Displaying Running CTP Bundle Configuration, State, and Counters (CTPView)

 

This topic describes how to display the running configuration of your bundle, along with the state and various counters.

Before you begin:

  • Log in to the CTPView software at least at the Net_Admin level.

  • Connect the CTPView server to the CTP device for which you want to change the status of the bundles.

To view information about the bundle:

  1. In the side pane, select Bundle > Runtime Query.
  2. Run your mouse over the MouseOver to Display and Select Bundles to Display bar.
  3. In the table of bundles, select the bundles that you want to view, and click Display Selected Bundles. To select multiple bundles, hold down the CTRL key.

    The configuration of the bundle or bundles appears followed by the runtime state and counters.

    Table 1 describes the fields in the state and counters sections of the display.

    The signaling configuration appears only if you changed the signaling configuration from the default configuration.

Port Speed (kHz)

Displays the port speed in kHz.

Buf Max/Set/Min(ms)

Displays the maximum, running state, and minimum buffer sizes, in terms of milliseconds. The number that you entered varies depending on the interface type and port speed. The set buffer size denotes the buffer size when the circuit enters a running state.

IP Proto/OAM Port

Displays the port configured for IP protocol and OAM applications.

Port(s) in bundle

Displays the interfaces that are part of the configured bundle.

Bndl Config Flags

Displays the current configuration of the bundle:

  • PProtTx—Indicates that the packet protector is set to “Send cloned packets to NET”. The CTP device uses cloned packets that it receives when the IP network drops the original packet. If the device receives both the original and cloned packets, it ignores the cloned packet.

  • PProtRx—Indicates that the packet protector is set to “Expect cloned packets from NET”. The CTP device uses cloned packets that it receives when the IP network drops the original packet. If the device receives both the original and cloned packets, it ignores the cloned packet.

  • PProtTx PProtRx—Indicates that the packet protector is set to “Send & expect cloned packets”. The CTP device sends duplicated packets over the IP network. The CTP device uses cloned packets that it receives when the IP network drops the original packet.

  • PProtTxDel—Indicates that the packet protector is set to “Send delayed cloned packets to NET”. The CTP device sends duplicated packets after the interpacket delay of the circuit.

  • PProtTxDel PProtRx—Indicates that the packet protector is set to “Send delayed & expect cloned packets”. The CTP device sends duplicated packets after the interpacket delay of the circuit. The CTP device uses cloned packets that it receives when the IP network drops the original packet.

  • PProtRxXor—Indicates that the packet protector is set to “Expect cloned XOR packets”. The CTP device uses cloned XOR packets that it receives when the IP network drops the original packet to regenerate the missing packet. If the device receives both the original and cloned XOR packets, it ignores the cloned packet.

  • PProtTxXor PProtRxXor—Indicates that the packet protector is set to “Send & expect cloned XOR packets”. The CTP device sends duplicated XOR packets over the IP network. The CTP device uses cloned XOR packets that it receives to regenerate missing packets when the IP network drops the original packet.

  • PProtTxXor—Indicates that the packet protector is set to “Send cloned XOR packets”. The CTP device sends duplicated XOR packets over the IP network.

Bundle State

Run State

Displays the current state of the bundle:

  • DISABLD—Bundle is disabled.

  • No Sync—The local CTP device is not able to communicate with the remote CTP device.

  • In Sync—The local CTP device is communicating properly with the remote device, but data is not flowing to the interface.

  • Running—The local CTP device is communicating and is synchronized with the remote CTP device. The circuit is established between the bundles.

  • Eval—The bundle is in the transition state between No Sync and In Sync.

  • TooSlow—Encountered when the bundle is configured for all clocking to be done by the external transmit timer (TT) clock. The error occurs when either no clock is provided by the external device or the rate is different from the configured rate.

  • TooFast—Encountered when the bundle is configured for all clocking to be done by the external TT clock. The error occurs when either no clock is provided by the external device or the rate is different from the configured rate.

  • TtFAIL—The TT differs from the configured value by more than 1/16.

  • MisCfg—A misconfiguration of the bundles between the local and remote devices prevents the circuit from being brought up. For example, incorrectly configured IP addresses and mismatched speeds.

  • CfgFail—The configuration of the bundle cannot be supported. If you encounter this error, delete the bundle and create a new bundle.

  • AutoWait—The bundle is waiting for the TT to stabilize.

Port Runtime Flags

Displays the current configuration of BERTs and serial loops.

  • Inactive—No activity is detected on the serial input. The activity detector checks the serial input line every 500 milliseconds for any transitions on the line. Port Run Time flag of the serial CTP bundle shows the status as Inactive if no activity is detected on the serial input line. This flag is displayed only when the serial input line is inactive, which is an abnormal condition. No such flag is displayed if the serial input line is active.

