Analog Extensions
Note: Normally analog extensions are supported using the AEC (VB-4362 1).
Alternatively, a Single Line Telephone Adaptor (SLTA, VB-43709) may be
used to support analog DTMF (2500 set) extensions. The SLTA converts up
to 4 digital ports to analog ports. See “Single Line Telephone Adaptor” on
page 5-34 for more information.
Guidelines
l
An MFR card (VB-43431) is required when the AEC is used. The MFR
card, which provides DTMF signals, includes eight circuits that are shared
among the analog extensions.
l
The AEC also requires the SLT ringer.box (VB-2089P).
Installation
1.
Install the AEC cards in extension slots.
2.
Install the MFR card in
AUXl
or AUX2. If installing in a two-cabinet
system, see Chapter 6 for specific information for installing MFR card(s).
3.
Install the SLT Ringer Box as shown in Figure 4-14. Be sure to note the
differences between the DBS 40 Connector Panel and the Connector
Panel on the DBS 72 and 96.
