Page 0FH, addresses 10H to 1FH contain the 16 bytes of transmit message buffer zero
Page 10H, addresses 10H to 1FH contain the 16 bytes of transmit message buffer one
Receive Message Mode Buffer Zero and One (Pages 11H and 12H)
Pages 11H and 12H - Receive Message Buffer 0 and 1 respectively, contain 32 bytes of memory. Each byte is
updated once per frame by the equivalent PCM 30 channel from the receive data stream.

Transmit Bits 7 to 0. This byte is transmit on a time slot when selected by the
TXMSG bit of the appropriate per time slot control word. n = 0 to 15 and represents
transmit timeslot numbers 0 to 15.
Transmit Bits 7 to 0. This byte is transmit on a time slot when selected by the
TXMSG bit of the appropriate per time slot control word. n = 0 to 15 and represents
transmit timeslot numbers 16 to 31.
Receive Bits 7 to 0. Each byte is sourced from a time slot coming from the line data.
n=0 to 15 represents receive timeslots 0 to 15.
