PassPort Trunking Controller Board (PTCB)

PassPort is an enhanced trunking protocol developed by Trident Microsystems that supports
wide-area dispatch networking. A network is formed by linking several trunked sites together to form
a single system. This offers users an extended communication coverage area. Additionally, users
with PassPort can seamlessly roam among all sites within the network. Seamless roaming means
that the radio user does not have to manually change the position on the radio when roaming from
site to site.

For models which feature PassPort Trunking operation, the PassPort Trunking Controller Board
(PTCB) is added to the top cover of the radio. This board also provides advanced voice storage
features. Refer to Figure 2-1 for connector and signal routing from and to the radio and PTCB.
