PCM

Operation

4-1.1 Test Mode

To select the span test mode:

1. Press K2 under

TERM

. from the main PCM display. The display advances to read:

SPAN: TERMINATE MON-1 MON-1&2 D&I

2. Press the appropriate soft key (K1-K4) under the desired span type.

TERMINATE

mode enables the 930i to act as a channel bank or switch terminating one end of the span.

MON-1

is used for monitoring one direction of transmission.

MON-1&2

is used to monitor traffic in both directions simultaneously by activating both of the 930i's

receivers.

D&I

mode, or Drop & Insert, is used on live spans between two switches or multiplexers, etc. One of

the channels is dropped-out for testing while the rest pass through undisturbed.

If the 930i is in

MON-1&2

D&I

mode and

TERMINATE

MON-1

mode is selected, the display

reads:

ARE YOU SURE? YES NO

3. Press K4 under

to return to the current mode OR press K2 under

YES

to activate

MON-

4-1.2 Test Direction

To select test direction:

Press K1 under

RECV-1

from the main PCM display to toggle between side 1 and side 2 in the

MON-1&2

D&I

mode without having to swap test cords around. If the 930i is in

TERMINATE

MON-1

mode, the key is inactive because only side 1 is receiving.

4-1.3 Clock

When the 930i is in

TERMINATE

mode, a transmit clock source may be chosen. The 930i can be loop-

timed (

LOOP-TIME

) to the span clock, or it can supply the clock (
