A.2.1 Signalling access

This attribute characterized the protocol on the signalling channel at a given access point or reference point Values:

– manual;

– appropriate V-series protocol;

– appropriate X-series protocol;

– I-series stack of signalling protocols.

A.2.2 Information access

A.2.2.1 Rate

This attribute describes either the bit rate (circuit mode including transparent access to a PSPDN) or variable bit rate (packet mode) used to transfer the user information at a given access point or reference.

Values:

– appropriate bit rate;

– variable bit rate.

A.2.2.2 Interface

This attribute describes the interface according to the protocol used to transfer user information at a given access point or reference.

Values:

– appropriate V-series DTE/DCE interface;

– appropriate X-series interface;

– S interface;

– analogue 4-Wire interface.
