The fields in the SiCirAssMap structure are encoded as follows:

Field

Value

mapType

Map type.

Defined values:

1 = MAPTYPE_1544   1544 k/bits digital path map format (64 kbit/s base rate)

2 = MAPTYPE_2048   2048 k/bits digital path map format (64 kbit/s base rate)

map1

map2

map3

map4

Map format.

Defined values:

0 = CIRCUIT_NOT_USED   64 kbit/s circuit is not used

1 = CIRCUIT_USED   64 kbit/s circuit is used.
