This parameter defines which basic Channel Associated Signalling (CAS) protocol is used on a 2048 kbit/s primary group basis. The protocols defined are: USM (User Signalling Module), Transition Signallng R1 or R2D, DCMS to ISC Signalling (Q.50) and Circuit Supervision Signalling (Q.33). In DCME CAS is handled by the User Signalling Module (USM). Q.50 and Q.33 only apply to 2048 kbit/s primary groups. This attribute is characteristic of DCME. It falls in the TMN Configuration Category. It is a Read/Write attribute that has Enumerated Option values of CAS, Q50, Q33, Idle The default value is: Comment: Reference: G.763, Q.33, Q.50
Status in source: unspecified.
