This parameter defines how CAS bit or bits are used to disable the echo canceller. This attribute is characteristic of SPNE. It falls in the TMN Configuration Category. It is a Read/Write attribute that has Enumerated Option values of None, A=0, A=1, B=0, B=1, C=0, C=1, D=0, D=1, E&M, FXO-GS, FXO-LS, FXS-GS, FXS-LS, signaling_scheme_1, signaling_scheme2 The default value is: Comment: This attribute is used in conjunction with EC_Per_Call_Control and is only in effect if the CAS value is selected. Typically, single CAS bit control is used when the transmission facility is 2048 kbit/s. Two bits (i.e., A&B) are typically used when the transmission facility is 1544 kbit/s. The values, E&M, FXO-GS, FXO-LS, FXS-GS, FXS-LS, actually represent A&B bit states. Two additional values are also provided for any customized configurations of CAS. None is used when CAS signalling is not being used. Reference:
Status in source: unspecified.
