Network Elements

Purpose:

The Network Elements form manages all elements within a network. Use this form to

view, define, and manage the basic attributes of network elements, such as name, IP address, type, data-sharing status, and zones.
specify the elements that you want to start sharing system data with and set the scope All Network Elements, All Cluster Members, All 3300 ICPs, Network Group Members, Admin Group Members, Resilient Pair, Member Hosts, Hospitality Gateway and Guest Room Host, Hospitality Gateway and Suite Host, or None. of the sharing.
specify elements that you want to synchronize data with and select the forms and data records that you want to synchronize.
sort, modify, and delete network elements belonging to a data-sharing network or cluster
create network elements for SIP trunks by creating a network element for the local switch, a network element for each SIP peer, gateway or Service provider, and creating a network element for the Outbound Proxy, if one exists in the network (see Program SIP Trunks).

Use this form when performing the following tasks:

Conditions

The local network element record is automatically created during system software installation, and cannot be deleted.
A cluster must be created (defined) in the Cluster Elements form before you can assign elements to it. See Voice Clustering Programming Overview for instructions on how to set up clusters.

Field Descriptions

Parameter

Description

Default Value

Name

Enter a unique name of up to nine characters for the network element. Start the name with an upper case letter; enter all other letters in lower case. Digits are allowed but not spaces or non-alpha characters. This naming convention must be followed if Enterprise Manager will be used to manage the network element.

This name displays in read-only format in the system name field in the local element's System Options form.

Note: The name must be identical to the element name entered in Enterprise Manager. Otherwise, attempts by Enterprise Manager to program resilient data on the secondary controller will fail.
Note: The name must also be identical to the name of the networked voice mail server (if programmed) in the VM Network Servers form; otherwise, you will be unable to add or edit extension mailboxes.

Blank

Type

Defines the type of network element (for example, 3300 ICP). Select the network element type from the drop-down list. The type selected determines the specific information that displayed to be filled in.

Note: Before you can enable data sharing with an element, you must set the element type to "3300 ICP".

3300 ICP

FQDN or IP address

Defines the Fully Qualified Domain Name (FQDN) or IP Address of the Network Element. This field is disabled for the local network element.

Typically, you should enter an IP Address. However, if the system will support SIP devices and if the SIP Service Provider uses the Fully Qualified Domain Name (FQDN) instead of an IP Address to communicate with the system, enter the FQDN.

Notes:
To use the System Data Synchronization (SDS) feature with this element, this field must be must be programmed with an IP Address. If a FQDN is entered in this field, SDS is not supported.

If you need to change the LOCAL system's IP address, you should modify the address through the System IP Properties form at the remote 3300 system.

Blank

Data-sharing

System-generated field. Identifies the current data-sharing state of each network element listed.

This field displays each network element's data-sharing status and scope as follows:

----	indicates that the field is not applicable to local element
NO	indicates that the element is not sharing with local element in any scope
YES*	indicates that the element is a member of a cluster but is sharing only at the network level (that is, sharing has not been initiated at the cluster level).
YES	indicates that the element is sharing data within either a network or cluster scope, or both.

True/False

Local

Displays "True" if the selected network element is local. Displays "False" if the selected network element is not the local element. This field should only display "True" for the element you are logged in to.

Note: The local PBX for each network element is assigned in the ICP/PBX Networking form.

Version

If the local element is sharing data with a remote element, this field displays the remote element's software version.

The version number is cleared if you

disable SDS on either element, or
disable data sharing between the elements.

Blank

Zone

The zone specified for the IP voice media stream originating or terminating at the selected ICP. It defaults to 1. The zone range is 1-250.

Note: If sharing with a pre-8.0 switch, the default Zone value of 1 cannot be changed for the pre-8.0 switch.
Note: Do not use zones IDs greater than 128 if sharing between Release 8.0 and older releases; however in clusters where all elements are Release 8.0, it is allowed.

SIP Peer

Click the check box to make the network element a SIP Peer and then fill in the related SIP Peer Specific fields that display.

Note: The Zone for the SIP Peer is assigned in this form.

Blank

3300/SX2000 Properties

Note: Field header grouping identifies properties that apply only to 3300 ICP or SX-2000 systems.

Member of Cluster

Enabled if the selected network element is a member of the cluster, and indicates the cluster name. This field is not enabled if the selected network element is not a member of the cluster.

Blank

PBX Number/Cluster Element ID (CEID)

Displays the element's PBX or CEID index number if the element is clustered. Valid numeric entries are from 1 to 999. The CEID index number corresponds to a CEID digit string that is programmed in the Cluster Elements form.

Enabled only if the network element is clustered.

Blank

Primary Node ID (PNI)

The Primary Node ID is used to route calls to other non-cluster elements in the network. Enter a value of up to seven digits in length. This value also appears in the ARS Node Identities form in the primary Directory Number (DN) field.

Only the local network element PNI is manageable from this field, and only if the local network element does not belong to a cluster.

A PNI cannot appear as a directory number or as an ARS string on any of the systems in the network. Use the "Locate Number" maintenance command to determine if the PNI is a number that is already used on any of the other elements in the network.

Blank

Outbound Proxy Specific

Note: In the fields below, the default is blank. The default in blank in cases where DNS is used to determine the transport and port parameters. Otherwise, you should set the appropriate values. The common SIP UDP/TCP port is 5060, and the common SIP TLS port is 5061.

Transport

The list of transport parameters used in the SIP URI: UDP/TCP/TLS.

Default (UDP)

Port

Enter the port number of the Service Provider or the gateway.

Blank

SIP Peer Specific

SIP Peer Transport

The list of transport parameters used in the SIP URI: UDP/TCP/TLS. Use TLS if you require encryption between 3300 ICP devices in the same network. TLS is not supported across firewalls.

Default ( UDP)

SIP Peer Port

Enter the port number of the SIP Peer.

External SIP Proxy FQDN or IP Address

Enter the IP address or the Fully Qualified Domain Name (FQDN) of the SIP proxy server of the peer network. Do not fill in this field if an External SIP Proxy is not in use.

Blank

External SIP Proxy Transport

The list of transport parameters used in the SIP URI: UDP/TCP/TLS.

Default (UDP)

External SIP Proxy Port

Enter the port number of the proxy.

SIP Registrar FQDN or IP
Address

Enter the IP address or the Fully Qualified Domain Name (FQDN) of the SIP registrar of the peer network. Do not fill in this field if an External SIP Proxy is not in use.

Blank

SIP Registrar Transport

The list of transport parameters used in the SIP URI: UDP/TCP/TLS.

Default (UDP)

SIP Registrar Port

Enter the port number of the SIP Peer.

SIP Peer Status

Defines SIP peer status, which can be Auto-Detect/Normal, Disabled, or Always Active.
Auto-Detect/Normal periodically sends OPTIONS messages to test to see if the link to the remote SIP Peer is alive. When the link is detected to have gone away the SIP Module marks the link out-of-service and periodically sends OPTIONS messages to restore service.

Setting the Always Active option causes the SIP Module to assume that the link is available unless you choose another option.

Use the Disabled option to temporarily disable a trunk connection
