Interface Unit (RDSU)
The RDSU in its basic configuration provides two
standard telephone ports
digital telephone ports (Circuits 5
Standard Telephone Interface Subunit (RSTS) can be
attached to the RDSU to provide two more standard
telephone ports (Circuits 3 and 4).
The RDSU digital telephone circuits can support any
of the devices that the PDKU can, except for the
DDSS console. The RDSU standard telephone circuits
(including the RSTS circuits) can support all of the
devices that the RSTU and PSTU can. (Alternate
Background Music (BGM) source can be connected to
circuit 2.)
Digital telephones and other devices-except for the
DDCB-that can interface with the RDSU digital
telephone circuits can be connected to any of the
circuits. The DDCB can only be connected to Circuit 5
associated with ports 004, 012, 020 and 028.
Standard telephones and other devices that can
interface with the RDSU standard telephone circuits
(including the RSTS circuits) can be connected to any
of the circuits:
