Use DHCP Server Check Box
The Use DHCP Server check box, if selected, indicates DHCP (Dynamic Host Configuration Protocol) is used. If selected,
DHCP allows the IP-223 to acquire all of the information from the network bypassing any manual entry.
NOTE: Telex does not recommend operating with DHCP enabled. Operating with DHCP enabled may cause the base IP
Address to change unexpectedly making changes to the software setup more difficult. If employing 5/6-tone
selective calling and messaging, DHCP must not be used.
Unit IP Address Field
The Unit IP Address field is used to enter a unique base IP Address for the IP-223. The web browser configuration uses the IP
Address to identify the IP-223 for such operations as set up, software upgrades, and communications in some operating
modes.
Subnet Mask Field
The Subnet Mask field is used to enter the Subnet Mask Address. The Subnet Mask is used to distinguish local addresses
from addresses requiring the use of a gateway to reach other networks. Contact your network administrator to obtain the
proper value for this field.
Gateway Address Field
The Gateway Address field is used to enter the Gateway Address. The Gateway Address is the IP Address for the node used
to reach other networks. Contact your network administrator to obtain the proper value for this field.
DNS Number 1–3 Fields
The DNS (Domain Name Server) Number 1–3 fields are currently not supported by the IP-223.
Packet Delay before Playback Field
The Packet Delay before Playback field is used to enter a delay of audio packets before they are played. The IP-223 utilizes
a 20ms UDP/IP (User Datagram Protocol/Internet Protocol) packet to encode audio. Some buffering of these packets must
occur before playback to help absorb network delays, jitter, and lost packets.
The range for this field is 4 to 29.
The typical entry for this field is 6, which translates to a delay of 120ms before playback (each packet is 20ms of audio).
Larger values may be required for complicated networks, and smaller values for less complicated networks.
QOS: Precedence Bits Field
The QOS: (Quality of Services) Precedence Bits field is used to set the priority level of network traffic.
The range for this field is 0 to 7.
Typically this value is set to 0 for normal traffic and 5 for voice traffic.
