Rate adaptation support
IEEE 802.1p Priority
Your ADSL line card uses IEEE 802.1p Priority to assign priority levels to individual ports.
Multiple PVC and ATM QoS
The ADSL line card allows you to use different channels (also called Permanent Virtual Circuits or PVCs) for
different services or subscribers. Define channels
2
on each DSL port for different services or levels of service and
assign each channel a priority. ATM Quality of Service (QoS) allows you to regulate the average rate and
fluctuations of data transmission. This helps eliminate congestion to allow the transmission of real time data (such
as audio and video).
IEEE 802.1x Port-based Authentication
The ADSL line card supports the IEEE 802.1x standard for centralized user authentication and accounting
management through an optional network authentication (RADIUS) server.
Protocol
Multiple Protocols over AAL5 (RFC 1483)
Management
• Remote configuration backup/restore and firmware upgrade
• SNMP manageable
• Text-based management locally via console port and remotely via telnet
• Web configurator
MAC (Media Access Control) Filter
Use the MAC filter to filter incoming frames based on MAC (Media Access Control) address(es) that you specify.
You may enable/disable the MAC filter on specific ports. You may specify up to ten MAC addresses per port.
MAC (Media Access Control) Count Filter
You can limit the number of MAC addresses that may be dynamically learned on a port. You may enable/disable
the MAC count filter on individual ports.
System Monitoring
1
At the time of writing, the ALC1224 only supports the line rates for ADSL2 and ADSL2+ (not other features); and the
ALC1224’s interoperability when using ADSL2 and ADSL2+ has not yet been tested.
2
Up to eight channels on each DSL port at the time of writing.
