3-2 IMACS System Release 5.1.6 Server Cards
Model No. Running Head ACS-MCC Card Descriptions MCC Card
The FDL is a 4 kbps channel that uses every other framing bit of the T1 extended superframes.
When the FDL is used for remote system control via TCP/IP, T1 performance statistics are not
gathered.
The S A4 bit of the E1 frame alignment word is the first bit of time slot 0 of each frame. This
bit is called the national bit; it also comprises a 4 kbps data channel.
Figure 3-1.Typical MCC Application
If the FDL is used to transmit and receive information, a DACSII (6.1 or higher) must be used
to convert the FDL/IP information into DS0. On point-to-point circuits, the DACSII
is not
needed. The MCC can also be used to create larger “trees” in which the high-speed ports (C1,
C2, and C3) can interconnect the different ACS-MCC cards in the hierarchy.
3.2.1.1 Jumper/Switch Settings
The ACS-MCC card does not have any jumpers or switch settings.
3.2.1.2 Installing the Card
Insert the ACS-MCC card into one of the server card chassis slots (P1 to P3). The system can
accommodate up to three server cards.
