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.
You cannot measure the directed RSSI of both radios in the 
base station at the same time.
Before you begin to measure directed RSSI
Use the Companion Provisioning Record to find the 
following:
the five-digit ID of the base station radio you want to 
measure, by mapping the base station location to the time 
compression multiplex (TCM) port. The first four digits 
indicate the TCM port to which the base station is 
connected. The last digit indicates the number of the radio 
on the base station. For example, the number 0 31 4 2  on the 
base station is connected to TCM port 0314, and 2 is the 
radio number. The number may be printed on a label 
affixed to the lower right corner of the base station 
mounting bracket.
the radio IDs of all other base stations in the same location.
To measure directed RSSI using your portable
1. Repeat steps 1 to 3 of To measure undirected RSSI on page 
84.
2. When the portable displays the base station ID you want to 
measure, move out of the cell boundary range so that hand-
off occurs, and press ´  or e.

3. Press Ò or L.
4. Press °•ªª. 
5. Enter the five-digit ID code for the base station radio you 
want to measure. The portable displays this ID followed by 
the signal strength, for example 03142 - 54. Hand-off 
does not occur as you move between the cell boundaries. 
The link drops when you move out of range.
In this example, the module is 03, the port is 14, and the 
radio is 2. The signal strength measured by the base station 
is -54 dBm.
6. To end the connection, press ´, eor close the flap.
Registering the C3020 (Canada only)

3. On a working telephone, dial the telephone number of the 
registered portable.
If the portable rings, it is functioning properly.
If the portable does not ring, try to register the portable 
again. 
If you do not hear a dial tone, or if the portable does not 
ring, refer to the Troubleshooting section in this guide. 
Deregistering the C3020 (Canada only)
You can deregister the C3020 in two steps:
from the portable
from the administration set (For more information about 
using the Norstar administration set, see the Modular ICS 
System Coordinator Guide.)
For example, you may want to deregister the portable before 
you assign it another number on the same system.
You can also deregister a portable using the administration set. 
You could use this method if the portable was lost or stolen or 
if you wanted to assign it to another system. This procedure 
does not clear registration data from the portable.
If the portable is registered on other systems, it is still available 
on those systems. You deregister one system at a time.
To deregister the C3020
1. Press s, then press m.
2. Press o. The display shows Office n:.

Measuring RSSI for a C3020 (Canada only)
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 portable displays is -44 dBm. 
The weakest RSSI value the portable displays is 
approximately -85 to -95 dBm.
Receive Signal Strength Indicator overrides 
normal display.
You cannot receive calls while measuring 
Receive Signal Strength Indicator.

After registering the portables
When you have completed programming the system, use the 
following checklist to ensure you completed the required 
tasks.
åRegister the portables.
åVerify Portable Credits.
åEnsure that you registered all the required portables.
åVerify that all portables are available for use.
åTest each portable to verify it is operating properly.
åDisable Master Registration when you have finished 
registering the portables.
For the steps involved in operating a Norstar Companion 
portable, see the Companion Portable Telephone User Guide 
that is supplied with the portable. 
When you distribute the portables, tell the users that the 
portables are registered and give them the corresponding 
extension numbers.
Tip - You can register a portable to more than one 
system. You cannot register a portable to more than one 
extension number per system. You cannot register more 
than one portable to one extension number.
If a portable telephone is used in more than one Norstar 
or Companion system, the user must know which 
registration slot number was used to register the portable 
telephone with each system. It is preferable that each 
user register the system they use most in slot 1.
If a portable telephone is lost or broken, you can 
deregister it from the system before replacing it with 
another portable telephone.

Testing
Testing the Companion portable telephones
You must register all portable telephones before testing them. 
For more detail on registering portable telephones, refer to 
Modular ICS Companion System Coordinator Guide and the 
Telephone Registration Instructions.
1. Verify that the portable telephone is ON.
2. Establish a connection to get internal dial tone. If no dial 
tone is present, the portable telephone may not be 
registered. Try to register the portable telephone again.
3. Verify that the portable telephone is using the correct 
registration slot.
4. Verify that the portable telephone can make a call.
5. Verify that the portable telephone has been assigned the 
correct extension number by calling a wired telephone and 
viewing the line number displayed. 
Testing the base stations
1. Verify that the ICS is ON.
2. Verify that re-evaluation is complete.
3. Verify that the base station has been powered up correctly 
by checking that the green light is ON and the red light is 
OFF.
If the red light is flashing, it indicates that one of the 
following problems may exist:
The base station is not connected to the ICS.
The base station is faulty and should be replaced. 
						

							94 / Testing
Modular ICS Companion Installer Guide P0992639 01
A solid red light indicates that both radios on the base 
station are busy, that the ICS is downloading data to the 
base stations, or that one or both radios have not been 
assigned to a cell.
4. Using the directed Received Signal Strength Indication 
(RSSI) feature on a portable telephone verify that you can 
establish a link with every radio on the system while  
within the cell range of the radio.Using another portable, 
establish a second link with the other radio on the same 
base station and check that the red light is ON while both 
radios are active.
Testing the system coverage
Using the undirected Received Signal Strength Indication 
feature on a portable telephone, verify that the base stations are 
handing off calls and serving the coverage area as intended. To 
check valid handoff, move from one cell to another. As you do 
this the radio number shown on the portable telephone display 
changes. 
To test system coverage at critical points, follow these steps:
1. Make a call. Move over the entire coverage area, including 
stairs, elevators and critical points, while maintaining the 
call on the portable. You should maintain good quality 
speech throughout the area you are moving in. 
2. Check that you can receive a call while at these critical 
points. If a significant hole in the coverage area is found 
and the base stations are working properly according to the 
above tests, refer to  Companion Site Planning Guide. You 
may need to redeploy the base stations or add an additional 
cell.
