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
