Notes:

1 When a DS3 is taken out of service, the Excel platform automatically takes all spans and channels on the DS3 out of service. When the DS3 is brought back in service, the spans and channels are not automatically brought back in service. You must manually bring the spans and channels in service. A DS3 must be in service before any spans can be brought in service. The Excel platform returns a status of DS3 Out of Service (0x5A) if you attempt to bring a span in service first.

2 When bringing a card in service that was previously out of service, the host must wait for a Card Status Report message on the appropriate slot before considering the card in service.

3 When a span is taken out of service, all channels on the span are automatically taken out of service by the Excel platform. When the span is brought back in service using this message, the channels are not automatically brought back in service. You must send this message again to bring the channels back into service.

4 The host should not consider a channel in service upon receiving the Response to this message. The host must receive a DS0 Status Change message with status of "In Service" before considering the channel in service.

5 If you are using E1 Channel 30 for purposes other than CAS (for example, CCS), you cannot include it in a range with other channels. Instead, you must bring E1 Channel 30 into service with a single separate Service State Configure message. Be sure that both the starting and ending spans and channels are set to the span and channel 30.

6 If you take an E1 PPL channel out of service using this message, the host receives the following:
-A DS0 Status Change message (0x42) that has a Channel Status field value of 0x01 (Out of Service).
-A DS0 Status Change message (0x42) that has a Channel Status field value of 0x00 (Purge) and a Purge Reason field value of 0x74 (Disabled While Non-dormant).The system sends this second message to the host as a result of meeting certain criteria but does not actually perform a purge. You can ignore this second message.
