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. |
