Circuit/CIC group supervision

Associated variants: All

Instructs the far exchange on the method of circuit blocking (ANSI) or whether blocking is maintenance or hardware failure related (ITU-T).

The type Ind field is encoded to one of the following values in ANSI:

0x00

BLOCK_WO_REL   Block without release

0x01

BLOCK_REL   Block with immediate release


The typeInd field is coded to one of the following values in BICC:

0x00
