CM-16

Mobility solution for Meridian 1 PBX environments

Frequently asked questions

  Will the CM-16 Cordless work on my home phone line?


No. The CM-16 is designed to work on a Nortel M1 PBX or the Nortel SL100 System. It emulates the key and display functions of a M2616 telephone set.

  My Meridian 2616 has 16 Feature Keys. How many does the CM-16 have?


There are 14 Meridian features available through the CM-16. The features list can be accessed through the feature F key of the CM-16.

  What do the 3 LEDs on the base unit indicate?


The left LED indicates Power is applied to the base. It should always be ON.
The center LED indicates an active M1 port is connected with the correct polarity. It should blink at a 2Hz rate continuously.
The right LED turns ON steady to indicate the handset is In Use and blinks briefly when handset and base pairing is taking place.

  I’m having trouble with the installation of the CM-16. Is there a more detailed installation document available?


Yes. Please visit the CM-16 Download page for the latest revision of the Installation Instructions

  How does handset pairing work?


Pairing assigns one handset to one base. The pairing function is used when a handset or base must be exchanged during maintenance. The product ships with the handset and base already paired, so pairing is not needed until either of the two components is replaced.

For pairing to work, a properly operating M1 line must be connected to the base and the base must be receiving power from its power adapter over the 6-conductor cord (supplied).

To initiate pairing, first press the button on the back of the base. Using the handset, locate the pairing option and select it. Allow 30 seconds for the pairing process to complete and a message to appear on the handset display.

  Is there a limit to the number of CM-16 cordless phones that are supported in a single building/warehouse?


Not that we’re aware of. But placing a number of radio products operating in the same frequency band in close proximity is bound to introduce noise that can degrade transmission and data rates.

We recommend 12 ft spacing between CM-16 bases, handsets and other 2.4GHz radio products. The CM-16 radio uses frequency hopping in the 2.40-2.46GHz band to avoid interference with other CM-16 as well as WiFi products. So with sufficient spacing you should have no problem operating several CM-16 products in the same area even with a 802.11b/g wireless network in the vicinity.

   Will this phone work in a factory or warehouse environment? What is the range?


Yes, the phone should work in a factory or warehouse environment. With a centrally located and elevated base to assure line of sight with the handset, a user could move up to 300 ft maximum in any direction from the base (approx 300,000 sq ft. coverage). Realistically, you can expect your range to be less than this ideal coverage due to signal degradation within the building structure and other radio products operating in the 2.4GHz range.

  Are there range extenders available that can be placed in areas of low reception?


No. Not at this time.

  How many lines does the CM-16 support?


The CM-16 is designed to work as a 2616 set. You can literally unplug the 2616 from the wall and plug in the CM-16 and start using it. All assigned buttons on the 2616 set are accessible on the CM-16 handset.

  Can CM-16 calls be intercepted or monitored?


CM-16 calls can not be intercepted by the average user employing standard consumer retail equipment such as scanners. The radio channel uses digital speech coding and a frequency hopping scheme with an interference mitigation algorithm which are not publicly disclosed. It would take considerable resources, time and money to compromise this scheme.

  What are the talk and standby durations for the CM-16 battery?


4-5 hour talk, 3-5 day standby

  I am standing next to the base of the telephone, why do I get Out of Range displayed?

  Do I need to install the base using the supplied power adapter and line cord?


Yes. The power adapter assembly includes a molded “line cord module” necessary for bringing external power and the M1 line into the base of the CM-16. The inner conductors carry the M1 line and the outer conductors carry the power adapter current. That is why a 6 conductor line cord is required between the base and the power adapter’s “line cord module”.

  What is the output power of the CM-16 handset and Antenna Unit?


Both transmitters have a nominal output power of 200mW.

  How do I Solve CM-16 “Out of Range” or “Pairing” problems?


These problems are mostly due to installation errors and faulty cord connections. Follow these steps in order and you should be able to identify the cause and clear the trouble.

M1 programming and connections…
1) Verify the M1 wall jack operates with a 2616 set connected and that calls can be placed and received at the 2616 set.

Handset battery connection and charge indication…
2) Momentarily disconnect the battery in the handset to power cycle it and then place the handset in its charger stand. After a short period depending on the charge remaining on the battery, the battery charge ICON in the display should appear with blinking bars inside it. Let the battery charge for a few minutes as the handset must power up and respond to key presses before continuing with this process.

CM-16 Antenna Base Station connections and LED indicators…
3) Verify the CM-16 Power Adapter’s short line cord is plugged into the M1-PBX wall jack where you tested the 2616 set. Do not plug this line cord tail into the antenna base station jack as it won’t power the radio correctly.
4) Verify the supplied 6-conductor cord is being used between the antenna base station and the receptacle on the power adapter. This cord carries the M1 circuit on the first pair and power from the adapter to the antenna base station on the third pair (pins 1 and 6). So don’t use the 2616’s 4-conductor line cord. Also, make sure the AC outlet is working. If connections are correct, the left LED should light steady, the center LED should blink continuously and the right LED should blink briefly and turn off.
5) Verify that the right LED blinks when the 6-conductor line cord is plugged into the antenna base station. This indicates the base radio is fully powered and able to search for a handset. When the right Led stops blinking, the handset should be operational.
If the handset is not able to answer or place a call at this point, continue with the pairing process below.

Pairing Process…
You can’t pair the handset to its base unless all circuits are properly powered. This means the 3 LEDs on the antenna base station must be operating as described above and the handset should be responding to key presses. If so, continue below.

6) To “pair” a handset to an antenna base station, start the pairing in the handset first by using Option 7. Press “M”, then 7 on the keypad and then press the “Change” softkey under the display. The display shows “Attempting Pairing” for about 40 seconds, so continue quickly at step 7.
7) While the handset is pairing, power cycle the antenna base station by momentarily unplugging the 6-conductor line cord (2 seconds is long enough). Verify the right LED blinks upon power up.

Watch for the handset display to change to “Pairing Successful”. If all connections and LED indications are as described above, the two units will pair up within 20 seconds. Make a test call to verify the handset is working.
