Fig 0-2 PPPoE application in IPAM-1600s with Ethernet-All-The-Way Network
In addition to traditional ATM-based ADSL network. As Fig 0-2 displays, the
user application information is still encapsulated by ADSL CPE into ATM cells in
pre-defined VC (Virtual Channel, PVC), and then upstream the ATM cells to
DSLAM via ADSL link.
In the IPAM-1600s, all the ATM cells belong to the specified VC are
decapsulated back to the original PPPoE encapsulated Ethernet packet (if
VLAN-mode of the specified ADSL port is disabled), or mapped to the
pre-defined Ethernet-VLAN packets (if VLAN-mode of the specified ADSL port is
enabled). IPAM-1600s concentrates all Ethernet-with/without VLAN-tag packets
from 16 ports’ ADSL and uplinks to ISP’s Ethernet-All-The-Way network. The
PPPoE frames will be resolved at Broadband Access Server (BAS), and the
user application information was serviced.
The IPAM-1600s supports ADSL CPE Bridge-mode (RFC-1483 Bridge
mode) only
. For performance concern, IPAM-1600s will not act as BRAS to
process user application information directly.
IPAM-1600s provides Ethernet-with/without VLAN tag to ATM-PVC mapping
feature for the ISP to isolate user’s data with security and to provide lots of
service enhancement capabilities. IPAM-1600s supports 2 ATM PVC links for
each ADSL CPE.
