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. CL75 Disassembly
Note: ESD concept; the internal circuits will be more susceptible to ESD during the
housing exchange. The construction of the internal block 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.
It is a requirement for the service personnel to observe ESD protection rules while
performing service on CL75.
