S78 and S79 - Outgoing Logical Channel Number (LCN)
Description
The setting of registers S78 and S79 should be adjusted if the network
requires a range of Logical Channel Numbers outside those specified with
the combination of these two registers. S78 and S79 combine to determine
the outgoing Logical Channel Number the packet layer uses to place a call.
The value is found using S78 as the two high decimal digits and S79 as the
low two decimal digits, or the value can be found by the formula S78 * 100
+ S79. If the resulting value is outside the range (4-4095), the value is
then assigned to the appropriate limit. The highest Logical Channel Number
is derived from the preceding formula, and the lowest is the value minus
the maximum number of channels supported plus one. The user can override
this factory setting and specify an LCN using the PAD selection command
(CALL).
