Table 5-8. Signaling and Trunk Conditioning Values (1 of 2)

Network

Side Value Meaning

DSX-1 Side

Default

Value

None No signaling used on this DS0. Use this setting if there is
no voice signaling information being passed on this DS0
(clear channel).
None
RBS
(default) Robbed Bit Signaling is used on this DS0, but no trunk
conditioning. Signaling bits will be passed to the T1
interface to which this DS0 is cross-connected when this
T1 interface is not in CGA, but the signaling bits will be all
ones when CGA is present.
RBS
The following values will configure the cross-connect for RBS, as well as perform the
trunk conditioning indicated when a CGA condition occurs. Although the ABCD signaling
bits for each setting are described, only AB bits are transmitted when the
cross-connected T1 interface is using D4 framing.
E&M-idle The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the idle state for an E&M
interface (ABCD = 0000).
E&M idle
E&M-busy The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the busy state for an
E&M interface (ABCD = 1111).
E&M busy
FXOg-idle The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the idle state for an FXO
Ground-Start interface (ABCD = 1111).
FXSg-idle
FXOg-busy The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the busy state for an
FXO Ground-Start interface (ABCD = 0101).
FXSg-busy
FXOl-idle The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the idle state for an FXO
Loop-Start interface (ABCD = 0101).
FXSl-idle
FXOl-busy The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the busy state for an
FXO Loop-Start interface (ABCD = 0101).
FXSl-busy
FXSg-idle The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the idle state for an FXS
Ground-Start interface (ABCD = 0101).
FXOg-idle
FXSg-busy The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the busy state for an
FXS Ground-Start interface (ABCD = 1111).
FXOg-busy
FXSl-idle The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the idle state for an FXS
Loop-Start interface (ABCD = 0101).
FXOl-idle
FXSl-busy The signaling bits transmitted to the cross-connected T1
interface during a CGA represent the busy state for an
FXS Loop-Start interface (ABCD = 1111).
FXOl-busy
