Transmit Overhead Input (TxOHn):
The exact function of these pins depends on the mode of oper-
ation selected, as described below.
DS1 Mode
These pins operate as the source of Datalink bits which will be
inserted into the Datalink bits within an outbound DS1 frame if
the framer is configured accordingly. Datalink Equipment can
provide data to this input pin using the TxOHCLKn clock at
either 2kHz or 4kHz depending on the transmit datalink band-
width selected.
N
OTE
:
This input pin will be disabled if the framer is using the
Transmit HDLC Controller, or the TxSER input as the
source for the Data Link Bits.
E1 Mode
These pins operate as the source of Datalink bits or Signaling
bits depending on the framer configuration, as described
below.
Sourcing Datalink bits from TxOHn:
The E1 transmit framer will output a clock edge on TxOHCLKn
for each Sa bit that has been configured to carry datalink infor-
mation. Terminal equipment can then use TxOHCLKn to pro-
vide datalink bits on TxOHn to be inserted into the Sa bits
within an outbound E1 frame.
Sourcing Signaling bits from TxOHn:
Users must provide signaling data on TxOHn pins on time slot
16 only. Signaling data (A,B,C,D) of channel 1 and channel 17
must be inserted on the TxOHn pin during time slot 16 of frame
1, signaling data (A,B,C,D) of channel 2 and channel 18 must
be inserted on the TxOHn pin during time slot 16 of frame
2...etc. The CAS multiframe Alignments bits (0000 bits) and
the extra bits/alarm bit (xyxx) must be inserted on the TxOHn
pin during time slot 16 of frame 0.
N
OTE
:
These 8 pins are internally pulled “Low” for each
channel.
