S/G ... Stop/Go Bit Monitoring
Indicates the availability of the upstream D-channel on the S/T interface.
1: Stop
0: Go
BAS ... Bus Access Status
Indicates the state of the TIC-bus:
0: the IPAC-X itself occupies the D- and C/I-channel
1: another device occupies the D- and C/I-channel
Note: The CODR0 bits are updated every time a new C/I-code is detected in two

CIX0
CODX0 ... C/I-Code 0 Transmit
Code to be transmitted in the C/I-channel 0. The code is only transmitted if the TIC bus
is occupied. If TIC bus is enabled but occupied by another device, only “1s” are
transmitted.
TBA2-0 ... TIC Bus Address
Defines the individual address for the IPAC-X on the IOM bus.This address is used to
access the C/I- and D-channel on the IOM interface.
Note: If only one device is liable to transmit in the C/I- and D-channels of the IOM it
BAC ... Bus Access Control
Only valid if the TIC-bus feature is enabled (MODED.DIM2-0).
If this bit is set, the IPAC-X will try to access the TIC-bus to occupy the C/I-channel even
if no D-channel frame has to be transmitted. It should be reset when the access has been
completed to grant a similar access to other devices transmitting in that IOM-channel.

consecutive IOM-frames. If several consecutive valid new codes are detected and
CIR0 is not read, only the first and the last C/I code is made available in CIR0 at
the first and second read of that register, respectively.
