Emerald ICE Quick Installation Guide
Page 2-7
The 4SLT Board provides four separate analog device ports. This allows the
Emerald ICE
to sup-
port auxiliary office equipment found on the business premises such as fax machines, PC/Mac
modems and analog telephones (single line telephones). The 4SLT Board generates -30VDC and
20-25Hz, 50V square wave ringing for operation.
The 4SLT Board is equipped with a Heartbeat LED that indicates processing activity on the PCB.
(The 4SLT Board peripheral processor is operating when the Heartbeat LED is flashing.)
The 4SLT Board provides DTMF receivers for each analog port. Ancillary analog devices con-
nected to 4SLT analog ports must generate DTMF signaling. (Pulse dial (rotary-dial) telephones/
equipment are not supported.) All connections are via RJ-11 connectors along the top edge of the
module.
Up to 2- 4SLT Boards may be installed on 610+2 Board and up to 2 on the Base Board.
