3.2.2 Setting the Default Ring Speed Jumper
In the absence of a management module with port assigning
capability, the TRXMIM can not receive instructions to switch its
ports between rings, so all ports are defaulted to connect to FNB
Ring 1. The Default Ring Speed jumper provides the default ring
speed for FNB ring 1 only.
FNB rings 2, 3, 4 and Auxiliary rings 1, 2
always default to 16 Mb/s.
•
Position the jumper on the proper pins on the TRXMIM, as
illustrated in Figure 3-8, to select either 4 or 16 Mb/s as the
default network ring speed for FNB ring 1.
Note:
The network speed is also selectable via the management module.
Management selections will override hardware jumper selections.
Note:
The ring speed setting is a factor in determining maximum lobe
length. Refer to Chapter 2, Installation Requirements & Specifications for
additional information.
