Domain Usage Considerations
The M-ACC is a DomainX module of the Avaya M770. The maximum number of
DomainX modules you can insert in the hub is determined by domain usage
considerations, as follows (M-SPX refers to either the M-SPV, M-SPX or M-SPS in
the following examples):
The Avaya M770 allows a maximum of 100 Domain Resource Units (DRUs) for
DomainXL (Left DomainX - slots 1-7) and the M-SPX, and 100 DRUs for DomainXR
(Right DomainX - slots 8-14) and the M-SPX. Each of the DomainX modules, as well
as the M-SPV module, has a DRU budget, as shown in the table below. When
planning your chassis configuration, calculate whether it fits the Avaya M770 DRU
budget.

Budget Calculation Examples
1
If you have one M-ACCF, seven M32-100 modules and the M-SPX you get:
3+7*12+10 = 97 DRUs. Assuming that there are seven modules on both the
DomainXL and Domain XR switches you get a total of 448 ports.
3+7*12+10 = 97 DRUs. Assuming that there are seven modules on both the
DomainXL and Domain XR switches you get a total of 448 ports.
2
If you have two M-ACCF, six M14-10F modules, an M2-1000 module and the M-
SPX you get: 2*3+6*6+15+10 = 67 DRUs. Assuming that you have the same
configuration on the DomainXL and Domain XR switches you get a total of 168
Ethernet, 12 Fast Ethernet and 4 Gigabit ports.
SPX you get: 2*3+6*6+15+10 = 67 DRUs. Assuming that you have the same
configuration on the DomainXL and Domain XR switches you get a total of 168
Ethernet, 12 Fast Ethernet and 4 Gigabit ports.
3
If you have one M-ACCF, five M2-1000 modules and the M-SPX you get:
3+5*15+10=88 DRUs. Assuming that there are six modules on both the
DomainXL and Domain XR switches you get a total of 24 Gigabit Ethernet ports
and 72 Fast Ethernet ports.
3+5*15+10=88 DRUs. Assuming that there are six modules on both the
DomainXL and Domain XR switches you get a total of 24 Gigabit Ethernet ports
and 72 Fast Ethernet ports.
4
If you have four M32-100 modules, one M2-1000 and the M-SPX you get:
4*12+15+10=73 DRUs. This is less than 100 DRUs and is therefore another
possible configuration.
4*12+15+10=73 DRUs. This is less than 100 DRUs and is therefore another
possible configuration.