    This flag applies only to a serial port that has a T1E1 DCARD installed and is in use. It does not apply to ports on a T1E1 card.

  • BertFrmNet—Used to receive the BERT from the network

  • BertFromIf—Used to receive the BERT from the interface

  • BertToNet—Transmit BERT for this port is active and is sending the network bound data, thereby interrupting the normal data path from the interface.

  • BertToIf—Transmit BERT for this port is active and is sending the interface bound data, thereby interrupting the normal data path from the IP network.

  • LoopToNet—Used to loop back the BERT to the network

  • LoopToIf—Used to loop back the BERT to interface

IRIG-B Run Flags

Displays the current status of the IRIG-B runtime

  • TxIpSync—Transmit mode is in sync with the remote CTP device.

  • TxSyncLost—Transmit mode is not in sync with the remote CTP device.

  • RxIpSync—Receive mode is in sync with the remote CTP device.

  • RxSyncLost—Receive mode is not in sync with the remote CTP device.

T1E1 flags

Appears for bundles on T1/E1 interfaces.

  • LOS—Loss of signal. This could mean that the cable is not attached. When LOS is detected, the CTP device puts the bundle into a loop so that the TX and RX clock are looped to each other.

  • LOF—Loss of frame.

  • AIS—Alarm indication signal.

  • RAI—Remote alarm indication (yellow alarm).

  • LOF_NB—Fractional T1 only. FPGA framer loss of frame network bound.

  • LOF_IB – Fractional T1 only. FPGA framer loss of frame interface bound.

TT (Ext Clock)

Displays the current speed of the transmit timing (TT) clock.

The TT measurement is displayed only for a CTP bundle or a SAToP bundle that is attached to a T1E1 port on a T1E1 Daughter Card or a CTP bundle attached to a serial port with clock configuration set to Configured with TT, All Clocked by TT, Adaptive Rate, w/ User Clk (TT), or Autobaud Rate, w/ User Clk (TT).

RT (Ext Clock)

Displays the current speed of the receive timing (RT) clock.

Appears if the bundle is configured as the DTE, and clocking is set to DTE, All Clocked by Ext Clk (ST/RT) .

Adaptive State

For bundles that are configured as the adaptive end for adaptive clocking, displays the current state of the adaptive clock:

  • Maintain (20 us)

  • Maintain (968 us)

  • N/A (Port Not RUNNING)

Adap Recovered Freq

For bundles that are configured as the adaptive end for adaptive clocking, displays the frequency currently being recovered from the master end.

Input Signals

Displays the running configuration of input signals.

Output Signals

Displays the running configuration of output signals.

Checked out PPS

Displays packets per second (PPS) for the current bundle, for all running bundles on the CTP device, and the maximum PPS for the CTP device.

Note: For CESoPSN bundle, this field is available only in CTPOS release 7.0 and later.

Port Config

Port Desc

Displays the description of the port.

Interface type

Displays the type of interface.

The type of interface that you select affects the default packet size and buffer sizes for the bundle.

Port Config Flags

Displays the current configuration of the port:

  • T1LoSCheck—Denotes that LOS detection is specified on a T1 port connected to a CTP bundle or a SAToP bundle

  • E1LoSCheck—Denotes that LOS detection is specified on a E1 port connected to a CTP bundle or a SAToP bundle

  • NoRdReclk flag—Signifies that the redundancy receiving (RX) clock is disabled. The NoRdReclk flag is also displayed because this flag is default enabled for a T1/E1 port, whereas it is usually not enabled for a serial port.

When you run the bundle query for CTP bundles and SAToP bundles, the T1E1 port type displays port configuration flags that are relevant to a T1E1 port.

Framing type

Displays the framing type for T1 interfaces.

  • ESF

  • D4

Redundancy Config

Displays the configured redundancy mode.

  • Disable—Y-cable redundancy is not enabled on this port.

  • eXclusive OR (XOR)—Redundancy is enabled. In this mode the Y cable is active only if the port is in RUNNING state and the serial port on the Y-cable link is not in RUNNING state. If both bundles are RUNNING, the Y cable remains inactive on both the ports.

  • ReVeRT (RVRT)—When you select this mode, a primary and a secondary path is enabled. The primary path drives the cable when its bundle is in RUNNING state, independent of the state of the secondary path. The secondary path is activated when the primary path is offline. Whenever the primary path comes back online, the path is switched back to the primary path.

  • NOnReVert (NORV)—When you select this mode, the circuit is not switched back to primary when the primary path comes back online after switching to secondary path. The circuit is switched to the primary path only when the secondary path fails.

  • Signal (SIG)—The primary path is activated only if the secondary CTS output is inactive. When CTS is active, secondary drives cable.

