13.5.4 Integrated digital modem

This modem provides remote access over digital trunk or tie trunks as well as via S
circuits.
For all systems in the Hicom 150 E Office product line an integrated B channel modem is available.
With this modem, the system software supports data transmission according to the X.75 protocol.
The digital modem is treated like a pseudo-port and receives an extension number within the system
which can be reached internally and by direct inward dialling. The DID number can be removed
manually in order to prevent external access.
The customer can program an individual 5-digit PIN code in the system administration. In order to
establish communication with the digital modem by means of the PC tool, this individual PIN code
must be entered on the PC tool.
By default, the PIN code does not provide access to the digital modem. This means that the customer
must explicitly obtain access to the modem by entering this PIN code.
The PIN code can be reset to its default value as needed by means of the password-protected system
administration (from the terminal only using Hicom Assistant T).
