The following section describes the procedures involved in
registering Companion C3060 portable telephones. To register
each portable with the Norstar system, you must do two things:
•Register the portables by entering the Registration
password on each one.
•Verify that the portable functions correctly.
C3060 Icons
The following table identifies the C3060 portable telephone
icons:
b. Dial the number of a working telephone. The telephone
must ring to confirm the registrati on.
3. Receive a call.
a. If the portable has the same extension number as a desk
telephone, make sure the desk telephone is idle and Call
Forward is not active.
b. On another working telephone, dial the telephone
number of the registered portable. The portable must
ring to confirm the registration.
If you do not hear dial tone, or if the portable does not ring,
refer to “Troubleshooting” in Meridian Companion Installation and Maintenance Guide. If you continue to
experience difficulty registering the portable, contact your
distributor.
Deregistering the C3060
You can deregister the C3060 in several ways:
•from the portable
•from the Administration Terminal (refer to Meridian Companion Administration Terminal Operations Guide)
•from Companion Manager (refer to C ompanion Manager Installation and Operations Guide)
Deregistering the C3060 from the portable clears registration
information stored in the portable and the system. For
example, you may want to deregister the portable before you
assign it to another WTN on the same system.
Deregistering the C3060 from the Administration Terminal or
from Companion Manager does not clear registration data
from the portable. (You could use this method if the portable
were lost or stolen or if you wanted to assign it to another
system.)
The Receive Signal Strength Indicator (RSSI) is a
measurement of the signal strength the Base Station receives
from the portable. The Base Station controls the power
transmitting mode of the portable. When the Base Station
receives a weak signal, it instructs the portable to transmit in
high-power. When the Base Station receives a strong signal, it
instructs the portable to transmit in low-power. The strongest
RSSI value the display shows is -35 dBm. The weakest RSSI
value the display shows is approximately -94 to -100 dBm.
Measuring undirected RSSI
You can measure the signal strength between a portable and a
system-selected Base Station using undirected RSSI.
1. Press m.
The display show s
MENU.
2. Press , or . until the display shows Feature request
.
3. Press SELCT . The display shows A- .
4. Press * 8 9 8. The display shows the cell
number, the radio ID of the Base Station to which the
portable is linked, the power mode (high or low), followed
by the signal strength and the channel. For example, 8 15112 H 67 29.
You can also press ⁄ to view the information in “standard”
display mode. This mode displays the radio ID of the Base
Station to which the portable is linked, followed by the
signal strength and power mode. For example, 15112 - 67 H . You can revert back to the initial display mode by
pressing ƒ.
Hand-off occurs normally between the cells.
Note: In this example, the cell is 8, the card is 15, the port is
11, the radio is 2, and the channel is 29. The signal
strength measured by the Base Station is -67 dBm, and
the H indicates the portable is transmitting in highpower mode (an L indicates low-power mode).
5. To end the connection, press k.
Measuring directed RSSI
You may want to measure the RSSI between a portable and a
specific Base Station radio. For example, you may suspect that
one of the two radios in a Base Station is not working properly.
You can also use directed RSSI to prevent hand-off while you
find a cell edge. To measure the RSSI of a specific radio, you
must be in range of two Base Stations—the one you want to
measure and another Base Station.

Note: You cannot measure the directed RSSI of both radios in
the Base Station at the same time.
Before you measure directed RSSI, use Meridian Companion Programming and Provisioning Record to find and note the
following:
