Connecting BRM-2 Cables to a European System
Connecting DDM-16 Station Cables to the MDF
Digital telephones are connected to DDM-16 ports. Single line devices are connected to Single-Line
Adapters (SLA) which are in turn connected to available DDM-16 circuits.
Besides single line phones, playback devices, and off-premises extensions, SLAs can also be used
to install DID trunks. Any combination using the two circuits on the SLA is possible.
After the station cables are run, connect them and the 25-pair cables to the DDM-16 blocks on the
MDF as follows:
