Features:
- Up to 12 digital intercom stations share one DXC line-card position.
- Permanent supervision detects station-cable interruption and short circuit.
- Hot-swappable construction supports card service within the documented DXC procedure.
The 12 DDL 02 layout groups twelve monitored station paths behind one front 25-pin Sub-D connection.
Card-level LEDs report operation or failure, while paired indicators for each station separate AF traffic from a local fault.
A PC612-C64 backplane plug carries chassis connections, leaving the RS232 connector and software-update slot accessible at the front.
The INDUSTRONIC 12 DDL 02 341-710-200 Digital Line Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the twelve station lines are organized
- Line count: One card manages as many as 12 digital intercom stations.
- Signal transport: Each line carries digitized AF and control information.
- Separation: Transmission lines are galvanically isolated from the card electronics.
- Station power: The line card supplies the connected intercom terminals within the documented current limit.
Reading card and station indications
- Operation: The card-level green LED indicates normal operation.
- Card failure: A red card-level LED reports a general failure condition.
- AF traffic: One green indicator per station shows incoming or outgoing audio activity.
- Station fault: One red indicator per line identifies a station-specific failure.
Separating service and operating connections
- Controller link: HDLC carries communication between the line card and DXC controller.
- Service access: RS232 is reserved for the documented maintenance interface.
- Station harness: A 25-pin Sub-D female connector terminates the field station lines.
- Chassis plug: The PC612-C64 connector mates the card to the DXC backplane.
Checks before seating the card
- Slot envelope: Allow for a 6 RU, 4 HP front plate and the documented card depth.
- Terminal supply: Confirm the station source remains between 48 and 72 V.
- Thermal range: Keep cabinet operation from 0 °C to +50 °C.
- Post-service test: After a hot swap, verify card LEDs and every station line before returning the exchange to service.
