Sig Bit Inversion
When transmission facilities use bit-oriented signaling (such as CAS), 2 bits are used to transmit seizure
and release signals for calls. Called the A-bit and the B-bit, their meaning can vary. For example, in the
A-bit a “1” might mean on-hook and a “0” might mean off-hook. The entry in the
Country Protocol
field
on the DS1 Circuit Pack screen sets the default meaning of these bits.
For trunk ports on TN2242 and TN464B and later circuit packs, this field allows you to invert the A- and
B-bits as necessary so that the far-end server/switch can understand seizure and release signals from
Communication Manager. If the far-end media server or switch, such as a central office, on this trunk
group interprets the A- and B-bits differently from the default, you may need to invert one or both bits —
to change “1” to “0” and vice-versa in the A-bit, for example.
Supplementary Service Protocol
Appears only when trunk group Type is ISDN.
