Standard address mode (0-15) can be any of the following:
•
DPNSS1 (DDSL)
•
DASS2 (DDSL)
•
APNSS (LSSL)
•
Q.931 (DCHI)
•
ISL (DCHI)
•
SDI
•
ESDI
If the MSDL is used, standard mode can have a range of 0-63, and can be
any of the following:
•
Q.931 (DCHI)
•
ISL (DCHI)
•
ESDI
Expanded address mode (0-159) can be either of the following:
•
DPNSS1 (DDSL)
•
DASS2 (DDSL)
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 64 addresses using the MSDL with
Q.931, ISDL, or ESDI, plus 160 addresses using the expanded mode for
DASS2 for a total of 224 addresses. In practise, however, there is a limit of
64 addresses using MSDL with Q.931, ISDL, or ESDI, plus 40 addresses
using the expanded mode for DASS2, for a total of 104 addresses.
Presently, MSDL does not support SDI ports on DASS2, so the likely
configuration would involve a mixture of standard mode addressing, MSDL
addressing, and expanded mode addressing for DASS2. Such an example
could be as follows:
•
0-7 (8 addresses) in the standard mode
•
8-15 (32 addresses) in the MSDL mode
•
16-55 (40 addresses) in the expanded mode
