DATA is BRI protocol group data block
BT is system BRSC pointer table
LAPD Protocol:
LAPD protocol group master head ptr (P_BRI_PROTMHTPTR) =
LAPD protocol group table (BRI_PROT_GRPTR[]) =
LAPD protocol group data (P_BRI_PROT_DATA) = 5
Per MISP:
MLB + MMB + SID + PIO + IO
where
MLB = 145 = size (PMISPLOOP_BLOCK)
MMB = 50 = size (P_MSDLMISP_BLOCK)
SID = 49 = size (P_SOCKET_ID_TABLE)
PIO = 5 = size (PHY_MISP_IOBLK)
IO = 259 = increase per MISP in size (IO_TABLE)
and
PIO is Physical IO block
IO is IO table
A typical large system will support about 5 MISPs.
Per DSL (Digital Subscriber Loop):
BB + ODAS + CLS + DD + BD + USID + TB + TF
where
BB = 26 = size (PBCSBLOCK) digital set
ODAS = 3 = data services addend to PBCSBLOCK
CLS = 12 = CLS: EFD, HUNT, EHT @ 4w each
DD = 17 = size (P_BRI_DSL_DATA) (nonkey function)
BD = 40 = size (P_BRI_LTID_DATA) (nonkey function)
