2. Digital Cordless Module (MD-1562) description
2.1 Chipset platform
The MD-1562 DECT module is based on a highly integrated chipset for DECT and DECT
VoIP application.
2.2 Numbering system
The customer model number system below provides basic information of model number
assignment for customer to place the order; a label shows the model number would be labeled on each
module delivered!

2.3 Typical application
2.3.1 For base：
The cordless base using the MD-1562 contains a base band section & a RF section. The
antenna(s) will be located outside the module PCB area. To compose a base, the module will
need the additionally hardware interface to support line interface、power supply、handset
charger interface...

2.3.2 For data application：
The MD-1562 for data application can be executed as a MD-1562 base, combined with
one co-processor, which then by the control of the module able to send data back and forth
using the up to 32 Kbits/s air interface.
It is possible to establish a data link from up to five handsets to one base and routing the
data via the UART interface. However, the UART interface has a limited transmission speed up
to 115.2Kb/s baud rate. If more data connections are active at the same time and exceeding the
capacity of the serial bus, the bandwidth of the bus is shared equally between the data
connections.
For the base with MD-1562, it is possible to send data from one handset to another. It is
possible to send Low Speed (6.4Kbits/s) data between two handsets in an intercom through the
base unit.
