Configuration / Operation 217
Figure 12-9 shows the entry for unit 002’s frame relay port that connects to the
foreign device. The DLCI here does not match any of the others. Remember,
DLCIs only exist between devices, not all the way through a connection or PVC.
Option A - Transparent Channel On Public Network
When this option is set for a specific DLCI, it causes the MultiPro unit to relay
frames exactly as they are received (Figure 12-10). The only field the MultiPro unit
may change is the actual DLCI number if the incoming DLCI is different from the
outgoing DLCI. This does not effect the data or transparent nature of connection.
The difference with a public network is that usually only one DLCI is available
and must transport both transparent data and other traffic types. In this case the
transparent data is sent on an individual LCN as if it were a station.
