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.
The DBM 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 .

Tributary DSU Addressing
Tributary DSU addresses are user-definable. The
control DSU accesses its tributary via an active backup
connection by specifying the tributary's address.
The 6700 or 6800 Series NMS accesses the DSU via its
network address. To access a tributary DSU, the NMS
first addresses the control, then the tributary. An address
issued from the NMS takes the format of control
channel/control DBM network address/tributary network
address. This is called link-level network addressing.
Figure 2-8 shows an example of DSU and DBM
addressing, as well as link-level network addressing.
Refer to
network address.
Verifying Operation and
Testing Connections
Verification testing should be performed after any
installation.
After installing and configuring the circuit (including
control and tributary DSUs, the DDS network, the DBMs
and their dial connections), perform the following series
of tests from the control DSU to verify network operation
(using either the DCP or NMS).
Next, test the tributary DBM for dial tone, and verify
that the DSU can place and receive calls.
