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.

An card (VB-43431) is required when the AEC is used. The MFR

among the analog extensions.
