2 Remark

All instructions given in this document are valid for AP75.

3 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.

8 ESD Protection

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.

It is a requirement for the service personnel to observe ESD protection rules while

performing servicing the AP75.

Reference for ESD Protection is the manual:
