Usage guidelines If the upper layer protocol of an interface is PPP, FR, or HDLC, the link layer sends keepalive packets to the peer. If it cannot receive any keepalive packets sent by the peer, the link layer considers the peer is faulty and shuts down the interface. You can use this command to modify the interval at which the interface sends keepalive packets. Configure a reasonable value for the interval on a low-speed link.
protocol: Configures the interface to operate in protocol mode. In this mode, the interface uses configured link layer protocol parameters to set up a link with the remote end after its physical link is established. Usage guidelines You can configure this command for a synchronous/asynchronous interface only after you change the mode of the interface to asynchronous mode with the physical-mode async command.
When you specify a baud rate for a synchronous serial interface, you must make sure the baud rate matches the cable type. • For V.24 DTE/DCE, set the baud rate in the range of 1200 bps to 64000 bps. • For V.35 DCE/DCE, X.21 DTE/DCE, EIA/TIA-449 DTE/DCE, and EIA-530 DTE/DCE, set the baud rate in the range of 1200 bps to 4096000 bps. The baud rate adopted by a DCE-DTE pair is determined by the DCE. Examples # Set the baud rate of synchronous serial interface 2/0 at DCE side to 115200 bps.
Usage guidelines A synchronous serial interface can operate as a DCE or DTE. • As a DCE, the interface provides DCEclk clock to the DTE. • As a DTE, the interface accepts the clock provided by the DCE. Because transmitting and receiving clocks of synchronization devices are independent, the receiving clock of a DTE device can be either the transmitting or receiving clock of the DCE device, so is the transmitting clock. Therefore, five clock options are available for a DTE device.
code Use code to configure the digital signal coding format on a synchronous serial interface. Use undo code to restore the default. Syntax code { nrz | nrzi } undo code Default The digital signal coding format is NRZ. Views Synchronous serial interface view Predefined user roles network-admin Parameters nrz: Sets the digital signal coding format to nonreturn to zero (NRZ). nrzi: Sets the digital signal coding format to nonreturn to zero inverted (NRZI).

Examples # Configure synchronous serial interface Serial 2/0 to adopt 32-bit CRC. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] crc 32 detect dcd Use detect dcd to enable data carrier detection (DCD) on a serial interface. Use undo detect dcd to disable DCD on a serial interface. Syntax detect dcd undo detect dcd Default DCD is enabled on a serial interface.
Default Level detection is enabled on a serial interface. Views Synchronous serial interface view, asynchronous interface view, synchronous/asynchronous interface view Predefined user roles network-admin Usage guidelines If level detection is disabled on an asynchronous serial interface, the system automatically reports that the state of the serial interface is up with both DTR and DSR being up without detecting whether a cable is connected.

Usage guidelines Facility Data Link (FDL) is an embedded 4 kbps overhead channel within the ESF format for transmitting alarm information, performance statistics, or loopback code. FDL uses ANSI T1.403 and ATT TR 54016.
Usage guidelines CT1/PRI interfaces support two framing formats, SF and ESF. In SF format, multiple frames can share the same FSC and signaling information, so that more significant bits are available for transmitting user data. The use of ESF allows you to test the system without affecting the ongoing service. Examples # Set the framing format of interface T1 2/0 to SF.
Syntax itf { number number | type { 7e | ff } } undo itf { number | type } Default The interframe filling tag is 0x7E, and the number of interframe filling tags is 4. Views CT1/PRI interface view Predefined user roles network-admin Parameters number number: Sets the number of interframe filling tags (an interframe filling tag is one byte in length), in the range of 0 to 14. type { 7e | ff }: Sets the interframe filling tag to 0x7E by specifying the 7e keyword or to 0xFF by specifying the ff keyword.
Parameters local: Enables the CT1/PRI interface to perform local loopback. payload: Enables the interface to perform external payload loopback. remote: Enables the interface to perform remote loopback. Usage guidelines Loopback is mainly used to check the condition of interfaces or cables. Disable loopback in other cases. You can bundle timeslots on a CT1/PRI interface to form a serial interface and encapsulate it with PPP.
For the PRI set, the system automatically creates a serial interface that is logically equivalent to an ISDN PRI interface. The serial interface is named in the form of serial number:23, where number is the number of the CT1/PRI interface on which the serial interface is created. Because a channel set and a PRI set cannot coexist on a CT1/PRI interface, your PRI set creation attempt will fail if the channel-set command is configured.
Default No remote loopback control code is sent. Views CT1/PRI interface view Predefined user roles network-admin Parameters fdl-ansi-llb-down: Sends ANSI-compliant LLB deactivation request code in the FDL to remove loopback. fdl-ansi-llb-up: Sends ANSI-compliant line loopback (LLB) activation request code in the FDL to start remote loopback. fdl-ansi-plb-down: Sends ANSI-compliant PLB deactivation request code in the FDL to remove loopback.

Views T1-F interface view Predefined user roles network-admin Parameters inverted: Enables user data inversion. normal: Disables user data inversion. Usage guidelines To prevent 7e in valid data from being taken for stuffing characters, HDLC inserts a zero after every five ones in the data stream. Then, HDLC inverts every one bit into a zero and every zero bit into a one. This ensures that at least at least one out of every eight bits is a one.
Usage guidelines FDL is an embedded 4 kbps overhead channel within the ESF format for transmitting performance statistics or loopback code. You can change the setting depending on the setting at the far end. Examples # Set ANSI FDL on T1-F interface Serial 2/0. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] ft1 fdl ansi Related commands ft1 frame-format ft1 frame-format Use ft1 frame-format to set the framing format on the T1-F interface.
