Digital Subscriber Signalling System No. 2 - Additional Traffic Parameters: Signalling Capabilities to Support Traffic Parameters for the ATM Block Transfer (ABT) ATM Transfer Capability
This Recommendation is part of the DSS 2 famiiy of Recommendations; it specifies extensions to Recommendation Q.2931 [2]. It does not repeat states, information elements, messages and procedures contained therein, but only specifies extensions related to additional traffic parameter indications. This Recommendation defines the additional traffic parameters required for the support of the ATM Block Transfer (ABT) ATM transfer capability as defined in Recommendation I.371 [3]. This Recommendation includes the use of the DSS 2 signalling procedures for the negotiation of Peak Cell Rate (PCR), Sustainable Cell Rate (SCR), Maximum Burst Size (MBS) and Resource Management (RM) peak cell rate traffic parameters during call establishment. ABT precludes use of the DSS 2 signalling procedures for the modification of traffic parameters during the active phase of the call.
