Settings screen is set to Yes. If loop back permission is set to Yes then the MIX 56 will —
◊Go into loopback when the loop-up code is no longer received and it had received the loop-up code for at least 5 seconds. A loopback is not established until the loop-up code is no longer received after being received for at least 5 seconds.
◊Go out of loopback when the loop-down code has been received for 5 seconds. A loopback is cancelled after receiving the loop-down code for 5 seconds, it does not wait for the loop-down code to cease being received.
•The low-speed loop-up and loop-down codes can be received and transmitted either via the individual DS1 channel of the MUXed DS3 signal or via the corresponding DS1 line. The MIX 56 can be set up to either the DS3 or DS1 direction but not both at the same time. The low- speed remote loopback direction, DS3 or DS1, is set by the “LS Remote LB Dir” field of the System Settings screen.
◊“LS Remote LB Dir” set for DS3 (default): The loop-up and loop-down codes are received and transmitted on the corresponding DS1 channel of the MUXed DS3 signal. The loopback set on re- ceiving the loop-up code is the low-speed local loopback. A loop- up or loop-down code received on the DS1 line is not recognized.
◊“LS Remote LB Dir” set for DS1: The loop-up and loop-down codes are received and transmitted on the corresponding DS1 line. The loopback set on receiving the loop-up code is the low-speed line loopback. A loop-up or loop-down code received from the cor- responding DS1 channel of the DS3 signal is not recognized.
