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.
5.
The message waiting circuitry only illuminates the message lamp when the station
is idle. Therefore, an 8SLI card and the 8MWSLI card follow the same configuration
rules when considering a single or double power supply.
3.24 16MWSLI CARD
There are no options to select on this card. Insert up to seven 16MWSLI cards as are
needed into universal slots 1 through 9
. 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 16MWSLI 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 16MWSLI 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.
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.

3.25 TEPRI CARD
The TEPRI card installs in slots 1, 2 or 3 of any cabinet. The iDCS 500 TEPRI supports
either T1 or ISDN PRI service. The first four LEDs on the front of the card provide the
status of the service (Sync, AIS, Loss and Layer 2 Active states). The second four LED’s
on the front of the card display the type of service. The first TEPRI card installed in the
iDCS 500 is the primary source of external clocking. The second TEPRI installed is the
secondary source of external clocking. Default clock selection is first cabinet, left to
