144RKWL/OtherJumper

The 144 RKWL/OTHER jumper is positioned in the 144RKWL (Rockwell)
position when a 14,400 Rockwell internal composite link modem is used.
When any other internal composite link modem or DSU is used, this
jumper is in the OTHER position. The location of the jumper on the base
is shown in Figure 3-3 and the placement of the jumper is shown in
Figure 3-4.

V.24/V.35 Shunt

An external composite link device with either an RS232C/V.24 or a V.35
interface can be connected to a MultiMux MMH900 series. When an
external composite link device with an RS232C/V.24 interface is
connected to the MultiMux, the V.24 shunt should be installed. When the
external composite link device has a V.35 interface, the V.35 shunt
should be installed. The V.24/V.35 shunt is shown in Figure 3-3. The
factory default for the shunt is in the V.24 position.

V.29/V.33 Shunt and 2834 Shunt

When an internal modem is being installed, the V.29/V.33 shunt or the
2834 shunt has to be in the correct position. This shunt is shown in
Figure 3-3. If a V.29 or V.33 modem is being installed, the shunt has to
be in the V.29/V.33 position. If a MMH2834 modem is being installed,
the shunt has to be in the 2834 position. If an internal ISDN terminal
adapter is installed, the shunt must be in the 2834 position.
