Analog Extensions
Note: Normally analog extensions are supported using the AEC (VB-43621). 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 5-34for more information.
Guidelines
•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.
•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 AUX1 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.
