This nibble is programmed to provision the number of con-
secutive errored phase indications required to transition
into the VT_LOPS[1—28]
byte synchronous mode.
Note: The valid range of values is 0x1—0xF. A value of
H4 Multiframe Indication NTIME Detection Control.
This nibble is programmed to provision the number of con-
secutive errored multiframe indications required to transi-
tion into the VT_H4LOMF
Note: The valid range of values is 0x1—0xF. A value of
Z6 Byte Monitor NTIME Detection Control. This nibble
is programmed to provision the number of consecutive
consistent Z6 bytes required to accept a new value.
Note: The valid range of values is 0x1—0xF. A value of
J2 Byte Monitor NTIME Detection Control. This nibble
is programmed to provision the number of consecutive
consistent J2 sequences required for the J2 byte monitor
to transition in and out of J2TIM.
Note: The valid range of values is 0x1—0xF. A value of
Pointer Interpreter Invalid Pointer NTIME Detection
Control. This nibble is programmed to provision the
number of invalid pointers required for the pointer inter-
preter to go into the VT_LOP[1—28]
Note: The valid range of values is 0x1—0xF. A value of
Control. This nibble is programmed to provision the
number of consecutive NDF pointers required for the
pointer interpreter to go into the VT_LOP state.
Note: The valid range of values is 0x1—0xF. A value of
0x0 will be mapped to 0x1.
