Preliminary Information
4-192
Transmit National Bit Buffer (Page 0DH)
Page 0DH, addresses 10H to 14H contain the five bytes of the transmit national bit buffer (TNBB0 - TNBB4
respectively). This feature is functional only when control bit NBTB (page 01H, address 10H) is one.
Receive National Bit Buffer (Page 0EH)
Page 0EH, addresses 10H to 14H contain the five bytes of the receive national bit buffer (RNBB0 - RNBB4
respectively).
Transmit Message Mode Buffer Zero and One (Pages 0FH and 10H)
Pages 0FH and 10H together contain 32 byte storage locations for data that may be transmit onto the equivalent
PCM 30 transmit timeslot. Transmission of these bytes is enabled by setting the TXMSG bits (bit 7) in the
equivalent Per Time Slot Control Register (page 07H and 08H). Table 97 shows the mapping between the Tx
Message Buffer addresses and the equivalent PCM 30 Channels.

Bits Frames 1 to 15. This byte contains the bits transmitted in bit
position n+4 of channel zero of frames 1, 3, 5, 7, 9, 11, 13 and 15 when CRC-4
multiframe alignment is used, or of consecutive odd frames when CRC-4
multiframe alignment is not used. n = 0 to 4 inclusive and corresponds to a byte of
the receive national bit buffer.
