Phone
The local telephone number (Phone) feature stores the
local DBM’s telephone number if a DBM is installed.
Refer to Table 4-6 to see all available telephone
number characters.
Network Address
The network address (Addr) is the network address of
the local DSU. It is only available from the Local branch.
The DSU’s network address is a number in the range of
1 to 254 if the DSU has a DBM installed. The DBM
automatically acquires an address equal to the DSU’s
plus 1.
Assigning an Address
The Addressing the Unit sections of the installation
chapters, Chapters 2 and 3, provide guidelines for
assigning an address to the DSU based upon its position in
the network – control or tributary. Follow the steps below
to assign a network address to a DSU. Refer to the menu
in Appendix A, if necessary.
