Syntax e1 line-number set clock { master | slave } undo e1 line-number set clock Default The clock source for an E1 line on the CE3 interface is line clock. Views CE3 interface view Default command level 2: System level Parameters line-number: E1 line number in the range of 1 to 16. master: Adopts the internal clock as the clock source.
Default command level 2: System level Parameters line-number: E1 line number in the range of 1 to 16. crc4: Sets the frame format to CRC4. no-crc4: Sets the frame format to no-CRC4. Usage guidelines Configure this command only when the specified E1 line is working in framed format (which can be set using the undo e1 unframed command). Examples # Set the framing format to CRC4 for the first E1 line on interface E3 2/0/0.
Examples # Set the first E1 line on interface E3 2/0/0 in internal loopback mode. system-view [Sysname] controller e3 2/0/0 [Sysname-E3 2/0/0] e1 1 set loopback local e1 shutdown Use e1 shutdown to shut down an E1 line on the CE3 interface. Use undo e1 shutdown to restore the default. Syntax e1 line-number shutdown undo e1 line-number shutdown Default E1 lines are up.
Default An E1 line operates in framed mode (CE1 mode). Views CE3 interface view Default command level 2: System level Parameters line-number: E1 line number in the range of 1 to 16. Usage guidelines An E1 line in unframed mode does not contain the frame control information; it cannot be divided into timeslots. The system automatically creates a serial interface numbered serial number/line-number:0 for it.
1: Specifies the Kentrox mode, where the subrate is a multiple of 500 kbps and is in the range of 500 to 24500 kbps. In this mode, the subrate can also be 34010 kbps (making a total of 50 rate levels). subrate number: Specifies the subrate for the CE3 interface. The number argument is in the range of 1 to 34010 (in kbps). Usage guidelines FE3 mode is a non-standard E3 application mode. In this mode, the subrate level setting varies with vendors.
payload: Enables external payload loopback on the CE3 interface. remote: Enables external loopback on the CE3 interface. Usage guidelines Loopback is intended for test use. Disable loopback in other cases. If a CE3 interface encapsulated with PPP is placed in a loopback, it is normal that the state of the link layer protocol is reported as down. Examples # Enable internal loopback on interface E3 2/0/0.
reset counters controller e3 Use reset counters controller e3 to clear the controller counter of a CE3 interface. Syntax reset counters controller e3 interface-number Views User view Default command level 2: System level Parameters interface-number: Interface number. Usage guidelines You can use the display controller e3 command to display the statistics collected by the controller counters of CE3 interfaces. The reset counters interface command clears the counters of all interfaces.
When the CE3 interface is operating in unchannelized mode, the system automatically creates a serial interface numbered serial number/0:0 for it. This interface operates at 34.368 Mbps and is logically equivalent to a synchronous serial interface on which you can make other configurations. Examples # Configure interface E3 2/0/0 to operate in unchannelized mode.
The supported alarm signals, LOS, LOF, AIS, RAI, FEBE, and idle, are ANSI T1.107-1995 compliant. You can only configure the CT3 interface to send a type of alarm signal. To have the interface send another type of signal, use the undo alarm command to remove the previous setting first. In addition, when the RAI signal generated upon detection of the LOS, LOF, or AIS signal is present, the CT3 interface cannot send another type of signal.
Usage guidelines ITU O.151, ITU O.153, and ANSI T1.403-1999 define many BERT patterns, among which, the CT3 interface supports only 2^7, 2^11, 2^15, and QRSS. When running a BERT test, the local end sends out a pattern, which is to be looped over somewhere on the line and back to the local end. The local end then examines the received pattern for bit error rate to help you identify whether the condition of the line is good.

In conjunction with the t3 keyword, it specifies a CT3 interface. |: Filters command output by specifying a regular expression.
Periodical detection is enabled, no code received now.
Field Description Type of the received alarm: none, LOS, LOF, RAI, or AIS. Receiver alarm state If a LOS, LOF, AIS was received, RAI would be sent and the screen displayed "Transmitter is sending RAI" instead. MDL state MDL state. No message is sent now. No MDL message is being sent. If an MDL message, path or idle-signal for example, was being sent, the screen would display "Message sent now: path. idle signal." Message data elements MDL data elements.
Field Description Last clearing of counters Time when counters were last cleared, for example, 14:39:02 UTC Sat 06/25/2005. If no clearing is performed, "Never" is displayed. Data in current interval: Statistics spanning the current 15-minute interval, coving the counts of these items: Line Code Violations Line code violations: BPV, or EXZ. Far End Block Error Far-end block error. C-Bit Coding Violation C-bit coding violation. P-bit Coding Violation P-bit coding violation.
Field Description Bits received (since test started) Number of bits received since start of the BERT test. Bit errors (since latest sync) Number of bit errors received since last synchronization. Bits received (since latest sync) Number of bits received since last synchronization. feac Use feac to enable FEAC channel signal detection and sending on the CT3 interface. Use undo feac to remove the current FEAC settings.
Disable FEAC detection before you configure far-end loopback to prevent loopback deadlock, which may happen when the local end enables loopback after detecting the loopback code sent back by the far end. You may view the transmitting/receiving state of the FEAC channel by using the display controller t3 command. Examples # Enable FEAC channel signal detection on CT3 interface T3 2/0/0.
ft3 Use ft3 to configure a CT3 interface to operate in the FT3 mode and set the DSU mode or the subrate. Use undo ft3 to restore the default. Syntax ft3 { dsu-mode { 0 | 1 | 2 | 3 | 4 } | subrate number } undo ft3 { dsu-mode | subrate } Default DSU mode 0 (the Digital Link mode) is adopted, and the subrate is 44210 kbps. Views CT3 interface (in FT3 mode) view Default command level 2: System level Parameters dsu-mode: Specifies the FT3 (Fractional T3) DSU mode for a CT3 interface operating in FT3 mode.
You can use the display interface serial interface-number:0 command to check the DSU mode setting, the subrate, the actual rate, and the baudrate of a CT3 interface. The actual rate does not count in the overhead bits, and the baudrate is the actual T3 line rate (44736 kbps), with the overhead bits counted in. Examples # Configure T3 2/0/0 interface to operate in the FT3 mode, setting the DSU mode to 1 and the subrate to 3000 kbps.
Syntax loopback { local | payload | remote } undo loopback Default Loopback is disabled on CT3 interfaces. Views CT3 interface view Default command level 2: System level Parameters local: Enables internal loopback on the CT3 interface. payload: Enables external payload loopback on the CT3 interface. remote: Enables external loopback on the CT3 interface.

The system default is line.
Syntax reset counters controller t3 interface-number Views User view Default command level 2: System level Parameters interface-number: Interface number. Usage guidelines You can use the display controller t3 command to display the statistics collected by the controller counters of CT3 interfaces. The reset counters interface command clears the counters of all interfaces. To clear the controller counter of individual CT3 interfaces, use the reset counters controller t3 command.
Usage guidelines At the startup of the router, periodical alarm signal detection is enabled on all T1 lines on the CT3 interface. When a T1 line detects LOS, LOF, or AIS signals, it sends RAI signals to its peer. Alarm state report for the interface is real time; you may view that with the display controller t3 command. The supported alarm signals, LOS, LOF, AIS, RAI, FEBE, and idle, are ANSI T1.403 compliant. You can configure a T1 line to send only a type of alarm signal.
qrss: Specifies the length of transmitted BERT pattern, in bits, as two to the twentieth power. In this pattern, the presence of 14 or more consecutive zeros is not allowed. time number: Sets the duration of a BERT test, in the range of 1 to 1440 minutes. unframed: Sets the test pattern to cover the overhead bits of the frame. Usage guidelines ITU O.151, ITU O.153, and ANSI T1.403-1999 define many BERT patterns, among which, T1 lines on CT3 interfaces support only 2^11, 2^15, 2^20, 2^23, and QRSS.
speed { 56k | 64k }: Speed of the timeslot bundle (the channel set) in kbps. If 56k is selected, the timeslots is bundled into an N × 56 kbps bundle. If 64k, the default, is selected, the timeslots is bundled into an N × 64 kbps bundle. Usage guidelines When a T1 line is operating in framed (CT1) mode, you can bundle timeslots on it. For each channel set thus formed, the system automatically creates a serial interface numbered serial number/line-number:set-number.
Usage guidelines Loopback is an effective way of diagnosis. You may place a far-end device into loopback mode either at command line on it or by sending loopback control code to it. The types and formats of loopback control code supported on T1 interfaces are compliant with ANSI T1.403. Loopback can be divided into line loopback and payload loopback. They differ in the sense that the data stream is looped back at the framer with line loopback but not with payload loopback.

e1 shutdown Use e1 shutdown to shut down an E1 channel. Use undo e1 shutdown to bring up an E1 channel. Syntax e1 e1-number shutdown undo e1 e1-number shutdown Default E1 channels are up. Views CPOS interface view Default command level 2: System level Parameters e1-number: Number of an E1 channel on the CPOS interface, in the range of 1 to 63. Usage guidelines Shutting down an E1 channel also shuts down the serial interfaces that are formed on it. Examples # Shut down E1 channel 1.
Usage guidelines So far, E1 channels on CPOS interfaces support two operating modes: clear channel (or unframed) and channelized (or framed). • In unframed mode, an E1 channel can form a 2.048 Mbps serial interface without timeslot division. It is named serial slot/port/e1-number:0. • In framed mode, all timeslots except timeslot 0 on the E1 channel can be bundled arbitrarily to form serial interfaces. Examples # Set E1 channel 3 on interface CPOS 2/0/0 to operate in unframed mode.

