Chapter 3 Operation
3-4
In the case of a data type plug-in card, the data will be assigned to as many DS0 time slots as the data rate
requires. These DS0 time slots must be assigned to the same port, though not necessarily contiguous DS0
time slots of that port.
NOTE: The payloads from an original source must be kept in a group in their original order when they are
mapped or the data will not arrive in the correct order.
The following diagram shows data payloads from remote units being mapped to a Loop-V4100 which will
map them on to another part of the network. The payloads are kept grouped together with their individual
components in their original order.
In the following diagram the DTE payload information is not kept in a group. This is unacceptable. The DTU
mapping is fine because those payload components are kept in their original group.
