4.5 Activating a CDMA TTU-453
0™
Check with the CalAmp Sales team for availability of the TTU-453
0™ 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 TTU”. The last one is a
little misleading. The ESN on the TTU 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-453
0™ – Verizon
Verizon supports a system that allows CDMA devices to be provisioned Over-The-Air. A CalAmp TTU-
453
0™ will automatically use this system to attempt to self provision. This procedure assumes that the
TTU-453
0™ has never been provisioned or activated before.
1. Power on the TTU-453
0™, 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-453
0™’s modem has registered to the CDMA network.