In case of an up or down event, the CPOS interface comes up or goes down after the physical state change suppression interval. Use undo link-delay to restore the default. Syntax link-delay seconds undo link-delay Default Physical state change suppression is disabled on a CPOS interface.
undo loopback Default Loopback is disabled. Views CPOS interface view Default command level 2: System level Parameters local: Internal loopback, used for testing the physical interface itself. remote: External loopback, used for testing the cable connected to the interface. Usage guidelines Loopback is intended for test use. Disable it otherwise. Examples # Enable external loopback testing on interface CPOS 2/0/0.
• ETSI uses the AU-4 multiplexing scheme, where the lower-order payload is aggregated into the VC-4 higher-order path. VC-4 plus an AU pointer forms an AU-4. This AU-4 can be synchronized and multiplexed to form one AUG. When the CPOS interface is operating in SDH mode, you can choose to multiplex AUG to AU-4 or AU-3 by using the multiplex mode command. When the CPOS interface is operating in SONET mode, AUG can be multiplexed only to AU-3 and the multiplex mode command is invalid.

Related commands display controller cpos t1 t1 shutdown Use t1 shutdown to shut down a T1 channel. Use undo t1 shutdown to bring up a T1 channel. Syntax t1 t1-number shutdown undo t1 t1-number shutdown Default T1 channels are up. Views CPOS interface view Default command level 2: System level Parameters t1-number: Number of a T1 channel on the CPOS interface, in the range of 1 to 84. Usage guidelines Disabling a T1 channel disables the serial interfaces formed on it.
Parameters t1-number: Number of a T1 channel on the CPOS interface, in the range of 1 to 84. Usage guidelines Like E1 channels, T1 channels on CPOS interfaces support unframed (clear channel) mode and framed (channelized) mode. • In unframed mode, a T1 channel can form a 1.544 Mbps serial interface without timeslot division. This interface is named serial slot/card/t1-number:0. • In framed mode, 24 timeslots of a T1 channel can be bound randomly to form serial interfaces.
At startup of your device, periodical alarm signal detection is enabled on T3 channels. When detecting LOS, LOF, or AIS signals, a T3 channel sends RAI signals to its peer. Alarm state report for the interface is real time. You can view that by executing the display controller cpos t3 command. The supported alarm signals, LOS, LOF, AIS, RAI, FEBE, and idle, are ANSI T1.107-1995 compliant. Only a type of alarm signal can be sent on a T3 channel at a time.
time-number: Duration of a BERT test, in the range of 1 to 1440 minutes. Usage guidelines ITU O.151, ITU O.153, and ANSI T1.403-1999 define many BERT patterns, among which 2^7, 2^11, 2^15, and QRSS are supported. When running a BERT test, the local end sends out a pattern, which is looped over somewhere on the line and back to the local end. The local end then examines the received pattern for the bit error rate to help you determine whether the condition of the line is good.
Configure the clock mode of a T3 channel the same as the global clock mode. Examples # Configure the clock mode as master for the T3 channel 3 on CPOS 2/0/0. system-view [Sysname] controller cpos 2/0/0 [Sysname-Cpos2/0/0] t3 3 set clock master t3 set feac Use t3 set feac to enable FEAC channel signal detection or FEAC signal sending on the specified T3 interface. Use undo t3 set feac to remove the current FEAC settings.
According to ANSI T1.107a, the framing format used by FEAC channels is bit oriented protocol (BOP). At the startup of your device, FEAC signal detection is enabled while FEAC signal sending is disabled on a T3 interface. Disable FEAC signal detection before you configure far-end loopback to prevent loopback deadlock, which might happen when the local end enables loopback after detecting the loopback code sent back by the far end.
system-view [Sysname] controller cpos 2/0/0 [Sysname-Cpos2/0/0] t3 1 set frame-format m23 Related commands t3 set feac t3 set loopback Use t3 set loopback to enable a type of loopback on the specified T3 channel.
