Installation recommendations include the following:

Each node must have at least one central office trunk. Emergency calls should be pro-

grammed to use the local trunk.

If the Voice Processing Unit is shared by multiple nodes, all of the nodes should have

of hops through other nodes. This will have significant impact on the network layout.

The network does not allow one node to use another node's resources (DSP resources,
