CDP and LLDP
CDP and LLDP
Device discovery protocols enable directly connected devices to discover information about each other. You
may wish to enable these protocols to allow your network management system to learn about your ATA and
endpoints. Use the Network Setup > Advanced Settings > CDP & LLDP page to specify the settings for
Cisco Discovery Protocol (CDP) and the Link Layer Discovery Protocol (LLDP). When enabled, the ATA
sends messages to a multicast address and listens to the messages sent by other devices using the protocol.

Use the Network Setup > Application pages to support voice service and any servers that you host for public
access.
Quality of Service (QoS) (ATA 192 Only)
Use the Network Setup > Application > QoS page to set the upstream bandwidth to suit your broadband
service. This feature is enabled by default and helps to ensure that voice is prioritized during periods of heavy
network traffic.

Description
Click Always On to enable QoS settings always, or
click On When Phone In Use to enable it only when
there is voice traffic.
Default setting: On When Phone In Use
Enter the maximum available upstream bandwidth
value specified by your Internet Service Provider.
Default setting: 100000 kbps
Important: Do not overstate the upstream bandwidth
that you receive from your service provider. Setting
this value higher than the available service bandwidth
can result in traffic being dropped arbitrarily in the
service provider's network.
