will share the system resources. If in a medium to high concentration of 16SLI cards or
traffic, a MFM daughter board or boards should be added to a processor card or cards
to relieve congestion.
NOTES:
1. If a cabinet is equipped with a single power supply unit (PSU-60B), a maximum of
56 station devices may be connected to that cabinet. However, if the cabinet is
equipped with two power supply units, a maximum of 120 station devices may be
connected to that cabinet.
See the configuration section of the General Description
Section for more details.
2. Do not connect devices with a total REN greater than 5.0 to this card.
3. Ring Frequency: 20 Hz square wave. Ring Voltage: 120 volts peak to peak, 20
milliamps of current
4. This card does not contain OPX over voltage protection circuitry.
3.22 BRI CARD ( see Figure 3–17 )
The iDCS 4BRI card is equipped with DIP switches to control the insertion of
termination resistors into the BRI circuits. These DIP switches should be in the ON
(default) position if the circuits on the BRI card are to be used as stations and the
switches should be OFF if connected to a trunk. DIP 1 controls Circuit 1, DIP 2 controls
Circuit 2, DIP 3 controls Circuit 3, and DIP 4 controls Circuit 4.
See Figure 3-24 for DIP
switch locations. Once the DIP switches have been correctly set insert the card into any
universal slot. See Figure 3-1 . Push firmly in the middle of both card ejectors on each
card to ensure that it is fully inserted into the back plane connector.
3.23 8MWSLI CARD ( see Figure 3–17 )
There are no options to select on this card. Insert as many 8MWSLI cards as are
needed into universal slots 1 through 9
(see Figure 3–1) . Push firmly in the middle of
both card ejectors on each card to ensure that it is fully inserted into the back plane
connector.
This card automatically detects DTMF or dial pulse signals from the SLT. Software and
hardware settings are not required. The 8MWSLI supports industry standard message
waiting lamps on single line phones. The message waiting power supplied to the single
line station in the iDCS is 90 to 100 VDC. The 8MWSLI has no DTMF receivers; it will
share the system wide DSP resources for DTMF decoding. If in a medium to high
concentration of 16SLI cards or traffic, a MFM daughter board or boards should be
added to a processor card or cards to relieve congestion.
