# IP/XNET Trunk Groups

## Purpose

The IP/XNET Trunk Groups form is used to gather trunks into groups for the Automatic Route Selection forms.

NOTE: The number of XNET trunk groups is based on the Maximum Number of Elements per cluster (assigned in the License and Option Selection form). A network cluster of 30 or 60 supports 81 XNET trunk groups. A network cluster of 250 or greater elements supports up to 999 IP/XNET trunk groups.

Use this form when performing the following tasks:

- IP Networking Programming

- XNET Programming

## Field Descriptions

Parameter | Description | Default Value
XNET Trunk Group Number | System-generated, protected field. Identifies the XNET trunk group number. |
PBX Number | Enter the unique number of the system to which you want to make XNET calls. The unique system number must be created in the ICP/PBX Networking form before it can be entered in this form. | Blank
Local Profile Number | Enter the number used to identify each profile, which corresponds to the Local Profile Number field in the IP/XNET Trunk Profiles form. The Local Profile Number must be created in the IP/XNET Trunk Profiles form before it can be used in this form. | Blank
Maximum Network Hops | Enter a value between 1 and 26 to specify the maximum number of network hops (between systems) that an XNET call can take. | 26
Network Signaling Type | Select a value of "ISDN" (PRI B-channel) or "IP" to indicate the signaling for this XNET trunk group. | IP
Voice Medium Type | Select a value of "TDM" or "IP" to identify the type of voice signaling used. | IP
Number of Trunks | Enter the number of concurrent outgoing XNET calls that can have this profile between this system and the indicated Remote system. You can enter a value up to the maximum number of IP trunks on the system (2000). Higher values are designed for, but restricted to, IP trunk groups that use IP for network signaling and voice medium type. Real and virtual calls can be active concurrently between the two systems. This value should not exceed the maximum number of calls defined in the ICP/PBX Networking form (if it does, the value in the XNET ICP/PBX Networking form is used). | 200
Comments | Enter information (up to 16 characters) to identify the use of this XNET trunk group. | Blank
