56.8 PPPoA to PPPoE (PAE) Translation
Before migrating to an Ethernet infrastructure, a broadband network might consist of PPPoA
connections between the CPE devices and the DSLAM and PPPoE connections from the
DSLAM to the BRAS (Broadband Remote Access Server). The following figure shows a
network example.
Figure 288 Mixed PPPoA-to-PPPoE Broadband Network Example
In order to allow communication between the end points (the CPE devices and the BRAS),
you need to configure the DSLAM (the IES-1248) to translate PPPoA frames to PPPoE
packets and vise versa.
When PPPoA packets are received from the CPE, the ATM headers are removed and the IES-
1248 adds PPPoE and Ethernet headers before sending the packets to the BRAS. When the
IES-1248 receives PPPoE packets from the BRAS, PPPoE and Ethernet headers are stripped
and necessary PVC information (such as encapsulation type) is added before forwarding to the
designated CPE.
You can use these commands to create PVCs for PAE translation.
