3. Channel Bank

Should there be no 2Mbit/s interface available, the Channel Bank will be installed to

interface between the analogue lines of the exchange equipment and the Modem Shelf

in order to provide the required 2Mbit/s traffic link for the AS4000 System.

The 2Mbit/s IN and 2Mbit/s OUT ports on the Modem Shelf are then connected to the

respective 2Mbit/s IN and 2Mbit/s OUT connections on the Channel Bank. Configure

and set the required parameters in the Channel Bank according to the instruction in the

manufacturers manual.
