0x6388, 0x6389, 0x638A, 0x638B, 0x638C, 0x638D, and 0x638E—Group n Mapping
Control
Reset State
Only one description is provided for the Group n Mapping Control registers because the 7 registers have
identical bit definitions. The register offsets for the 7 registers are given in
Table 8-58. Register Offsets—Group n Mapping Control
The settings in these registers are applicable only when L3Map[1:0] = 01 in the Level 3 Mapping Control
register [addr: 0x6380].
Each of the 7 VT/VC groups can be configured to be either VT1.5/VC-11 or VT2/VC-12. Within a VT/VC
group, each VT/VC can be configured to be PDH (DS1/E1)-mapped or clear channel-mapped.
These bits control MUXes in the receive data path and conceptual switches in the transmit data path
