A technician is trying to pair a Touch 8 with a Cisco TelePresence SX20 endpoint, but the codec is not automatically listed in the touch panel. What are two possible reasons for this behavior? (Choose two.)

Question

Accepted Answer

B. The codec and the Touch 8 are on separate subnets. The Touch 8 uses multicast-based auto-discovery to find codecs on the network; multicast traffic does not cross subnet boundaries by default, so a codec on a different subnet will not appear in the Touch panel device list. C. Pairing visibility mode is not active on the codec. The codec must have pairing visibility mode activated in its settings to broadcast its presence for auto-discovery; if this mode is disabled, the Touch 8 cannot detect the codec automatically.

Answer

A. The codec firmware version is below version TC 6.1. While Touch 8 requires a minimum firmware version, the relevant threshold is TC 7.x or later, not TC 6.1; TC 6.1 is not the boundary version for Touch 8 compatibility.

Answer

D. The codec is not compatible with a Touch 8 device. The Cisco TelePresence SX20 is a supported and compatible codec for use with the Touch 8 control panel.

Answer

E. The Touch 8 is connected via the second Ethernet port on the codec. The Touch 8 connects via the dedicated touch panel port or the primary LAN port on the codec, and connection via the second Ethernet port is not a documented reason for auto-discovery failure.
