INTRODUCTION
The Model BTC-1 Backup Tone Card from
Siemens Industry, Inc. provides two tones
for the MXLV System that can be selected
by dipswitches. This card can be installed on
top of the ACM-1 to provide backup of the
two primary tones should the tone generator
of the ACM-1 fail. The BTC-1 can also be
installed on the OCC-1 Output Control Card
module to provide a default tone when the
low power riser fails and when the OCC-1
loses contact with the MMB.
Select the two backup tones on switch S1 by
matching SW1-SW4 and SW5-SW8 to the
CSG-M (AccuLINK) configuration tone selec-
tions. Table 1 on the next page shows the
switch settings for each available tone.
For additional information on the Voice
System, refer to the MXLV Manual, P/N
315-092036.
INSTALLATION
Remove all system power before installa-
tion, first battery and then AC. (To power
up, first connect the AC and then the battery.)

(See Figure 2) or the OCC-1 (See Figure 3)
with two snap-in type standoffs and a comb-
