Level III Service Manual Product Overview

Product Overview

Motorola PF B95 and C21 mobile telephones feature global system for mobile communications (GSM) air interface, general packet radio service (GPRS) transport technology, and wireless application protocol (WAP) Internet browser. PF B95 and C21 incorporate a simplified icon and list-based user interface (UI) for easier operation, allow short message service (SMS) text messaging, and include clock, alarm, datebook, calculator, and caller profiling personal management tools. The PF B95 is a dual band phone that allows roaming within the GSM 900 MHz and digital cellular system (DCS) 1800 MHz bands. The PF C21 is a single band phone operating in the personal communications services (PCS) 1900 MHz band.
PF B95 and C21 telephones support GPRS and SMS in additi on to traditional circuit switched transport technologies. GPRS, where available, provides substantial increases in mobile data communications performance and the efficie nt use of radio spectrum. Data transmission rates for GSM networks can potentially increase fro m the current rate of 9.6 kbps up to a theoretical maximum of 171.2 kbps. An increased data rate is by no means the only ben efit provided by GPRS. A key advantage is the provision of a permanent virtual connection to the network. This “always on” connection is possible because GPRS uses packet data transfer so that, for example, email can be downloaded in “background mode.” There is no need for the user to re­connect before requesting a service, eliminating connection set-up delays and adding convenience and immediacy to data services access. The “virtual” nature of this connection means that network resources are not consumed during periods when a user is not actually sending or receiving data.
The telephones are made of polycarbonate pla stic. The display and speaker, as well as the 16-key keypad, transceiver printed circuit board (PCB), microphone, charger and headphone connectors, and power button are con tained within the J form-factor housing. The user-replaceable 600 mAh nickel metal hydride (NiMH) battery provides up to 300 minutes of talk time with up to 180 hours of standby time phone accepts 3V mini subscriber identity module (SIM) cards which fit into the SIM holder underneath the battery. These telephones feature a 96 x 64 pixel 800 square millimeter high-resolution graphics display and an internal antenna.

Features

PF B95 and C21 telephones use advanced, self-contained, seal ed, custom integrated circuits to perform the complex funct ions required for GSM GPRS communication. Aside from the space and weight advantage, microcircuits enhance basic reliability, simplify maintenance, and provide a wide variety of operational functions.
Features available in this family of telephones include:
• Lower voltage technology that provides increased standby and talk times
• Extended GSM (EGSM) channels (PF B95 only)
• Tri-coder/decoder (CODEC) that allows full rate, half rate, and enhanced full
rate modes of transmission
• Supports SMS, concatenated SMS, and cell broadcast messages
• Supports GPRS, circuit switched, and SMS networks
• WAP 1.1 compliant
1. All talk and standby times are approximate and depend on network configuration, signal strength, and features selected. Standby times are quoted as a range from DRX=2 to DRX=9. Talk times are quoted as a range from DTX off to DTX on.
2. Network, subscription and SIM card or service provider dependent feature. Not available in all areas.

Speaker Dependant Voice Activation
The voice dialing fea ture a l lows the use r to reca ll p re-p rogra mmed v oice numbers simply by pressing the Voice/Ok key and speaking the desired voice tag. Up to 10 voice tags can be stored.
The user cannot place or receive calls while adding voice tags to the phone’s memory.
Because the GSM standard does not provide the option to store voice tags onto the SIM card, voice tags are added to the phone’s memory.
Wireless Access Protocol (WAP) 1.1 Compliancy
In the WAP environment, access to the Internet is initiated in wireless markup language (WML), which is derived from hypertext marku p language (HTML). The request is passed to a WAP gateway which retrieves the information from the server in standard HTML (subsequently filtered to WML) or directly in WML if available. The information is then passed to the mobile subscriber via the mobile network.
The PF B95 and C21’s microbrowser can be configured for baud, idle timeout, line type, phone number, and connection type.
Bitmap image data will download as text. If the image is larger than the screen, only part of the image will display.

Level III Service Manual Product Overview
Simplified Text Entry
iTAP™ predictive text entry. Press a key to generate a character and a dynamic dictionary uses this to build and display a set of word or name options. The iTAP™ feature may not be available on the phone in all languages.
Caller Line Identification
Upon receipt of a call, the calling party’s phone number is compared to the phone book. If the number matches a phone book entry, that name will be displayed. If there is no phone book entry, the incoming pho ne number will be displ ayed. In the event that no caller identification information is available, an incoming call message is displayed.
➧
User must subscribe to a caller line identification service through their service provider.
SIM Toolkit™ - Class 2
SIM Application Toolkit is a value-added service delivery mechanism that allows GSM operators to customiz e the services they offer their customers, from the occasional user who requests sports news and traffic alerts, to a high call time business user who re ceives stock a lerts and checks flight times. Operators can now create their own value- added services menu quickly and easily in the phone. The customized menu will appear as the first menu and may be updated over-the-air with new services when customers request them.
Network Based Chat Messaging
The chat messaging feature p rovides a constant WAP co nnection through GPRS t o carrier, service center, or factory flexed WAP site. The specific site can also be entered by the user. Chat messaging is a carrier option.
Other Features
Detailed descriptio ns of these and the other features can be found in t he appropriate PF B95 and C21 telephone user guides listed in the Related Publications section toward the end of this manual.

All batteries can cause property damage and/or bodily injury such as burns if a conductive material such as jewelry, keys, or beaded chains touch exposed terminals.
E
The conductive material may complete an electrical circuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly when placing it inside a pocket, purse, or other container with metal objects.
