8MWSLI Card
There are no options to select on this card ( Figure 4-15 ). Insert as many 8MWSLI cards as are
needed into universal slots 1 to 7 ( Figure 4-2 ). Push firmly in the middle of both card ejectors on
each card to ensure that it is fully inserted into the backplane connector.
This card automatically detects DTMF or dial pulse signals from an SLT. Software and hardware
settings are not required. The 8MWSLI supports industry standard message waiting lamps on
SLTs. The message waiting power supplied to an SLT station is 90–100 VDC. The 8MWSLI has
no DTMF receivers; it will share the system-wide DSP resources for DTMF decoding. If there is
a medium to high concentration of 8MWSLI cards or traffic, one or more MFM daughterboards
should be added to a processor card or cards to relieve congestion.
NOTE:
1. Do not connect devices with a total REN greater than 5.0 to this card.
2. Ring Frequency: 25 Hz square wave
Ring Voltage: 120 volts peak to peak, 20 milliamps of current
3. SLI port feed voltage is nominally 50VDC.
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 an 8MWSLI card follow the same configuration rules
when considering a single or double power supply.
16MWSLI Card
There are no options to select on this card ( Figure 4-15 ). Insert up to seven 16MWSLI cards as
required into universal slots 1 to 7 ( Figure 4-2 ). Push firmly in the middle of both card ejectors on
each card to ensure that it is fully inserted into the backplane connector.
