CPOS interface commands -- alarm-detect

| NOTE: Support for this command depends on the device model.

‌

Use alarm-detect to configure the action to take when an RDI, SD, or SF alarm occurs on an interface.

Use undo alarm-detect to restore the default.

Syntax

alarm-detect { rdi | sd | sf } action link-down

undo alarm-detect { rdi | sd | sf }

Default

The device does not take any actions on the interface when an RDI, SD, or SF alarm occurs.

Parameters

rdi: Specifies remote defect indication (RDI) alarms.

sd: Specifies signal degrade (SD) alarms.

sf: Specifies signal fail (SF) alarms.

action: Specifies the action to take when the specified alarm is detected on the interface.

link-down: Places the interface in down state.

Usage guidelines

An RDI alarm occurs if the device receives multiplexer section remote defect indication (MS-RDI) signals from the remote end.

An SD or SF alarm occurs if the bit error rate of incoming packets crosses the SD or SF alarm threshold. To set the SD or SF alarm threshold, use the threshold command.

Examples

# Configure CPOS 2/2/1 to go down when an SD alarm occurs.

<Sysname> system-view

CPOS interface commands -- channel-align-mode

| NOTE: Support for this command depends on the device model.

‌

Use channel-align-mode to set the E1 channel alignment mode on a CPOS interface.

Use undo channel-align-mode to restore the default.

Syntax

channel-align-mode { alcatel | lucent }

undo channel-align-mode

Default

The default setting varies by device model.

mdc-admin

Parameters

alcatel: Specifies Alcatel mode.

lucent: Specifies Lucent mode.

Usage guidelines

For E1 channels to operate correctly, channel number assignment must meet the following requirements:

· If this command is configured, use the same channel number assignment scheme as the peer end. For example, to communicate with channel 5 on a Lucent-mode CPOS interface, configure channel 5 on the local interface.

· If this command is not configured, you must map the channel number assignment schemes between the two ends. For example, to communicate with channel 25 on a Lucent-mode CPOS interface, you must configure channel 5 on the local interface.

You must execute this command before using the e1 channel-set or e1 unframed command.

Examples

# Set the E1 channel alignment mode to Alcatel on CPOS 2/2/1.

<Sysname> system-view

[Sysname] controller cpos 2/2/1

[Sysname-Cpos2/2/1] channel-align-mode alcatel

Use undo clock to restore the default.

Syntax

clock { master | slave }

undo clock

Default

The clock mode of a CPOS interface is slave.

mdc-admin

Parameters

master: Sets the clock mode to master.

slave: Sets the clock mode to slave.

Usage guidelines

When the clock mode of a CPOS interface is master, it uses the internal clock source.

When the clock mode of a CPOS interface is slave, it uses the line clock source.

When connected to a SONET/SDH device, the CPOS interface must use the slave clock mode. The SONET/SDH network clock is more precise.

When two CPOS interfaces are directly connected, you must configure the two ends with different clock modes.

Examples

# Set the clock mode to master for CPOS 2/2/1.

<Sysname> system-view

[Sysname] controller cpos 2/2/1

Parameters

e1-number: Specifies the number of an E1 channel on the CPOS interface. The value range for this argument is 1 to 63.

set-number: Specifies a channel set number in the range of 0 to 30.

timeslot-list range: Specifies a comma-separated list of timeslot items. An item can be an individual timeslot or a timeslot range. Use a hyphen (-) to separate the start and end timeslot numbers of a range. The value range for the timeslot number is 1 to 31.

Usage guidelines

When the E1 channel is channelized, timeslot 0 is used for synchronization. The other 31 timeslots can be bundled to form one or multiple channel sets. For each channel set, the system automatically creates a serial interface numbered in the format interface number/channel number:channel set number.

For successful communication, make sure the local end has the same timeslot bundling settings as the remote end.

Examples

# Bundle timeslots 1 to 31 into a channel set on E1 channel 63.

Parameters

e1-number: Specifies the number of an E1 channel on the CPOS interface. The value range for this argument is 1 to 63.

master: Sets the clock mode to master.

Usage guidelines

The clock mode settings of E1 channels on a CPOS interface are independent of one another.

Set the clock mode on an E1 channel depending on its connected device.

· If the connected device is a SONET/SDH device, enable the slave clock mode on the channel. The SONET/SDH network clock is more precise than the clock provided by the device.

· If the E1 channel is directly connected to a router, make sure the E1 channel uses a different clock mode than the peer end.

Examples

# Set the clock mode to master on E1 channel 1.

The clock mode settings of E3 channels on a CPOS interface are independent of one another.

Set the clock mode on an E3 channel depending on its connected device.

· If the connected device is a SONET/SDH device, enable the slave clock mode on the channel. The SONET/SDH network clock is more precise than the clock provided by the device.

· If the E3 channel is directly connected to a router, make sure the E1 channel uses a different clock mode than the peer end.

As a best practice, configure the same clock mode of an E3 channel as the global clock mode.

