6. Place the main-board back into the TTU-12x0™’s bottom plate.
7. Snap the TTU-12x0™’s cover back in place.
4.5 Activating a CDMA TTU-12x0™
Check with the CalAmp Sales team for availability of the TTU-12x0™ with CDMA modems. For CDMA devices,
the activation sequence you will use varies from carrier to carrier. Each of the supported carriers is documented below.
To obtain an account, a CDMA carrier will generally ask for three things, the Manufacturer, the Product Type and the ESN.
Obviously the first two items are answered by “CalAmp LMU”. The last one is a little misleading. The ESN on the LMU is
the CalAmp serial number. The one the operator is interested in is the MSN-D (which they call the decimal ESN). DO NOT
give them the CalAmp ESN (i.e. the top one on the label). It will only lead to the carrier telling you that the product doesn’t
exist and they can’t activate it for you.
What you should get back will vary from operator to operator; however at very least it will be the MDN (Mobile Directory
Number) and MIN (Mobile Information Number). You should also ask for the SPC (Service Programming Code) in case it
is not 000000. The SPC is effectively a password to the modem which allows you to program some of the more sensitive
items (ex: the MDN and MIN). Please note that the MIN and MSID can be the same value.
4.5.1 Activating a CDMA TTU-12x0™ – Verizon
Verizon supports a system that allows CDMA devices to be provisioned Over-The-Air. A CalAmp TTU-12x0™ will
automatically use this system to attempt to self provision. This procedure assumes that the TTU-12x0™ has never been
provisioned or activated before.
1. Power on the TTU-12x0™, making sure you can observe the behavior of the Comm LED.
2. Wait until the Comm LED turns solid. This could take up to 5 minutes.
3. If after 5 minutes you observe that the Comm LED transitions from a slow blink to a fast blink several times (i.e.
more than twice) you will need to contact Verizon Wireless for further support on account activation.
Once configured, you may verify that the TTU-12x0™’s modem has registered to the CDMA network. Enter:
AT$APP COMM STATUS?
The response should be similar to:
CDMA Service:
IS-2000
Connection:
Yes
RSSI:
-80 dBm
Channel:
0
Band:Side:
800:B
Base Station ID: 0
Network ID:
0
System ID:
4
ESN (Modem S/N:
2676319948 [9F8566CC]
Phone Number:
1234567890
IMSI:
310001234567890
CarrierConfig:
5
Note that the Phone Number should match the MDN value the carrier gave you. The last 10 digits of the IMSI field should
match the MIN/MSID value they gave you.
For devices that have had previous activations, an Over-The-Air activation process may be manually started using a single AT
Command:
