DX-80 & DX-120 7230 APM4 (Call 4 Available)

The card does not include the box, but it is in its original, unopened anti-static bag.

The APM4 provides four separate analog device ports. This allows the DX-80 to support auxiliary office equipment such as fax machines, PC/FAX modems, and analog telephones (single line telephones). The APM4 generates -30VDC and 20-25Hz, 50V square wave ringing for operation.

The APM4 is equipped with a heartbeat LED that indicates processing activity on the PCB; the APM4 peripheral processor is operating when the heartbeat LED is flashing.

When an APM4 is installed via J2 or J3, it takes the place of DPM8 modules that might be installed in those locations. Therefore APM4 modules installed using J2 or J3 will reduce the total number of Digital Port Modules (DPM8) possible.

Comdial DX-80 & DX-120 7210 COM4

The card does not include the box, but it is in its original, unopened anti-static bag.

The COM4 module is installed in the dedicated position via J1 of the 408M/E. The COM4 interfaces four loop-start CO lines. Since one COM4 may be installed in KSU1 and one COM4 may be installed in KSU2, you can expand the DX-120 system loop start CO line capacity to support up to 16 loop start CO lines.

You can add one COM4 to KSU1 and one COM4 to the KSU2. These modules expand the DX-120 system loop start CO line interface capacity to a maximum of eight loop start CO line ports in each KSU (16 total loop startCO line ports when used in KSU 1 & 2).• When adding a COM4 to either KSU, connect to the 408M/E via the COM4 module ribbon cable.- This ribbon cable has the logical system address of SLOT 5 in both cabinet 1 (KSU1-408M) and cabinet 2 (KSU2-408E).• COM4 modules are installed using four 2.0 cm (brass) standoffs.• Always install the COM4 module beneath the CPM module (in KSU1) by first removing the CPM, installing the COM4, and then re-installing the CPM. This is required whenever you install the In-Skin Voice Processor.
