The HSU-AD 530/35 Card supports two RS-530 or V.35 CPE devices. The selection of
RS-530 or V.35 is made on a port-by-port basis using on-board switches as described below.
This card also supports V.25bis dialing (an inband dialing protocol) and RS-366 dialing
through separate DB-15 RS-366 jacks on the card. The HSU-AD 530/35 Card also has a
proprietary inband performance monitoring system.
1.2.4.1 HSU-AD Card Jumper/Switch Settings
Set the card switches for operation of ports 1 and 2 in either the RS-530 or V.35 mode. These
switches are shown in Figure 1-2; they are factory-set for RS-530 operation. To change a port
to V.35 operation, reset its switch as shown. The ports can be set individually for either RS-530
or V.35 operation, but once you set them, they remain in that mode until the slide switches are
reset. RS366 Dialing Port #1 and RS366 Dialing Port #2 are dialing ports for Port #1 and Port
#2 (HSU RS530/V.35) respectively; they serve no other purpose.
