CLEAR —Clears a switch event not caused by a line failure. |
• |
LOCKOUT PROTECT SPAN —Prevents traffic from reverting to the span with the lockout applied. A lockout overrides other switching commands. |
• |
FORCE RING —Forces a switch. The Force Ring command overrides normal protective switching mechanisms. Applying this command incorrectly can cause traffic outages. |
• |
MANUAL RING —Initiates a switch. |
• |
EXERCISE RING —Tests the MS-SPRing functionality without switching traffic. Ring exercise conditions (including the K-byte pass-through) are reported and cleared within 10 to 15 seconds. The field changes to NO COMMAND after the ring exercise. |
