Table 3 - Local Data Memory
5.3
Connection Memory use in Conferencing, Gain Control and specifying Incoming Sources for
Energy Detect and DBR
Connection Memory is used to specify the source and gain for the 64 outgoing channels of STo0 and STo1 and
the 128 outgoing channels of the expansion bus. Message mode, Minimum or Constant Delay and Output
Enable are specified in CMH for each of these channels.
The conference circuit incoming channels are specified in CML 60-6E. The incoming conference gain,
inversion bit and noise suppression are specified in CMH. Message mode, Minimum or Constant Delay and
Output Enable are not used for locations 60-6E reserved for conference control. See the description of
“Connection Memory High” on page 50. Channels are transferred from Data Memory with Constant Delay to
the conference circuit.
Channels that can be included in a conference include; the 64 channels of STi0 and STi1, and the channels of
the four expansion bus blocks. In fact any location in Local or Expansion Data Memory can be specified as in
incoming conference source, including the 32 tones or the DBT output. The Conference Party Control registers
specify which conference the channel is participating in, output attenuation levels, tone insertion and
conference initialization. See the description of “Conference Party Control Register (CPC1-15)” on page 65.
CM is also used to connect the Energy detect and DBRT blocks to incoming channels. The incoming channels
are specified in CML. The locations are listed below in Table 4. Channels can be transferred from Data Memory
in either Minimum or Constant Delay to the Energy Detect and DBRT blocks as specified in CMH. CMH
Message Mode and Output Enable bits are ignored for locations 70-72 of CM.
In addition CMH is used to specify the gain for the outgoing streams and the gain for the tones.
