There are subscribers using Pseudo Trunk and a single time slot respectively.
Figure 2.8.1-2
:
Pseudo Trunk Application in Direct mode 2
Pseudo Trunk supports the communication with non-Pseudo Trunk subscriber,
which means that a subscriber with Pseudo Trunk can have normal communication
with a subscriber with a conventional single time slot on the same channel.
As is shown in Figure 2-2, if both Subscriber A and B select Slot 1, they can only
have communication in Slot 1. Both Subscriber C and D select Pseudo Trunk, so
they can have communication in any time slot on the channel. In Pseudo Trunk
mode, the subscriber will take Slot 1 as its default Tx slot. If there are activities on
the channel, Slot 1 must be occupied. Thus, Subscriber A and B will have their
transmissions according to TX Admit settings if they are to establish communication
now.
If they are to call another subscriber in Pseudo Trunk mode, they can only transmit
in Slot 1. If the object subscriber is free, Subscriber A or B will transmit on Slot 1.
Whether to transmit depends on the status of the channel and TX Admit settings of
the transmitter itself. If the called Pseudo Trunk subscriber is busy, it will not
response to the call.
The Pseudo Trunk subscriber can only call Subscriber A and B which are in a single
time slot in Slot 1, otherwise, there will be no response at all. However, the Pseudo
Trunk subscriber is unable to ensure that it must transmit on Slot 1, so you can
consider designating the Tx slot for it. After you designate the Tx slot, the Pseudo
Trunk subscriber can only transmit on that slot but can receive signals and data from
both slots.
Calls between Pseudo Trunk subscribers can take place in any time slot. However, if
the called subscriber is busy, it will not have any response. If the called subscriber is
in transmitting state, the call must be made in its current slot so that the
communication can be set up.
