DIP Switch SW3 – LBO
DIP Switch SW3 defines LBO. The FCC Part 68 Regulation specifies four grades of attenuation with a step
of 7.5 dB. Three LBOs are used to implement the pulse attenuation.

SW3-1, SW3-2, SW3-3
: Line configuration setting in T1 mode (see “DIP Switch SW4” below)
T1/Short Haul Mode (when SW4-4 = H (Up), SW4-3 = H (Up))
SW3-1, SW3-2, SW3-3: DSX-1 condition
Up, Up, Up: J1 Mode, 110ohm cable (future support);
Up, Up, Down: DSX-1, 162.5-200m,(533-655’) 100ohm cable;
Up, Down, Up: DSX-1, 121.6-162.5m (399-533’) 100ohm cable;
Up, Down, Down: DSX-1, 81-121.6m (266-399’) 100ohm cable;
Down, Up, Up: DSX-1, 40.5-81m (133-266’) 100ohm cable;

T1/Long Haul Mode (when SW4-4 = H (Up), SW4-3 = L (Down))
SW3-1, SW3-2: DS-1 condition
Up, Up: -22.5db 100ohm cable;
Up, Down: -15.0db 100ohm cable;
Down, Up: -7.5db 100ohm cable;
L, L: 0.0db 100ohm cable.
Switch3-4 Inband loopback selection:
Up (H): Disabled
Down (L): Enabled
Note
that PCB builds may vary, and that the particular DIP switch used on your PCB may be labeled dif-
ferently than shown here. The DIP switch labels
UP
,
H
(igh) and
OPEN
typically indicate the same setting,
while
Down
,
L
(ow), and
Closed
all indicate the same configuration setting.
