Port
Parameters
The Port Configuration screen (Figure 4-11) sets the operating parameters for each
high-speed port. The unit does not allow conflicting configurations for the DTE
ports. Therefore, the selections for each menu item are restricted to those that do
not conflict with the configuration of other high-speed ports or the T1 DTE Port.
The default is all channels disabled.
When channel assignment changes are made to the high-speed ports, to the remote
communication link, or to the T1 DTE, the unit reestablishes the mapping of all
channels. This interruption to traffic normally results in a brief burst of data errors
on other ports.
Channel Allocation
A detailed desription of this field is described in Channel Allocation on page 63.
Port #
Selects the slot and port X Y to be configured, where X =2 or 3 and Y= A to F.
Rate Multiplier
The unit can operate at any data rate that is a multiple of 56 or 64 kbps. When
N
×
64K is selected, the ones density requirements of the T1 network line must be
ensured. When N
×
56K is selected, the unit maintains ones density for the selected
DS0 channel.
DS0 Channel Assignment
Selects whether the DTE channel assignment is made as a CONTIGUOUS group
or as ALTERNATE channels. Selecting ALTERNATE assures ones density.
