Configuring Modems for Use with Leased Line
Configuration
You must set your panel using direct connect settings rather than the dial
up settings for leased line. Also if you are using leased lines, it is very
important that you understand the decibel (dB) loss specifications of the
lease line to be used. Software House, Sensormatic ACD supports 0 or
-10 dB Loss with the MT1932BL modem and -9 or -15 dB Loss with the
MT2834BL modem. This is controlled on the OEM modem by switch 3.
The dB transmission rate is the strength of the signal being delivered by
the telephone company. A 0-dB transmission level is the strongest signal
possible. After that the -# dB's are used to weaken the strength of the
signal. The telephone company sets most leased lines to a 0-dB loss. The
only time you would need to set a -# dB loss is if you were located near
the telephone company and needed to weaken the signal because of the
close proximity to the source of the signal. In most cases a 0-dB level is
the desired setting. Be sure you verify this information with the telephone
company prior to ordering the OEM modem to ensure you have to proper
model mode for the dB transmission level of your lease line.
