NTM_n
Name/Description
NT Test Mode.
Controls upstream U-interface overhead bit NTM.
0: NTM = 0, Indicates the NT is in test mode.
1: NTM = 1, Normal operation.
Power Status 1.
Controls upstream U-interface overhead bit PS1. (See PS2 below.)
Deactivate.
When the T9000 device is put in LT mode (DOCR[NT_LT] = 1), this bit becomes the DEA
(turn-off) bit.
Power Status 2.
Controls upstream U-interface overhead bit PS2. According to ETSI ETR 080, PS1 and
PS2 indicate the NT power status as follows:
PS1
PS2
Power Status
0
0
Dying gasp.
0
1
Primary power out.
1
0
Secondary power out.
1
1
All power normal.
S/T-Interface Activity Indicator Control.
Controls upstream U-interface overhead bit SAI. According to
ETSI ETR 080, the SAI bit is set to 1 to indicate to the network that there is activity (INFO 1 or INFO 3) at
the S/T reference point. Otherwise, it is set to 0.
6
PS1
DEA
5
PS2
4
SAI
0: SAI follows activity on S/T-interface per ETR 080.
1: Forces SAI = 1 on the U-interface.
U-Interface Only Activation.
When the T9000 device is put in LT mode (DOCR[NT_LT] = 1), this bit
becomes the UOA (U-only-activation) bit. This bit needs to be set to 1 to allow S/T activation at the NT.
Force U-Block Upstream Data Transparency.
Asserts U-block XPCY bit,
forcing U-block upstream 2B+D
data transparency.
UOA
3
XPCY
0: No effect on device operation.
1: Forces U-block data transparency.
Force U-Interface Upstream ACT Bit.
Normally, the state of the upstream ACT bit tracks the received
INFO3 state on the S-interface. However, in cases where there is no TE attached, this bit allows manual
control of the upstream ACT bit (via the ACTUP bit, below).
2
F_ACTUP
0: ACT bit follows INFO 3.
1: ACT bit follows ACTUP bit (see ACTUP below).
Force U-Interface Downstream ACT Bit.
When the T9000 device is put in LT mode (DOCR[NT_LT] = 1),
this bit controls the downstream ACT bit (via the ACTDN bit, described below).
F_ACTDN
0: Downstream ACT bit is zero.
1: Forces the value of ACTDN bit (described below) to be transferred downstream.
ACT Upstream.
Only valid when F_ACTUP bit is set (see F_ACTUP above). It controls the state of the
upstream U-interface ACT bit.
1
ACTUP
0: Forces upstream ACT bit = 0.
1: Forces upstream ACT bit = 1.
ACT Downstream Bit.
When the T9000 device is put in LT mode (DOCR[NT_LT] = 1), this bit controls the
state of the downstream U-interface ACT bit.
ACTDN
0: Forces downstream ACT bit = 0.
1: Forces downstream ACT bit = 1.
