To edit a line card slot, first enter the slot number to be edited. The channel card will supply the card
type and model information, which will be displayed on the screen, along with the existing line card map
(if any). The next prompt will be to select either a particular DS0, or all DS0s to be edited, or to clear all
DS0s. (To clear a range of DS0s, a quick way to designate the range is to enter the first and last DS0s
to be cleared, separated by a hyphen, e.g., “2-10”, would be DS0s 2 and 10.) After the desired DS0(s) is
entered, the system will prompt for entry of the type of function to be assigned to the DS0. The choices
are
Transmit , Receive , Both , and Clear . Except with intelligent channel cards, the prompt will ask next
for whether the application is to be Data or Voice . After the application is entered, the line card map will
then assign DS0s to the various channels of the line cards, all of which will be displayed.
The D/I Mux III allows up to seven (7) map configurations per line card. If, for example, more bandwidth
is required for data transmission in the evening hours when voice traffic is minimal, a separate map can
be configured for that time of day specifying data versus voice. Conversely, the daytime map can be
configured to preclude data transmission. With a seven-map capability, each day of the week can be
separately mapped, if necessary.
Having the capability of more than one map also facilitates map reconfiguration. An active working map
cannot be modified. In order to change mapping parameters, it is necessary to first duplicate the working
map. Changes can then be made to the copy, and the copy can then be made the new working map
upon reconfiguration. The commands used during this process are Copy Map matrix (
CM ), Set/edit Map
matrix ( SM ), Set the New working map ( SN ).
Figure 4-56 depicts the entire sequence included in editing a line card map.
