Paradyne 3615, 3616 manual Addressing the Unit

COMSPHERE DualFlow Data Service Units

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 3-5 shows an example of DSU and DBM addressing, as well as link-level network addressing.

Refer to Chapter 4 to learn how to set the DSU's network address.
