TDM Channel Configuration
Routing Time Division Multiplex Timeslots
PPC/PMC-8260/DS1
The Time Division Multiplex (TDM) channels of the PowerQUICC II are con-
nected to the framers and the H.110/SCbus via the T8105 timeslot interchanger.
The schematic figure shows these connections of the H.110-F and SC-F variants.
Figure 18: Connection of TDM Channels
The timeslot interchanger has 16 local TDM channels, each supporting
32 timeslots. The framers support 24 timeslots if configured for T1/J1 or
32 timeslots if configured for E1. To be able to build your specific network each of
the mentioned timeslots can be switched between:
•
Local TDM channels (between the PowerQUICC II and the framers)
•
H.110/SCbus TDM channels
•
Local TDM channels and H.110/SCbus TDM channels
This means that any local timeslot can be switched from the PowerQUICC II or one
of the framers to any timeslot on the H.110/SCbus or vice versa. In the same way,
any local timeslot can be switched between the framers or between the framers and
the PowerQUICC II. This can be seen in the following figure.
