Description Use the clock command to set the clock mode for an ATM E1/T1 interface. Use the undo clock command to restore the default, that is, the slave clock mode. For ATM E1/T1 interfaces operating as DCEs, set the clock mode to master. For interfaces operating as DTEs, set the clock mode to slave.

Description Use the baudrate command to set the baud rate for a serial interface. Use the undo baudrate command to restore the default.
As DTE, the interface accepts the clock provided by the DCE. As 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, four clock options are available for a DTE device.

Description Use the code command to set the digital signal coding format on the synchronous serial interface. Use the undo code command to restore the default, that is, NRZ.
description Syntax description text undo description View Serial interface view Default Level 2: System level Parameters text: interface description, which is a string of 1 to 80 characters. Description Use the description command to configure the interface description. Use the undo description command to restore the default. By default, the description of an interface is its interface name followed by the Interface string, Serial2/0/0 Interface for example.
When determining whether a synchronous serial interface is up or down, the system by default detects the DSR signal, DCD signal, and presence of cable connection. Only when the three signals are all valid will the interface be regarded up. If level detection is disabled, the system considers that the interface is up with both DTR and DSR being up after detecting the cable connection.

Use the undo shutdown command to enable an interface. By default, an interface is enabled. In certain circumstances, modification to the interface parameters does not immediately take effect, and therefore, you need to re-enable the interface to make the modification work.

Examples # Set the framing format of interface T1 2/0/0 to SF. <Sysname> system-view [Sysname] controller t1 2/0/0 [Sysname-T1 2/0/0] frame-format sf idlecode (CT1 interface) Syntax idlecode { 7e | ff } undo idlecode View CT1 interface view Default Level 2: System level Parameters 7e: Sets the line idle code to 0x7E.
type { 7e | ff }: Sets the interframe filling tag to 0x7E by specifying the 7e keyword or to 0xFF by specifying the ff keyword. On CT1 interfaces, the default interframe filling tag is 0x7E. Description Use the itf command to set the type and the number of interframe filling tags on the CT1 interface. Two types of interframe filling tag are available: 0x7E and 0xFF.
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. fdl-ansi-plb-up: Sends ANSI-compliant payload loopback (PLB) activation request code in the FDL to start remote loopback.
Description Use the shutdown command to shut down the current CT1 interface. Use the undo shutdown command to bring up the current CT1 interface. By default, an interface is enabled. Examples # Shut down T1 2/0/0. <Sysname> system-view [Sysname] controller t1 2/0/0 [Sysname-T1 2/0/0] shutdown E1-F Interface Configuration Commands Syntax...
Parameters serial interface-number: Specifies a serial interface by its number. If no interface is specified, information about all the E1-F interfaces is displayed. Description Use the display fe1 serial command to display the configuration and state information about the specified or all E1-F interfaces. If the specified interface is a common serial interface rather than an E1-F interface, the system will display the prompt.
Parameters detect-timer: Period to check error packets, in the range 30 to 600 (in seconds). renew-timer: Period after which an interface resumes it function, in the range 120 to 2,400 (in seconds). threshold: Ratio of error packets in percentage, in the range 5 to 100. Description Use the error-diffusion restraint config command to set the three parameters in error packets diffusion restraint.
Parameters long: Supports long cables. short: Supports short cables. Description Use the fe1 cable command to set the cable length for an E1-F interface. Use the undo fe1 cable command to restore the default. By default, the long keyword applies. Examples # Set the cable length type on E1-F interface Serial 2/0/0 to short.
View E1-F interface view Default Level 2: System level Parameters ami: Uses AMI line code format. hdb3: Uses HDB3 line code format. Description Use the fe1 code command to set the line code format for the E1-F interface. Use the undo fe1 code command to restore the default, that is, HDB3. The default line code format for an E1-F interface is HDB3.
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 at least at least one out of every eight bits is a one.
Parameters crc4: Sets the framing format to CRC4. no-crc4: Sets the framing format to no-CRC4. Description Use the fe1 frame-format command to configure the framing format of the E1-F interface. Use the undo fe1 frame-format command to restore the default, that is, no-CRC4. An E1-F interface in framed mode supports both CRC4 and no-CRC4 framing formats, where CRC4 supports four-bit CRC on physical frames while no-CRC4 does not.
View E1-F interface view Default Level 2: System level Parameters number number: Sets the number of interframe filling tags (an interframe filling tag is one byte in length). The number argument ranges from 0 to 14. type { 7e | ff }: Sets the type of interframe filling tag to 0x7E by specifying the 7e keyword or to 0xFF by specifying the ff keyword.
Use the undo fe1 loopback command to restore the default. By default, loopback is disabled. Loopback is intended for checking the condition of interfaces or cables. Disable it otherwise. The three loopback modes cannot be used at the same time on an E1-F interface. Examples # Set E1-F interface Serial 2/0/0 in internal loopback mode.
Timeslot 0 on E1-F interfaces is used for synchronization. Therefore, a bundling operation only involves timeslots 1 through 31. When the E1-F interface is working in unframed mode, the fe1 timeslot-list command is invalid. Related commands: fe1 unframed. Examples # Bundle timeslots 1, 2, 5, 10 through 15, and 18 on E1-F interface Serial 2/0/0. <Sysname>...

A rich set of overhead bytes are available to implement operation, administration, and maintenance (OAM) functions such as hierarchical management of transmission networks for SONET/SDH frames. Among these overhead bytes, J1 and C2 are higher-order path overhead bytes. The J1 byte is used for detecting the continuity of the connection between two interfaces at the path layer.

SDH provides two payload mapping/multiplexing solutions: ANSI and ETSI. ANSI uses the AU-3 multiplexing scheme, where the lower-order payload is aggregated into the VC-3 higher-order path. VC-3 plus an AU pointer forms AU-3. Three such AU-3s can be synchronized and multiplexed to form one AUG. ETSI uses the AU-4 multiplexing scheme, where the lower-order payload is aggregated into the VC-4 higher-order path.
