1 Power level is ±10 dBm.

Addressing the Unit

A unique address must be assigned to each control and tributary DSU in your network. You can assign an address within the range of 1 through 255.

NOTE

Do not assign the number 192 as a network address. This number is reserved as a broadcast address.

If a DBM is installed, it requires a separate address which is automatically assigned by the DSU. The address assigned a DBM is the DSU's address, plus 1 (e.g., if the DSU's address is 1, the assigned DBM address will be 2).

NOTE

The numbers 191 and 255 cannot be assigned to a DSU that has a DBM. However, addresses can be assigned in any order; they do not have to be sequential.

It is recommended that only odd- numbered addresses be assigned to DSUs so that even-numbered addresses are reserved for DBMs. If your network does not currently include DBMs, you retain the flexibility to add them later without having to reconfigure your entire network.
