Frequency Assignment Example

An example configuration is shown in Figure 6-1. In this example The ICRM virtual port card 0 is hardwired to the RIP Connector J205 and virtual port card 1 is hardwired to RIP Connector J206 (see Figure 6-2). Since port card 0 is hardwired to J205 it will be connected to all the TRUs with odd numbered Metro locations (Refer to the Metro RF Frame Figure for the TRU numbering scheme). Hence port card 1, which is hardwired to J206, will be connected to all the TRUs with even numbered Metro locations.

Five datafill tuples are shown in the example figure for:

•a CCH,

•a Digital Locate Receiver (DLR)—serving as the CCH backup in this example,

•an Analog Locate Receiver (ALR)—can be assigned to any TRU, and

•two VCH TRU personalities.

The table in the figure shows the location of the five TRUs with respect to their Metro shelf locations.
