Note 29
A pointer has been added to fix memory. The name of the pointer is
“ISA_SID_MTHPTR” and is set to nil when SID is not defined for ISDN
routes.
A data block of 32 words is defined and accessed through the pointer if SID
is defined for at least one ISDN route in the system. This data block contains
the pointer to SID tables for each customer. The structure mapping onto this
data block is “ISA_CUSTID_TPTR”.
(size (ISA_CUSTID_TPTR = 100))
A data block of 128 words is allocated to each customer if at least one route
is defined as having SID. The structure mapping onto this data block is
“ISA_SID_RT_LIST”. The size of this data block is 512.
Note 30
Protected ISL trunk TN table = 1 + maximum number of ISL trunks defined
Note 31
The equation for calculating the protected memory requirements for customer
data is:
B + (X x (P + A))
where:
B = 320
X = number of customer groups actually defined
P = protected customer data = 255
A = auxiliary customer data = 59
If a background terminal is equipped, an additional auxiliary data block is
allocated which requires 43 words. This brings the total memory requirement
to 357 words.