Examples

# Set the clock mode to master on E3 channel 1 of CPOS 2/2/1.

Parameters

e3-number: Specifies the number of an E3 channel on the CPOS interface. The value range for this argument is 1 to 3.

dsu-mode: Specifies the DSU mode for an E3 channel operating in FE3 mode.

Table 9 FE3 DSU mode options

Keyword | DSU mode (vendor) | Subrate range | Total number of subrate grades

1 | Kentrox | 500 to 24500 kbps in steps of 500 kbps 34010 kbps | 50

‌

subrate sub-number: Specifies an FE3 subrate. The value range for the sub-number argument is 1 to 34010 kbps.

Usage guidelines

FE3 (also called subrate E3) is a nonstandard E3 application. FE3 subrate ranges and the number of subrate grades vary by vendor. You can use the fe3 command to configure the device to be compatible with the FE3 DSU modes listed in Table 9.

The subrates available in the DSU mode set with the fe3 dsu-mode command are discrete. The subrate set with the fe3 subrate command is approximate rather than exact. After you set a subrate, the E3 interface calculates the precise subrate (in bps) closest to the approximate subrate within the subrate range available in the specified DSU mode. The calculated precise subrate is the subrate actually applied to the hardware circuit.

To display the DSU mode, configured subrate, actual rate, and baud rate of an E3 interface, use the display interface serial interface-number:0 command. The actual rate of the E3 interface is the pure data bandwidth excluding the bandwidth for overhead bytes. The baud rate of the E3 interface, 34368 kbps, is the actual rate of the E3 circuit, including the bandwidth for the overhead bytes.

Examples

# Configure E3 channel 1 on CPOS 2/2/1 to operate in DSU mode 1 and set its subrate to 500 kbps.

<Sysname> system-view

‌

subrate sub-number: Sets the FT3 subrate, in the range of 1 to 44210 kbps.

Usage guidelines

FT3 (also called subrate T3) is a nonstandard T3 application. FT3 subrate ranges and the number of subrate grades vary by vendor. You can use the ft3 command to configure the device to be compatible with the FT3 DSU modes listed in Table 10.

The subrates available in the DSU mode set with the ft3 dsu-mode command are discrete. The subrate set with the ft3 subrate command is approximate rather than exact. After you set a subrate, the T3 interface calculates the precise subrate (in bps) closest to the approximate subrate within the subrate range available in the specified DSU mode. The calculated precise subrate is the subrate actually applied to the hardware circuit.

To display the DSU mode, configured subrate, actual rate, and baud rate of a T3 interface, use the display interface serial interface-number:0 command. The actual rate of the T3 interface is the pure data bandwidth excluding the bandwidth for overhead bytes. The baud rate of the T3 interface, 44736 kbps, is the actual rate of the T3 circuit, including the bandwidth for the overhead bytes.

Views

CPOS interface view

Predefined user roles

network-admin

mdc-admin

Parameters

seconds: Sets the physical state change suppression interval in seconds. The value range varies by device model.

Usage guidelines

When the physical state changes, a CPOS interface reports the event to the upper-layer modules, and generates log and SNMP notification messages. To reduce system overhead caused by frequent physical state changes, use this command to suppress physical state changes within an interval. The interface will ignore any changes that occur during each suppression interval. When the suppression interval expires, the interface will not report the change event or generate messages if the change is removed.

For example, the suppression interval starts when the interface changes from up to down. The interface reports the change event and generates messages if it is still down when the interval expires. The interface does not report the change event or generate messages if it is up when the interval expires.

This command suppresses up state change, down state change, or both depending on the device model.

Examples

# Set the physical state change suppression interval to 8 seconds on CPOS 2/2/1.

Parameters

au-3: Gets AUG through AU-3.

au-4: Gets AUG through AU-4.

Usage guidelines

SDH provides the following payload mapping/multiplexing solutions:

· ANSI—Uses the AU-3 multiplexing scheme. This scheme multiplexes the lower-order payload to 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. This scheme multiplexes the lower-order payload to 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 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. The multiplex mode command does not take effect.

Countries and regions use different multiplexing schemes. You must use the same multiplexing scheme as the peer device. For example, the AU-4 multiplexing scheme is used in China.

# In SDH mode, multiplex AUG to AU-3.

A T1 channel in channelized mode is divided into 24 timeslots numbered 1 through 24. The 24 timeslots can be bundled to form one or multiple channel sets. For each channel set, the system automatically creates a serial interface numbered in the format interface number/channel number:channel set number.

For successful communication, make sure the local end has the same timeslot bundling settings as the remote end.

Examples

# Bundle timeslots 1 through 23 into a channel set on T1 channel 1.

<Sysname> system-view

[Sysname] controller cpos 2/2/1

Parameters

t1-number: Specifies the number of a T1 channel on the CPOS interface. The value range for this argument is 1 to 84.

master: Sets the clock mode to master.

slave: Sets the clock mode to slave.

Usage guidelines

The clock mode settings of the T1 channels on a CPOS interface are independent of one another.

Set the clock mode on a T1 channel depending on its connected device.