Primary/Secondary

Specifies whether it is a primary and a backup bundle. When the software link is enabled and link partners are specified, the software verifies that there is a matched primary and backup pair.

Pri/Sec Link Type

Specifies the link types for primary and back up bundle.

  • H/W link—When enabled, the Y-cable redundancy is supported only on serial ports, and the link between ports is a hardware signaling connection over a special Y cable that uses the output to cable(TM) and the input from cable(RL) to communicate redundancy state between port pairs, by using keepalive pulses. Its operation is similar to the default operation of the redundancy feature in CTPOS Release 6.5 and earlier.

  • S/W link—Allows Y-cable port pairs to maintain contact with each other by means of OAM packets instead of using a hardware signaling path. The software link has the following advantages:

    • The software link does not require a special signaling hardware, which means that Y-cable redundancy is supported on T1E1 ports as well as serial ports with a special Y cable. Serial ports can get TM/RL signals for user applications.

    • Software or OAM link packets can check link partners and identify configuration errors. They can also differentiate between dead and alive states.

IP Address

Specifies an IP address for the other port of the redundant primary and backup pair.

Line Buildout

Displays the line buildout for T1 interfaces.

  • 0) ~133 ft

  • 1) ~266 ft

  • 2) ~399 ft

  • 3) ~533 ft

  • 4) ~655 ft

  • 5) -7.5dB CSU

  • 6) -15dB CSU

  • 7) -22.5dB CSU

Clock Source

Displays the type of clocking for the port.

  • CTP is Clock Source—The PBX either returns the clock received from the CTP or it returns a clock that is traceable to the same source as the CTP node clock reference. You typically use this configuration when you configure the CTP device with a clock reference input.

  • CTP is Loop Timed—The PBX provides the clock and the CTP returns the same clock to the PBX. You typically use this configuration when the PBX has the more accurate clock source. You can configure the far end of the circuit with adaptive clocking to recover this clock if necessary.

  • CTP is Clock Source (Adaptive End)—The PBX returns the clock received from the CTP, and the CTP uses the adaptive recovered clock. You typically use this configuration when the CTP does not have a reference input and the PBX typically requires clock from the distant PBX.

    On CTP150 devices, If you set clocking to CTP is Clock Source (Adaptive End), the first bundle activated on the interface is assigned as the adaptive master bundle on which the transmit clock is adjusted. This bundle is also the last bundle to be deactivated on the interface.

Port Speed (kHz)

Displays the port speed in kHz.

Node Sync Info State

Note: This section is displayed only if the cmd bndl X qry dbg_cstm1 option is selected from the Runtime Query Selection list under the GUI Settings pane.

PLL Lock/Ref

Indicates whether the phase lock loop (PLL) is currently locked to a valid reference (YES) or whether no reference is available (NO).

PLL Monitor Runtime

Indicates the time (in seconds) that the PLL has been monitored since the last restart of the CTP or reconfiguration of the CTP reference.

PLL Monitor Loss

Indicates the number of seconds during the PLL monitor runtime that the PLL has not been locked.

Bundle Counters

I/F bound packets

Packets received from the IP network destined for the bundle.

NET bound packets

Packets created by the bundle and sent to the IP network.

Late pkts

Packets that were delivered to the CTP device, but arrived too late to be processed. Significant numbers of late packets indicate that the size of the buffer needs to be increased.

Missing pkts

Packets that were not delivered to the CTP in time to process out the serial interface because they were either late or dropped by the IP network.

Each time a packet is missed, the data fill pattern specified in the advanced port options is substituted for data in the missed packet. The substitution maintains the bit count integrity of the data sent to the DTE or encryptor, but results in what appears to be a burst of errors with a duration equal to the size of the packet.

Buffer restarts

Number of times the buffer was restarted.

Buffer underflows

Number of times that the average buffer state was less than the minimum buffer setting.

Buffer overflows

Number of times that the buffer state exceeded the maximum buffer setting.

Buffer starves

Indicates an exceeded threshold. The CTP device is designed to tolerate strings of consecutive missing packets without the loss of bit count integrity. The number of packets is configurable; the default is five. Exceeding this threshold is called a starvation, and a counter is incremented each time this event occurs.

Buffer max samples

Largest buffer sample observed.

Buff Max/Avg/Min

Maximum, average, and minimum buffer sizes observed.

Buff Last Minute

Maximum, average, and minimum buffer sizes observed in the last minute.

BERT running sec

Number of seconds the current update has been running.

BERT sync sec

Number of seconds that the local CTP device has been in sync with the remote CTP device.

BERT error sec

Number of seconds during which there were errors.

BERT in sync

Shows whether the CTP device is currently in sync with the remote CTP device

Last counter clear

Indicates the last time that the system counters were reset.

This feature is supported on CTPOS release 6.6R3 and later for CESoPSN bundles created on CTP2000 series.
