Figure 4-51. Specifying Zero Suppression Mode

Remote alarms (D/I Mux III sending yellow alarms) can be directed. In channel bank mode, the choices

are T1-1 REM Alarm output, or none; in dual channel bank mode, the choices are T1-1, or none, and T1-

2, or none. In drop-and-insert mode (as depicted in the example in Figure 4-50), select T1-1, T1-2, both,

or none.

If using a Data Service Unit Data Port (DSUDP) line card, the direction and transmission port selection

must be set, as is the case for all individual line cards. The direction is user-configurable unless the

mode of operation dictates the direction of transmission.

Typically, use the T1-1 port when in channel bank mode. Use both ports when in dual channel bank and

ALPS modes. For drop-and-insert mode, use both T1-1 and T1-2 ports.

Use the Set shelf Configuration (SC) command to configure the transmission direction, specifying mode

of operation, port, and timing mode options.
