Card Numbers

Figure 1-15. Typical Card Numbers in a Multiple-module Switchbox
Channel Addresses
28 Getting Started
The card number (cc of the channel_list) identifies the module within a
switchbox. The card number assigned depends on the switch configuration
used. Leading zeroes can be ignored for the card number.
In a single-module switchbox configuration, the card number is always 01.
In a multiple-module switchbox configuration, modules are set to successive
logical addresses.
The module with the lowest logical address is always card number 01. The
module with the next successive logical address is card number 02, etc.
Figure 1-15 illustrates card numbers and logical addresses of a typical
multiple-module switchbox configuration.
Module
The channel address (nn of the channel list) determines which relay on the
selected card will be addressed. Form C switch channel numbers are 00
through 31. The channels can be addressed using channel numbers or
channel ranges:
single channels (@ccnn);
multiple channels (@ccnn,ccnn,...);
sequential channels (@ccnn:ccnn);
groups of sequential channels (@ccnn:ccnn,ccnn:ccnn);
or any combination of the above.
Use a comma (,) to form a channel list or a colon (:) to form a channel range.
Only valid channels can be accessed in a channel list or channel range.
Also, the channel range must be from a lower channel number to a higher
channel number. For example, CLOS(@100:215) is acceptable, but
CLOS(@215:100) generates an error.
Note: Physical placement of the Module in the Logical Address
order is not required, but is recommended.
Card Number 01
Switch Module
Logical Address = 120
Secondary Address = 15
Card Number 02
Switch Module
Logical Address = 121
Card Number 03
Switch Module
Logical Address = 122