· If the connected device is a SONET/SDH device, enable the slave clock mode on the channel. The SONET/SDH network clock is more precise than the clock provided by the device.

· If the T1 channel is directly connected to a router, make sure the T1 channel uses a different clock mode than the peer end.

network-admin

mdc-admin

Parameters

t3-number: Specifies the number of a T3 channel on the CPOS interface. The value range for this argument is 1 to 3.

detect: Specifies periodical alarm signal detection on the specified T3 channel.

generate: Generates and sends a specific type of alarm signal. The alarm signal is used for line status test.

· ais: Alarm indication signal.

· febe: Far-end block error.

· idle: Idle signal.

· rai: Remote alarm indication.

Usage guidelines

Use this command to check the line state of a T3 channel.

At startup, 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. The alarm state report for the interface is created in real time. You can view the report 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 one type of alarm signal can be sent on a T3 channel at a time. To send another type of signal, you must first remove the previous setting by using the undo t3 alarm generate command. If a RAI signal is present because an LOS, LOF, or AIS alarm is detected, you must first use the undo t3 alarm detect command to remove the signal.

Examples

# Enable alarm signal detection on T3 channel 2 of CPOS 2/2/1.

<Sysname> system-view

Parameters

t3-number: Specifies the number of a T3 channel on the CPOS interface. The value range for this argument is 1 to 3.

pattern: Sets a BERT pattern.

· 2^7: Specifies the pattern length (in bits) as two to the seventh power.

· 2^11: Specifies the pattern length (in bits) as two to the eleventh power.

· 2^15: Specifies the pattern length (in bits) as two to the fifteenth power.

· qrss: Specifies the pattern length (in bits) as two to the twentieth power. In this pattern, the maximum number of consecutive zeros is 14.

time-number: Specifies the duration of a BERT test, in the range of 1 to 1440 minutes.

Usage guidelines

The T3 channel supports the 2^7, 2^11, 2^15, and QRSS BERT patterns defined in ITU O.151, ITU O.153, and ANSI T1.403-1999.

When running a BERT test, the local end sends out a data stream of a pattern, which is looped back at a point of the line to the local end. The local end examines the received data stream for the bit error rate to help determine the line condition. To implement a BERT test, the transmitted data stream must be looped back at a point on the line. For example, enable far-end loopback on the remote interface.

To display the state and result of a BERT test, use the display controller cpos t3 command.

Examples

# Run a 10-minute QRSS BERT test on T3 channel 2 of CPOS 2/2/1.

Parameters

t3-number: Specifies the number of a T3 channel on the CPOS interface. The value range for this argument is 1 to 3.

master: Sets the clock mode to master.

slave: Sets the clock mode to slave.

Usage guidelines

The clock mode settings of T3 channels on a CPOS interface are independent of one another.

Set the clock mode on a T3 channel depending on its connected device.

· If the connected device is a SONET/SDH device, enable the slave clock mode on the channel. The SONET/SDH network clock is more precise than the clock provided by the device.

· If the T3 channel is directly connected to a router, make sure the T3 channel uses a different clock mode than the peer end.

As a best practice, configure the same clock mode of a T3 channel as the global clock mode.

Examples

# Set the clock mode to master on T3 channel 1 of CPOS 2/2/1.

Parameters

t3-number: Specifies the number of a T3 channel on the CPOS interface. The value range for this argument is 1 to 3.

detect: Enables periodical FEAC signal detection on a T3 channel.

generate: Generates and sends a specific type of FEAC signal.

· ds3-los: Specifies the DS3 LOS signal.

· ds3-ais: Specifies the DS3 AIS signal.

· ds3-oof: Specifies the DS3 OOF signal.

· ds3-idle: Specifies the DS3 idle signal.

· ds3-eqptfail: Specifies the DS3 equipment failure signal.

loopback: Sends a specific type of loopback code for activating a specific loopback.

· ds3-line: Specifies far-end line loopback.

· ds3-payload: Specifies payload loopback.

Usage guidelines

FEAC is a channel formed from the third C-bit in the first subframe in C-bit framing. The channel is used for the following purposes:

· Transmits alarm state signals for line test.

· Transmits loopback control code to activate or deactivate far-end loopback during a loopback test.

As defined in ANSI T1.107a, the framing format of FEAC channels is bit oriented protocol (BOP).

At startup, FEAC signal detection is enabled on a T3 interface, but FEAC signal sending is disabled.

Before you configure far-end loopback by using this command, you must disable FEAC signal detection on the local end to prevent loopback deadlock. Loopback deadlock occurs when the local end enables loopback after detecting the loopback code sent back by the far end.

Usage guidelines

When you set a 155 Mbps CPOS interface or channel to concatenated mode, the system automatically creates a 155 Mbps POS channel interface for the channel. The POS channel interface uses the POS interface number [ [/622 Mbps channel number]/155 Mbps channel number]:0 format.

When you execute the using oc-3 or undo using command to change the interface mode from concatenated to channelized, the system automatically deletes the POS channel interface.

Examples

# Configure the 155 Mbps CPOS interface CPOS 2/2/1 to operate in concatenated mode.
