ADTRAN 1xN specifications In-band Protection Switch Protocol, Out-of-Band Enable/Disable Protocol

In-band Protection Switch Protocol	Out-of-Band Protection Switch Protocol
See Table 5 for in-band protection switch protocol.	See Table 7 for out-of-band protection switch
Out-of-Band Enable/Disable Protocol	protocol.
See Table 6 for out-of-band slot enable/disable
protocol.

Table 5. In-Band Protection Switch Protocol

Step	COE In-Band	In-Band Pattern	Controller Card
	Command Patterns
1	Send Arming Code	C440 Hex	Loopback the Arming Code.
2	Send Protection Line	C44X Hex	Loopback the C44X code where X = line number.
	Switch Code	X = Line Number
	Slot Enabled		Perform switchover 5 seconds later. Loss of sync.
	Slot Disabled		Continuous Loopback of the C44X code where X
			= line number. No switchover and no loss of sync.

Table 6. Out-Of-Band Enable/Disable Protocol

Step	COE In-Band	Bit-Oriented Datalink Pattern	Controller Card
	Command Patterns
1	Send Arming Code	0001 1000 1111 1111	Loopback Arming Code for 400 ms followed by AIS.
2	Send Slot Enable or	Enable 0111 1000 1111 1111	Loopback the Enable/Disable code for 400 ms
	Disable Code	Disable 0111 1010 1111 1111	followed by AIS.
	Send Protection Line	0100 XXX0 1111 1111	Loopback line # code for 400 ms followed by AIS.
3	Switch	XXX = Line Number
		(see Table 3)
4	Remove Pattern		Slot is now Enabled or Disabled for protection
			switching.

Table 7. Out-Of-Band Protection Switch Protocol

	COE In-Band	Bit-Oriented Datalink Pattern	Controller Card
Step	Command Patterns
1	Send Arming Code	0001 1000 1111 1111	Loopback Arming Code for 400 ms followed by AIS.
2	Send Protection Line	0100 XXX0 1111 1111	Loopback line # code:
	Switch Code	XXX = Line Number
		(see Table 3)
	Slot Enabled		Perform switchover after 4 consective messages
			received.
	Slot Disabled		Loopback line # code followed by AIS. No switchover.
