Unicast bundle: CobraNet bundles 256~65,279 are unicast bundles. (However since the

ACU16-C/NHB32-C support only bundle numbers 0~16,383, they can only use unicast

bundles 256~16,383.) In other words, these are transmitted only if the two devices are set

to transmit and receive that speciﬁc bundle. Unicast bundles only allow point-to-point con-

nections and as such are far more bandwidth efﬁcient than multicast bundles. This efﬁ-

ciency means that CobraNet can happily coexist with networked computers, printers, etc.,

on a switched 100Base-T Ethernet network. However, non-CobraNet devices may unpre-

dictably demand a lot of network bandwidth, which may affect CobraNet performance and

even cause audio dropouts, pops, or clicks. A dedicated CobraNet network is strongly rec-

ommended for mission critical applications. Unicast bundles can only be used on switched

networks. Unicast bundles can be conﬁgured to work like multicast bundles, but that’s

beyond the scope of this glossary. Contrast with Multicast Bundle.

UTP (Unshielded Twisted Pair): A cable consisting of two unshielded conductors that

are twisted together.

WAN (Wide Area Network): A network that covers a wide area, typically made up of

two or more LANs. CobraNet is not a WAN technology. See also LAN.
