7. Select an unused transmit channel time slot using DIP switches SW2-1 through SW2-5 using
direct binary coding as shown in Table 3. Select an unused receive channel time slot using DIP
switches SW3-1 through SW3-5 using direct binary coding as shown in Table 3. Refer to the
multiplexer manual for guidelines on time slot selection.
Note that selecting an invalid time slot will disable the module. In T1 systems, only time slots 1
through 24 are allowed. Time slot 24 is not available for a T1 system using fast reframing.
8. Select transmit bus direction by using DIP switch SW3-6.
Place SW3-6 in the OFF/LEFT position to transmit in the A direction and receive
from the B direction (default). Place SW3-6 in the ON/RIGHT position to
transmit in the B direction and receive from the A direction.
Note: When the OCUDP Module is in a terminal-end multiplexer, the OCUDP
Module must be configured to transmit in direction A.
9. Select the baud rate by using DIP switches SW4-1 to SW4-4 in accordance with Table 4.
10. Set DIP switch SW4-5 to the ON/RIGHT position. OFF/LEFT is currently not supported.
11. Select ZCS (zero code suppression) enable or disable by using DIP switch SW4-6.
Set DIP switch SW4-6 to the OFF/LEFT position to enable ZCS.
Set DIP switch SW4-6 to the ON/RIGHT position to disable ZCS.
12. Select AB signaling enable or disable by using DIP switch SW4-7.
Set DIP switch SW4-7 to the OFF/LEFT position to enable AB signaling.
Set DIP switch SW4-7 to the ON/RIGHT position to disable AB signaling.
13. Select latched loopback functionality by using DIP switch SW4-8.
Set DIP switch SW4-8 to the OFF/LEFT position to enable latched loopback
functionality.
Set DIP switch SW4-8 to the ON/RIGHT position to disable latched loopback
functionality.
Note: Latched Loopback Functionality allows the OCUDP Module to act upon inline
commands to force OCU/DSU loopbacks.
DIP Switch SW4-8 does not cause these loopbacks; it only permits the
function.
