Introduction
The Model 6081RC card routes/bridges data from H.110 and Ethernet ports. The 6081RC connect to the
ForeFront chassis H.110 bus via mating midplane connectors (see
figure 21
).
Figure 21. Diagram of Model 6081RC and mid-plane
There are 32 H.110 ports available on the ForeFront chassis H.110 bus, Each of the function cards (i.e.,
6081RC, 3096RC, 6511RC, etc.) have access to all 32 ports on the bus.
Characteristics of the H.110 bus:
•
The H.110 bus is partitioned into 32 ports.
•
Each H.110 port can handle up to 128 timeslots, each timeslot is 64 kbps.
•
H.110 timeslots are unidirectional, for a full duplex link timeslots need to be defined for each direction of
transmission.
•
H.110 port numbers between two cards must match.
•
Direction of transmission between two cards must complement each other.
