The device supports the ADSL, VDSL, and G.SHDSL interface cards (together called DSL interface cards). DSL links can be used to connect the device to the Internet.

Mode Switching

Context

The VDSL and G.SHDSL interfaces can work in ATM or PTM mode and switch between these two modes. An ADSL interface works only in ATM mode.

The VDSL and G.SHDSL interfaces support the following transfer modes:

Asynchronous Transfer Mode (ATM): ATM cells are transmitted over VDSL and G.SHDSL lines.
Packet Transfer Mode (PTM): Ethernet frames are transmitted over VDSL and G.SHDSL lines.

The device functions as a CPE and must have the same interface transfer mode as the peer device. For example, when the G.SHDSL interface of the peer device works in ATM mode, the G.SHDSL interface of the device must also work in ATM mode. The device can communicate with the peer device only when the device's G.SHDSL interface has the same transfer mode as the peer device.

2. Click Mode Switching to display the Mode Switching tab page.
3. Click Convert in the Operation column of DSL Card List.
4. Click OK.
  The configuration takes effect after several minutes.

3G/LTE Interface

Context

Although wired WAN access technologies such as access through the optical fiber, xDSL interface, or E1/T1 interface are mature and widely used, wired WAN access service may meet the bottleneck in the following scenarios:

In remote branch companies or offshore oil fields, the wired WAN access service may be unavailable or too expensive.
The wired WAN access service is restored on the disaster site only after wires are connected quickly and in a timely manner.
The wired WAN cannot cover all gas stations and ATMs that are widely distributed.
Enterprise staff require mobile office applications.

In these scenarios, wireless WAN access service is required. A 3G/LTE cellular interface is a physical interface supporting 3G/LTE technology. It provides users with an enterprise-class wireless WAN access services.

AR651C, AR611W, AR617W and AR651F-Lite do not support 3G and LTE cellular interfaces.

Only V300R019C10 and earlier versions support this interface.

Online mode	Dialup mode. When this parameter is set to Always online, the DCC immediately attempts to dial the remote end after a router starts. The dialing process is not triggered by data packets. If a connection cannot be established with the remote end, the router retries at an interval. The value Always online applies to scenarios where traffic and online duration are not charged. When this parameter is set to Disconnected after idle timeout, a link is established only when data is transmitted. When no traffic exists on the link within a specified period, the router removes the link to save traffic.

After changing the MTU of the interface, restart the interface to make the configuration take effect. The default value of MTU is 1500.
Enable NAT	NAT must be enabled when a PC on a private network connects to the Internet.
Load balancing	Two load balancing modes are supported: UCMP: Unequal Cost Multiple Path ECMP: Equal Cost Multiple Path
TCP-MSS (Byte)	MSS of TCP packets on the interface. The MSS refers to the maximum length of a TCP packet segment sent from the peer device to the local device. During TCP connection negotiation, devices at both ends record the MSS of each other. When sending TCP packets, devices at both ends limit the size of TCP packets within the MSS.

The default dialup string is #777 when the 3G/LTE/5G Interface supports CDMA2000 standard. NOTE: In V300R019C13 and earlier versions: Dial String* is mandatory. In V300R019C13 and later versions: If the Online mode is Always online, the Dial String is optional. When the Online mode is set to Disconnected after idle timeout, the Dial String is mandatory.
Online mode	Dialup mode. When this parameter is set to Always online, the DCC immediately attempts to dial the remote end after a router starts. The dialing process is not triggered by data packets. If a connection cannot be established with the remote end, the router retries at an interval. The value Always online applies to scenarios where traffic and online duration are not charged.

MTU (Byte)	MTU of an interface. If the MTU is set too small and the size of packets is oversized, packets will be divided into a great number of fragments, and be discarded by QoS queues. If the MTU is set too large, packets are transmitted at a low speed, and even some packets are lost. After changing the MTU of the interface, restart the interface to make the configuration take effect. The default value of MTU is 1500.
Enable NAT	NAT must be enabled when a PC on a private network connects to the Internet.
Load balancing	Two load balancing modes are supported: UCMP: Unequal Cost Multiple Path ECMP: Equal Cost Multiple Path
TCP-MSS (Byte)	MSS of TCP packets on the interface. The MSS refers to the maximum length of a TCP packet segment sent from the peer device to the local device.

Enable NAT	NAT must be enabled when a PC on the private network of a LAN connects to the Internet.
Load balancing	Two load balancing modes are supported: UCMP: Unequal Cost Multiple Path ECMP: Equal Cost Multiple Path
TCP-MSS (Byte)	MSS of TCP packets on an interface. The MSS refers to the maximum length of a TCP packet segment sent from the peer device to the local device. During TCP connection negotiation, devices at both ends record the MSS of each other. When sending TCP packets, the devices limit the size of TCP packets within the MSS.
VPN instance	VPN instance bound to an interface. NOTE: Before setting this parameter, you must create an IPv4 VPN instance. For the detailed procedure, see VPN Instance.

Table 1-85 Description of the Broadband dialup parameters (IPv4)

Parameter	Description
MTU (bytes)	MTU of an interface. If the MTU is set too small and the size of packets is large, packets will be broken into a great number of fragments and be discarded by QoS queues. If the MTU is too large, packets are transmitted slowly or even lost. The default value of MTU is 1500.
Enable NAT	NAT must be enabled when a PC on the private network of a LAN connects to the Internet.
User name	User name for PPPoE dial-up.
Password	Password for PPPoE dial-up.
Status	State for PPPoE dial-up.
Online mode	PPPoE dial-up mode. Always online: The DCC attempts to dial the remote end immediately after the device starts. The dialing process is not triggered by data packets. If a connection cannot be established with the remote end, the DCC retries at an interval. This mode applies to the scenarios in which users are not charged based on traffic or time. Disconnected after idle timeout: The device triggers the process of establishing a link only when there is data to be transmitted. When the time during which no traffic is transmitted on the link exceeds the timeout duration, the device disconnects the link to save traffic. This mode applies to the scenarios in which users are charged based on traffic or time. If this mode is used, the link idle time must be specified. The default link idle time is 120.
Authentication mode	Authentication mode for PPPoE dial-up. PAP: Passwords are sent over links in plain text. After a PPP link is established, the authenticated device repeatedly sends the user name and password until the authentication finishes. This mode cannot ensure high security. CHAP: a three-way handshake authentication protocol. In CHAP authentication, the authenticated device sends only the user name to the authenticating device. Compared with PAP, CHAP features higher security because passwords are not transmitted.
Default route	Configure a default route from the local hosts to the PPPoE server.
Load balancing	Two load balancing modes are supported: UCMP: Unequal Cost Multiple Path ECMP: Equal Cost Multiple Path
Interface bandwidth (Kbps)	When the load balancing mode is UCMP, the interface bandwidth needs to be configured.
TCP-MSS (bytes)	MSS of TCP packets on an interface. The MSS refers to the maximum length of a TCP packet segment sent from the peer device to the local device. During TCP connection negotiation, devices at both ends record the MSS of each other. When sending TCP packets, the devices limit the size of TCP packets within the MSS.
VPN instance	VPN instance bound to an interface. NOTE: Before setting this parameter, you must create an IPv4 VPN instance. For the detailed procedure, see VPN Instance.
