As the illustration shows, the ports are numbered
from left to right. The left-most port is port number 1
and the last one on the right is number 4.
Ports also have logical numbers, used by the
Routing Table, which are different from their physical
numbers. Logical port numbering is where the FXS
and FXO ports are counted separately, and the
count starts from zero instead of one (See Section
4.5, Routing Table, in this Guide).
1.6 Installing the Max 410/420/430 Unit
Proceed with installation as follows:
1. Install the unit in a well-ventilated area. If it is to
be placed on a surface rather than in a rack, be
sure that all four rubber feet are in place to allow
for proper air circulation. Do not place objects in
excess of 20 pounds on top of the unit.
Please refer to the Max 410/420/430
Hardware Installation Guide and
observe the safety precautions
listed.
2. Connect an analog telephone to any one of the
FXS ports. (Max-420)
