Part 7. Connecting Optional Equipment

Where you are instructed to run an MMC program while following these procedures, refer to the
Samsung DCS Combined Programming Manual.

7.1 Music On Hold/Background Music

Connect each customer-provided music source to the music input on a MISC (TRK-A) card
connecting block (Figure 7–1). The music input on the MISC card has internal automatic
gain compensation features.
IMPORTANT NOTICE: In accordance with UK law, a license may be required from the
Performing Rights Society or other similar organisation if copyrighted music is transmit-
ted through the Music On Hold feature. Samsung Telecoms hereby disclaims any liabil-
ity arising out of failure to obtain such a license.
Each C.O. line (trunk) can be programmed to receive a music source, system-generated
tone (or no music) when it is put on hold. (See MMC 408.)
Each keyset can have a music source (or no source) for background music. (See MMC
308.)

7.2 External Paging

The MISC card provides a voice pair and two dry contact pairs to be used with customer-
provided paging equipment.
Connect the customer-provided paging equipment to the page output pins of a MISC card
connecting block (Figure 7–2). The relays must be assigned to the page zone in MMC 605.
The page voice pair is 600 ohm impedance. When the amplifier page input is not 600 ohm,
an impedance matching transformer must be used. The paging contact pairs are for con-
trol of low-voltage circuits or amplifier output. The contacts are rated at 24 VDC–1 amp.
WARNING: Do not attempt to connect commercial AC power to these contacts.
