Table 3. Out-Of-Band Commands
this condition will be locked until a remote
provisioning command orders the controller card to
switch the customer data back onto the main line, or a
signal failure of greater than 30 seconds occurs on the
protect Slot 8.
Protect Receive Path
The receive path is non-protected and transformer
coupled between the network and the customer. The
receive path is monitored for in-band or ESF
bit-patterned datalink messages. The receive path will
be a passive transmission path.
Protect Transmit Path
The transmit path is non-protected and transformer
coupled between the network and the customer. The
transmit path will be a passive transmission path.
In-Band Commands
The in-band commands are based on a 16-bit repeating
binary pattern. These patterns were selected to avoid
random data replication and yellow alarm generation.
In-band code qualifications involve receiving the codes
for 5 contiguous seconds. The in-band codes can be
transmitted using SF/ESF framing or unframed. See
Table 2 for in-band commands.
Out-of-Band Commands
The out-of-band commands are based on the ANSI
T1.403-1995 standard on T1 protection switching.
ANSI T1.403-1995, Table 4, specifies the command
and response messages for T1 protection switching.
Out-of-band code qualifications involve receiving the
codes for greater than 4 consecutive messages. See
Table 3 for out-of-band commands.
