tion
Interface Status
Display and set the interface status:
• Connected—Indicating that the current interface is up and connected, click
Disable to shut down the interface.
• Not connected—Indicating that the current interface is up but not connected,
click Disable to shut down the interface.
• Administratively Down—Indicating that the current interface is shut down by a
network administrator, click Enable to bring up the interface.
Connect Mode: PPPoEoA Select PPPoEoA as the connection mode.
PVC Set the VPI/VCI value for the PVC.
User Name Configure the username for authentication.
Password
Displays whether a password is configured for authentication.
If the field displays null, no password is configured for authentication.
New Password Set or modify the password for authentication.
TCP-MSS Configure the TCP MSS on the interface.
MTU Configure the MTU on the interface.
Idle timeout
Set the idle timeout time for a connection:
• Online for all time—The connection is maintained until being disconnected
manually or upon an anomaly.
• Online according to the Idle Timeout value—The connection is disconnected
automatically if no traffic is transmitted or received on the link for a period of
time. The connection will be re-set up when an access to the Internet request is
received.
If you select Online according to the Idle Timeout value, you must set the Idle
timeout value.
Configuring a CE1/PRI interface
Overview
The CE1/PRI interface supports PPP connection mode. For details about PPP, refer to section Configuring
an SA interface.
The CE1/PRI interface can operate in either E1 mode (also called non-channelized mode) and CE1
mode (that is, channelized mode).
• A CE1/PRI interface in E1 mode equals an interface of 2048 Mbps data bandwidth, on which no
timeslots are divided. Its logical features are the same as those of a synchronous serial interface. It
supports link layer protocols such as PPP, FR, LAPB and X.25 and network protocols such as IP and
IPX.
• A CE1/PRI interface in CE1 mode is physically divided into 32 timeslots numbered 0 to 31. Among
them, timeslot 0 is used for transmitting synchronizing information. All the timeslots except timeslot
0 can be randomly divided into multiple channel sets and each set can be used as an interface
upon timeslot bundling. Its logical features are the same as those of a synchronous serial interface.
It supports link layer protocols such as PPP, HDLC, FR, LAPB and X.25, and network protocols such
as IP.
