6.5.2 Limited set of PLMN connection types (for TCH/F14.4 channel coding)

Figure 11 provides the information transfer protocol models for the identified set of PLMN connection types for support of TCH/F14.4. The description of models given in subclause 6.4.1 applies also to figure 11.

6.5.3 Limited set of PLMN connection types (for EDGE channels)

Figure 12 provides the information transfer protocol models for the identified set of PLMN connection types for support of TCH/F28.8 or TCH/F43.2 and figure 13 the models for the support of TCH/F32.0. The description of models given in subclause 6.4.1 applies also to figures 12 and 13.

When a TCH/F28.8 channel is used in multislot configurations, multiple EDGE multiplexing functions are applied on both sides of the air-interface; i.e. one multiplexing function  on each side of the air interface  is associated with each air-interface channel.

When TCH/F32.0 channels are used in double slot configurations, no rate adaptation is applied as the PLMN offers a ’64 kbit/s pipe’ between TE and an external network. When TCH/F32.0 channels are used in single slot configurations, the ITU-T I.460 rate adaptation is applied. (For details refer to 3GPP TS 44.021).
