A data block of 64 words is allocated for each customer if at least one route
is defined to have SID. The structure mapping onto this data block is
ISA-SID-RT-LIST.
Note 37 : Protected ISL Trunk TN table =
l+
maximum number of ISL
Trunks defined.
Note 38 : The protected customer data per customer defined is as follows:
B+(Xx@‘+A))
where:
P = Protected customer data block (255) (262 in Release 15)
A = auxiliary customer data (14)
B = 1000 for XN, XT, RT, and NT machines
320 for all other machine types
X = number of customer groups defined
If background terminal is equipped, an additional auxiliary data block is
allocated which requires 35 words. This brings the total requirement to 305
words.
Note 39 : No protected storage is required unless the system is equipped
with the Speed Call package (66) and the entry to MSCL prompt in Overlay
17 is greater than 0. In this case, the protected memory required for SCL
main header table is:
words required = N + (1 x A)
where:
N = 1 (number of header words)
A = number of SCL as defined in Overlay 17 (MSCL prompt)

in pool CDB (compool).
