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 code followed by the radio ID.

• Calls to the PSTN require an LCR code followed by the PSTN number.

• Calls to MD110 extensions require an extension number.

2.4. SYSTEM ADMINISTRATOR INTERFACE

The system administrator 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).

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 interface requirements and voice/data extension

requirements. The following configuration is for an MD110 model /50, less PSTN trunk interfaces.

2.5.1. Minimum Configuration

The minimum configuration for the MD110 is as follows:
