SAMSUNG DCS 70
INSTALLATION MANUAL
PRI CARD (DCS Card)
The PRI card contains one primary rate ISDN access. This card is the same as the DCS PRI
card without the Plastic case. This card has no selectable options. Insert the card into the
dedicated slot in the Expansion cabinet. Push firmly in the middle of both card ejectors on
each card to ensure that it is fully inserted into the backplane connector.
Note: When the PRI card is installed into the system:
1. A PLL card must also be installed
2. Universal card slot 6 must be left vacant.
PLL Board (PLLD70)
The PLL (Phase Lock Loop) card is required when a BRI or PRI card is installed in the DCS
70. The PLL is a daughter card which is installed on the KSU motherboard (See Fig. 4.1).
Align the PLL card with the 14 pin male connectors on the KSU motherboard and push
firmly on the edges of the PLL card in the middle of the 14 pin female connector on either
side of the card.
VDIAL CARD (VDIAL-C) (DCS Compact card)
The VDIAL card is an optional expansion board that is used to provide the voice dialling
feature. The card stores recorded voice patterns and performs the voice recognition function.
There are no options to select on this card. Insert the VDIAL card into any universal card slot
in the KSU or Expansion Cabinet (see Figure 4-1). Push firmly in the middle of both card
ejectors on each card to ensure that it is fully inserted into the backplane connector.
BSI CARD (DECTBSI-C) (DCS Compact Card)
The BSI card is an optional expansion card used to interface to the DECT Base Stations. The
BSI card on the DCS 70 provides connection for three DECT Base Stations. There are no
options to select on this card. Insert the BSI card into any universal card slot in the KSU or
Expansion Cabinet (see Figure 4-1). Push firmly in the middle of both card ejectors on each
card to ensure that it is fully inserted into the backplane connector. Note that only one BSI
card can be installed in the DCS70.
E&M TIE LINE CARD (EMTIEBDD70)
The E&M Tie Line card supports four 6 wire E&M ports. Insert the card into the dedicated
slot in the Expansion cabinet. Push firmly in the middle of both card ejectors on each card to
ensure that it is fully inserted into the backplane connector.
LINE REVERSALS, PRS HYBRIDS & TRANSIT CONNECTIONS
Polarity reversal (PRS) hybrids may be fitted as an option to the 3TRK, 4TRK and 6TRK
cards. The hybrids detect the polarity change at the end of a call and clear down the call.
The exchange line ports must be programmed correctly (Refer to MMC414) for the PRS
hybrids to work.
The operation of the DCS 70 with the PRS hybrid detects polarity reversals a therefore does
not depend on the exchange line being installed with the "correct" polarity ie. if L+ and L-
are reversed the PRS hybrids will continue to work correctly. (The DCS 70 system
automatically detects the polarity of the line in idle).
