1-8 Overview
ACE-3105, ACE-3205 Ver. 5.2
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. For
detailed information about the ATM OAM functionality, refer to
Appendix C
.
Performance Monitoring
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-3105, ACE-3205 collects statistics per physical port and per connection for
15-minute intervals. Statistics for the last 6 hours are stored in the device and
can be retrieved at the network management station.
ACE-3105, ACE-3205 maintains a cyclic event log file that stores up to 2000
time-stamped events. In addition, an internal system log agent can send all
reported events to a centralized repository or remote server.
Management and Security
ACE-3105, ACE-3205 can be managed using different access methods, via:
•
The dedicated RS-232 or 100BaseT ports (out-of-band, when the port is not
used for Ethernet traffic or clock recovery)
•
Ethernet uplink port, using IP-based connection (raw IP or over PW).
The unit can be fully managed and controlled using the following:
•
Menu-driven terminal utility – management via a local ASCII-based terminal
connection or a Telnet/SSH (Secure Shell Client) connection, accessible via an
IP-based connection. Instead of sending plain-text ASCII-based commands
and login requests over the network, SSH provides a secure communication
channel
•
ConfiguRAD – Web-based/SSL based element management utility, embedded
in ACE-3105, ACE-3205 for IP-based, installation-free access to the unit from
any computer equipped with a standard Web browser. If enabled, the SSL
protocol encrypts the data between the TCP and HTTP Web layers.
•
RADview-EMS – RAD’s CORBA-based element management system, providing
a dedicated PC/Unix-based GUI for controlling and monitoring the unit from a
network management station. It also includes northbound CORBA interface
for integration into any third-party NMS (network management system). For
additional information, refer to the RADview-EMS/NGN User's Manual.
