Carrier module (4-fold) to accommodate max. 4 module attachments.
Module attachments are available for the following purposes:
E1-Attachment (2Mbit) for direct system internetworking, by DSL modem or transmission
technology
ISDN-Attachment for PA, IC and fault message calls over an ISDN network
Uart-Attachment (RS232) for user-defined specific controls
In the configuration of module, the operating mode of the ports has to be selected according to the
module assembly.
Firmware,
BUS-CPU
If it is a module with bus CPU, the option has to be activated! Modules of newer design (with
bus CPU, recognizable by additional board and SMD assembly) do not have restrictions
regarding the audio channel pool anymore. All dynamically allocated audio channels can be
used. This will allow for AF switching between different modules and diverting of AF in case
of direct forwarding.
Operation mode
E1 (2Mbit)
Control
channel
The transfer of control data can be done either in the channel 0 or 16. For non-transparent
transmission systems, which do not allow for different re-use of their own service channel,
channel 16 can be deployed.
