4.2.2 ATM Interface
A network service defines the data encapsulation and protocol characteristics
for the connection between two packet switching devices. The CT-510
supports PPP, PPPOE, Routed RFC1483 and Bridged RFC1483. The CT-510 and
the remote ISP should use the same network service to establish the session.
For PPP and PPPOE network services, the device supports two authentication
protocols: PAP and CHAP. These two services can identify the server’s
authentication protocol and will auto-adjust to the same protocol.
Follow the steps below to set the ATM interface. There are 16 ATM interfaces.
The default values of these interfaces are ATM1 to ATM10 enabled with the
others disabled.
Step 1 Enter the MAIN/QC/ATM menu.
Step 2 Enter an ATM interface leaf menu, ATM1 to ATM16, e.g.,
MAIN/QC/ATM/ATM1.
Step 3 Enter a parameter in each field.
Interface: Enable or disable the ATM interface
Protocol
1. Ethernet (Bridged RFC1483): This is the factory default.
2. IP Over ATM: Routed RFC1483
3. PPP (PPP over ATM):
a. Configure the IPCP and ISP fields.
b. Enter the corresponding ATM VC leaf menu and select
VCMUX from the AAL5 encapsulation field (also mentioned
in Section 4.2.3).
4. PPPOE (PPP over Ethernet):
a. Configure the IPCP and ISP fields.
b. Enter the corresponding ATM VC leaf menu and select
LLC
from the AAL5 encapsulation field (also mentioned in
Section 4.2.3) or refer to the setting of the remote terminal.
IPCP (For PPP/PPPOE):
Static – A local IP address is assigned manually during the PPP
session establishment.
Dynamic – A local IP address is obtained dynamically from the
remote PPP server during the PPP session establishment.
PPP Keep Alive Interval : the default is 10 seconds
ISP (For PPP/PPPOE): Assign this ATM interface to one of the
eight ISPs and then enter the selected ISP menu to assign the
required authentication user name and password for PAP and
CHAP. For example, if you have selected ISP1 in this field.
Enter the
MAIN/QC/ISP/ISP1 menu to configure the ISP1
parameters. Refer to Section 4.2.4 for more details.
