Engineering note pertaining to port addressing modes
There is a distinction between Group G and Group H functionality regarding
port addressing modes.
Group G
Standard address mode (0-15) can be any of the following:
•
•
•
•
•
•
•
Expanded address mode (0-159) can be either of the following:
•
•
The expanded mode addressing has no impact on the standard mode
addressing, that is, DASS2 D-channel (DDSL) 7 in the expanded mode can
exist with the Q.931 D-channel (DCHI) 7 in the standard mode.
Theoretically, it is possible to have 160 DASS2 D-channels and 16 other I/O
devices. In practise, however, there is a limit of 40 addresses in expanded
mode and 16 in standard mode, for a total of 56 addresses.
The port address numbers assigned to the NT5K75 and NT6D11AE
operating in expanded mode must not conflict with addresses assigned to
other I/O port types. To avoid potential conflicts and to simplify system
configuration, it is recommended that, in the expanded mode, the port
addresses for the NT5K75 and NT6D11AE avoid the standard mode range
(0-15) and be numbered in the range 16-159 instead.
