Table 3-2 : Disconnect Type Parameter Values.
Telephone Interface Hybrid Pointer – parameters 26,51,76,101,126,151,176
This parameter allows the user to manually choose the set of telephone interface hybrid
coefficients to be used. There are 15 tables of entries (0-14), 1 for each ACIM setting with
the global compromise setting using the same table as ACIM=2. For each table there are
8 different entries (0-7) that allow for slight variation in the AC impedance presented by
the central exchange, and finally for each entry there are 2 sets of coefficients optimised
for absolute rejection (set=0) or for least mean square rejection (set=1). The value entered
should be the table of entries required x16 (equivalent to ACIM except ACIM=15 use
Table=2), plus the entry required x2, plus the set number.
