Configuring Model 6081RC H.110 parameters
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 mid-plane connectors.
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.
Figure 6
shows an H.110 bus interconnection connection between a 6081RC and a 3096RC. Two maps are
necessary for a full duplex link; both maps must have the same number of timeslots in each direction. In addi-
tion, the 6081RC H.110 port should connect to a corresponding 3096RC H.110 port. Similarly, the H.110
directions between the 6081RC and the 3096RC maps should complement each other, for example timeslots
in a “to H.110” port on the 6081RC, should go to timeslots in a “from H.110” port on the 3096RC.

Defining H.110 channels
From the standpoint of the 6081RC, H.110 ports and timeslot are assigned to PPP channels. To configure
H.110 channels, do the following:
1. Click on the H.110 link in the Configuration Menu pane (see
figure 4
on page 11) to display the
H.110
