Transmit Signaling Bits A for Channel n. Where signaling is enabled, these bits are
transmitted in bit position 8 of the 6th DS1 frame (within the 12 frame superframe structure for
D4 superframes and the 24 frame structure for ESF superframes). This data is obtained from
the CSTi interface but can be overwritten via the Micro port for trunk conditioning applications.
If the MPST bit in the corresponding per timeslot control is not set, this value will be constantly
overwritten by the CSTi stream.
Transmit Signaling Bits B for Channel n. Where signaling is enabled, these bits are
transmitted in bit position 8 of the 12th DS1 frame (within the 12 frame superframe structure
for D4 superframes and the 24 frame structure for ESF superframes).This data is obtained
from the CSTi interface but can be overwritten via the Micro port for trunk conditioning
applications. If the MPST bit in the corresponding per timeslot control is not set, this value will
be constantly overwritten by the CSTi stream.
Transmit Signaling Bits C for Channel n. Where signaling is enabled, these bits are
transmitted in bit position 8 of the 18th DS1 frame within the 24 frame structure for ESF
superframes. In D4 mode these bits are unused. This data is obtained from the CSTi interface
but can be overwritten via the Micro port for trunk conditioning applications. If the MPST bit in
the corresponding per timeslot control is not set, this value will be constantly overwritten by
the CSTi stream.
Transmit Signaling Bits D for Channel n. Where signaling is enabled, these bits are
transmitted in bit position 8 of the 24th DS1 frame within the 24 frame structure for ESF
superframes. In D4 mode these bits are unused.This data is obtained from the CSTi interface
but can be overwritten via the Micro port for trunk conditioning applications. If the MPST bit in
the corresponding per timeslot control is not set, this value will be constantly overwritten by
the CSTi stream.
