Transmit Buffer Zero Connect. If one,
the contents of the transmit circular
buffer zero will be transmitted in the
corresponding time slot beginning at
the next multiframe boundary. If zero,
circular buffer zero is not connected
to this time slot. This buffer is acces-
sible only in processor and controller
modes.
7 - 0 TxB0.n .7 - Transmit Bits 7 to 0. This byte is
transmitted on a time slot selected by
TxB0.n .0
the TBUF0 bit of the appropriate per
time slot control word. n = 0 to 15 and
represents a byte position in Trans-
mit Circular Buffer zero (TxB0).
Table 19 - Transmit Circular Buffer Zero (Page 9)
Page 0AH, addresses 10000 to 11111 contain the 16
bytes of transmit circular buffer one (TxB1.0 to
TxB1.15 respectively). This feature is functional only
in processor and controller modes.

Transmit Buffer One Connect. If one,
the contents of the transmit circular
buffer one will be transmitted in the
corresponding time slot beginning at
the next multiframe boundary. If zero,
circular buffer one is not connected
to this time slot. This buffer is acces-
sible only in processor and controller
modes.

transmitted on a time slot selected by
the TBUF1 bit of the appropriate per

TxB1.n .0
Receive Buffer Zero Connect. If one,
the data of the corresponding receive
time slot will be recorded in receive
circular buffer zero beginning at the
next multiframe boundary. If zero, cir-
cular buffer zero is not connected to
this time slot. This buffer is accessi-
ble only in processor and controller
modes.
