Chapter 5 Quick Setup
The Quick Setup allows the user to configure the A/VDSL router for DSL connectivity
and Internet access. It also guides the user though the WAN network setup first
and then the LAN interface setup. You can either manually customize the router or
follow the online instruction to set up the router.
The CT-5372E A/VDSL router supports the following five network operating modes
over an ATM PVC WAN interface.
PPP over Ethernet (PPPoE)
PPP over ATM (PPPoA)
MAC Encapsulated Routing (MER)
IP over ATM (IPoA)
Bridging
The following configuration considerations apply:
The WAN network operating mode operation depends on the service provider’s
configuration on the Central Office side and Broadband Access Server for the
PVC
If the service provider provides PPPoE service, then the connection selection
depends on whether the LAN-side device (typically a PC) is running a PPPoE
client or whether the CT-5372E is to run the PPPoE client. The CT-5372E can
support both cases simultaneously.
If some or none of the LAN-side devices do not run PPPoE client, then select
PPPoE. If every LAN-side device is running a PPPoE client, then select Bridge
in PPPoE mode. CT-5372E also supports pass-through PPPoE sessions from the
LAN side while simultaneously running a PPPoE client for non-PPPoE LAN
devices.
NAPT and firewall are always enabled when PPPoE mode is selected, but they
can be enabled or disabled by the user when MER or IPoA is selected, NAPT and
firewall are always disabled when Bridge mode is selected.
Depending on the network operating mode, and whether NAPT and firewall are
enabled or disabled, the main panel will display or hide the NAPT/Firewall
menu. For instance, at initial setup, the default network operating mode is
Bridge. The main panel will not show the NAPT and Firewall menu.
