4.1 Introduction
These acceptance tests provide a method of
ensuring the FOCUS is operating in a proper
manner.
4.2 About this Chapter
The instructions in this chapter reference items
that will be selected during testing (e.g., channels,
time slot assignments). These references match
the example screens shown and may differ from
the equipment being tested. The references to
channels and slots are shown for illustration
purposes only. The channels and slots used during
testing should be the number or letter of the
equipment installed in your system.
4.3 Test Equipment
Table 4-1 shows the equipment recommended for
use during acceptance tests.
4.4 Common Equipment
Testing
This section provides instructions for testing the
FOCUS chassis common equipment. This
includes the chassis, Maintenance Module, Power
Supply Module(s), Framer Module, and the trans-
ceiver module(s).
4.4.1 Initial Single Chassis
Acceptance Test
To perform the recommended acceptance test on
a single chassis, complete the following steps:
1. Set up an empty FOCUS chassis.
Install an empty FOCUS chassis in a location
suitable for testing.
2. Connect the power leads.
Connect the ground screw on the Power
supply Interface to an electrical ground (see
Figure 4-1).
Connect power cables to terminals 1 and 2 of
the terminal block (Not polarity sensitive).
3. Connect the (optional) standby power
supply.
If FOCUS has a redundant power supply,
connect the power cables to terminals 3 and 4
of the same terminal block. Connect the
chassis ground.
Prior to setting up any chassis, you should
determine the physical slot locations and the
DS0 time slots you want to use for the various
channel modules in the system.
We also recommend that you start at the
terminal that will be the Master.
NOTE
WE RECOMMEND THAT THE USER OF THIS
EQUIPMENT BECOME THOROUGHLY
