Figure 7-50. PARS Normal Operation Mode using four IAD Nodes
A four node configuration operating in PARS mode is illustrated in Figure 7-50. In this
configuration one user port per node is used for the purpose of illustration. In node one the
transmit of all 24 time slots of W1-1 are cross-connected to the receive of all 24 time slots of
W1-2. The receive of 23 time slots of W1-1 are cross-connected to the transmit of 23 time slots
of W1-2. The HSU transmit is connected to the receive of one of the W1-1 time slot and its
receive is connected to the transmit of the corresponding time slot of W1-2. Similar
connections are made in the rest of the nodes.
