status trunk

Last Updated : Apr 05, 2018 |

Use status trunk to see information about the current status of a single trunk or of all members of a trunk group. You can also use status trunk to locate facilities with which the trunk is communicating.

Note:

If you use status trunk for a trunk that uses a 1d interface, you receive different information with status trunk on the near end of the trunk from status trunk on the far end of the trunk.

  • If you execute status trunk on the near end of the trunk, it correctly indicates whether or not the trunk is in a maintenance state.

  • If you execute status trunk on the far end of the trunk, it never indicates that the trunk is in a maintenance state. This is because the near end is unable to inform the far end of its maintenance state status.

See monitor trunk, which shows the same information as status trunk and updates the screen automatically every minute or on demand.

Syntax

status trunk group# [ /member#]
group#

Status all members of the trunk group.

/member #

Status a specific member of a trunk group.

status trunk field descriptions — page 1

Field

Description

Trunk Group/Member

Group and member numbers of specified trunks.

Port

The location of the port associated with the trunk.

Signaling Group ID

For ISDN trunks, the number of the signaling group to which the trunk group belongs. For other trunk types, the field is blank.

Connected Ports

Locations of ports currently connected to the trunk.

Note:

If a QSIG over SIP trunk call is active on a SIP trunk, the Connected Ports field displays the involved port of the reference trunk. If a QSIG over SIP trunk call is active on a QSIG trunk, the Connected Ports field does not display any ports.

Q-SIP Reference Port

This field works only with the status trunk QSIG-group-number/member-number, where QSIG-group-number is the QSIG trunk group number and member-number is the QSIG trunk group member number. If a QSIG over SIP trunk call is active on a trunk, the system displays the Q-SIP Reference Port field, irrespective of the service state. If the QSIG port is inactive, the Q-SIP Reference port field remains bank.

Note:

If the trunk group is not Q-SIP enabled, the Q-SIP Reference Port field is not displayed.

Service State

One of the following states is displayed: in-service/active, in-service/idle, out-of-service, out-of-service-NE (Near End), out-of-service-FE (Far End), maint-NE/active, maint-FE/active, maint-NE/idle, maint-FE/idle, pending-in-service, pending-maint, or disconnected. NE (Near End) and FE (Far End) refer to which end of the trunk has placed the facility in its current state. Explanations of these service states for each type of trunk are displayed in the maintenance object descriptions in the Maintenance Alarms for Avaya Aura® Communication Manager, Branch Gateways and Servers.

Maintenance Busy

Whether maintenance testing is currently being performed upon the trunk.

CA-TSC State

The status of the call-associated temporary signaling connection, if any. A TSC is a temporary connection set up to pass call information over ISDN-PRI signaling links.

Audio Connection Type

Shows ip-tdm, ip hairpin, ip direct, or ip idle.

Audio Switch Port

Shows a virtual port number (that is, one starting with T). If a trunk is in ip-idle state, the Audio Switch Port field is blank.

Media Encryption

Enter aes for Advanced Encryption Standard encryption, standard used by U.S. government to protect sensitive (unclassified) information. Reduces circuit-switched to IP call capacity by 25%.

Enter aea for Avaya Encryption Algorithm. Not as secure as AES.

Enter none for an unencrypted media stream.
Use status trunk to generate a snapshot jitter and packet loss report for a particular trunk-group member.

In this instance, jitter is the variability in the amount of time (in milliseconds) that packets are received over the network. When jitter increases, the user experiences a noisy connection, delays, and a general loss of quality, making speech unintelligible.

If you issue status trunk for a non-IP station or the connection is hairpinned or shuffled, then the packet loss and jitter size information (page 2) is not displayed. Refer to Administering Network Connectivity on Avaya Aura® Communication Manager for more information.

Field

Description

Average Jitter Last Ten Seconds # - more than 255 ms

The average jitter in received packets from the last ten one-second intervals.

# — more than 255 ms

Packet Loss per Second Last Ten Seconds * - 100% loss

The ten most recent one-second samples of the lost packet information for the requested endpoint.

* — maximum (100%) packet loss per second during the one-second interval. * is displayed when silence suppression is y on the ip-codec-set screen, or when packet loss is 100%.

Out of Order Counter

A count of the number of out-of-order packets detected during the current connection.

SSRC Change for Call

The number of SSRC changes occurring during the current connection.

Last Rx Sequence No.

Last received data packet sequence number.

Last Tx Sequence No.

Last transmitted data packet sequence number.

Worst Case this Call

Jitter — the worst-case, 1-second jitter (ms) experienced during the current connection.

Packet Loss — the worst-case, 1-second packet loss experienced during the current connection.

Average this Call

Jitter — the average jitter for the current connection (the running average of all the 1-second intervals during the connection.

Packet Loss — the average packet loss number for the current connection (running average of all the 1-second intervals experienced during the connection.

Current Buffer Size

The current jitter buffer size.
