Do AR routers support POS interfaces

6

POS interfaces that AR routers support are described as follows:

1STM1, ISTM4, and 4STM1 interface cards support POS interfaces.
Currently, AR2200, AR3200, AR3600, AR2200-S, and AR3200-S series devices support ISTM1, ISTM4, and 4STM1 interface cards. NE16EX series devices support only 1STM1 and 1STM4 interface cards.
- A 1STM1 interface card provides a POS optical interface with a rate of 155 Mbit/s.
- A 1STM4 interface card provides a POS optical interface with a rate of 622 Mbit/s.
- A 4STM1 interface card provides four POS optical interfaces with a rate of 155 Mbit/s or a POS optical interface with a rate of 622 Mbit/s (interface 0 is available and interface 1/2/3 are disabled).

How to configure the POS interface of an AR router
You can configure the POS interface of an AR router as follows: # Before configuring the POS interface, you must register the 1STM1/1STM4/4STM1 interface card. The parameters and configurations of the POS interfaces on both ends must be consistent except for the clock mode. [Huawei] interface pos 2/0/0 [RouterA-Pos2/0/0] frame-format sonet //Set the frame format of the POS interface to SONET. [RouterA-Pos2/0/0] link-protocol hdlc //Set the link-layer protocol of the POS interface to HDLC. [RouterA-Pos2/0/0] clock slave //Set the clock mode of the POS interface to slave. [RouterA-Pos2/0/0] mtu 1200 //Set the MTU value of the POS interface to 1200. [RouterA-Pos2/0/0] flag c2 3 //Set the overhead bytes of the POS interface. [RouterA-Pos2/0/0] flag j0 16byte-mode abc [RouterA-Pos2/0/0] flag j1 16byte-mode xyz [RouterA-Pos2/0/0] undo scramble //Disable the load scrambling function of the POS interface. [RouterA-Pos2/0/0] crc 16 //Set the CRC verification mode of the POS interface to CRC-16. [Huawei-Pos2/0/0] threshold sd 8 //Set the SD alarm threshold of the POS interface to 10e-8. [Huawei-Pos2/0/0] threshold sf 5 //Set the SF alarm threshold of the POS interface to 10e-5. The SD alarm threshold must be smaller than the SF alarm threshold. Run the display interface pos 2/0/0 command to check the configuration and status of the POS interface. Run the display interface brief command to check the brief information about the POS interface.

Do AR routers support E1 interfaces
E1 interfaces that AR routers support are described as follows: E1 interfaces are configured on E1/T1 cards and can be seen as serial interfaces (currently supported by AR1200/AR2200/AR3200/AR3600). - 1E1T1-M/2E1T1-M support the E1/CE1/CT1/PRI(E1&T1) interface. - 4E1T1-M/8E1T1-M support the E1/CE1/PRI(E1) interface. - 1E1T1-F/2E1T1-F support the framed/unframed E1/T1 interface. - 4E1T1-F/8E1T1-F support the framed/unframed E1 interface.

Do AR routers support 1000M interfaces
GE interfaces displayed on the equipment panel are 1000M Ethernet interfaces. The rate of a GE interface is 100 Mbit/s by default when it works in non-auto negotiation mode. If you want to change the rate to 1000 Mbit/s, run the following commands:
#Set the rate of the interface GE2/0/0 in non-auto negotiation mode to 1000 Mbit/s.
system-view
[Huawei] interface gigabitethernet 2/0/0
[Huawei-GigabitEthernet2/0/0] undo negotiation auto
[Huawei-GigabitEthernet2/0/0] speed 1000


Does the LTE cellular interface support PPP
The LTE cellular interface supports PPP. The following physical interfaces also support PPP: - Synchronous or asynchronous serial interface working in synchronous mode (the interface type is the serial interface) - Async interface working in protocol mode - Serial interfaces formed by CE1/PRI or CT1/PRI interfaces, which have the same logical features as synchronous serial interfaces - Serial interfaces formed by CE3 or CT3 interfaces, which have the same logical features as synchronous serial interfaces - Serial interfaces formed by E1-F or T1-F interfaces, which have the same logical features as synchronous serial interfaces - Serial interfaces formed by E1/T1 channels that are channelized from a CPOS interface, which have the same logical features as synchronous serial interfaces - Cellular interfaces - ISDN BRI interfaces - POS interfaces Note: For LTE cellular interfaces, only the E392 data cards support the link-protocol ppp command.

Do AR routers support BNC interfaces?
The E1 cards of AR routers use 75-ohm DB9-BNC cables or RJ45-BNC cables to support BNC interfaces. E1 cards and the cables that they support are described in the table in the right column.
