After these programming steps, the control memory will have the following content:
Figure 65
Control Memory Contents for Decentral D-Channel Handling
Central D-Channel Handling Scheme
This option applies for IOM channels where the even time slot consists of an 8 bit monitor
channel and the odd time slot of a 2 bit D-Channel followed by a 4 bit C/I channel
followed by the 2 monitor handshake bits MR and MX.
The monitor channel is handled by the MF handler according to the selected protocol,
handshake or non-handshake. If the handshake option is selected (IOM-2), the MF
handler controls the MR and MX bits according to the IOM-2 specification. If the
non-handshake option is selected (IOM-1), the MF handler sets both MR and MX bits to
