Nortel Networks 3100 manual Subscriber Identity Module SIM card, Battery life

Getting Started

•3 calls per hour (2 inbound, 1 outbound) within an 8 hour workday.

•5 message waiting indicator updates per day.

The following calculation shows data usage per month, assuming 20 work days per month:

Logon and logout attempts

((5 * 1000) + (5 * 900)) * 20 = 190 000 bytes

3 calls per hour (2 inbound, 1 outbound) during an 8 hour day ((2 * 800) + (2 * 900) + 1000) * 8 * 20 = 704 000 bytes

5 message waiting indicator updates

500 * 2 = 10 000 bytes

Client polling (every 90 seconds or 40 an hour)

40 * 700 * 24 hours * 30 days = 20 160 000 bytes The sum of cellular data used per month is:

190 000 + 704 000 + 10 000 + 20 160 000 = 21 064 000 bytes.

Subscriber Identity Module (SIM) card

You can change the subscriber identity module (SIM) card in your device. As long as the new SIM card supports a data connection, the device sends the telephone number associated with the SIM to the MCG 3100 during the log on process. You continue to make and receive calls without changing your client configuration. People calling you do not dial different telephone numbers when you change SIM cards.

Battery life

The battery life of your MCC 3100 device will vary, depending on the amount of use. While operating in standby mode, you can expect 24 hours standby time while connected to a 2G network, and 10 hours standby time while connected to a 3G network.

There are many factors that affect battery life. If you have devices for which you do not get the above standby time, then you should contact Nortel Support to discuss the scenario.
