4mA
Receive Channel n Data Negative Rail, TU/VT Framing
Pulse: When control bits RnLINT1/0 are set to 10, negative rail
E1/T1 data (RNOn) is provided on this lead. When control bits
RnLINT1/0 are set to 11, a VT/TU framing pulse (RVTFn) is
provided on this lead. This lead is disabled when control bits
RnLINT1/0 are 00. When disabled, this lead can be forced to
ether a high impedance state (control bit RnOUTL is a 0), or to
zeros (control bit RnOUTL is a 1). Lead Y13 is RNO1/RVTF1
(Channel 1).
Note: See Description for control bit RnOUTL for detailed oper-
ation. Output will be forced low during normal operation while in
NRZ mode.
Transmit Channel n Rail, NRZ Input Clock, VT/TU Output
Clock: A DS1 or E1 clock input when the Rail or NRZ interface
is selected or a VT/TU clock output when the VT/TU interface is
selected. TCIn is the E1/T1 rail clock (control bits TnLINT1/0
(bits 7/6, register X+002H) are 10). TCLKn is the E1/T1 NRZ
clock (control bits TnLINT1/0 are 01). TVTCn is the VT/TU NRZ
clock output (control bits TnLINT1/0 are 11). Rail (TPIn/TNIn),
NRZ (TDATn/TLOSn) or VT/TU NRZ data (TVTDn) is clocked
in on negative transitions of this clock when control bit TnCLKI
(bit 3, register X+002H) is a 0. When control bit TnCLKI is a 1,
data is clocked in on positive transitions of this clock. Lead
AA14 is TCI1/TCLK1/TVTC1 (Channel 1).
When control bits TnLINT1/0 are set to 10, positive rail E1/T1
data (TPIn) is clocked in this lead. When control bit TnLINT1/0
are set to 01, NRZ E1/T1 data (TDATn) is clocked in on this
lead. When control bits TnLINT1/0 are set to 11, VT/TU NRZ
data (TVTDn) is clocked in on this lead. Lead AB14 is
TPI1/TDAT1/TVTD1 (Channel 1).
Signal, Coding Violations: When control bits TnLINT1/0 are
set to 10, negative rail E1/T1 data (TNIn) is clocked in on this
lead. When control bits TnLINT1/0 are set to 01, an external
loss of signal (when control bit EXnLOS (bit 1, register
X+003H) is a 1) is clocked in on this lead. When control bit
EXnLOS is a 0, external coding violations can be clocked in on
this lead. Lead W13 is TNI1/TLOS1.
