LBI-39039B INTERFACES AND REQUIREMENTS
8
2.3. EXTENSION INTERFACE
An extension-originated call appears to the MD110 as a local extension call. This interface can be analog or digital.
Call requirements are as follows:
• Calls to EDACS may require an LCR or EDACS selector code followed by the radio ID.
• Calls to the PSTN typically require an LCR code followed by the PSTN number.
• Calls to another PBX may require an LCR code or an external destination code.
• Calls to MD110 extensions require an extension number.
2.4. SYSTEM ADMINISTRATOR INTERFACE
The system administrator interface is an RS-232 serial communication port; the PC or terminal can configure, test,
troubleshoot, and monitor alarm conditions in the MD110.
Ericsson's standard PC-based communications software is FIOL. It is a DOS-based program included with PC Softdisk
(PCSD) software. PCSD is an Ericsson MD110 file structure emulator for a PC. It allows the MD110 to utilize a PC's hard
drive through a small computer systems interface (SCSI). PCSD may also be used to boot the MD110 should its internal hard
drive fail.
2.5. HARDWARE REQUIREMENTS
The MD110 requires a minimum hardware configuration, which is modified according to customer requirements. The
MD110 is ordered by defining the number and type of trunks, extensions, etc. The Jessica MD110 requires one ISDN trunk
interface for connecting to the PI. The customer determines the PSTN or other PBX interface requirements, and voice/data
extension requirements. The following configuration is for an MD110 mode /50, less PSTN/PBX trunk interfaces.
