1 GPRS (General Packet Radio Service)

GPRS is a new non-voice value added services that allows information to be sent and received across a GSM mobile telephone network. It supplements today’s Circuit Switched Data (CSD) and Short Message Services (SMS). GPRS involves overlaying a packet based air interface on the existing circuit switched GSM network. This gives the option to use a packet-based data service. The information is split into separated but related “packets” before being transmitted and reassembled at the receiving end. Theoretically, maximum speeds of up to 171.2 kilobits per second (kbps) are achievable with GPRS using all eight timeslots at the same time. This is about 3 times as fast as the data transmission speed possible over today’s fixed telecommunications networks and 10 times as fast as current Circuit Switched Data services on GSM networks

Example: Cell with 1 Frequency channel: 1 physical channel for signaling, 4 physical channels for Circuit switched and 3 physical channels for Packet switched.

5.1 M75 Interface to accessories

The phone has got a full compatible interface to accessories. The I/O-Connector (Lumberg-(slim)-connector) and RF-Connector is in the same position as in the 65series Because of the M75 design it’s not possible to use the same car holder as R65 Ulysses. All shown interfaces are for car-cradle. Interfaces for Belt-Clip will not be necessary.

7 Disassembly of M75

Note: ESD concept; the internal circuits will be more susceptible to ESD because of

the use of exchangeable housing. The construction of the internal block must be/is designed, in the best possible way, to protect the circuit against sparks.

The keypad must be completely closed to prevent any occurrence of an ESD disruptive discharge.

The SIM contacts may be open, thus reachable for ESD contact discharge. This could lead to damage or destruction of the S-Goldlite pins.

It is a requirement for the service personnel to observe ESD protection rules while performing servicing the M75.
