.
If a failure is detected, a notification is
sent to both the remote peer and the ATM
connection of the specific PW. This allows
complete monitoring over the pseudowire
connections in real-time
ATM and PSN port alarms are forwarded
over the packet-switched network from
end to end. This includes the mapping of:
• Packet-switched network alarms to
ATM alarms
• ATM alarms over the PSN to the remote
customer equipment (CE)
• Physical failures of ATM ports, over the
packet-switched network towards both
the local and remote CE.
For conventional ATM cross-connects
(XCs), OAM is supported according to
ITU I.610 requirements:
• F4 and F5 OAM
• Configurable OAM mode per connection
point
• Segment/intermediate mode for user
connections and end-to-end mode for
the management connection
• AIS and RDI cell detection and
generation upon physical layer and ATM
layer failures
• CC cell generation and LOC state
detection per VP/VC
• Loopback location ID and configurable
loopback source ID per device.
Performance monitoring is provided by
Ethernet and IP-layer network condition
statistics, such as packet sequence errors
(loss or misorder) and packet delay
variation (jitter), which are monitored and
stored by the device.
ACE-3600 collects statistics per physical
port and per VCC for 15-minute intervals.
Statistics for the last 6 hours are stored in
the device and can be retrieved at the
network management station.
For diagnostics purposes, ACE-3600
maintains a cyclic event log file that stores
up to 4096 time-stamped events.
In addition, an internal system log agent
can send all reported events to a
centralized repository or remote server.
MANAGEMENT
ACE-3600 can be managed using different
access methods, via:
• Dedicated RS-232 or 10/100BaseT
ports
