Music-On-Hold/Pager Unit (DMP)
The Music-On-Hold/Pager unit interfaces a standard SX-200 ML DNIC port to the following
external equipment:
• External music source for Music-on-Hold
• External paging amplifier (with or without answerback capability)
• Up to two night bells
• An external alarm
The unit is powered by the SX-200 ML system and does not require a separate power source.
A single 25 pair amphenol connects to the SX-200 ML system via the main distribution frame.
A single LED indicator provides basic status information. The unit can be wall-mounted next
to the SX-200 ML system.
Each Music-on-Hold/Pager Unit supports a single paging zone. If more than one paging zone
is required, additional Music-on-Hold/Pager Units can be added as required.

Datasets
Mitel Networks datasets are proprietary limited-distance modems that provide data facilities for
terminals, digital SUPERSET telephones, and other types of data devices. These datasets
serve as the interface between the DNIC circuit in the PBX, and the data devices connected
to the system, transmitting data and control signals over a single twisted pair of wires. The
datasets are available in three series - DATASET 1100 series, DATASET 2100 series and the
MILINK Data Module.
DATASET 1100 series supports asynchronous data communications at rates from 110 bps
to19.2 kbps. The datasets are RS-232C compatible, and provide end-to-end error correction,
auto-baud detection and auto-parity generation.
