3. Firmware
description
The standard firmware contains two radio protocols:
•
Connection-based single-bearer mode handles up to 4 connections at a time in point-to-
multipoint applications with payload data rates of up to 26 kBit/s per connection
•
CLDPS packet based transmission mode handles up to 64 PTs operating in a radio cell
at a time in point-to-multipoint applications with payload data rates of up to 500 kbit/s per
radio cell.
3.1 Overview
All functions of the HW 86012/22 are enabled by suitable firmware. This includes the
processing of the DECT communication protocols, the control of interfaces and other
features.
3.1.1 Operation
Modes
The firmware may run in any of the following operation modes:
Operation mode
Purpose
Configuration mode
Set-up module parameters
Data mode
Data transmission using the RS-232 as interface or
voice transmission using the analog frontend or PCM.
Download mode
Load the DECT module with new firmware
The data mode has the following sub-modes
Data sub-modes
Purpose
Transparent data mode
Transparent data transmission over RS-232 interface,
single connection endpoint
Protocol data mode
Connection-based:
Multiplexed data transmission over RS-232 interface,
multiple connection endpoints.
CLDPS packet based:
Ethernet frames over RS-232.
The data sub-mode can be configured by use of the
SPPR
configuration command (see
section 4).
Each of the operation modes has a specific usage of the RS-232 interface. Please refer to
the descriptions of the operation modes.
