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.
Configuration procedure
To configure a CE1/PRI interface:
1. Select Interface Setup > WAN Interface Setup from the navigation tree.
2. Click the icon for the CE1/PRI interface.
3. Configure the CE1/PRI interface, as described in "Configuring a CE1/PRI interface in E1 mode"
and "Configuring a CE1/PRI interface in CE1 mode."
