The second octet (the least significant octet) gives the internal circuit state
value of the CPC state machine. The internal circuit states are as follows:
Value State
Incoming call states:
0x00 Incoming call – idle
0x01 Incoming call – waiting for continuity
0x02 Incoming call – waiting for ACM
0x03 Incoming call – waiting for ANM
0x04 Incoming call – answered
0x05 Incoming call – suspended
0x06 Incoming call – waiting for RLC
0x07 Incoming call – waiting for Release confirmation from application
0x08 Incoming call – waiting for Reset response from application
0x09 Incoming call – waiting for Release request from application
0x0a Incoming call – overload
Circuit being reset states:
0x20 internally in an unknown state
0x21 circuit being reset – waiting for release complete (for a circuit involved in a group
reset)
0x22 circuit being reset – waiting for GRA
0x23 circuit being reset – waiting for RLC
Call in progress states:
0x44 call in progress – waiting for the application to release
0x45 call in progress – locally autoblocked
0x47 call in progress – waiting RLC (from CPC)
Incoming continuity test call states:
0xc0 incoming continuity test call – idle
0xc1 incoming continuity test call – waiting for CCR
0xc2 incoming continuity test call – waiting for REL
0xc3 incoming continuity test call – waiting for the application to release
0xc4 incoming continuity test call – waiting for CCR and waiting for the application to
release
Outgoing call states:
0x80 outgoing call – idle
0x81 outgoing call – waiting for continuity
0x82 outgoing call – waiting for ACM
0x83 outgoing call – waiting for ANM
0x84 outgoing call – answered
0x85 outgoing call – suspended
