Chapter 1 Getting to know your BCM50a Integrated Router 33
BCM50a Integrated Router Configuration — Basics
• Extended-reach ADSL (ER ADSL)
• SRA (Seamless Rate Adaptation)
• Autonegotiating rate adaptation
• ADSL physical connection ATM (Asynchronous Transfer Mode) AAL5
(Adaptation Layer type 5)·
• Multiprotocol over AAL5 (Request For Comments (RFC) 2684/1483)
• Support Point-to-Point-Protocol over ATM AAL5 (PPPoA) (RFC 2364)
• PPP over Ethernet support for DSL (Digital Subscriber Line) connection
(RFC 2516)
• Support Virtual Circuit (VC) based and LLC (Logical Link Control) based
multiplexing
• Support OAM (Operational, Administration and Maintenance) VC Hunt
• I.610 F4/F5 OAM
Networking compatibility
Your BCM50a Integrated Router is compatible with the major ADSL Digital
Subscriber Line Access Multiplexer (DSLAM) providers, making configuration
as simple as possible.
Multiplexing
The BCM50a Integrated Router supports VC-based and LLC-based multiplexing.
Encapsulation
The BCM50a Integrated Router supports PPPoA (RFC 2364 - PPP over ATM
Adaptation Layer 5), RFC 1483 encapsulation over ATM, MAC (Media Access
Control) encapsulated routing (ENET encapsulation) as well as PPP over Ethernet
(RFC 2516).
Four-Port switch
A combination of switch and router makes your BCM50a Integrated Router a
cost-effective and viable network solution. You can connect up to four computers
or phones to the BCM50a Integrated Router without the cost of a switch. Use a
switch to add more than four computers or phones to your LAN.
